Robots 3D Print a Stainless Steel Bicycle Designed by Students from TU Delft
Well, you certainly can't hide a motor in that.
Certainly not!
Thank you for the information you have provided , this very helpful
An interesting student project but it seems to be one of those that fall under the category of "I wonder if we can..?" which does not always mean we should.
Yes you are absolutely right. Our goal was simply to investigate if it is possible to make a functioning bicycle frame with this new method of metal printing (which is in development and optimization of print quality is ongoing).
A pointless project in my opinion. Whats the goal of this project? The advantage of 3D printing in metal is to manufacture designs that are complex and organic for a purpose. The purpose for an optimized design to achieve weight gains and significant strength. There is no point over designing and engineering something just to follow the fad.
More over, welding is an archaic process and a waste of material. It creates discontinuity and complicates the surface more than it needs to be. I ll be honest, it doesn't even appeal to the eye.
Read this to know more about an application of 3D printing in bicycle industry that has achieved a realistic goal.

Haha you obviously have strong opinions which I am glad you have shared! This project was primarily a research project into 3D printing with welding specifically and how that process could be applied. This type of metal printing is currently being developed but is already much faster and cheaper than laser sintering (the production method for project you included). It has its advantages and its disadvantages like all 3D printing methods. For us, it was also important that it did not look like a regular bicycle frame. Some people such as yourself choose to only view the project in the context of bicycle design which is very close minded. You should have another read through the article and not just look at the pictures.
