C
No,
that
is
correct,
but
I'm
just
saying
no
problem
yeah,
the
design
that
we
have
is,
I
don't
even
think
is
patentable.
I
I
saw
the
patent
the
patent
is
is
on
the
bellows
thing.
I
mentioned
interesting,
we're
doing
it
simpler
and
we're
patent-free.
That's
the
beauty
here,
nice.
Now,
that's
a
little
bit
of
to
me.
This
is
absolutely
obvious,
and
I
once
again
I'm
saying
I
don't
know
why
nobody
does
it.
C
I
think
the
reason
why
nobody
does
it
is
that
nobody
can
scale
their
printer
systems
that
effectively
we
can
and
that's
why,
for
me,
I'm
saying
piece
of
cake,
scalable
modular,
so
I
think
we've
got
something
right
there.
It's
super
simple!
It's
like
I
mean
it's
no
brainer,
but
somebody
who
doesn't
subscribe
to
the
universal
access
or
who
doesn't
design
in
modular
way,
which
is
everybody
it's
a
problem.
C
So
this
is
where,
where
I
think
our
methods
shine,
our
methods
shine
at
the
very
large
scale,
because
we're
scalable
that's
like,
for
example,
with
a
tractor.
We
can
make
a
250
thousand
dollar
tractor
for
probably
like
25
000
in
parts,
whereas
for
a
small
tractor
it
will
cost
us
like,
like
maybe
5k,
for
a
tractor,
that's
equivalent,
maybe
like
20k,
maybe
there's
like
a
four
or
five
factor,
whereas
at
the
larger
scale
it's
10
and
better,
you
know
so
the
larger
we
go,
the
more
advantage
we
get,
and
that's
probably
why
that
hasn't
happened.
C
C
We
have
identified
very
clearly
the
problem
that
we're
solving
and
we're
solving
for
that
problem
and
here's
what
the
solution
gives
you,
I
think,
that's
the
kind
of
logic
we
have
to
use
and
if
we
make
that
thinking
credible,
we
can
make
get
a
lot
of
support
for
that
and
the
question
on
our
side.
The
onus
is,
are
we
very
sure
about
that,
and
I
mean
I
would
just
ask
anybody
here:
it's
like
okay
is
the
possibility
of
3d
printing
large
objects.
C
What
is
in
the
way?
We
know
some
of
the
things
in
a
way
it's
the
cost
of
filament.
You
can't
do
that
because
of
the
cost
of
filament,
so
we
know
that's
why
it
doesn't
happen,
and
the
second
part
is
well
what
about
large
existing
printers?
What
do
they
do?
Well,
they're,
very,
very
expensive,
the
the
high
temperature
ones
so
we're
solving
that
issue
by
low-cost
infrastructure
for
doing
that.
C
I
I
think
everything
lines
up
lines
up
here,
because
there's
not
a
question
whether
you
can
print
larger
and
larger
objects.
Yeah,
you
can
plastic
lumber
exists.
They
already
make
plastic
things.
This
is
the
advantage
that
you
get
the
plastic
lamp
lumber,
plus
the
composite
structures
that
they
make
from
that.
C
So
why
doesn't
somebody
just
injection
mold
these
panels?
Cheap?
Well,
because
fresh
plastic
resin
is
not
cheap.
It's
actually
at
the
dollar
pound
kind
of
level.
C
C
But
if
you're
doing
you
know
things
like
structural
panels
and
or
structural
insulated
panels,
that's
a
known
thing
in
the
building
industry.
Plastic
lumber
is
known,
I
think,
there's
some
innovation
to
be
done
in
terms
of
multi-layer
structures
that
you
3d
print
that
have
air
space,
they're,
actual
insulators,
there's
innovation
on
okay,
let's
make
the
plumbing
integrated
with
the
panels
and
other
things
so.
C
I
look
hard
for
for
errors
in
this
model.
Let's
open
this
up,
what
do
you
guys
think
is
the
like?
Does
this
work?
Is
it
gonna
work
like
what
what's
wrong
with
it?
Well,
what's
wrong
with
the
plan
like?
Can
you
really?
We
have
abundant
plastic?
That's
the
other
thing
like
I
just
looked
into
this
again
and
I
thought
oh
there's
only
so
much
trash,
but
no
there's
huge
volumes
of
trash
enough
for
the
house.
Supply
of
10
united
states.
D
B
C
C
C
Maybe
you
can't
do
it
for
that
specific
formula,
so
the
issue
is
okay:
let's
develop
formulas
that
are
robust
and
work
or
you
get
plastic
bales
that
are
just
a
composition
of
one
one
kind
of
item.
So
that's
a
definite
issue
like
a
lot
of
people.
Talk
that,
oh,
you
can't
print
with
plastic
because
it's
got
too
much
dirt
in
it
and
you
clog
the
nozzles,
not
an
issue
because
we're
using
very
large
nozzles
or
you
don't
care
about
this.
When
you're
printing,
big
things
you
you're
much
more
forgiving,
there's
definitely
code
issues
like
okay.
C
C
C
B
C
You
can
start
talking
about
like
start
a
recycling
company
right
now,
you
know,
take
people's
trust.
Hey
people
start
separating
your
trash,
there's,
not
a
recycling
center
in
town,
so
you
can
go
there,
just
a
basic
recycling
facility
yeah,
but
I
mean
in
terms
of
distributing
the
enterprise
like.
If
you
have
the
equipment
to
do
this
on
a
community
scale,
then
you
can
start
collecting
that
trash
on
a
community
scale,
because
right
now,
all
that
trash
has
to
travel
far
and
it's
part
of
the
reason
why
plastic
doesn't
get
recycled.
It's
too
too
hard.
