A
All
right
so,
hey
so
adam
with
the
people
from
sbarr,
they
said
they
were.
We
were
told
that
without
ip
protection,
or
at
least
the
claim
thereof,
that
they're
not
likely
to
fund
something.
So
I
was
just
asking
adam
about
this-
is
that,
like
everyone.
B
C
Everyone
that
you
don't
have
to
have
ip
like
a
patent
application
file
you
just
telling
them
that
we're
going
to
open
source.
This
is
probably
not
going
to
benefit
us
and
telling
them
that
we
and
we
don't.
You-
don't-
have
to
have
it
filed
by
phase
one,
but
by
phase
two
most
likely
you
would
need
something
filed.
A
D
C
Okay,
so
maybe
this
this
counselor
didn't
know
what
he
was
talking
about.
He
he
had
been
a
reviewer
for
12
years,
for
I
think
nih.
C
Yeah
so
sorry,
joshua,
you're
kind
of
cutting
out.
B
B
B
A
Kits
or
collaborative.
B
Further
collaborative
development
audit
training
business
incubation
on
the
topic-
I
mean
training
fabricators
to
now.
C
D
Good
idea,
if,
if
the
program
manager
can
either
knows
about
it
or
can
be
educated
to
sort
of
buy
in
then
then
you're?
Okay,
because
if
you
know
they
have
a
lot
to
say
about
who
does
the
reviewing,
and
even
if
you
can
nudge
them
into
people
that
are
at
least
not
antagonistic
towards
open
source,
you
have
a
you,
have
an
end.
C
Yeah,
maybe
this
counselor
was
used
to
nih,
where
you,
you
need
a
lot
of
funding
to
to
get
it
through
like
fda
trials,
and
and
so
you
need
some
ip
to
protect
yourself
from
from
what
does
that
call
that
someone
who
would
just
come
in
and
and
free
ride
right
all
right,
there's
not
much
of
a
free
rider
problem
as
much
in
the
3d
printing
space.
I'd
assume,
although
looking
into
rough
rap,
it
doesn't
seem
like
prusa,
is,
is
really
open
source
anymore.
A
Advantage
there
that's
that's
a
lot
of
choices,
they.
A
Their
deal
for.
D
A
D
Fairly
confident
prusa
is
still
pretty
good.
The
some
of
the
other
ones
have
kind
of
fallen
off
the
wagon
slightly,
like
the
you
know,
obviously
makerbot
and
those
guys,
but
oh
what
is
it?
The
other
european
one.
D
Yeah
yeah,
so
they're
they're
only
quasi
open
source,
they
patented
a
few
things,
but
all
the
other.
So
both
prusa
and
lulzbot,
which
are
the
two
top
ones
in
your
europe
and
us,
are
both
open
source
and
then
like.
The
under
three
is,
and
that's
I
think,
that's
the
most
popular
sold
3d
printer
of
all
time
and
that
that's
a
chinese
company
open
sourcing.
B
D
C
Way
if
they
force
us
to
do
it
where
they
we
say
it's
going,
there's
going
to
be
ip,
we
might
not
actually
develop
anything,
that's
patentable.
So
it's
really.
D
C
C
C
D
C
And
if,
if
you
resubmit
you
take,
you
take
their
their
advice
on
how
to
improve
your
submission,
I
think
the
submission
is
you're
more
like
50
on
your
second
submission,
so
yeah.
It's.
C
I
I
made
a
garbage
a
little
presentation
of
what
I
was
thinking.
The
project
would
look
like,
but
marcin
you
might
have
other
ideas.
Maybe.
C
C
Basically,
3d
metal
printers
are
way
too
expensive.
I
listed
a
few
here,
even
the
ones
that
claim
to
be
not
as
expensive
as
expensive.
Well,
they
still
have
decent
or
sorry
d
binding
like
cleaning
solutions
to
remove
the
binder
and
then
furnaces
for
centering.
