How to Make a Forged Carbon Fiber Part - 3D Printed Mold
HTML-код
- Опубликовано: 20 сен 2024
- I make a forged carbon fiber door handle for my bush plane build with less than $30. I designed, 3D printed, and laid up the parts using some scrap carbon fiber weave that was going in the trash.

Great video. Easily one of the best I've seen for using a 3D printed mold. Most guys just show the mold, not how they make it. If you get bored, I'd love to see a more detailed mold tutorial.
Wow, thanks! Yeah I'm definitely planning to do a more in depth, so stayed tuned on that one!
Try adding a 1mm chamfer to the edge where it meets the build plate on your printer and that should eliminate the step of having to remove flashing!
That's a great idea! I've done that in the past, and clearly forgot about it, haha. Thanks for the tip!
@@letsbuildthis no problem, I can't take credit for it, just something I picked up watching Slant 3D! He's got a great channel with a lot of helpful advice!
Really enjoying you sharing the maker side of experimental aviation. Im off to see if you have a shop tour video.
Awesome, glad to hear it! No shop tour video yet. TBH, the shop is a bit a mess and it drives me crazy, but perhaps I can do a shop video in the near future. Cheers!
@@letsbuildthisI know how that is. Mine has been so discombobulated this summer that it is unusable for some projects
Very nice! Did you do a stress test on these parts to see how strong they are since they are just prototypes? Thanks for sharing!
Hey chiparooo, not yet, but will include in a future forged carbon video. I can’t even bend or break with my hands (not very scientific I know, haha), it seems very strong though.
What makes this forged as opposed to cast?
Good question... not a term I came up with, just the universally used term around a newer composite process for carbon fiber. However the best analogy I can think of is a cast piston vs a forged piston. One is only pored, the other has had forces applied to it. So, I generally agree that the term "forged" carbon is not way far off in the fact that it's put under pressure as well.
The marketing team at Lamborghini is why it's "forged" :P
Your video is very interesting and well done. What filament are you using for the mold? Just recently I ran across a new filament from Bambu Lab in another video. You may also be interested in it, ruclips.net/video/A5PZclEcLWw/видео.htmlsi=VmhQ5of6jM-FJMaL I ordered some of it from Bambu Lab but it is on back order and I feel confident of the filament since they sell it. I am like you mostly interested in engineering uses of 3D printing. And we have two X1 C printers. Also like you I model all the parts for myself but we use SolidWorks which is comparable to your software too. Good luck on the approach to carbon fiber forging!
Thanks Glenn! Just using the standard PLA for now. If I throw them away, then the cost is low. If I Improve the mould, and can reuse I will definitely consider some better materials. I just picked up a PC-CF filament, but without an enclosure on my printer I don't think it'll work very well. I had the chance last week to print some parts on a X1 and I'm super impressed with the quality and even more so with the speed. Needless to say, the Bambu is likely in my near future. Thanks for the dialog and encouragement!
@@letsbuildthis very nice. i've just done this with some bicycle frame dropouts and I was dissapointed how hard they were to demould. but I had not used a draft angle and did not split the mould like you've done so I guess thats the main reason. BTW for low stress applications like the handle, I'd use PC-CF. I've used it on bikes in certain applications and its very strong. if you enable many wall layers then the outer surface of the object is very strong as you ensure the (shortish) CF fibres are aligned to the surface and so perfect for resisting bending. good luck.
How could the bottom split into two parts when the shaft that forms the hole is split half and half with the two lower moulds? ruclips.net/video/kmyJMVr_iB8/видео.html
Good eye, lol. Yeah total design flaw. I split the mould down the middle as the back up in case I couldn’t get the part out. Welp it was all moot because the boss held it all together. No big deal though because they’re low res prints and they broke in many places anyway. Next design will have the boss on one side.
Great video! Perhaps finding a way to make the print layer lines run parallel to the direction in which you intend remove the part will help for de-molding. The tiny ridges that the layer lines form unfortunately just add friction/ grip.
Thanks! Yeah, that's a good suggestion. I'll take a look for the next set of molds.