C
E
Yeah
but
it's
hard
to
sort
it
decentralized
like
from
what
I
understand
like
you
know,
there's
a
lot
of
contamination,
someone
it
like
it
would
never.
C
B
B
C
We
can
buy
people's
plastic
too,
like
you
know,
we
can
because
we'd
buy
a
bale
at
10
cents,
a
pound.
I
mean
I'm
sure
some
people
would
do
it
for
10
cents
a
pound.
Even
if
they're
doing
a
good
thing.
You
know
they
just
save
all
their.
You
have
your
recycling
bins
every
so
often
you
get.
You
know
you
take
that
to
a
place
and
you
get
a
few
bucks
for
it.
B
C
Then
we
want
to
study
industry
standards.
So
what
are
the
best
projects
that
have
tried
to
do
this,
and
we
know
we
know
some
things
like
precious
plastic
or
there's
this
other.
So
let's,
let's
talk
about
precious
plastic?
What's
the
limit
there,
they
don't
have
3d
printers,
so
they
can't
be
as
flexible
as
we
can
be
in
terms
of
geometries.
C
They
work.
They
do
have
a
little
bit
of
injection
molding
and
things
like
that.
But
it's
not
really
necessarily
industrial
scale.
So
it's
it's
kind
of
more
like
hobby
and
art,
that's
a
good
project
but
doesn't
get
us
to
where
we
need
there.
They
did
start
making
these
blocks
that
they
compressed,
I
guess
compressed
or
injection
molded,
but
once
again
to
do
that
effectively
requires
huge
machinery
if
you're
going
to
do
it
in
an
economically
competitive
way.
The
3d
printer
allows
you
to
do
economically
competitive
product
with
very
minimum
infrastructure.
We
always
get
this
question.
C
Why
don't
you
just
injection
mold
this
stuff?
Well,
that's
heavy
equipment.
That's
some
forms
that
need
to
be
custom
made
for
each
thing
that
you
that
you
make
with
3d
printing.
You
have
none
of
that
restriction,
so
if
you're
making
a
thousand
different
things
you're
going
to
spend
a
million
dollars
in
in
molds
or
possibly
a
few
thousand
per
per
mold
here,
you
don't
have
molds
to
inject
mold
into
it's
free
form.
So
there's
that
advantage.
There's.
C
Some
other,
so
that's
the
study
of
industry
standards
for
what
we're
doing
here.
Industry
standards
would
be,
who
are
other
projects
that
are
really
doing
well
at
trying
to
clean
plastic.
So
we
should
look
at
that.
Someone
wants
to
do
research,
r
d,
on
that.
What
are
the
best
efforts?
There's
one
there's
some
plastic
project.
That's
doing
recycling
and
they're
paying
people
like.
I
think
it's
in
the
third
world,
a
lot
where
they're
paying
people
for
their
trash,
I'm
not
sure
how
much
traction
they
have.
C
I
think
they
got
some
traction,
but
obviously
not
too
much
because
there's
a
lot
a
lot
of
plastic
waste,
so
yeah
there's
there
is
not
a
not
a
good
project
to
that
has.
As
far
as
I
know
that
has
good
traction
on
the
on
the
problem.
If
there
are
we
should
we
want
to
contact
them
and
work
with
them
and
they're
going
to
be
proprietary,
so
they're
not
going
to
work
with
you
anyway.
B
C
Not
open
source
like
they
don't
they
have
a
revenue
model
but
they're.
You
know
they're
just
kind
of
hush
hush.
It's
not
collaborative
they're
they're,
not
saying
here's
an
open
franchise
of
how
you
can
do
this.
There's
a
lot
of
limits
this
and
we
can
do
like
a
study
of
okay.
Here's
how
collaborative
or
open
these
projects
are.
Precious
plastic
is
good
because
they
are
quite
open
and
that
is
open
source
equipment
there,
which
we
use
there.
We
use
their
shredder.
C
We
did
a
build
of
that
before
we're
going
to
do
a
bigger
one.
Now
they
do
have
a
shredder
that
they
cost,
because,
like
5000
bucks,
we
could
do
way
better
than
that,
but
we
do
want
to
study
the
industry
standards
and
so
a
lot
of
this
process
how
we
develop.
This
follows:
if
we're
developing
a
product
on
the
product
side,
if
it's
the
machines
themselves,
then
we
want
to
follow
the
development
template.
C
So
we
want
to
see
that
for
the
project
as
we
do
the
development
of
the
method
for
how
you
organize
an
incentive
challenge.
So
it's
a
replicable
model
that
is
like
an
enterprise
development
thing
and
we
can
actually
document
that
we
have
a
development
template
for
enterprise
too,
with
some
of
the
critical
assets
there.
So
we
can
start
seeding
that
so
on
our
page
for
the
incentive
challenge,
we
can
put
all
those
things
in
there
use
the
existing.
Remember.
C
Under
seed
home
2,
you've
got
the
top
template
is
developing
product
development,
template
and
then
below
that
is
enterprise.
Here's
how
you
would
develop
an
enterprise,
so
you
have
to
start
with
a
unique
value
proposition
you
get
into
things
like
product
strategy,
cost
structure,
business
plan,
all
of
that
there's
production,
marketing,
sales
and
improvement.
C
F
Swot
analysis,
fumes
from
the
melting
plastic
did.
E
C
Yeah
to
control
that
you
want
to
have
an
air
purifying
air
filter
system,
you
do
and
some
plastics
are
really
bad.
Other
plastics
are
not
and
there's
some
level
even
like
pla.
It's
not
not
the
best,
but
you
have
to
control
your
temperature.
You
can't
fry
it
because
then
you
decompose
the
plastic,
so
you
got
to
just
keep
within
temperature
range.
I
think
the
filter
thing
like
with
charcoal
and
things
3d
printers
use
that
currently
there's
various
printers
that
have
their
built-in
purifiers.
