I've had the idea of 3D printed lugs for a couple of years now and occasionally search if there is any progress made on this obvious and elegant engineering solution. You've actually gone and done it, by yourself and turned it up with carbon tubing, Legend!
Yes, coming soon. I did a complete re-design, mainly to use "standard" commercially available tubbing sizes. But then I realized I had a sizing issue and had to pretty much start all over again. Should be ready to release soon
@@designbydave Wow I wasn't expecting such a quick response! that's really cool. Did I miss it or have you not said what this build might cost? Also just saw your hang gliding videos ( I am only a H2) they looked amazing and I am so jealous.
Your videos really fired un my imagination! Since I have a conventionnai prusa 3D Printer, I was thinking of printing with a more common plastic and then wrapping the parts with carbon fiber. From your enginneering standpoint, if you have any thoughts about that solution I would be more than happy to read them! Also I was juggling with the possible added benefits of using square tubing instead of round ones, especially for the top and down tubes... Many thanks for your videos!
Thanks, I'm super glad to be able to inspire others! You can print this material with your printer, you just need to get an insulated enclosure for it. The construction method you describe certainly sounds feasible. I would probably plan to make a few practice parts to ensure the resin used will bond sufficiently to the 3d printed parts. Might need to experiment a bit there. Best of luck.
Square tubbing, I would assume, to be more torsionally stiff, but I'm not sure you need that. Also, I assume square tubbing will be more difficult to source then round (but I haven't really looked)
I am impressed 🥳🥳🥳 I usually never comment but this is amazing Keep going great work You deserve it 👌👍🏼 Find it good that you respond to your subscribers
This lugs style 3d printed bike once reminded me on colorfabb's design Do you consider deep detail on bike geometry measurement?? Because that was my problem if i want to build my own bike
Yes, the Colorfab design on Thingiverse was the inspiration for this. What do you mean by "deep detail on bike geometry measurement"? The basic dimensions are based off of a commercially available, commuter type bike.
www.thingiverse.com/thing:5138980/files I put it up but realized I have some geometry issues and decided to start over with the design again. Plus, Thingiverse is having issues, so I'll pull that down and replace it with the fixed one when I'm finished. This, for now, can give you some idea of what's involved.

Build a mountain bike so you can take it to failure, well to film and research and development. Find the weekness'es in the frame. My question is why haven't the manufacturers used that technique. I'm glad they haven't i like my smooth frame design. But i can also see the benefits of this bike especially if i could replace damaged parts of the frame. Well interesting to say the least.
Just amazing! Who dosen't want to build their own carbon bike. I can imagine a kit ready to go. Thanks for the great videos.
Yeah I was thinking something similar. Buy a kit that includes the tubes, hardware and STL filed necessary. Then get to printing.

There are a number of small companies that have been doing it for a while now. Bastion Cycles for example.
Really neat. Just proves that people can design and make for themselves things that they hadn't though possible before.
This is awesome. I want to print a bike, and seeing one working like this is inspiring
Thanks for checking it out!
I can’t wait for the open source release! You’re amazing!

@@dalekslayer777 there is a bill of materials shown in one of my videos.

I've done this before with bamboo instead of carbon tubes, it worked pretty well.
Great project, awesome work 👏 will love to see files available for a build and maybe a gathering of 3DCB!
Thanks. I'll try to have the small size up in the next few days.

I kind of want to build a trail bike like this but use steel lugs. Nice work BTW!
I am impressed 🥳🥳🥳
I usually never comment but this is amazing
Keep going great work
You deserve it 👌👍🏼

@@designbydave ah so you just use geometry from other bike ?? I thought you make custom geometry for your body
@@dhupee That is correct. Need to start simple and use a geometry that I know works.
do you have recomendation for good resource of such geometry
thanks by the way for responding
@@dhupee I copied the main dimensions from this bike - lemond.com/prolog
I’ll give it a try with my Ender 5 plus the second I can get my hands on the files

what a great project! do you know the aprox. weight of the frame? Which fork did you use? many thanks
Frame is 3.75 lbs
Fork is a cheap generic fork from aliexpress
@@designbydave thanks thousand times! I'll definitely try this project once I'm finished with my other duties. Genius idea ..
hello. What is the weight of the frame of such a bike?
I think it was 1200-1500 grams. Final bike weight was around 19 pounds
@@designbydave wow that's a pretty cool result👍
How heavy is the bike ?
Also what 3d printer did you use ??
And filament type
19 pounds

This is not how you perform structural load testing. Thanks for checking out the video
Change your name to Davide and use more words like "passion" and "artisan" and you'll get rich off of this frame building business
Haha, perfect!
