The RepRap challenge has a number of obstacles for the interim award. There are two in particular that seem insurmountable.
- Maintain a total materials and parts cost under $200 and that 90% of the volume of the printer parts be printed.
- The ability to print autonomously without a PC attached.
I have to imagine something large enough to accomplish all of the other goals would cost well over $200.00. If an entire Darwin or Mendel were trasmorgrified King Midas1 style into pure plastic, I would think the plastic alone would eat up 90% of the budget. Even the best deals around the internet for RepRap parts just the electronics are roughly $215.
I say it seems insurmountable – but if someone had told me two years ago I could one day buy a full kit for building a robot that would make me any plastic thing I could imagine for $1,000.00 I would have laughed at them.
