  Well, you certainly can't hide a motor in that.

  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.

  
  

  A bicycle is one of those products that is so hard to deviate from the 'norm', because the norm is based on such efficient and basic engineering principles. If you are going to step outside the box, then, really, composites are the answer for so many different reasons.

  
  

  This just seems to to take the welding part of an existing process and takes it further than it really should go, with seemingly little if any benefit and without even the aesthetics of a highly skilled welder.

  
  

  As far as "build on their research when designing 3D printed metal bicycles", again, nice at the student level but seeing how refined and efficient the current processes are, both for metals and composites (with and without the use of other 3D printed assets), it's hard to see something like this going anywhere beyond what this is.

    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).

    We have succeed in that goal. 

    
    

    Whether it is an efficient or practical method for producing bicycles is another discussion and one for future research given it has now been proven possible.

  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.
