hey guys in the last video I mentioned
we're getting a new 3d printing
sponsorship
well that 3d printer has come in the
mail and we're ready to unbox it!
like i said this is the only 3d printer that
can actually print continuous fiber
carbon fiber, fiberglass, and kevlar which
makes the print super strong and almost
equivalent to aluminum the material
comes in these gold ziplock bags and
this is just the fiber and we have
carbon fiber fiberglass and kevlar and
they all have slightly different
properties depending on what you're
trying to build now the material is a
really high quality nylon which consumer
3d printers nylon is one of the best
materials you can use for 3d printing
and this steps it up another notch so
one of the biggest issues with nylon is
it absorbed humidity which means if you
just leave it out in open air it will
actually suck water in which then
destroys your print quality when you try
and use it so this printer actually
comes with this pressurized watertight
Pelican case which you actually put the
roll inside and it comes out this to
keep all your material nice and safe and
community free
it would be a lot easier if you guys
were just entering watching you as one
sexy-looking 3d printer
alright so we just finished our first
print off of the mark 2 by mark forged
basically just a really simple wrench
for our lathe so let's go see if it
works alright so as you can see the
print quality is awesome you can barely
see the layers and it's super strong
because the the fiber in the middle
alright so this is a very basic part but
basically it was our first test print
from the machine so we didn't want to do
anything too complex alright so we've
had the mark 2 for about a month now and
we've actually started utilizing it for
some of our projects including printing
the gears for Riley's over powered
electric long board which we're going to
be doing a dedicated video on very soon
hot sonic we also managed to print one
of the most crucial parts for the Batman
grappling-hook winch and that allowed us
to do some pretty extreme tests what
you're going to see in the final video
that I'm coming out very soon
so now that we're pretty familiar with
how the printer works we want to do a
strength comparison test how much better
is the mark - compared to a normal
consumer 3d printer and to do that we're
actually revisiting our oldest Batman
project look familiar
we originally designed the fat man or
filing hook to be made of steel and
allowed us to rappel down some pipes and
then release the hook I even trust in my
life to it by hanging upside down and
pulling as hard as I could sure but the
real question is could we have used 3d
printing to do this project let's find
out all right to start we treaty printed
the rappelling hook using polycarbonate
filament which is widely regarded as one
of the strongest materials you can use
for consumer 3d printer now the question
is will this be strong enough to hold my
weight all right I do not have a good
feeling about this let's put some safety
glasses on already it's twisting
twisting
oh yeah it's kind of holding it don't
want to it's going to come right down at
me yeah I figured a better way of doing
this there you go
so you can't print this using a regular
3d printer but let's see what we can do
with the marker - as you can see the
limb of the bat arm just snapped right
off now this is definitely something
that the mark forged can help with
because with continuous fiber we'd
actually have reinforcements all the way
along the outlines which would likely
prevent this kind of a failure
all right let's utilize the Eiger
software that comes to the market Forge
to reinforce our part with carbon fiber
as you can see we're putting 20 layers
around the perimeter of the part to
really strengthen it up alright so there
we go we have a nylon Batman repelling
hook with carbon fiber reinforcement
around the perimeter of the park
so hopefully just be able to hold my
weight let's see alright let's give this
a shot
whoo a little bit nervous I think it's
going to hold compared to the other one
yeah this leg strap on
safety glasses this thing don't want to
spin
I bet there's quite the difference all
right take two whoo
not breaking its twisting a lot but that
carbon-fiber is holding strong and your
close-up of that so as you can see the
part is still twisting in the one AXI
and that's because the carbon fiber
reinforcement is only along the layers
unfortunately it's impossible to have
the reinforcement go the other way
because otherwise it wouldn't even twist
but as long as you design your parts
with layers in mind which you do for 3d
printing anyways you can have a very
strong structural part that you actually
use for things that you'd normally need
metal for plus if you attach to a bar
where it can engage fully it's even
stronger
how many can he do
how's it feel as you saw the normal 3d
print part using polycarbonate which is
supposed to be one of the strongest
filaments consumer 3d printer can use
still wasn't strong enough the carbon
fiber reinforced nylon part though from
the mark 2 was actually strong enough to
support my weight but I wasn't exactly
pulling off the feeling I had it the
original prototype made out of metal
that being said this printer is going to
allow us to make some really awesome
things that we normally couldn't do with
3d printing so I'm super excited to see
what were able to make with this 3d
printer if you guys want more
