 In a pursuit to get a low cost RP system for home use, it would appear that a concept along the lines of the folloowing might be a faster approach than some of those discussed under this topic.Concept:Start with a Xerox 8400 solid ink printer which has a resolution of 600 dpi and a layer speed of up to 10 layers per minute. The price of this basic engine is $1000. Using this basic engine, modify the printer to accomodate a Z axis. Estimated cost is less than $2000. This could result in a 3D RP system for less than $3000.Combined with development of slicing software, this could be the basis for a very useful thesis project.The resulting system could make very fine geometry masters for jewelry and medical applications.Do we have any takers?Joe --- On Sat 03/26, wrote:From: [mailto: EdGrenda@aol.com]To: A.Bowyer@bath.ac.uk, eitan@biomodel.com Cc: rp-ml@rapid.lpt.fiDate: Sat, 26 Mar 2005 11:27:13 ESTSubject: Re: [rp-ml] New machines could turn homes into small factories (My 2 cents..)]In a message d

Floreat emptor! Yours Adrian http://staff.bath.ac.uk/ensab >>Hi Adrian:Something very close has been done. Neil Hopkinson and Poonjolai Erasenthiran at Loughborough Univ have used carbon-blacked nylon for an object material, and white nylon powder for support in a technique they call High Speed Sintering. They envision selectively jetting the black stuff, or jetting an energy aborber on the surface of the stack as you describe - among other implementations. Already has a UK patent and I'm guesing a search would turn up additional prior art. See thi
