A
All
right,
my
good
people
recording
springtime
planting
out
some
peach
trees.
Actually
here,
okay,
but
let's
get
going
with
the
meetings,
so
development
team,
meeting,
April,
Tuesday,
April,
17,
2
p.m.
I'm
gonna
start
with
the
critical
path
narrative
on
the
recent
trip
to
I
made
3d
and
a
little
bit
of
hubbub
on
github.
No
just
some
questions
on
that.
Based
on
some
of
the
comments
before
john
is
absent.
He's
working
on
a
d3
d4,
the
PVC
frame,
ohio
ruslan.
A
A
A
A
Okay,
I
made
3d
workshop,
so
these
guys
are
professionals
they've
been
around
since
about
2014
since
they
started,
but
what
they're
doing
is
immersion
workshops
for
teachers,
educators,
teaching
them
how
to
build
3d
printers.
It's
a
good
case
of
benchmarking,
for
what
we're
trying
to
do
the
OSC
model
is
that
we
teach
people
to
to
produce
and
educate
at
the
same
time.
So
that's
that's.
Essentially
how
do
we,
you
know
in
a
big
picture?
How
do
we
transition
or
make
some
positive
change
in
society?
A
Well,
getting
more
people
to
build
stuff,
more
productive
people,
less
bureaucracy?
That's
the
general
theme,
the
open
source
micro,
Factory,
so
education,
slash
production
is
our
way
to
do
that,
because
in
the
grand
scheme
of
economics,
the
experience
economy
is
a
big
thing
that
comes
up
a
lot
of
times
as
automation
and
and
computer
work
fills
people's
lives.
People
are
still
very
hungry
to
do
what's
very
meaningful
and
that's
why
OSC
believes
that
a
huge
part
of
the
future
economy
will
be
where
more
people
get
involved
in
production.
It's
it's
a
choice.
A
I
mean
we
can
still
go,
centralized
versus
decentralized,
any
is
option,
but
it's
any
as
an
option,
but
it's
up
to
us
to
make
that
change.
So
we
believe
in
making
the
change
towards
educating
to
people
to
be
more
productive,
so
there's
less
less
inefficiency
or
less
bureaucracy
in
the
world
as
we
get
more
accountable
for
how
things
are
produced,
because,
ultimately,
it's
still
about
providing
a
modern
standard
of
living
and
based
on
natural
resources.
So,
with
that
said,
here's
a
an
immersion
workshop
that
the
guys
from
I
made
3d
are
running
I
met.
A
Lodi
Lodi
is
the
founder
of
that,
madam
at
the
Midwest
Renewable
Midwest
Renewable,
the
Midwest
RepRap
festival
three
weeks
ago
and
I
liked
it
so
I
liked
what
he
was
doing
so
I
decided
to
visit
them
and
I
did
over
two
days
that
this
was
a
two-day
build
they've
got
a
very
nice
print.
I
mean
it's
really
really
high-quality.
If
you
look
at
some
of
the
links
on
these
Facebook
posts,
you
can
see
how
fast
that
prints.
It's
really
fast.
It's
it's
quite
good.
A
Very
nice
design,
totally
transparent
industry
parent
case
and
but
but
also
very
simple,
to
build
in
a
sense
that
they
pretty
much
prepared
most
of
the
parts
for
you.
So
the
the
build
is
pretty
trivial.
It's
it's
an
easy
build
that
can
be
done
in
five
hours
by
inexperienced
people,
in
this
case
teachers
who
have
had
no
experience
with
3d
printing.
Now
for
our
workshops,
our
workshops
are
definitely
much
more
complicated.
We
go
much
deeper
into
the
build
itself
like
making
our
wiring.
A
You
know
drilling
holes
and
making
parts
that
are
not
already
built,
so
ours
is
harder,
but
still
we
can.
We
are
right
now
we're
at
about
eight
hours,
for
what
our
build
takes.
The
Prusa
i3
is
apparently
16
hours
if
an
expert
person
builds
it
and
40
hours
if
a
non-expert
person
builds
it
for
us,
it's
eight
hours
in
the
workshop
that
we
we've
been
doing,
sometimes
our
workshops
actually
ran
long,
but
but
it's
doable
in
eight
hours
and
we're
trying
to
get
it
down
to
about
five
hours.
A
So
it's
gonna
be
a
very
robust
model
that
you
can
do
within
a
school
day.
Just
think
about.
Like
9
9
a.m.
to
3
p.m.
and
a
school
day,
that's
there
will
be
another
Avenue
where
we
can
take
our
workshops
too.
So,
after
seeing
this
I'm
observing
that
wow,
there
is
a
huge
market
within
libraries,
schools,
any
education
institution,
any
staff
or
science
technology
engineering,
math
kind
of
program.
The
market
is
huge,
I
mean
everybody
wants
this.
It
spreads
by
word
of
mouth
and
Lodi
is
able
to
make
a
business
model
work
very
effectively.
A
I
mean
they
are
charging
1995
dollars
for
a
two
day
workshop
five
hours,
each
think
about
that.
So
they
are
providing
a
good
program
in
the
second
day.
They
they
do
work
on
explaining
it,
how
to
make
3d
printable
objects,
how
to
slice
them,
how
to
run
cure,
how
to
run
the
whole
tool
chain.
