A new Instructables describes how one maker designed and built a working 3D printer using, well, junk.
Instructables user Gelstronic set a goal of making a sub-100 Euro 3D printer having these characteristics:
- Fused deposition modeling ABS/PLA
- Heat bed
- Use of open source firmware, modified version of Tonokip
- Free host software, Repetier-Host
- Max. build size 40 x 40 x 40mm
- Resolution 0.08mm
And he succeeded. While the majority of the components were salvaged or were simply lying around in his (and your) workshop, a few items were purchased. But according to our primitive arithmetic, Gelstronic spent less than 50 Euros (USD$68). The resulting machine is a bit primitive, but what else would you expect?
Unfortunately, the instructions are a bit vague and are only usable by experienced machine-makers. But the point has been made: anyone can build a 3D printer out of junk. Even you.