So
they
end
up
still
being
you
know,
well
over
a
hundred
thousand
dollars
and
then,
as
far
as
cnc's
a
cnc
to
machine
steel
you're.
C
Looking
at
over
two
hundred
thousand
dollars,
there
are
some
cnc's
that
machine
like
wood
that
are
five
axis
for
you
know:
here's
one
for
forty,
two
thousand,
here's
one
for
seven
euro,
but
yeah
they
they
wouldn't
be
able
to
machine
steel.
C
So
the
idea
is,
if
you
were
to
print
print
with
a
metal
like
so
like
a
a
mig,
then
you
wouldn't
have
very
much
material
to
remove
and
therefore
you
could.
You
could
stand
to
have
low
feeds
and
speeds
for
removing
material
to
clean
up
the
welds,
because
the
welds
would
be
really
low
resolution
with
a
mig.
C
So
you
could
clean
up
those
welds
with
a
cnc
and
you
wouldn't
have
to
have
as
rigid
of
a
machine
because
you're
not
removing
very
much
material
and
since
you're
not
you're,
not
having
such
a
rigid
machine.
Then
the
price
of
your
machine
goes
down,
not
the
first
person.
To
think
of
this
there's
the
ability,
3d
I'll,
show
a
little
video
of
that.
C
A
C
B
C
Electricity
yeah,
so
the
the
problem
with
that
is
your
welds
any
imperfections
any
bumps.
They
get
magnified
because
the
the
bump
it
gets
closer
to
the
torch
head
and
so
you're
you're,
putting
down
more
material
faster
where
there
are
bumps
and
slower
where
there.
C
Yet
you
might
have
a
much
more
accurate
mig
than
I
do
yeah,
but
but
I
think
this
is
an
industry
issue.
If
you,
you
know
watching
wham
presentations,
that
they
are
like
industry,
that
does
this
right
now,
wham
printing,
they
say
that
that's
an
issue
with
with.
D
C
If,
if
you
plane
it
every
pass
and
then
just
getting
the
higher
resolution,
if
you
do
the
the
perimeters
there's
another
company-
oh
sorry,
so
one
more
thing
about
ability,
3d,
they
are
not,
as
far
as
I
can
tell
manufacturing
this
at
all,
they're
they're,
not
on
the
internet
other
than
they
had.
They
had
presented
this
at
a
show.
C
You
can't
buy
their
product.
Another
company,
a
big
metal
additive
out
of
colorado,
show
his
video
real,
quick.
C
So
you
can
see
it's
a
very
large
printer.
They
make
very
large
parts.
Here's
a
couple
of
their
parts.
You
can
see.
C
This
this
one,
I
think,
is
like
six
foot
by
like
10
or
12
foot
by
like
six
foot,
so
he
can,
it
was
the
dimensions
were
chosen
so
that
he
could
machine
or
print
ferrari
chassis.
I
believe,
anyway,
that
is
not
available
for
purchase.
He
is
apparently
making
money
by
by
building
things
for,
like
the
air
force
or
department
of
defense
or
something.
B
C
B
Is
that
would
you
be
interested
in
that
as
well,
because
if
we're
developing
this,
then
the
former
is
part
of
the
ladder.
B
C
B
C
I
mean
that
that's
all
right.
The
problem
is
at
least
I
wasn't
able
to
get
high
enough
resolution.
So
once
you
get
a
couple
layers,
you
start
getting
these
bumps
and
then
your
torch
head
runs
into
the
bump,
and
so
I
wasn't
able
to
to
actually
3d
print.
Very
many
layers
before
the
torch
head
would
run
into
the
part.
D
Sorry,
the
issue
of
it's
possible
it's
possible.
Well,
so
we
were
only
doing
everything
things
that
were
a
couple
inches
high,
so
we
didn't
have
that
as
a
major
issue
once
you
dialed
in
your
print
settings.
