Just thought I'd mention that at the cheap end a "3D printer" in Kit form is now available for around £600 but it's only 3 colour (RGB plastic) and the res. is only 0.4mm. At the higher end of the scale check out Z-Corporation's Z650 (from a UK quote), "feature" res. 0.1mm: ********************* 1. New!

ZEdit Pro – Advanced File Preparation Software ($2500 value/seat) ********************* If going for accuracy/resolution rather than colour there was one (I think for over £200,000) being shown off at the Gadget Show event in Birmingham earlier this year - that was considerably higher in terms of "solid" resolution and could print a single object in varying colours but at the moment is restricted to around 10 grey-shades from black to white, plus transparent and a translucent yellow/amber. Of course the slight issue for general use of the Z650 is the following from the same quote as above: *************** ZScanner 700PX Hand Held 3D Laser Scanner, £ p.o.a. New!