C
So
this
is
either
like
if
you're
doing
this
indoors,
you
definitely
want
to
do
that
in
a
purifier
with
an
air
purifier,
so
yeah
that
that's
a
technically
that's
that's
just
basic
filter
technology,
though
so
that's
not
particularly
onerous,
but
I
think,
probably
probably
that's
the
main
one.
That's
like
the
biggest
one
because
plastics,
given
that
they're
the
way
they're
made.
C
B
F
Now
I'm
also
wondering:
are
you
releasing
a
lot
of
carbon
when
you're
melting,
plastic
or.
F
Not
well
I'm
just
thinking,
because
a
lot
of
these
plastics
are
made
with
petroleum,
so
I'm
thinking
is
it.
Is
it
really
that
green.
C
No,
it's
not
it's.
It's
can
be
green,
there's
bioplastics
too,
so
part
of
it.
Once
this
succeeds,
then
this
could
force
more
of
a
direction
towards
sustainable
or
green
plastics.
E
C
The
idea
is
that
any
nasty
chemistry
or
any
bad
way
to
do
business
can
also
be
done
in
a
good
way
in
a
benign
way.
That's
typically
true,
so
this
would
enforce
the
direction
of
okay.
Let's
now
start
producing
in
the
world
more
sustainable
plastics
too,
and
then
at
the
end
of
the
day,
is
that
the
long-term
solution?
Well,
I
mean
for
now.
We
can
think
that
there
is
a
big
plastic
waste,
so
we
we
can
solve
that,
but
in
the
long
term,
how
do
we
really
want
housing
to
be
done?
C
That's
absolutely
good,
and
that's
where
we
got
the
compressed
earth
block
so
and
in
the
meantime,
in
this
process
we
can
build
a
lot
of
houses.
So
I
guess
a
lot
of
the
critique
might
be
like,
I
think,
probably
like
social
like
plastic.
What
plastic
housing?
Well,
people
already
live
in
plastic.
Housing
like
from
trim
to
roofing
or
siding
exciting
is
plastic.
Typically,
it
depends
what
depends
what
you
do,
but
there's
a
lot
of
plastic
in
the
house
that
you're
plumbing
other
things.
B
C
That's
that's,
got
vinyl,
siding
and
vinyl
is
one
of
the
plastics
I
think
pvc
and
vinyl
are
some
of
the
pvc
is
one
of
the
most
common
plastics
there's
polyethylene,
I
think,
is
number
one.
Pvc
is
like
up
there
top
three.
I
think,
but
once
again
and
those
are
things
people
don't
print
with,
because
you
can't
with
a
regular
printer,
you
need
the
high
temperature
chamber.
C
B
C
F
I'd
rather
be
in
a
plastic
house
than
a
wood
house
during
a
fire
really
yeah,
because
I
feel
like
it
could
melt
you
inside
of
it,
but
at
the
same
time
the
flames
would
stop
where
they
are.
I
feel
like
melting
is
your
problem,
but
whereas
wood,
the
problem
is
the
fire
coming
to
you.
E
C
You'll
you'll
melt
it
you'll
collapse
before
the
fire
reaches
you
I
don't
know
that's.
I
haven't
really
thought
about
fire
safety
on
that.
A
C
Interesting
point,
so
I
guess
so
cladding
so
part
of
part
of
the
solution
would
be
okay,
you've
got
a
house,
that's
got
some
plastic
in
it.
That's
all
made
from
the
recycled
streams
that
would
address
that.
If
you
want
to
go
all
plastic,
I
mean
you're
never
going
to
have
all
plastic
like
the
foundation.
Well,
I
don't
know,
maybe
you
can
do
plastic
foundations
too.
It's
like
rot
resistant
lumber,
but
better.
C
So
there
could
be
quite
a
bit.
So
I
don't
know
this
is
maybe
something
to
think
about
in
terms
of
marketing.
What
are
we?
Maybe
the
message
of
plastic
house
is
not
the
right
thing.
Maybe
we
say
we're
going
to
solve
the
plastic
issue
and
make
plastic
materials,
maybe
not
go
to
the
point
of
saying:
oh
we're
focusing
on
housing.
C
Well,
we
are
doing
housing
because
we're
doing
construction
materials,
but
we
might
not
say
like
stay
away
from
the
message
that
oh,
it's,
a
plastic
house.
D
C
Maybe
we
select
a
viewpoint,
that's
more
like
oh
we're
going
to
do
this
particular
thing
ponds
and
and
greenhouses
or
aquaponics
greenhouses
where
there's
a
lot
of
water
you're
not
going
to
get
into
the
risk
of
a
house.
If
people
are
concerned
about
that
issue,
house
fire.
C
A
And
it's
from
personal
experience,
it's
a
pain
to
work
with,
usually
because
it's
super
dense
and
bends
easily,
so
moving
it
around
is
like
moving
a
big
wobbly
super
heavy
slinky.
C
C
Yeah,
I
think
you
know,
like
I'm,
asking
what
what's
wrong
with
this
plan.
I
don't
know
it's.
The
thing
is
more.
I
think
the
other
question
to
ask
is
really:
can
we
do
it
because
it's
I
mean
it's
definitely
worth
something
worth
worth
doing.
C
The
question
more
appropriate
question
may
be
just
like:
how
do
we
get
to
do
it
and
we
have
the
savvy
like
the
once
again.
The
entrepreneurial
savvy
is
what
I
always
go
back
to,
which
applies
to
getting
anything
out
into
the
world
yeah.
Definitely
it's
that
part
that,
I
think,
is
our
our
challenge,
because
there's
plenty
of
good
ideas
that
can't
get
out
into
the
to
survive
for
various
reasons.