So,
in
the
second
day,
people
are
actually
designing
a
little
thing.
They
were
using
Tinkercad,
which
is
a
proprietary
solution
for
us.
We
can
do
there's
a
another
one.
A
So
things
like
that
now
for
ladies
workshop
with
I
made
3d
there
max
audience
is
six
six
people,
six
builds
or
possibly
he
said
up
to
like
10,
even
up
to
10
or
12.
If
they
have
two
instructors
for
us,
our
max
would
be
a
hundred
or
one
thousand
or
10,000.
I
mean
I
actually
envision
the
idea
of
of
a
new
sporting
event,
which
is
our
extreme
build
where
you
build
in
a
big
stadium
like
giant
stadium
and
then
smelly
new
jersey,
where
you
build,
you
have
just
these
extreme
extreme
builds
that
we
can.
A
We
can
do,
and
I
definitely
see
that
as
doable.
It's
basically
like
you're
right,
ethical,
big
event
which
could
we
we
could
then
apply
to
other
things.
So
you
can
do
that
with
3d
printing,
but
you
can
also
do
that
to
build
an
entire
village
with
10,000
people
in
one
one,
weekenders
stuff,
crazy
stuff,
like
that,
where
we
always
push
limit
of
a
swarm
bill.
A
B
A
What
you're
asking
is
a
very
pertinent
question
and
and
I'm
not
saying
that
this
is
easy
and
in
fact,
when
I
asked
this
question
to
Lodi
like
why
aren't
more
people
doing
this,
and
that
is
because
it's
it's
it's
very
hard.
It's
not
not
easy
at
all,
because
the
person
who
runs
this
workshop
has
both
to
be
a
technician
and
an
educator.
So
so
definitely
there's
challenges
pedagogically
and
practically
now.
As
far
as
the
like,
for
example,
to
address
this,
there
are
two
main
things.
First,
you
have
to
be
very
well
prepared.
A
Everything
has
to
be
well
proven
and
the
documentation
has
to
be
very
explicit.
They're
very
high
quality
and
Lodi
also
shared
the
idea
that
people,
just
after
about
three
hours,
people
just
stop
reading
any
instructions
they
get
their
minds
are
filled.
So
so
that's
where
he
said.
Oh
the
only
way
people
can
do,
that
is
language,
agnostic
instructions
where
you
don't
even
have
to
read,
but
the
point
being
that
the
quality
of
the
instructional
material,
written
and
guided
like
the
guide
in
during
the
workshop
has
to
be
be
very
well
well
developed.
A
And
how
do
you?
How
do
you
address
the
one
of
the
one
of
the
main
issues
is
when
there's
a
diverse
skill
set
range
in
the
inner
group
itself,
where
one
person
is,
you
know
twice
or
even
three
times
as
fast
as
another.
You
know
yeah
and
that
you
can
address
I've
thought
a
lot
about
that
and
we've
and
we've
done
this.
A
What
we
do
is
we
simply
for
some
parts
we
we
do
completely
together
and
we
work
those
parts
as
a
team,
so
there's
a
workflow
within
a
team
so
that,
if
one
person
is
stuck,
others
can
help
them.
But
the
general
idea
is
for
the
the
way
I
think
it
could
work
best
and
that's
what
we
try
to
do.
Is
we
go
step
by
step
and
we
do
not
allow
people
to
go
ahead
or
be
left
behind.
A
In
other
words,
if
there's
a
person,
that's
left
behind
the
ideas,
the
first
person
that's
finished
goes
out
to
finish,
goes
out
to
help
the
person
that's
that's
lagging
behind,
and
obviously
that
takes
some
good
organization
to
make
sure
that
we
know
who
is
who
is
going
forward?
Who
is
going
behind
but
make
it
clear
upfront
during
the
event
that
the
rules
are
as
such?
A
You
do
not
get
to
to
move
forward
you're
like
a
bunch
of
crabs
in
a
bucket
where,
if
any
crab
tries
to
jump
out
of
the
bucket,
the
remaining
crabs
actually
yank
it
down,
and
that's
actually
true.
This
is
true.
It's
I've
heard
that
story
being
told
is
like
Mexican
crabs
or
crabs
in
a
bucket,
but
but
that's
true,
we
actually
have
to
hold
the
person
who's
trying
to
go
forward,
hold
them
back,
and
this
is
fine,
because
the
idea
is
that
we
are
trying
to
finish
as
a
team.
We're
not
trying
to
say.
A
Oh
one
person
is
gonna
finish
and
feel
proud.
No,
they
we
have
to
have
everybody
finish.
So
that's
one,
one
technique
that
we
have
seen
work
and
it
works
pretty.
Well,
we
basically
have
as
soon
as
somebody's
done.
We
have
him.
Okay
go,
go
help
the
person-
that's
that's
not
done
and
make
it
work
like
that.
So
so
that's
the
challenge,
but
I
think
it's
definitely
addressable,
because
the
good
people
can
help
the
slower
people.
Does
that.
B
A
Exactly
and
that's
the
rules
here
are
simply
different
and
we
found
that
this
actually
works
really
well.
So
so
we're
that's.
Why
I'm
saying
we
can
do
these
very
large
endeavors
because
of
our
initial
experience
with
this
method
and
as
time
goes
on,
we
refine
it.
