Eventorbot! Open source 3D printer. Simple with less materials. Frame is made of a single 4′ long, 2 1/2″ square tube (16 gauge/1.5mm/.0598″ thick, cost: less then $20.00). With the design there is less plastic parts, stronger structure, all wires are hidden, and a more appealing/finish look. (…)

The unit is supposed to resemble a robotic arm with hydraulic tubes. It was designed for prints to be less affected by vibrations. With the 1 solid frame, any vibrations of any axis will cause the other axis to move with it. For example: If the X axis causes a slight vibration/1mm movement to the right, the Z and Y axis will also move that 1mm to the right. This will result in a better print as everything will remain squared.

The Thingiverse page (linked to above) has all the STLs you need to print your own, supplemented by the usual hardware — look for the parts list on RepRap.org.

Its an amazing cool and solid 3D Printer. I also like this PopFab device which allows you to change the toolhead: http://www.smartlab.at/popfab-the-portable-fabrication-multitool/

And yet another cool 3D printer that I either can’t fabricate myself or can’t afford to buy ~.~

Also its really cool that 3D printers are printing more of their own parts but….. its getting to be a bit “chicken & egg” you essentially need a 3D printer to print the parts you need for a 3D printer. Once the technology becomes sufficiently ubiquitous it won’t be that big a problem but as it stands now ~.~

  I completely agree, It’s almost as if you need to find a large group of friends to go in and purchase a 3D printer and then print off the parts to build more. The problem is finding that many friends willing to put in the money, time and work for a 3D printer.

  Then there’s the old way… make imprecise parts by hand and produce a machine capable of making precise parts. I’m considering taking the sketchup files for dimensions and using a high quality plywood to make the parts as best I can or as best as they need to be using available tools. Early lathes were made this way. The Gingery Lathe is a hand cast rudimentary lathe that once made can turn high precision parts. I would think the same degrees of separation of refinement possible here.

  From: Duy, founder of Eventorbot.
  For those who do not have access to a 3D printer. I have had experience making molds
  and using urethane plastic. I will try to make molds of the plastic parts and mold it with urethane plastic. This plastic is very rigid and durable, and is equal or better then ABS.

  Jerry, this is the route to go. I got a gen6 electronics for 100 bucks and all of my motors for free from old printers from the local e-waste place. I am just finishing up my frame which is made out of mdf that i already had so $100 is all i’ve spent

  Jerry, I think I’m taking your advice. I’ve broken down the Sketch Up drawing, but I’m having my Drafting Students dimension the parts. Some of them will be hard to recreate perfectly, but hopefully I can get them close enough..

I know this was just a test print, but here’s a suggestion for future videos: if you are going to show a tool make something how about showing us the result of the otherwise BORING video. Yeah, 3D printers are way cool BECAUSE THEY MAKE STUFF – not b/c we can watch the print head moving back and forth for 5 minutes. This is like doing a conventional color printer demo and not showing us the sharp image and vibrant colors it can produce.

Sheeesh! You’d think smart people would know better.