C
A
Yeah
well
the
open
source
nature
of
the
project.
I
think,
increases
its
viability
by
a
lot
because,
instead,
like,
if
you
were
doing
it,
proprietarily
like
starting
a
company
doing
this
you'd
have
to
hire
on
all
the
necessary
talent
which
is
going
to
cost
a
fortune
before
even
selling
anything.
C
Now
it's
common
that
all
the
software
companies
do,
do
it
and
contribute
to
open
projects
for
the
common
core,
but
not
necessarily
the
open
source
product
at
the
end,
but
common
core
open
core,
meaning
that
the
underlying
code
then,
like
amazon
and
facebook,
gets
built
on
yeah.
E
A
C
I
mean
it
is
open.
Source
is
a
very
effective
way
to
develop.
That's
a
known
fact,
and
it's
not
a
known
fact
for
hardware.
People
somehow
think
that
hardware
is
different,
but
once
you
digitize
hardware,
which
means
create
a
full
digital
model,
it
behaves
a
lot
like
software
and
it
can
be
non-scarce.
A
There
especially
seems
to
be
a
lack
of
open
source
development
hardware
when
it
comes
to
large
scale
and
industrial
equipment.
I
mean
there's
like
like
with
3d
printers,
there's
the
reprap
project
and
all
kinds
of
open
source
hobbyist
printers.
But
as
far
as
I
know,
there
aren't
any
large
industrial
size
printers
that
are
open
source
and
that
are
a
viable
project.
A
C
Complete
opportunity,
so
that's
how
it
works,
and
I
think
it's
largely
because
maybe
the
hobbyists
they
don't
think
of
that
skill.
Maybe
it's
largely
like
the
hobbyist
versus
okay.
Now
you're
going
industrial
different
story,
it's
more
than
something
you
can
do
in
a
spare
time
that
you
have
like
a
3d
printer
is
a
great
one,
because
it's
such
a
tiny
thing
very
manageable
for
a
lot
of
a
lot
of
hobby
people.
A
Something
something
you
said
the
other
day
caught
my
attention.
You
were
talking
about
how
this
project
basically
could
give
anybody
the
ability
to
make
their
own
living
right,
which
really
helps
with
that
kind
of
thing
because,
like
you
said
a
bunch
most
of
the
hobbyists
are
just
doing
it
in
their
spare
time
and
they
typically
have
a
full-time
job
and
that's
their
main
focus.
Whereas
if
this
allows
people
to
basically
make
this
their
main
focus,
you
can
get
a
lot
more
advancement,
yeah.
C
Exactly
a
much
shorter
time
and
that's
a
cultural
shift,
that's
what
we're
working
on
and
then
product
of
that
is
called
the
open
source
economy
where
everyone's
collaborating
on
product
development
and
eliminating
all
that
in
insane
waste.
That
happens
right
now.
So,
in
my
view,
that's
just
inevitable
that
that
will
happen.
I
mean
we
can't
continue
to
be
as
wasteful
as
we
are
today
for
much
longer
if
problems
that
we
face
are
getting
more
complex
and
it's
getting
easier
to
solve
them,
because
we've
got
more
technology
more
know-how.
C
So
so
we
need
to
upgrade
our
mental
operating
systems
towards
open.
To
make
that
happen,
and
I
think
a
lot
of
like
the
success
of
this,
this
incentive
challenge
would
be
to
to
raise
a
lot
of
awareness
on
that
one
by
the
rules
that
we
said,
we're
saying
we're
rewarding
you
for
collaboration
and
that's
that's
a
game
changer
right
there.
C
You
know
so
and
then,
on
top
of
that,
you've
got
the
technical
background
behind
it.
That
says,
oh,
it's
actually
going
to
lead
somewhere
to
real
economic
significance,
whereas
a
lot
of
the
socially
oriented
projects,
they're,
forgetting,
like
I
say,
always
say
that
open
source
forgets
one
big
thing
product
like
an
open
hardware.
You.
B
C
To
have
a
product
and
a
lot
of
the
social
movements,
they're
kind
of
forgetting,
I
think
they
kind
of
forget
the
same
thing
but
they're.
You
know
you
have
to
it's
about
the
livelihood
at
the
end.
C
Good
will
can
only
go
so
far
when
you've
got
to
put
pay
for
your
rent
and
and
have
some
food
in
your
tummy,
so
yeah
you
gotta
get
to
the
level
of
the
livelihoods.
Without
that,
we're
we're
not
we're
not
delivering
the
promise
of
open
hardware,
which
is
to
make
access
just
unprecedented
access
happen.
A
And
a
lot
of
those
like
you
know,
social
programs
and
non-profit
programs
rely
on
funding
from
big
companies,
usually,
which,
ironically,
makes
it
makes
them
sort
of
like
controlled
in
a
way
yeah
like.
If
the
big
companies
don't
like
what
they're
doing
or
it's
hitting
their
bottom
line,
they
can
just
pull
funding
and
the
project
dies.
Yeah.
C
That's
that's
a
subtle
thing
and
it
definitely
does
happen.
The
the
very
basic
thing
is:
how
can
you
expect
the
system
that
generated
this
wealth
to
also
transform
it?
That
would
be
basically
to
cannibalize
itself
yeah.
That's
not
a
good
incentive
structure
for
them.
They're
not
going
to
do
that,
so
it
does
require
innovation
from
the
outside.
To
make
that
happen.
C
What
you're
saying
that's
why
it's
like,
I'm,
not,
I
never
bothered
like
with
foundations
and
funding,
and
all
that,
the
other
part
being
it's
like.
We
gotta
replicate
this
and
scale,
and
you
can't
get
enough
funding
to
do
that.
Nobody's
got
that
kind
of
money
to
yeah.