So
things
like
you
know:
every
person
has
access
to
language,
agnostic,
instructionals,
little
videos,
a
model,
that's
right
there
on
the
desk,
so,
for
example,
in
this
build.
A
If
anyone
was
stuck,
they
could
look
at
the
actual
finished
machine
to
see
if
there,
if
there
was
any
question
of
how
something
fits
together
and
then
the
guide,
the
person
who's,
the
leader
of
the
workshop
they're,
a
very
important
role,
because
they're
the
ones
that
observe
who's
who's
first
who's
last.
What
are
the
issues?
A
Does
everyone
have
what
what
they
need
and
actually
one
other
big
point
of
that
is
which
Lahti
emphasize
quite
bit
mm-hm,
and
this
is
how
how
they
do
it
in
five
sigma,
like
the
the
the
quality
control
methods,
the
to
layout
is
very
important
so
on
each
table
we
had
a
first,
we
started
by
laying
out
all
the
tools
very
carefully.
All
the
tools
were
ready,
available
and
accessible,
and
the
materials
were
organized.
A
They
they
typically
take
to
like
another
hour,
but
how
we
did
it
in
6:45
was
actually
a
little
longer
and
then,
of
course,
you
can
simplify
the
the
build
to
be
as
easy
as
possible.
So
the
main
difference
like
if
you
compare
this
to
how
how
we
do
it
for
us,
we
optimize
the
maximum
redundancy
of
parts
by
using
the
universal
axis.
A
It's
the
same
axis
that
you
build
on
both
XY
and
Z,
so
that
makes
it
go
much
faster
now
here
in
this
printer,
it's
very
complex
and
unique,
and
each
each
each
axis
is
very
different.
It's
it's
everything
is
very
custom,
so
this
is
not
a
kind
of
a
redundant
simple
design
kind
of
a
machine.
It's
it's
a
pretty
complex
one.
Oh
there's
a
lot
of
a
lot
of
information
content
within
a
design
itself
itself,
but
they
spend
a
lot
of
time
preparing
all
those
parts.
A
Whereas
for
us
we're
saying
you
pretty
much
source
off-the-shelf
parts
and
then
you
build
it,
build
it
all
and
for
us
it's
very
important
because,
for
example,
if
I
talk
to
you
about
a
thousand
person
build
right,
that's
crazy
amount
of
preparation
time.
If
the
amount
of
time
to
prepare
the
parts
is
large
like
like
like,
for
example,
I
made
3d,
they
they
do
a
lot
of
work
in
preparation
and
of
course
you
got
to
do
a
lot
of
work,
but
we
try
to
minimize
the
amount
of
work
that
you
need.
A
The
minimum
amount
of
pre-processing
that
you
have
to
do
in
order
to
make
it
feasible
like,
for
example,
their
frame.
Their
frame
is
laser-cut.
It
actually
has
labels
and
notes
on
the
frame
which
actually
serve
as
instructions,
and
they
tell
you
like,
where
the
wires
go.
They've
like
a
profile
for
where
the
circuit
goes
and
where
other
parts
go
et
cetera
for
us.
We
don't
do
as
much
of
that,
but
that's
why
we
can
just
take
like.
A
A
We
couldn't
do
probably
in
in
20
minutes
using
hand
tools
if
we
use
the
PVC
frame,
so
so
we,
our
philosophy
on
that,
is
to
make
it
really
really
optimized
for
the
local
source
ability
of
parts
and
just
to
give
you
one
one
example:
I
got
into
a
long
discussion
with
Lodi
about
this.
He
said
he
told
me:
I
asked
him.
Okay,
so
can
you
print
because
he
uses
a
lot
of
zip
ties
and
I
asked
him?
Well,
do
you
want
to
end
up
Oh
zip
ties.
A
These
are
the
zip
ties,
you
know
those
yeah,
so
he
his
like
main
main
build
technique
is
zip
ties.
I
mean
it
still
works
very
well,
but
I
asked
him.
Okay,
so
do
you
want
to
be
3d,
printing
them
they're
made
of
nylon?
And
he
said
he
says:
no,
that's
ridiculous,
because
their
two
cents
each
and
that's
where
I
differ.
I,
say
no.
A
No,
no
I
mean
still
very
much
valuable
because
then,
if
you
can
use
the
3d
printer
to
print
your
own,
zip
ties,
that's
actually
a
huge
pedagogical
value,
as
well
as
the
value
like.
What,
if
you
can't
get
zip
ties
in
your
in
your
country
or
something
like
that
or
what,
if
you're,
on
an
island
or
on
a
cruise
ship
and
your
zip
ties
fell
overboard,
you
know
so
so.
For
us
it's
about
easy.
B
A
B
A
A
Yeah,
it's
it's
an
option
where,
in
some
cases
you
will
need
it,
it's
just
I
mean
the
pole.
Point
that
we
try
to
emphasize
is
the
resilience.
The
reserves
is
that
you
have
more
than
one
option.
You
have
multiple
options
and
that's
always
good
in
life.
It's
it's
a
good
philosophy
and
the
fundamental
core
philosophy
of
OSC
that
that
redundancy
or
multiplicity
of
options,
diversity
of
options-
that's
all
good,
because
it
means
that
you
can
stay
out
of
trouble.