But
if
we
wanted
it
to
be
perfect,
we
found
that
after
each
run,
we
were
like
manually
cleaning
it
off
with
like
a
bristle
brush
just
to
like
tighten
it
up
a
little
bit
and
that's
how
we
got
our.
D
Between
layers
and
that
the
the
the
truth
of
it
is,
you
need
several
minutes
or
like
a
minute
or
so
between
each
layer,
so
that
you
don't
continue
to
build
up
heat
and
eventually
turn
the
whole
thing
into
a
puddle
depending
upon
the
part
size.
So
for
small
prints,
you
need
a
small
delay
in
between
each
layer
anyway,
and
so
you
can
can
clean
it
up
at
that
stage,
but
if
we're
going
to
completely
automate
it
for
large
prints,
I
think
a
lot
of
our
thermal
issues
will
go
away,
but
water
table.
C
D
D
C
One
more
thing
about
this
big
metal
additive:
they
talked
about
commercializing,
making
one.
They
could
sell
two
foot
by
two
foot
by
two
foot:
build
volume
for
three
hundred
thousand
dollars,
so
still
not
very
good
for
hobbyists.
You
know
way
out
of
our
price
range,
one
thing
lincoln:
electric:
they
have
these
industrial
robots
like
five
or
six
axis
robot
arms
that
they,
they
3d
print
yeah
and
they
have
very
high
resolution
on
the
right.
C
D
B
D
D
C
Yeah
average,
so
I.
C
Did
was
I
bought
this?
You
know
thousand
dollar.
A
A
A
Man,
it's
can
you
control
the
control,
the
weather.
B
D
A
D
B
C
All
right
so
some
experiments-
I
was
doing
it
just
in
the
basement,
were
I
bought
this
cnc.
You
know
cheap
thousand
dollars,
bob
cnc,
it's
actually
located
in
missouri
and
mounted
this
very
cheap
mig
torch
to
it.
It
was
actually
a
flux,
core
welder,
my
daughters.
C
I'm
in
a
meeting
so
I
I
changed
from
flux
core
to
a
solid
steel,
wire,
poked,
a
whole
nozzle
to
add
some
shielding
gas.
C
It
was
ac,
originally
put
a
rectifier
on
it
to
make
it
dc
added
a
solid
state
relay
to
turn
that
off
and
on
change
the
the
the
the
microcontroller
to
a
big
treetech
skr.
It's
a
common
3d
printer
board
and
then
wrote
up
a
little
program
that
turns
the
the
ssr,
the
solid
state
relay
on
and
off
to
turn
the
wire
feeder
on
and
off,
and
so
that's
how
we
can
3d
print
and
here's
some
results.
C
C
Maybe
a
a
stepper
motor
feet
would
be
better,
but
I
went
ahead
and
tried
machining
just
a
line
of
the
and
you
can
see
it's
just
got
a
cheap,
makita
router,
but
it
was
actually
able
to
mill
the
the
weld
but
the
the
pulleys
and
and
stepper
motors
that
move
the
router
around
were
not
strong
enough,
and
so
it
it
went
over
to
the
right
and
started
machining
into
the
the
build
plate.
C
Did
not
overheat
if
it's
even
with
this,
this
cheap
setup,
it
was
able
to
maintain
this
mild
steel.
B
A
C
C
The
only
the
only
nervousness
around.
D
C
That
you
know
with
the
welder
being
there,
if,
if
you
somehow
get
coolant
around
that
you
can
you
caught,
you
could
cause
a
short
maybe
to
to
your
your
motors,
your
controller,
you
to
the
frame
itself,
so
that
you
know
somebody
touching
the
frame.
You
know
I'm
just.
A
I
mean
it's
a
question
of
performance:
are
you
designing
for
hobby
performance
or
industrial
performance?
I
would
I
mean
I
would
start
by
saying
we're
going
for
industrial
performance,
not
hobby,
because
I
mean
at
a
similar
price
point:
I'm
not
talking
about
jacking
up
the
price
by
10x,
I'm
talking
about
similar
performance,
but
starting
with
assumptions
that
we're
we're
going
for
industrial
productivity
on
a
small
scale,
as
opposed
to
entertainment.