To
start
all
the
all
the
good
work,
basically
a
thorough
economic
transformation.
C
E
F
Challenges,
I'm
thinking
I
mean
how
many
people,
what
is
the
market
for
it
like
would?
Would
you
guys
want?
Do
you
guys
want
plastic,
wonder.
D
E
Yes
for
your
house,
I
want
to
be
able
to
create
an
open
source
project
entirely
from
3d
printed
parts
and
not
have
to
source.
F
F
Yeah
I
mean
I'm
I'm
interested
in
like
using
the
the
plastic
for
other
things,
but
I
mean
I
don't
know
if
what
I'm
just
thinking
about
the
house,
in
particular
with
plastic
lumber,
because
now
that
he
raised
the
point
about
fire,
it's
got
me
thinking
about
okay,
collapsing
fumes
and
now
now,
I'm
all
of
a
sudden
paranoid
about
that.
C
Okay,
so
the
thing
it's
partial
answer
to
you
is
the
concept
of
rot.
I
mean
wood.
The
way
a
house
falls
down
is
things
rot
and
this
is
rot
resistant,
so
maybe
what,
if
you're
doing
the
foundation
from
lumber?
They
do
have
foundations
that
are
made
of
heavy
lumbers.
It's
rot
resistant,
so
that
could
be
one
one
aspect.
So
there's
definitely
areas
like
in
parts
of
the
house
like,
for
example,
siding
that
already
is
plastic.
It's
vinyl,
vinyl
siding,
which
is
most
houses,
are
built
like
that
right
now,.
B
C
In
the
us,
but
definitely
the
rot
resistance,
like
you
know,
we
built
the
pond
like
an
aquaponic
greenhouse,
it's
crumbled,
the
the
pun
has
kind
of
crumbled,
because
rod
gets
it.
Some
oyster
mushrooms
started
growing
out
of
it
right.
So
that's
a
real
issue
anywhere.
You
have
contact
with
the
ground
like
if
you
have
a
post
for
a
patio
outside
or
something
so
that
that
part
isn't
a
total
advantage,
plaster
plastic
lumber
like
say
you
want
to
make
a
pond
with
liner
easy
low
cost.
No.
B
C
That
part
is
good
and
maybe
not
not
others
where
you're
thinking
about
like
the
whole
dry
parts
or
framing
whatever.
That's
like
the
essence
of
the
house,
we
do
other
parts,
but
a
foundation
already
is
20
of
the
cost.
So
at
the
very
least,
you've
got
significant
cost
reduction
on
the
house
itself.
Right
as
the
the
outcome,
yeah.
F
Using
the
plastic
in
the
same
way
that
they
use,
I
believe,
I
believe
it
was
aircrete.
F
D
C
Yep
exactly
so,
maybe
maybe
that's
that's
the
product
value
proposition
that
we
might
go
forward
like
it's
a
for
foundation
forms
like
when
you
put
even
poorer
foundation
yeah.
You
can
use
this
like
if
you've
got
printed
shapes.
That
saves
you
a
lot
of
work
there
and
you
can
just
leave
it
there,
no
or
maybe
even
reuse
it
if
you
want
to
yeah
yeah.
I
do
like
that.
I
thought
about
that
too,
and
it's
a
great
use.
F
Yeah,
because
we're
not
farms
we're
not
mechanizing
ramder
construction,
nearly
enough,
it
just
seems
like
it
shouldn't
be
that
hard.
C
Of
a
lightweight
shell-
and
you
just
fill
it
with
dirt
and
you're
done.
You
pour
some
water
down
to
compact.
It
it
packs
down
dries
out,
don't
have
to
worry
about
rot
like
with
normal
wood.
There
you
go.
Maybe
maybe
we
pitched
that
so
maybe
we're
developing
this
new
construction
method,
it's
kind
of
like
rammed
earth
with
a
shell,
it's
yeah,
it's
a
different
thing.
It's
that's
like
insulated,
concrete
forms,
icfs
which
is
foam,
and
then
you
pour
concrete
into
it.
C
C
B
C
Yeah
just
that
with
fill
it
with
dirt
yeah.
That
would
be
it
so
maybe
yeah
so
whoever's.
Listening
to
this,
maybe
they'll
take
on
the
branch
with
the
the
insulating
plastic
forms.
Now
the
insulating
part
is,
if
you
print
multiple
layers
of
that.
So
maybe
you
can
have
this
form
multiple
layers,
so
multiple
multiple
layers
like
multiple
pane
windows
and
because
you
can
control
the
3d
printed
structure,
there's
only
very
little
connection
between
the
layers.
So
it's
highly
insulating.
C
A
Could
you,
in
theory,
like
fill
different
sheets
of
plastic
lumber
that
have
internal
hollow
spaces
with,
like
you
know
they
have
that
fiberglass
insulation
that
you
like
spray
in
to
in
between,
like
joists
yeah,
do
a
similar
thing
like
that
fill
up
the
panels.
You.
C
Can
do
that
everybody
stopping
cheap,
though
you
get
into
like
the
cost
of
like
extend
polystyrene.
A
C
Yeah
I
mean
like
the
equivalent
of
plastic,
peanuts:
plastic
peanuts
are
insulating
what
if
we
could
3d
print
plastic,
peanuts,
peanut-like
structures.
What
I
described
about
the
multiple
layers,
that's
kind
of
like
the
effectively
the
the
peanut,
the
peanut
have
peanuts,
have
just
tiny
air
pockets.
That's
why
they're
they're
so
insulating!
That's!
That's
all
about
how
this
works.
There's
a
lot
large
percentage
of
air
space.
C
C
There's
an
open
building
institute
presentation
on
that
I
want
to
show
see.
Am
I
sharing
my
screen?