If
you
get
in
trouble,
you
just
go
to
plan
B
and
you're
still
perfectly
fine.
A
That
is
very
important
because
you
know,
ultimately
speaking
philosophically,
if
the
limit
of
that
is
warlike,
if
you
have
no
options,
you
end
up
going
to
war
and
like
the
political
limit
of
what
we're
saying
here,
it's
like
okay,
you
don't
have
resources
you're
for
you
to
steal
them
from
somebody
else.
Well,
we
don't
want
to
do
that
by
design
okay.
A
So,
let's
let's
continue.
So
that
was
a
great
experience
and
definitely
good
learnings
and
and
I.
Think.
The
the
major
encouragement
for
on
our
part
is
to
understand
that
wow.
The
markets
are
huge
like,
for
example,
when
I
came
back,
I
said:
okay,
maysville
high
school
is
about
two
miles
away
from
me
in
this
small
town
here,
but
they're
gonna
have
our
printer
pretty
soon
so
and
and
we
can
go
there
and
probably
if
we
do
a
workshop
there,
then
we
can
do
something
like
okay.
Mr.
librarian,
why
don't
you
invite?
A
A
We're
gonna
probably
have
more
more
interest
than
we
can
handle,
and
that's
why
that
kind
of
brings
up
the
the
pathway
here
like
while
you
see
that
our
we're
very
good,
very
consistent
on
the
reduction
in
our
number
of
total
development
hours,
we're
gonna
get
that
back
up
as
we
go
to
peep,
go
to
the
training
program
and
have
have
a
number
of
a
good
number
of
people
doing
the
workshops
as
we
start
to
grow.
So
basically
start
having
people
get
paid
for
the
work
that
they
do
as
a
means
to
bootstrapping
further
development.
A
A
Where
is
that?
No,
that's!
That's
just
if
you
go
to
the
page
called
critical
path.
I
made
it
a
point
to
emphasize
the
development
narrative
here
in
point
number
three
like:
why
are
we
going
about
it
this
way?
Well,
in
brief,
and
actually
I
want
to
go,
go
over
this
because
it's
pretty
important
like
people
are
asking.
Ok,
what
are
we
doing
this
year?
It's
the
level
1
micro,
Factory,
3d,
printer
CNC
circuit
mill,
laser
cutter,
3d
scanner,
filament
maker,
3d
scanning
means
photogrammetry.
A
A
Okay,
there's
a
link
in
a
chat
box.
If
you,
you
still
need
it,
but
what
is
the
so?
We
start
with
this
entry-level
micro
factory
on
the
path
to
the
larger
work
that
we're
known
for,
like
the
tractors
and
houses
and
so
forth.
But
the
relevance
of
starting
with
the
very
small
set
is
quadruple
so
there's
four
major
reasons
why
we
do
that.
So,
first
of
all,
it's
the
substance
of
a
one-month
immersion
program
in
September,
where
we
teach
OSD
files
to
run
workshops
now
number
two.
A
This
also
allows
us
for
rapid,
prototyping
and
extreme
design
jams,
so
rapid
prototyping
with
all
those
machines,
including
the
the
filament
maker,
that
you
can
actually
take,
scrap
and
recycle
you've
got
a
basic
basic
infrastructure
for
prototyping.
That
means
OSE
machines,
the
scale
models,
actual
real
3d
printed
products
like
like
cordless
drills,
etc,
an
extreme
design
gem.
So
what
I'm
thinking
is
now?
A
If
everyone
has
access
to
this
micro
factory,
then
the
design
jams
could
happen,
which
means
that
we
do
an
extreme
build
and
then
follow
it
with
some
development
work
using
the
machines,
like
one
thing
that
I
think
I
mentioned
that,
for
example,
even
developing
new
3d
parent
filaments,
like
ones
that
are
filled
with
metal
or
whatever,
okay,
so
but
number
three,
the
relevance
of
the
micro
factory
consumer
products
of
the
open
source,
everything
store,
so
click
on
that.
But
the
idea
is.
A
We
can
then
build
a
whole
wide
range
of
open-source
products
that
are
made
of
plastic,
off-the-shelf
parts
circuits
little
cuts
from
laser
cutter.
Small
laser
cutter,
there's
a
whole
range
of
products,
their
cell
phones,
aerial
drones,
microscopes,
robe,
small,
robotic
arms
cameras,
I
mean
name,
it
there's
so
many
consumer
goods
that
are
just
plastic,
elect,
plus
electronics.
Essentially,
we
can
do
all
of
that.
We
can
focus
on
design
competitions.
A
Where
say
we
we
have
a
number
of
OSD
fellows
active,
then
we
can
do
design
competitions
in
different
areas
around
the
world
or
around
the
United
States.
First,
okay,
so
that's
big
okay,
point
number
four!
We
can
actually
start
on
the
part
of
producing
materials
by
recycling.
Waste
plastic
with
a
filament
maker,
so
part
of
the
GBCs
is
that
we
use
natural
local
recycled
materials.
So
this
micro
Factory
at
level
one
allows
us
to
start
get
getting
into
that.