C
C
C
It
just
seems
if,
if
you
can
get
away
with
machining,
you
know,
maybe
you
need
to
get
a
more
expensive
bit.
C
A
Well,
the
question
is:
what
what
deposition
rate
are
you
interested
in?
If
that
deposition
rate
is
low
enough,
then
yeah,
you
can
absolutely
do
it.
I.
A
C
Is
a
is
going
to
be
a
very
competitive
method
for
deposition
rate?
It's
it's
laying
down
metal
much
faster
than
like
a
a
powder
laser,
oh
yeah
metal.
You
know.
A
C
Right
and
maybe
maybe
you
don't
need
to
mill
the
entire
part,
only
the
places
that
need
to
be
high
resolution,
if,
if
we
can
get
a
welder
to
to
print
welds
with
a
high
enough
resolution,
so
that
anyway,
the
phase
one
I'm,
I
think
just
making
some
welder
that
can
atta
a
torch
head
that
can
attach
to
any
cnc
or
you
know,
kind
of
universally
to
to
cnc
right
to
the
spindle.
C
That
would
be
nice.
I
think.
A
Making
or
using
all
these
shelves
sorry
would
we
are
you
suggesting
making
the
welder
part
or
doing
an
open
doing
an
off-the-shelf,
welder.
C
Option,
I
think,
an
off-the-shelf.
Well,
so
you
need
to
modify
the
welder
to
turn
on
and
off
the
the
feed,
the
wire
feed
and
to
get
the
the
high
resolution.
I'm
guessing
you'll
need
to
to
change
out
the
the
dc
motor
on
the
for
the
wire
feeder
to
a
step,
the
motor.
C
Yeah,
so
the
the
attachment
you
know
if
somebody
wants
to
to
convert
their
a
cnc
that
they
already
own
into
one
of
these,
they
can
just
attach
their
torch,
this
torque
head
to
it.
We
will
need
to.
C
A
A
Know
but
but
that's
for
that's
for
entertainment,
if
you
talk
about
performance,
you
would
be,
you
would
need
a
little
more
than
that.
I
mean
you're
talking
about
stuff
stuff,
like
with
welders
yeah,
I
mean
I,
I
work
with
welders.
Quite
a
bit.
I
mean
you're
going
to
need
that
if
you're
going
to
get
any,
you
know
anything
that
has
any
performance
to
it.
A
Maybe
maybe
that'll
be
innovation,
because
I
I
would
definitely,
if
I
were
doing
this,
I
would
not
start
with
anything.
That's
off
the
shelf.
I
would
start
from
scratch
because
it's
going
to
be
easier
and
cheaper,
but
if
people
already
have
one,
then
they
can
go
through
the
effort
to
convert
it
and
won't
work
as
well,
but
it
could
be
acceptable
yeah
that.
C
Innovation
yeah,
so
my
point
is
that
I'd
like
to
narrow
the
value
proposition,
yeah
get
really
good
at
one
thing
and.
B
C
Okay,
the
one
thing
that
you
need
to
be
good
at:
we
don't
necessarily
need
to
be
good
at
making
these
cnc's.
There
are
probably
hundreds
of
of
cnc
kits
out
there,
and
it
would.
D
C
To
give
people
the
option
to
use
whatever
kit
they
want
to
attach
what
we
have
yeah
for
phase.
One.
A
Yep,
that's
so
that's
that's
a
focus
indeed,.
C
So
for
phase
one:
that's
that's
how
it
is.
You
know
we're
basically
turning
it
into
a
3d
printer,
the
nice
thing
about
being
a
3d
printer,
there's
already
built
software
slicers,
the
the
software
I've
been
working
with
is
kira.
The
nice
thing
about
cura
is
that
they
have.
C
Function
that
can
be
used
to
as
a
it
already
has
it's
basically
planing.