C
E
C
C
This
is
cool
because
that
kind
of
stuff
is
quite
expensive,
the
multi-wall
glazing
and
that's
so
that's
an
insulating
plastic,
but
just
make
the
cavities
really
small
and
make
make
like
10
20
30
of
them
over.
C
You
know,
millimeter
wide
cavities
over,
like
30
of
them
only
take
like
three
centimeters
or
so
so
there
that's
a
valuable
product
right
there
and
the
4x8
sheet
is
45
bucks
at
menards.
C
If
you
print
it,
you
can
do
it
much
less
regrind.
You
could
get
for
a
dollar
a
pound
if
you're
recycling
cds,
if
you
have
a
bunch
of
free
cds,
then
you
can
get
it
for
free
print.
Your
3d
printing,
3d
printed
aquaponics
towers,
yeah,
that's
a
simple
filament
maker,
that's
precious
plastic,
shredder
and
extruder.
That's
existing
technology!
C
Or
recycled,
no,
that
was
just
new
pellets.
So
that's
cheating!
You
don't
want
to
do
that.
You
want
to
get
into
the
waste,
and
so
the
this
is
the
lyman
filament
maker
and
with
that
that
only
has
a
half
inch
barrel.
So
you
want
to
size
up
the
barrel
a
little
bit
to
one
inch
and
you
can
have
larger
flakes
of
regrind
and
that's
what
we're
going
to
build.
I'm
going
to
build
something
looks
like
this.
C
C
Because
one
of
these
is
not
not
too
expensive,
it
requires
a
motor,
an
auger
bit
and
a
heater
element
that
doesn't
cost
a
lot.
There's
a
temperature
controller
in
there.
That's
like
10
bucks
at
20
bucks,
but
not
expensive.
So
you
can
have
a
bank
of
these
spitting
out
filament,
and
these
make
like
I
think
we
did-
was
like
two
hours
for
a
spool,
so
you
could
get
12
spools
of
filament
from
one
of
these
filament
makers.
C
C
Yeah,
the
cost
is
actually
quite
negligible
when
you
look
at
the
numbers,
so
I
think
I'm
getting
like
two
cents
per
pound
or
so
here,
how
feasible
is
this.
C
Yeah
50
cents
per
pound,
but
down
to
about
three
cents
per
pound.
If
you're
running
on
a
solar,
solar,
pv
panel
system,
because
solar
pv
is
actually
cheaper
these
days
than
than
grid
electricity,
so
you
can
get
the
cost
down
to
a
few
cents
per
per
pound
and
compared
to
the
cost
of
the
final
product.
That's
that's
small.
C
The
roll
of
filament
is
two
pounds
and
that
costs
you
twenty
dollars
here,
you're
talking
about
using
these
numbers
here,
like
six
cents
in
terms
of
electricity
cost
for
that.
So
that
is
a
small
part,
and
this
actually
needs
to
be
updated
for
pretty
accurate.
It's
I
think
we
we
can
realistically
for
doing.
We
have
a
system
on
our
house
on
the
cdca
home
that
it
costs
us
two
cents
per
kilowatt
hour.
C
C
C
C
Well,
that's
what
I'm
getting
there
one
cents
per
kilogram,
so
the
ose
results.
This
is
what
we
did
a
couple
of
years
ago,
one
kilogram
spool
of
filament
produced
in
two
hours,
200
watts,
using
the
lyman
film
filament
maker
below
50
watt,
motor
150
watt
heater,
so
that's
200,
watts
of
usage,
so
about
five
cents
cost
per
kilogram
at
grid
cost
of
12
cents.
C
10
cents
a
pound
here,
so
I
I
talk
about
this
here-
purchase
garbage
bales
are
about
10
cents
per
pound,
so
you
get
one
of
those
those
ton
bells
for
like
100
or
to
200
bucks
or
so
for
a
ton
bail.
C
It's
still
an
incredible
markup
and
that's
because
one
they
they're
10x
higher
on
the
resin
cost,
because
virgin
resin
costs
10
times
as
much
it's
about
a
dollar
a
pound
and
then
they've
got
their
operations
and
then
marketing
and
sales,
and
all
that
using
all
proprietary,
expensive
equipment
and
it
ends
up
being
20
bucks.
A
roll.
C
And
that
points
to
one
one
amazing
product
could
be
filament.
Now
we
call
it
filament,
it's
filament,
it's
it's
pretty
crappy,
but
it's
great
for
what
we
want
to
do.
Maybe
don't
sell
for
20
bucks
out
for,
like
five
bucks,
a
pound.
C
Like
that
and
you've
got
a
huge
business
right
there
now
people
would
have
to
have
film
and
capable
printers,
which
are
which
we
are
producing.
So
even
with
the
1.2
nozzles
that
the
nozzle
size
is
big
enough,
that
you
can,
we
don't
get
clogs
clog
issues
we
gave
up
on
the
other
ones
like
we
used
the
prusa
extruder,
then
the
titan
arrow,
and
then
we
said
nah.
This
is
the
titan
arrow.
Was
it's
called
a
state
of
art
of
what's
out
there,
but
man?
C
If
you
clog
it,
you
have
to
take
apart
the
whole
thing
it's
designed
in
such
a
way,
so
we
said
uh-uh.
We
can't
do
that.
We
can't
have
a
print
form
and
spend
like
it's
only
like
15
minutes
to
open
it
up
and
put
it
back
together,
but
you
can't
be
doing
that
if
you've
got
100
printers
whatever
or
print
farm.
That's
just.
You
need
a
full-time
job
to
manage
just
just
the
print
heads.
A
C
We
should
probably
crank
them
out
I'm
printing
parts
right
now
at
my
house
forum.
We
can
look
into
that.
