Will 3D printed MTB parts break catastrophically? Let's find out!
3D Printers are awesome for prototyping, fitment, and small plastic items. Certain printers can even print stronger parts out of metal, but not mine. Today we’re going to print plastic bike parts, install them on a mountain bike, and test to see how strong they are.

If you are going to design bike parts, you might want to read up on design considerations for FDM.
3D printed dork disc would be appropriate 😅
Maybe fenders?
This was hilarious, thanks.
You know something is sketchy if even Seth is breaking out the safety gear / full face helmet
I feel like he’s putting too much torque on some of these. They would never be permanent solutions but could get you to the bike shop to get a real replacement. Also metal 3D printing might work great.
you gotta try using tpu!
Almost as good as cheap carbon parts. Sorry. No. not really XD
You should do a follow up with some designs from someone with more experience and industrial equipment.
There’s better choices than soda bottle for material choice
next vedio : bike drift
I made a friction shifter that didn’t snap, saving myself 6 whole dollars over the good shimano friction shifter.
A Bambu Lab x1 printer would be a great addition to BermPeak, Crazy fast and enclosure would allow you to use much stronger filaments. @bermpeakexpress
My commuter bike is covered with 3D printed parts. Light mounts, fender brackets, lock carrier, chain guard, bar end plugs. Nothing structural, high-stress, or safety-critical, but certainly very useful. Same is true of my car (even some engine parts such as the air intake) and a few parts on my motorcycle. 3D printing is nowhere near as strong as metal, but it often surprises me how much it can hold up to.
Print with abs
seatpost for electric scooter from plastic
If you are a million miles from nowhere with a broken down bike and a solar powered 3D printer, with care and caution you would get back home.
I hate being nit picky and annoying but when you said the filament name, you said it as “pet-G”, when it’s actually supposed to be pronounced as “P-E-T-G” (capitalized to say that you say the letter names)
Maybe a nylon or carbon filament would provide a bit more strength
LOL! I beleive you could make good 3d printed parts, though, but use lots of walls and high infill, preferably gyroid, since it’s strong, and probably another material, like nylon with carbonfibre (PA-FC). I doubt you can print that well on an open Prusa, but perhaps if you make (or buy) an enclosure for it, it should work.
Try different 3D printed material filaments!
I want to see a follow up with tougher filaments
8:48 you can tell he is twisting the handle bars to break it lol
Dude, this shit was awesome, i was literally Laughing Out Loud!
prby make great fenders
You should get some carbon fiber nylon and reprint these parts
woo….
Funny thing about this video. I would NEVER EVER do this on a plastic bike. But It’s late December here in Massachusetts and I haven’t been on the trails in months, though it honestly feels like years. And just SEEING the trails here gives me a warm fuzzy feeling. How many days till spring?
lol I can’t believe you didn’t die testing that last one xD
Great video though!
Petg is nice and strong but the issue with it is that the impact strength and elongation at break is very low. When PETG fails, it shatters. in this case PLA+ will probably work well for some of these parts (aside from low uv resistance) otherwise pa6-cf or gf will perform great for most of those parts.
I’d love to see a follow-up with v2 designs with better materials. Maybe with a guest mechanical engineer/ 3D printing specialist.
It would actually be interesting to see how far sensibly designed parts go, made by someone that knows what they’re doing.
have you tried to print this on a sla printer? Could be more durable as the fdm version.
Try again but print them in cf nylon I reckon with better design and materials you could push them a fair bit harder
That plastic seems really snapy, u sure that is petg. Maybe try puting more perimiters instead of more infil
3D printing might be good for a bottle cage, tool mount, or anything like that – MAYBE even a rack on the back to strap stuff dowqn too.
Should have made a whole frame 😆
Understanding material properties is a key pillar of engineering that was omitted here 😁
The lock on grips could really have a future for riders like me that need some really oversized diameter. Built up much thinker and wrapped with roadie bar tape, could be a comfortable solution
Part 2: Same idea, totally different printing material (not metal)
anyone else just dying of laughter while watching this? literally just watching a mirror of me! i love this dude! @berm peak esxpress
……heading to run A Line, on 3D printed crucial components…….
The seat clamp and stem (be it a street bike one) would work perfectly with 3D printing IMO. The jockey might be better with resin although the brake rotor and gear prolly wouldn’t work at all for actual use. With the 3D printed gun community I’ve seen people do the impossible. It just tends to be that the material governs the design process.
he should make a berm peak model
Addicks. Kingsbury.
Hey! Do you think you’ll ever revisit and revise the prints of the parts that weren’t up to the mark and then make a video on how the strengthened designs held up?
Would probably function much better with a higher grade filament….if it works to make guns, you can certainly make comps and grips….I’d probably stay away from friction parts though, as the won’t wear like metal
Have you looked at printables that’s what I use to find files for my printer.
Make a bottle cage
I printed a bracket so I could mount a light on the fork of my road bike. Made it about 4 years ago and it still holds up today like new.
WTF🤬This old man ROCKS LOL!!!!
Using design principles specific to metal parts to create plastic parts makes little sense. Design principles and material specifications go hand in hand.
That’s why the Romans didn’t use plastic swords.
I didn’t upload my designs because these are actual bike parts that could fit on a real bike. I’m not so sure it’s smart to put them out there. Also, I’m not sure why I referred to the hex size in the axle with an M before it. It is just an 8 mm hex.
Seth last year: will take it easy as to not continue to injure himself.
Seth this year: watch me make and test a home made 3D-printed stem.