So
we
don't
have
to
change
the
software
to
to
add
the
planing
feature:
nice,
okay
and
then
to
do
perimeters.
They
have
a
feature
where
you
can
do
multiple
nozzles
and
as
long
as
hold.
D
C
A
C
That
surface,
to
make
it
smoother,
I
see
so
instead
of
using
it
to
make
it
smoother.
Well,
we
are
making
a
smoother
we're
using.
C
C
B
C
C
C
A
C
C
If
I
was
confident
that
I
could
make
that
money
back,
you
know,
but
as
far
as
phase
two,
this
is
where,
where
things
get
more
expensive,
I
want
to
be
able
to
3d
print
tapers
and
overhangs
right
and
that
that
3d
printer
phase,
one
is
not
going
to
be
able
to
do
that.
You
need
to
you
need
to
angle
your
welds
on
an
overhang.
You
might
miss
where
you've
been
welding
and
go
all
the
way
to
the
base
plate.
C
C
What
would
be
ideal
is
to
have
some
attachment
like
phase
one
where
you
could
just
attach
this
to
any
cnc,
where
it
would
rotate
the
spindle
in
in
in
all
directions,
but
I'm
kind
of
down.
C
Yeah,
well,
it
gets
you,
it
gets
you
tapers,
so
you
can
go
tapered
this
way,
but
no
it
wouldn't
get
you
overhangs.
Okay,.
A
C
C
C
I
guess
I
don't
have
a
very
good
drawing
of
this.
The
idea
for
that
yeah
I'll
show,
you
sure
am
I
presenting.
Am
I
presenting
my
google
drive
now
or
do
I
need
to
you're
doing.
A
C
On
the
videotape,
okay,
let
me
present
a
tab.
A
C
This
is
the
original
I
gave
up
on
this
because
so
this
was
kind
of
designed
off
of
the
mostly
printed
cnc's
mpcnc
right,
but
I
found
that
these
3d
printed
parts
were
not
rigid
enough.
That
and
the
tubes
I
think,
just
at
these
large
scales,
the
tubes
are
not
rigid
enough.
C
You
really
need
what's
called
a
torsion
box,
but
anyway
the
idea
would
be
that
the
the
entire
x-axis
can
rotate
and
then
you
would
have
you
might
have
two
of
these
actually
to
make
it
more
rigid,
but
instead
of
tubes
it
would
be
like
a
piece
of
wood
like
a
two
by
six
or
something
or
maybe
not
that
thick-
I
don't
know,
but
anyway,
then
yours,
your
spindle,
could
rotate
around
the
other
axis
so
that
you
get
all
five
axes
and
then
for
a
z,
the
z
you
could.
C
Actually,
you
could
either
have
the
whole
base
plate,
move
up
and
down
in
the
z
direction
or
or
you
could
put
a
motor
like
a
z-axis
mounted
to
the
thing
rotating
here.
C
So
you
know
you
would
have
like
a
warm
gear
to
so
that
so
that
the
gear
would
stay
in
place.
C
C
And
and
basically
let
me
show
you.
C
C
C
C
Yeah,
you
know,
I
don't
know
if
they
have
issues
with
backlash
and
it
probably
depends
on
your
your
gear
ratios.
A
Just
a
simple
stepper
carriage
idler
base
kind
of
axis,
which
you're
talking
about
all
the
mechanical
we
can
do
in
a
piece
of
cake
like
we're,
building
one
inch,
rod
versions
of
that
solid
rod
so
for
four
by
four
you
can
get.
A
A
C
A
C
Wow,
this
is
like
all
welded
joints.
B
A
C
Thought
you
did
upload
it
to
my.
My
google
drive.
B
C
A
There
so.
A
Application
would
be
probably
one
1.5
or
2
inch
rod
size.
A
A
C
Okay,
so
your
frame
is,
is
made
out
of
rods.
They're
they're.