We've
got
a
couple
here
that
are
that
one
that
extruder
is
clogged
on
ours,
so
we
gotta
look
into
what's
happening
there,
but
I
was
getting
a
clog
on
our
printers
that
we
have
here.
C
C
So
yeah
we've
gone
through
a
bunch
of
like
the
value
proposition
points,
let's
see
where
we
are
at
right
now,
in
terms
of
so
let's
break
off
for
lunch
pretty
soon
and
then
come
back
and
actually
maybe
delve
into
the
work.
We're
kind
of
like
getting
introduced
to
the
whole
situation
here,
maybe
dig
down
into
some
of
the
work.
C
C
C
I
actually
say
just
just
for
your
reference.
I've
looked
at
a
bunch
of
this
stuff
do
would
encourage
you
like,
for
example,
if
you
go
to
mj
log
I'll,
probably
find
3d
printer
like
if
I
control
f
industry
standards.
I
probably
have
that
you
know
I
I
live
this,
so
I
probably
have
a
lot
of
this
stuff,
so
skid
steer
bulldozer,
open
air.
C
C
C
C
We
have
to
have
a
page
called
3d
printer
high
temperature
3d
printer
industry
standards.
Let's
see
control
f,
because
that's
I
mean
that's
our
starting
point.
It's
like,
if
we're
not
looking
at
that
we're
just
reinventing
the
wheel,
so
we
always
go
industry
standards.
That
means
patents.
That
means
other
companies
whatever
exists
on
it
open
source
projects.
C
So,
let's
see
high
temperature.
C
Name
it
you
name
it
every
single
plastic,
so
you
come
up
with
pei
peak
acetal
like
all
this
stuff.
C
Anything,
that's
that's
thermo,
thermoplastic,
any
temperature,
so
the
ones
that
are
like
450c
melt
temperatures
like
there's
some
really
high
ones,
but
the
chamber
on
that
is
going
to
have
to
be
like
yeah
like
around
200,
but
that
we
can
do
with
existing
like
with
the
current
concept
of
pi.
As
that
shield,
you
can
do
that
right
there
so
can
back
to
the
industry.
Science
look
scour
the
wiki
and
see
what
you
can
find
and,
of
course,
scour
the
internet
wherever
the
wiki
is
part
of
the
the
web.
C
So
maybe
start
a
page
on
industry
standards
for
high
temperature
printers.
I
know
I
put
a
page
up
there
about
cost
analysis
of
high
temperature
printers
and
when
we
say
cos,
cost
analysis
of
high
temperature.
Printers
temperature
is
like
above
150
and
then
you're
going
to
talk
about
size
like
I
don't
think
the
companies
that
make
the
large
insulated
printers
even
put
their
costs
online,
because
they're
so
high
that
you're
talking
about
hundreds
of
thousands
of
dollars.
C
So
we're
talking
about
competing
right
now
with
printers
that
are
in
a
hundred
thousand
dollar
scale
and
up.
If
we
do
the
four
by
four
by
eight,
so
it's
a
good
reference
point
to
say:
oh
in
our
video
and
by
the
way
we're
going
to
be
be
35
times
less
expensive
than
these.
Next
guys,
they'll
be
great,
but
we
have
to
have
that
concrete
data
to
say:
okay,
we
studied
our
system
and
here's
the
best
we
found.
C
Okay,
so
can
that's
ken's
just
to
review
wesley.
A
It
would
probably
be
good
to
have
some
kind
of
like
target
level
of
like
material
compatibility
for
the
printer
right,
like
a
temperature
range.
Basically,
that
has
materials
that
we
really
want
to
be
printing
with
in
it.
C
Well,
but
but
the
sky
high
goal,
it's
not
really
sky
high,
because
this
is
as
good
as
it
gets
we're
getting
to
the
top
of
what
there
is,
because
we
can
and
it's
not
it
doesn't
cost
us
any
more.
The
system
that
we're
talking
about,
I
think
the
highest
you
ever
have
to
get
in
systems
like
this
is
around
that
200.
C
I
don't
think
any
of
the
I
haven't
studied
deep
enough,
but
the
the
high
performance
printers
that
people
sell
they
they
go
up
to
those
kinds
of
numbers
like
maybe
150
or
so
so
we
actually
can
say
we
might
even
be
better
like
highest
temperature
in
the
world
just
because
it's
doable
easily.
This
way
I
mean
we're
simplifying
the
system
that
we're
getting
rid
of
that
bellows
and
stuff
we're
keeping
everything
outside
the
good
printers.
C
Keep
everything
outside
keep
an
insulated
chamber
and
yeah
I
mean
this
is
a
state
of
hard
as
it
gets.
So
we
don't
have
to
be
shy
about
that
one.
I
don't
think
that's
an
issue.
C
But
we
can
do
like
for
infographics,
we
can
say
oh
and
at
these
temperature
ranges
we
can
print
these
materials
and
you
go
down
into
the
highest
performance
ones,
which
we
say,
oh
by
the
way
yeah
we
can
print
those
too.
So
a
nice
informative
list,
an
infographic
on
that
part,
I
think,
would
be
very
useful.
C
C
So
that
way
you
say:
oh
okay,
it
can
reach
that
temperature.
It
can
do
this,
so
you
can
derive
that
and
we
can
show
some
examples.
There's
too
many
plastics
out
there.
I
think
the
simple
thing
to
say
there
is
is
just
the
temperature
range.
Anyone
in
the
know
like
who
cares
about
this
and
knows
this
they'll
be
like
holy
cow,
that's
good,
so
yeah
well,
and
the
people.
B
C
Don't
know
about
it
they'll,
so
if
somebody
doesn't
know
about
it,
we
we
can
say
oh
yeah.
This
can
print
with
with
anything
pretty
much
anything.
