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.

  • The electronics are (relatively) inexpensive. The bulk of the cost is in the mechanics. Google 'ballscrew' and check the prices. Note that you'll need three of them, plus motors. This cost is high (approaching $500 for something that may be a toy at best, unless you spend another $500 or so).

    Acme screws are much cheaper... about 50 bucks for a 6 foot length... cut that in half and you have enough for your vertical axis... the horizontal axis on the other hand can be belt driven like any other printer... although there are diffrent challenges depending on who you are and what you have acess to .. some people may have a hard time with the task of the mechanical portion... others will have issues with the electronics...

     

    im actually building a 3d printer out of 3 or 4 old Hp g85 office jetsBuilding a 3D printer out of Hp G85 Office jet printers

    if your interested in seeing my progress i will be posting it there

     

    Edit:

     

    most printers are belt driven so you can get  your belts from them and they also have the pullys that fit them...  you just need to make sure you have matching steppers for each drive!
