Challenge - chap 3D printer

tada9

Hi Ben,

I have a chalange for you.

Try to build the cheapest possible 3D printer by hand with no use of CNC or 3D printer.

It should be based on Raspberry PI(another chalange?) becouse it is cheaper than Arduino.

    I would never discourage any ONE person or group from building anything that they could imagine! Whether this thing be failure or not? As I look back on my 6 decades past...I've been many times over on failure than success! Although retired via permanent and restrictive infirmities;I still manage my share of scrounging and dumpster diving! I've built my machine shop many times over,each time improving and refining the accuracy of each machine. they may not be the finest machines ever built,but I know how each one works and how to fix or fabricate a replacement part!

     

    When people learn to do things for themselves-by themselves,they will learn forever. Chris,I appreciate what you have shown us in the past. Element 14 is truly a community where the exchange of products,design,learning and free discourse of information can be passed to all that seek  it!  My time on the soapbox has run into overtime;I yield.

    I agree, sorry if I sound like if I was discouraging him, not my intent... I'm new to the element14 community, I've only been reading and looking at this community less than a year.. I actually built my first 3d printer last winter, and tried building a second one printing parts with the first one, 'till it stopped working...(bigger print surface, and as you said looking for better quality/resolution in the prints.

  • Because this thread has unanimously concluded that "It cannot be done", I've kicked off a different discussion in a new direction that has the potential to deliver that goal and a very lot more, over in the 3D Printing group:

     

    Closed-loop control for-low cost 3D printers

     

    It's the future anyway, since open-loop positioning just can't deliver huge increases in accuracy, especially at low cost.

    Pretty sure no-one said it couldn't be done, I know I said above "We are not saying it is not possible". Just saying that if you do a cost-benefit analysis of using recycled parts you probably won't come out as far ahead as people think they will. I've had some discussions about closed-loop control, none here on E-14. I used to do that on an industrial level. I've got a few feedback designs I've been working on but haven't gone anywhere with them. Will check out your new thread.

    Agreed.  Recycled parts get you only so far, and that's not very far.  I would highly encourage component reuse when it meets the desired operational specs for a one-off job, but I would never encourage sticking to old ideas just because we have old components for them.

     

    Civilization advances only as it devises and embraces new ideas.  Open-loop FFF printing is now an established idea.  It's an awesome foundation and it's empowering a whole new generation of people, but it's not the endpoint of where we are heading, and it can now be used as a launchpad for new and more powerful ideas.

    Hi Shabaz,

     

    I have almost completed constructing the mechanical parts of 3 D printer. But I need a lot of guidance, maybe you or  somebody can spare some time to help me understand all the parts of 3 D printers.

     

    Is there a way I can upload the image so that the LEARNED professionals at Element14 can see the product and guide me to improve the product?
