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!
how to print 3d printer, 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
information about it don't forget to check out their website it will link in the description below thanks for