A
Imagine
we
collaborate
with
schools
and
we
set
up
recycling
programs
at
every
school
we
go
to
because
we
teach
them
how
to
recycle
their
cafeteria
plastic
and
actually
make
3d
printing
filament
that
then
they
use
in
their
science
class
to
build
little
prototypes.
So
that's
very
powerful.
That's
the
market,
for
that
is
huge,
okay
and
and
then
further,
the
level
of
1
micro
factory
fits
on
one's
desktop
and
it
can
produce,
or
it
can
be
networked
to
the
Internet.
Where,
then,
you
can
start
talking
about
machines
that
you
can
control
online.
A
That
means
you
can
students
start
up
on
demand,
3d,
printing
services
or
then
CNC
circuit,
milling
capacity
or
other
different
functions
as
we
go
forward,
so
that
would
like,
for
example,
the
CNC
circuit
mill.
That
would
be
a
great
enterprisers.
You
know
you
typically
get
those
done
by
by
big
companies
that
do
your
chemical
etching
or
whatever
photo
lithography,
but
I'm,
not
sure
anyone
does
it
with
an
actual
circuit,
know
that
and
that
could
be
a
small
viewable
business.
A
Now
pedagogically
the
value
lies
in
the
product
design
that
all
the
curriculum
that
you
can
make
around
this
product
design,
rapid,
prototyping,
reverse
engineering,
community-based
digital
manufacturing,
which
can
be
inserted
to
stem
that
science,
technology
engineering,
math
steam,
which
adds
arts
stream,
which
adds
they
add
the
AR,
which
is
read
and
write.
That
means
documenting
and
we
actually
cut.
If
you
click
on
stream,
actually
did
we
go
to
X
stream,
and,
let's
see
is
that
there
yeah
Google,
put
its
on
the
wiki
look
at
my
log,
4x
stream,
but
production-wise
open
sources.
A
The
open
source
everything
store
has
the
potential
to
become
a
powerful
forces
of
open
source,
distributed
product
development
and
manufacturing,
and
then
OSC
product
development,
wise.
The
extreme
design
jams
can
combine
extreme
manufacturing
workshops
with
prototyping
and
design
using
the
micro
factory
tools,
we
can
start-up
incentive
prizes
and
coopertition.
A
So
I,
like
the
word,
co-op,
Edition
and
competitive
cooperative,
a
cooperative
competition,
so
we
can
create
purpose-based
contests
for
producing
real
products
like
even
with
school
kids
that
could
transform
competitions
such
as
1st
or
vex
robotics,
into
direct
economic
relevance
by
practical
product,
development
of
presume,
ur,
goods
and
then
operations.
Wise
OSE
fellows
aim
to
address
the
need
for
regular
workshops
that
OSC
runs
and
then
they
could
run
the
extreme
design
jams
for
community
building
in
real
life
plus
further,
which
is
in
addition
to
the
virtual
development.
A
Because,
right
now
we
do
the
OS
e
dev
team,
which
is
virtual.
But
if
we
do
the
extreme
design
jams
on
a
regular
basis,
then
we
can
start
inviting
people
from
the
public
and
start
meeting
us
and
keep
the
whole
ball
going.
So
that's
that's
kind
of
the
development
narrative
for
which,
which
is
summarized
in
this
critical
path.
20:18
and
as
you
see
on
October
November,
there's
a
slew
of
workshops
coming
up
after
September.
A
So
that's
if
we
succeed
at
running
those
workshops,
that
would
be
great,
so
I
have
both
workshops
and
design
jams
happening
right
after
September.
So
that's
that's
awesome
and
then
on
a
CD
go
home
front
here
there
is,
we
deuce
do
still
plan
on
the
major
seed
eco
home
workshop,
so
that
would
be
a
one
week
of
immersive
training,
followed
by
a
one
week
of
build
of
a
small
micro
house
that
we're
trying
to
make
as
a
as
a
production
model
for
for
the
open
building
Institute.
A
One
more
note
here
is
that
on
the
precious
so
the
filament
maker,
so
now
you
see
the
the
new
new
and
improved
fret
I
call
it
precious
Lyman,
filament
maker,
so
a
mixture
between
precious
plastic
and
Lyman
filament
extruder
and
after
looking
at
that
carefully
I've
observed
that
the
precious
plastic
extruder
is
much
more
robust.
It
can
work
with
any
plastic
and
I
can
work
with
scrap,
whereas
the
Lyman
filament
extruder
typically
works
from
pellets
which
are
bought.
You
can't
make
them
yourself
easily,
so
the
precious
plastic,
a
grinder
extruder,
is
larger.
A
So
we
can
do
that
and
then
we
can
take
the
winder
part,
which
is
the
winding
of
the
filament
onto
a
spool
from
the
the
Lyman
filament
maker,
because
the
Lyman
version
has
that
well
worked
out,
whereas
the
precious
plastic
doesn't
have
the
filament
production
aspect
worked
out.
So
we
can
combine
those
together,
but
that's
that's
definitely
a
development
point,
so
that
leads
us
to
the
osce
merger
and
whatever
time
I
get
I
am
working
on
the
curriculum
for
that
and
working
on
a
book.
A
A
Definitely,
the
plastic
is
not
as
strong
and
would
have
to
be
reinforced
if
we
do
things
like
milling,
so
that
may
not
be
the
right
thing
there
and
maybe
we
end
up
with
the
metal,
but
it's
just
speculation.