I
don't
know
if
there's
anything
that
we
can't
from
the
thermoplastics
outside
of
things
that
are
just
not
printable
period,
but
I
don't
know,
I
don't
think
that
exists.
I
mean
that
then
you
call
it
a
thermal
set,
it
doesn't
print
right.
It
just
does
that
once
you
can't
melt
it.
C
If
you
try
to
melt
it,
it
decomposes
before
it
melts.
Maybe
there's
some
plastics
that
have
like
a
very
narrow,
like
they
have
this
tiny
window
of
melt
and
after
that
they
just
blow
up
and
just
decompose
yeah.
C
I
didn't
haven't
looked
into
too
many
details
of
that
outside
of
knowing
that
some
really
valuable
plastics,
like
things
that
you
can
make
bearings
out
of
bushings
for
glide
lighting,
like
when
the
big
big
universal
axis,
those
all
those
kinds
of
things
and
pei,
which
is
our
print
print
surface
yeah,
you
can
do
we'll
be
able
to
print
with
all
of
those
by
all
means.
A
If
the
entire
body
of
the
printed
object
is
kept
at
glass
point
temperature
inside
the
chamber,
how
does
thermal
contraction
affect
it?
Then,
when
the
printer
is
cooled
down.
C
I
don't
know
I
mean
typically,
the
idea
is,
if
you,
as
long
as
it's
held
at
the
same
temperature,
you
don't
have
the
differential.
The
differential
is
what
makes
the
layers
separate
if
you
keep.
C
C
Plastics
on
a
regular
basis,
so
it's
like
that.
I've
never
seen
that
my
pla
shrink
after
it
cooled
for
example,
so
it
may
be
like
tiny,
but
it
may
hardly
be
noticeable
for
say
we
print
like
our
plastic
lumber.
We
know
the
thermal
coefficient
of
expansion,
then
we
say:
okay,
we
print
it
like
one
percent
bigger,
so
it
ends
up
at
the
right
size
or
whatever.
C
A
We
need
those
printed
with
abs
on
a
delta
printer
without
a
heated
enclosure,
and
it
gets
to
be
real
troublesome
when
the
with
the
thermal
contraction
when
the
print
gets
too
high
and
because
of
the
abs's
high
thermal
thermal
contraction
rate,
like
your
print,
will
shrink
by
like
five
percent
pull
itself
entirely
off
the
bed
in
the
corner.
C
C
E
In
there,
so
we
can
do
blender
in
multiplayer,
and
that
would
be
useful
for
either
like
editing
like
pretty
much
editing,
editing
what
editing
files
or
anime
like
so
one
thing
is
like
okay,
we
could
take
like
a
seed,
ecohome
module.
B
C
E
Like
the
functionality
of
blender
is
like,
in
my
opinion,
it's
like
five
or
ten
times
better.
It
doesn't
have
the
cad
aspects,
but,
like
you
said,
you
constructed
it's
not
good.
C
E
B
C
We
have
we
have
a
few
data
points
of
people
learning
freecad.
Within
an
hour.
I
you're
the
first
person
that
says
that
you
can
do
that
level
in
an
hour,
but
maybe
you
got
to
write
us
the
instructional,
for
it.
E
C
Yeah,
but
that's
what
I'm
saying
you
do,
the
things
that
freecad
is
good
in
the
square:
geometries
yeah,
of
course,
you'll!
Never
do
that
in
freecad.
You
can't
do
it
because
it
doesn't
have
those
functions.
So
I
think
the
simple
answer
is
both
and
that's
the
we
like
the
answer
of
both
a
lot
of
times
in
this
project,
because
it's
we
want
to
use
all
the
tools,
it's
inclusive
right.
So
that's
that
drives
with
inclusive.
C
So
I
don't
think,
there's
any
contradiction
but
to
say
we
all
migrate
to
it.
That
would
be
definitely
prohibitive
in
terms
of
anyone
being
able
to
to
do
it
unless
you've
got
you're
working
with
all
the
people,
the
blender
people
that
are
doing
that
so,
but
at
that
point,
we'd
miss
out
on
all
the
cat
people
that
actually
know
how
to
design
the
3d
printers
and
things
so.
C
C
C
So
what
I'm
looking
for
is
like
lengths
like
say
paul's
got
his
link,
and
that
means
yeah.
We
should
always
do
like
links
to
both
log,
the
wiki.
The
advantage
of
wiki
links
is
that
any
page
you
can
put
in
a
double
bracket
and
that
becomes
a
link.
So
it's
a
hyper
text
environment.
You
can
learn
a
lot
by
saying:
okay,
so
the
universal
axis
can
do
and
then
universal
access
is
a
link
and
so
forth.
You
can
transfer
a
lot
of
knowledge
because
you're
linking
to
readily
to
to
other
pages
princess
design,
toolkit.
A
D
D
Incorrect
but
it's
it's.
C
No,
it's
you
have
to
click
on
the
text
above
before
you
click
on
the
link
itself,
which
is
kind
of
weird,
okay,
yeah,
oh
yeah,
so
other
thing
about
the
work
lock
since
you're,
going
to
have
to
scroll
down
after
the
six
months
quite
a
bit
newest
on
top,
so
that
you
access
the
first
latest
thing.
First,
yeah
cool
stuff
toolkit
we're
studying
how
to.
C
C
Cool
yeah,
so
we've
got
a
little
bit
here.
We
talked
a
lot
about
kind
of
the
ideas
we
got.
I
think
we
got
some
forward
motion
on
conceptualization,
so,
let's
let's
break
for
launch
and
what
we'll
do
after
launch,
let's
just
hit
it
and
try
to
solve
the
things
we
kind
of
signed
up
for
and
try
to
put
in
a
little
bit
of
dedicated
development
time
to
it
so
be
back
here
at
111
or
after
one
hour
from
now.