A
C
A
By
quarter
angle
held
in
place
by
3d
print
printed
plastic
pieces
to
the
point
that
we
can
weld
it
up,
basically
lay
up
using
3d
printed,
assist,
corner,
connectors
and
then
you've
got
a
four
by
four
by
four
frame:
that's
kind
of
self-aligned
with
the
3d
prints,
and
then
you
weld
weld
it
off
at
the
end.
Okay,
but
let's
see
universal
frame
so.
A
Here
my
screen
can't.
A
That's
great,
why
not.
C
Oh,
your.
A
C
A
A
B
You
can
yeah
and
then
for
like
much
larger
things,
which
is
probably
not
well.
This
is
actually
relevant,
for
this
is
the
trust
frame.
Rebar
trust
frames,
like
you
see
in
the
picture
you
prototype
those
they.
C
B
C
No
I'll
go
ahead
and
present
the
frame
you
can
talk
about.
C
A
A
B
B
A
B
B
A
A
C
A
B
A
C
Okay,
I'll
reach
out
to
the
the
program
manager
and
we
can
have
another
discussion
about
just
oce
and
or
osc
in
in
general,
about
some
of
the
other
grants
that
we
might
look
at
and
other
organizations
we
could.
We
could
talk
to
that.
A
Sounds
great
if.
C
No
they're
act,
they're
open
to
all
the
public,
so
yeah,
so
it's
kind
of
first
come
first
serve.
If
they
run
out,
then
there's
also
a
grant
that
just
became
available
called
the
fast
grant
and
september
1st.
They
get
funding
for
these
micro
grants
from
that
about,
like
2500
each
for
grant
writers
private
grant
writers.
So
you
have
to
get
your
grant
writer
approved,
but
they'll
give
you
2
500
for
you
to
spend
on
a
private
grant
writer.
C
You
have
to
go
to
a
a
class
like
a
workshop.
I
think
it's
a
two-day
workshop
and
if
they
think
that
you're
you're
business
makes
sense
and
you'll
that
then
they'll
fund,
it
they've
only
got
like
40
enough
for
40
grants,
though
so
when
it
it's
first
come
first
served
and
it's
not
available
yet
september.
1St
is
when
they
get
the
money.
D
A
C
A
A
C
It's
probably
a
decent
amount
of
the
writing
yourself,
because
a
lot
of
it,
they
just
don't
know
enough
about
the
subject
to
write
it.
You
know
and
you
if,
if
you're
transferring
the
knowledge
to
them,
you
might
as
well
put
it
down
on
paper
in
the
application.
B
B
C
C
B
A
A
A
A
C
A
2
500
grand
writing
grant.
B
C
I
don't
know
probably
those
private
grant
writers
they
all
offer,
maybe
different
levels
of
expertise
in
each
area.
So
you
know
you're
having
to
answer
questions
that
they
would
have
to
answer
questions
that
only
you
know,
so
they
can't
just
write
it
for
you
right.
C
Yeah,
but
I
can
you
know,
I
think
I
know
enough
about
the
project
to
to
get
it
to
a
decent
start.
The
one
thing
would
be.
We
would
need
to
set
up
an
llc,
you
know,
and
we
don't
we
don't
know
each
other
well,
but
I'm
fine
with
you
know,
setting
one
up
with
you
to
go
after
this
sbir.
C
A
C
Yeah,
I'm
going
to
reach
out
to
the
program
manager,
I'm
thinking
nsf,
but
there's
also
some
3d
printing
funding
through
the
air
force
in
the
army.
A
B
A
C
B
A
They
do,
I
heard
better
things
about
air
force
than
others.
C
Yeah
they
I've.
I
looked
at
recent
grants
and
they've
they've
actually
had
a
decent
number
of
3d
printing
technologies
granted
so,
and
I
I
think
they
offer
a
lot
of
help.
The
nice
thing
about
the
nsf
is
they.
They
have
a
short
form
that
you
can
fill
out
and
it's.