We're
doing
this
for
now
and
seeing
seeing
where
we
end
up.
But
the
good
thing
is
that
all
the
parts
are
modular.
A
If
you
have
that
the
frame-
that's
just
one
of
the
many
modules
and
the
extruder
too,
we
have
flexibly
an
extruder
like
John-
is
doing
the
the
Prusa
i3
mk2,
that
brand
of
the
extruder
and
I'm
actually
right
now,
prototyping
a
version
of
the
plastic
frame
with
the
Aero
Titan
arrow
by
III
D,
which
is
a
much
higher
performance.
Extruder.
That's
designed
both
for
platfor,
thus
the
regular
plastics
as
well
as
the
flexible
filaments.
A
A
The
like
the
Prusa
i3,
mk2
II.
We
can
probably
build
that
for
more,
like
20
dollars
in
parts,
if
you
don't
count
the
motor
so
so
the
about
$100
difference
in
the
price
of
the
extruder
for
the
higher
performance
that
we
would
need,
and
but,
as
you
see
here,
we
can
fit
either
either
or
okay
and
now
actually,
looking
at
this
more
carefully
I'm.
Looking
at
seeing
that
there's
an
issue
here
to
uncover.
A
But
basically
the
idea
is-
and
this
is
actually
not
shown
here-
but
you
see
the
motor
our
standard
way
of
attachment
was
that
we
actually
stuck
the
motor
back
into
our
extruder
holder
and
that's
how
we
can
attach
the
motor
to
our
carriage
now.
Here
we
have
the
plastic
to
plastic
meeting
up
so
John.
If
you
review
this,
the
preferred
route
would
be
to
have
this
motor
sit
in
the
standard
holder.
So
if
we
go
to
the
D
3d
part
library
just
to
show
what
that
that
is
the
the
standard
way
we
were
doing.
A
This
was
using
this
holder
right
here,
this
holder,
where
the
back
of
the
motor
just
sits
in
it,
and
this
this
hangs
on
the
on
the
carriage,
so
I
would
actually
suggest
that
we
do
that.
Otherwise
we
need
if
we
go
with
this
route
here.
That
means
we
are
somehow
attaching
the
this
extruder
to
the
carriage,
which
is
not
exactly
that
easy,
because
somehow
we
have
to
do
it.
A
I
was
that
done
here,
I'm,
not
sure
how
it's
done
here,
but
I
think
I'm,
seeing
these
screws
here,
if
I'm
correct,
possibly
these
screws,
holding
and
holding
on
the
extruder,
but
probably
I,
would
say-
and
my
comment
would
be-
that
it's
probably
easier
to
just
use
there
standard
holder,
because
then
that
standard
holder
could
be
made
to
work
directly
with
either
this
extruder
or
the
titan
arrow
extruder.
So
we
do
know
that
this
extruder
works.
Well,
it's
the
crew
psyche,
I
3
mk2!
A
A
The
the
Titan
Aero
is
specifically
designed
for
the
flexible.
It
doesn't
have
this
long
pathway
here
where
the
filaments
can
actually
bend
and
and
the
difficulty
is
pushing
flexible
filament
because
it's
flexible,
it
will
end
up
bending
on
you.
So
this
long
length
here
is
eliminated
in
a
Titan
arrow
by
design
that
the
cooling
part
is
actually
above
like
right
on
this
upper
part
here,
but
anyway,
that's
technical
details,
but
we
can
use
both-
and
here
we
have
our
eight
millimeter,
eight
millimeter
probe.
So
that's
good,
but
yeah
I.
A
Just
attaching
the
motor
to
our
standard
holder
that
we
already
have
without
having
to
modify
the
way
we're
attaching
this,
so
you
can
literally
interchange
them
just
by
by
loosening
one
or
two
screws,
but
other
than
that?
That's
pretty
good!
Let's
see
anything
else,
John's
part
here
short
idlers
have
been
added,
so
that's
good
calculation
page
filled
out
so.
A
A
A
Not
sure
when
we
discuss
so
maybe
yeah
John,
if
you're
gonna
email
me
about
your
thoughts
on
that
I'd
like
to
hear
your
thoughts,
whether
you
think
this
is
good
to
go
or
whether
you'd
want
to.
If
this
is
simple
enough
to
mount,
because
I'm
not
sure
about
the
mounting
detail
and
I
guess
the
way
it
looks
here
this
plate,
I
see
uses
these
long
screws.
So
if
these
long
screws
are
easy
to
source,
they
are
an
extra
part.
So
that
does
add
another
pub
a
little
bit
of
part
count.
A
I
think
we
discussed
that
actually
before,
but
yeah
I
guess.
The
novelty
here
is
that,
after
thinking
about
it,
I
would
ask.
Is
it
possible
to
just
put
this
back
on
the
standard,
extruder
holder
and
therefore
we
can
remove
this
part
here
unless,
unless
this
is
actually
easier,
but
I
haven't
looked
into
this
in
detail
enough
to
tell
so
yeah
John,
please
get
back
to
me
on
that.
Okay,
good
stuff!
A
A
A
B
B
B
A
B
B
A
A
Yeah
well
I
mean
it's
a
good
point
to
say
that
we
develop
social
infrastructures
as
well
as
hardware
infrastructures,
I
think,
for
example,
with
the
3d
printer.
