- Building my own bike frame is something that I've wanted to do for some time now, so let's get to it!

Sick, looking forward to this project :D
The geo and shape are actually perfect imo looks like a versatile design 👍
Thanks! Yes it has worked out great so far
too cool!
Thanks Dave, brilliant stuff. 45 years riding and racing and your "stuff" of as good as anything I've seen.
More please:)
Thanks for checking it out John!
this is some good stuff!!!
Thanks
I hit the like button when I saw the pause for cat time !
Cats are great
Nice work, Dave. Really looking forward to the video of you riding it!
Thanks guy! I'm really looking forward to riding it. Every time I have to run to the store real quick, or want my afternoon ice coffee, I'm like, damn I wish I had that bike!
Wow this is AMAZING WO AGAIN!!!
Thanks!
I enjoy following your videos, Dave. Interesting application for the 3D printed parts. I am eager to see the results. It looks like you take into account the Z-layering. This is a crazy cool project!
Thanks for checking it out. There's a term not many are likely familiar with, "design for manufacturability" That of course means taking into account the manufacturing method when designing parts. Since I know these parts will be 3D printed, I need to take into account all the capabilities and limitations of my printer. Hence that large, flat bottom surfaces, z layer orientation etc. Were these parts to be CNC machined or molded carbon fiber, they would look quite different.
@@designbydave - nice! I really look forward to seeing how this works out. I personally thought about putting in aluminum sleeves inside the 3D printed brackets then annealing them. This is a really neat bike project. It kind of reminds me Land Shark bicycles. Very unique and I think you are onto something!
This is awesome! Great job Dave!
Thanks for checking it out brother! More to come
Can't wait to see the final result!
I’ve been thinking about this too!! Glad I found your video have you thought about wrapping the lugs and other high stress points with carbon fiber and resin? With a big enough plastic bag and a vacuum pump you can pretty clean results
Wrapping the lugs with additional composite material is unnecessary unless maybe if you use a "regular" FDM material like ABS.
Hi Dave, amazing work, super inspirational! Im in the process of designing my own e-bike and plan on taking a similar approach. Do you have any experience with Rhino 3D or is moving to Solid works a better idea for prototyping/printing parts for a bike?
I don't have any experience with Rhino. From what I understand, Rhino is superior for surface modeling but does not have the same level of detail working with multi bodies and assemblies like Solidworks does.
When you complete this project could you pleeeease make it open source? Posting all the parts and the assembly would be amazing.
Yes. Working on it! Release soon.
This is sick! I'm thinking about doing something similar, but with molds of the printed parts, so I can cast em and make em strong enough for a MTB. Where do you get the carbon tubes, and how much where they?
Ebay. About $20-60 per tube depending on size
Hi Dave, I always wondered is there any possible way to do the load simulations on 3d printed parts through software programs as the manufacturing process is completely different compared to the traditional way of manufacturing.
As far as I know, there is not any commercially available simulation software that can do this. I was able to find a technical paper that outlined a numerical solution method for this, but it would take some work to be useful.
I would love to try this to make a stationary road bike for Zwift.
That would be sweet.
*Great **Latest.Bike** , good looking, good suspension and love the gearing. I've tested some bikes that were more then twice the price but not as good. Get lots of looks when riding.*
nice, are you going to wrap the 3d printed joints in carbon fiber next? I suggest polyolefin tape over carbon tow if you do, and a heat gun set lower than the melt point of the printed plastic.
No need to over wrap the 3D printed parts with additional material, but thanks for the tip!
@@designbydave really so just the printed parts are holding up ok? Thats awesome!
@@blueridgedsia I have over 100 miles total on the bike. Yep it's good.
Great work, David. It inspires me to work on a frame but I am concerned about a response comment. The weight of 3.75 pounds seems pretty decent but you said that a "conventionally welded Ti or Al frame would be less." I have a bike I love that is a recumbent called a Maxarya 2X. But it is too heavy, even though it is aluminum. If you looked at the frame, would say that changing to a similarly shaped carbon fiber lug and tube would not result in weight savings? I would love your opinion.
No weight savings with this construction technique. The lower strength 3D printed components requires more material (more mass) for equivalent strength.
@@designbydave What about using thin, flimsy connector pieces just to hold the tubing in position and then lapping them in carbon fiber?
Good process. I tried this approach and was using Fusion 360 and got frustrated and didn't invest the time you did in the model to make it work. I went back to my scuplture approach with pink foam and carbon fiber sleeving. Cool to see you do it.
Part of the reason for taking on this project was to learn and practice surface modeling.
Heavy relative to a regular carbon fiber frame?
Almost twice as heavy as the latest generation of lightweight frames
Brilliant idea but I might use the 3d printed parts for Carbon Mold making.
Because a 3d printed part will be never stable as a Carbon Duroplast.
Next challenge, you should 3D print your hang glider ;-)
I'll get on it! ; )
Hello Dave is the 3D model available to download? Thanks
Yes. See my web site designbydave.net
cover the joints with a layer of carbon fiber
How much has this cost?
It's been a while but I think somewhere around $2000 for the whole build
What printer do you use?
My modded Creality Ender-6. See th-cam.com/video/pIm2zar_TQ4/w-d-xo.html
and th-cam.com/video/6PIEF9uWKSA/w-d-xo.html
Щикарно!
I thought the carbon fiber filament was FAR more brittle than normal filament ?
Define "normal" filament. There are also a large variety of carbon fiber reinforced filaments so the ductility will vary greatly. This particular material I'm using (carbon fiber polycarbonate) is not brittle at all.
What size wheel fits the frame?
Probably about 5'3" to 5'7"
@@designbydave i have 700x32c, and I make small frame, it is ok? 🙂
@@bokaimre1578 i think so yeah
i watched the whole video to watch the car part
what was the weight?
Final bike weight is 19lbs
👏🏻👏🏻👏🏻 I want to make a e-scooter frame from abs plastic. See soon on my channel
Sounds fun. I also considered a scooter project at one point but never got much past the thinking part.

Hope that you are still alive
Yes alive and well and regularly riding this bicycle
Assalamualaikum
Where's the part where you mold and print in forged carbon also the joints? Cause don't tell me your goal was actually to make a carbon tubes bike with pvc joints.
Yes, watch the rest of the series
@@designbydave I've seen it! Cool I thought you were going to cast the chopped tow fibre to mold those joints. What if also... If the tubes had to fit the joints outside? I mean bonding the pipe, the inner part, with the exterior of the joints. They did like that in the 80s I heard (alluminium joints with carbon tubes). You might have to design a step on the joint and measure carefully the... oh lord. The beefiness of the pipe how's calld it, to make the depth of the step where you bond 'em.
I see the pro that you'll have straight cuts on the pipes, and you can size any bike to the rider cutting pitagoric correspondant measures for the 3 main tubings.
Send'em a very basic jig in the box and voilà, it's a DIY cut-to-size carbon bike! :)
3D printing is not work !
I use 3D printing a lot at work
