RepRap: Blog

Mendel comes in at £395 for the lot (in the UK).

Assumptions are:

- Using RS (UK) for bought in standard stock (fasteners, bearings, bars, studding and belts)
- 4 off NEMA 17s, @ £20 each
- RP parts @ material cost of £20 (assumes no commission)
- Thick sheet cost (inc cutting cost) @ £20
- Electronics are Zach’s Gen3 @ £110

Raw data can be found in the Mendel assembly data sheet on the wiki. A tabular summary is also available on the wiki.

Here’s a graphical breakdown:

I'm off to CStem 2008 in Turin, who've kindly invited me to speak on RepRap. If you're in those parts next week, drop in!

They also wanted me to bring a working RepRap Darwin to demonstrate. What followed says something interesting about the cost of rapid prototyping. We looked into the amount we'd have to pay to transport the machine from Bath to Turin (it's not too heavy, but is bulky and delicate). It turned out to be both more expensive and more troublesome to do that than to buy and ship a RepRap electronics kit from the RRRF and a Bits From Bytes Silver RepStrap kit to Turin direct. So that's what we did. The CStem people have built and tested the electronics already, and are putting the laser-cut kit together as I type. When I arrive I'll help them with the last stages.

Mark you, last week we bought a whole working lathe for my University lab that cost less than a single RP polymer cartridge from a well-known RP machine manufacturer. How fortunate that it is possible to build all the RP parts of a RepRap machine from two such cartridges and still have quite a bit left...