We
have
that
in
some
way
already
in
a
sense
that
we're
developing
the
print
cluster,
because
then
people
who
are
not
in
our
house
can
actually
rent
our
printer.
So
that's
an
example
right
exactly
what
you're
saying
yeah,
but
what
other
ways
could
we
do?
I
mean
definitely
in
a
plan.
We
have
at
least
thought
about
so
lending
libraries
I
mean
say
we
have
our
facility.
A
A
Yeah
yeah
I
mean
definitely
we
want
to
design
things
to
optimize
the
the
usage
like,
for
example,
if
we
like,
if
I
think
about
the
I
mean,
can
you
make
any
specific
comments
on
that?
For
the
like,
say
the
the
fellows
the
Ossie
fellows
after
they
get
training,
so
they
have
a
basic
set
of
tools
and
they're
used
like,
for
example,
the
3d
printers.
The
idea
is
to
build
a
couple
couple
or
even
more
3d
printers,
because
if
you're
gonna
run
a
workshop
like
say
you
do
a
couple
of
workshops.
A
Every
every
month,
you're
gonna
need
to
build
parts
for
at
least
say
twenty
four
printers.
So
that's
where
you'd
need
your
printers
will
be
running
a
lot
of
the
time
and
you
can
be
making
kits
for
others,
and
you
can
do
on-demand
printing,
so
we
can
definitely,
for
example,
use
that
3d
printer
full-time
and
the
filament
maker,
and
if
we
have
the
online
circuit
making
I
mean
the
circuit
all
those
tools
that
could
be
running
a
hundred
percent
of
the
time
once
we
develop
the
high
quality
products
and
services
around
them.
A
B
B
A
Right,
well,
then,
the
other
part
is
what,
if
that
cordless
drill
has
is
like
the
Swiss
Army
knife
of
cordless
drills,
that
you
can
interchange
the
head,
so
you
can
have
multiple
functions,
so
that's
also
another
way
to
extend
its
usability
or
design
the
cordless
drill
such
that
it's
actually
the
device
that
powers
your
filament
maker.
You
know,
so
you
can
think
a
lot
about
product
Ecology's,
how
the
things
fit
together
and
still
are
practical.
A
Yeah
yeah
I
mean
an
average
person
like
unless
you're
getting
involved
with
the
cordless
drill.
Quite
a
bit
I
mean
you,
don't
really
care
so
much
about
a
cordless
drill.
But
if
you're
a
builder,
if
you're
running
workshops
constantly
then
yeah,
you
need
a
lot
of
cordless
drills
like
we
do.
We
need
a
lot
of
cordless
drills
like
if
we
build
the
house.
I
mean
people
break
them
and
just
everyone,
everyone
literally
or
at
least
half
the
people,
have
to
have
a
cordless
drill
because
you're
doing
screwing
or
drilling
and
stuff
like
that.
A
The
biggest
one
is
lifetime
design,
the
flexibility
that,
if
you
break
it,
you
can
fix
it
or
you
can
extend
its
its
function
to
a
different
function,
so
so
lifetime
design
and
modularity,
because
that
I
mean
look.
Why
did
I
say
the
cordless
drill?
Why
don't
I
just
buy
them?
Well,
the
reality
is
our
drills
here.
Last
probably
like
six
months,
people
break
them,
they
drop
them
or
whatever
you
know
so
and
then
just
like
one
little
part
goes
goes
out.
A
It
could
be
as
simple
as
the
on/off
switch
breaks
and
you
can't
really
replace
it
because
it's
not
designed
to
be
replaced-
and
you
just
have
to
throw
the
thing
out-
it's
just
ridiculous
waste
of
waste
of
resources,
and
that's
that's
the
reason.
That's
the
thing
we
want
to
address
just
like
precious
plastic
talks.
A
lot
about
that
too.
He
says,
let's
recycle
stuff,
so
that
it
doesn't
end
up
in
a
landfill
reuse,
recycle
as
the
first
options,
because
which
is
okay.
If
we
talk
about
it
philosophically
more
vino,
Kardashev
scale.
A
Yeah
I'm
gonna
paste
the
link
and
I
think
it's
a
it's
actually
a
very
important
concept
now
that
I
found
out
about
it
I
see
how
relevant
it
is,
but
Kardashev
scale
refers
to
the
amount
of
energy
that
civilization
civilization
uses.
Well
right
now
we
have
a
throwaway
society
because
we
have
so
much
excess
energy.
We
are
not
in
a
shortage
of
energy
like
okay,
the
fossum
and
I'm,
not
talking
about
fossil
fuels.
Fossil
fuels
are
scarce.
A
B
B
A
So
we
don't
care
about
wasting
energy,
but
we
should
because
wasting
energy
is
you
know
it's?
It
takes
resources,
so
we
should
care
about.
It.
I
definitely
care
about
the
the
design
for
for
reuse
or
lifetime
design,
just
on
environmental
grounds
that
you're
not
generating
junk
for
the
landfill
and
all
the
issues
around
pollution
or
or
resource
extraction,
which
are
definitely
not
solved.
As
we
talk
about
humanity,
we
haven't
solved
those
things
we
still
have
to
go
to
war
over
oil.
A
That's
not
good,
but
the
car
of
scale
concept
allows
you
to
kind
of
frame
that,
because,
because
the
point
is,
we
have
to
become
responsible
because
we
can't
just
be
thrown
away.
Energy
and
I
think
having
a
handle
on
that
concept
allows
us
to
think
more
about
our
human
responsibility,
because
if
we
don't
care,
we
can
be
very
wasteful
and
we
have.
That
means
we
have
to
think
about
what
the
limits
are
that
we
would
like
to
impose
upon
ourselves.
A
Do
we
actually
want
to
have
like
10,000
times
more
people
on
the
earth
than
we
have
today?
Well
clearly,
that
would
pose
some
issues,
so
we
have
to
start
asking
well,
what's
them?
What's
the
good
population
level
or
resource
use
level
on
this
planet?
Should
we
settle
at
like
10
billion
like
we're
at
7
billion
right
now
is
10
billion
of
do
we
want
to
go
to
a
hundred
billion,
because
we
certainly
could
and
there's
plenty
of
land
like
if
you
don't
live
in
a
city.
You
understand
it.
A
There's
like
I,
don't
live
in
a
city
and
I
and
I
see
just
how
much
land
there
is
out
there.
That's
just
unused
and
there's
plenty
of
deserts
that
can
be
reforested
and
so
forth.
So
we
have
to
actually
ask
that
question
in
the
serious
way
and
I
think
resource
reuse
gets
us
at
least
thinking
about
that.
A
little
bit.
B
A
Absolutely
the
there's
four
tons
of
topsoil
on
average
are
eroded
every
year
per
acre
in
the
United
States
just
think
about
it,
four
tons
per
acre.
This
is
no
joke.
This
is
what
that
means
is
that
about
a
hundred
or
200
years
ago.
My
land
here
would
have
about
six
feet
of
topsoil
on
it
right
now
it
has
between
like
one
and
four
inches
of
topsoil,
and
we
took
those
measurements.
A
Right
right,
we
have
to
be
careful.
The
idea
is
that
we
want
to
leave
it
in
a
better
State,
not
in
a
worse
State.
That's
the
idea
of
regenerative
development
right
now
that
hasn't
people
don't
really
talk
about
regenerative
development.
They
they're
just
saying
you
know,
make
more
buy
more
stuff.
You
know
they,
the
we
do
not
have
a
regenerative
culture
at
present,
so
I
think
it's
part
of
the
transition
that
we
have
to
learn,
but
anyway,
that's
that's
philosophical
issues
that
are
very
important
to
what
we
do
at
open
source,
ecology.
A
It's
we
try
to
raise
those
issues
to
the
front
that
no
I
mean
the
destruction
that
we
have
right
now.
It's
it's
pretty
bad
like.
If
you
think
about
it,
like
the
topsoil
loss,
I
mean
pretty
much
like
all
the
agricultural
land
is
just
a
desert.
The
only
way
they
keep
it
alive
is
by
feeding
it
with
a
lot
of
chemicals.
That's
the
only
way
they
keep
it
alive
and
producing,
because
it
got
stripped
of
most
most
farmland
got
stripped
of
its
all
its
biological
activity.
A
Are
you
still
working
on
the
piping
work
because
I'd
like
to
request
I,
don't
know
if
you
can,
you
know
if
you
have
time
to
work
according
to
the
critical
path,
the
the
big
thing
on.
It
is
still
the
d3d
workbench,
if
you
could
put
some
time
into
that
after
you're
done
with
the
piping,
because
that
would
be
really
good
to
have
people
design
their
own
versions.
A
A
B
A
A
B
A
That's
just
yeah
just
for
piping.
That's
that's
correct
that
was
it
asking
yeah?
Okay,
that
sounds
good.
So,
let's
wrap
up
here
and
the
summary
is
yeah.
We've
got
our
development
narrative.
If
anyone
wants
to
comment
on
that,
please
do
so.
Click
the
go
to
the
critical
path
page
on
the
wiki
and
comment
on
this,
so
so
the
piping,
the
d3d
workbench,
is
right.
This
item
right
here,
a
lot
of
effort
is
going
to
the
immersion
program
and
with
that
hopefully
we
get.
A
We
reverse
our
consistence
downward
consistency
here
to
an
upward
consistency
and
in
two
weeks
is
when
I
aim
to
do
the
first
about
yeah,
it's
less
than
two
weeks
about
10
days,
I'm
gonna
do
the
first
announcement.
I
was
aiming
for
May
1st
as
the
announcement
of
the
initial
announcement
for
the
OSC
immersion
program,
a
five-week
five-week
immersion
on
site,
where
we
teach
you
everything
we
know
about
3d
printing
and
how
to
build
the
3d
printers
not
only
that
but
how
to
design
them.
So
that's
where
the
design
workbench
would
help
us
a
lot
now.
A
We
can
definitely
teach
people
how
to
do
that
by
simply
importing
the
modules,
but
it
would
help
us
a
lot
if
we
have
the
the
workbench,
which
makes
it
easier
and
more
parametric.
So
that's
that's
the
relevance
other
than
that.
Thank
you
very
much.
We'll
continue
next
week
then
so
see
you
then
bye-bye.
