[QUOTE="TECHARTISAN, post: 41374, member: 1289"] Etec's machines use UHP (p-vip) lamps..their resins operate in the nearUV...capitalizing on the spike shown above around 405nm. The bulb inside the $1000-1500 proprietary replacement lamp housing can be extracted and replaced with the same model Osram p-vip for $80-150....if you dont mind getting your hands dirty....oh and probably voiding your Etec warranty :( Xenon flash lamps are used in their post cure, but like most xenon curing lamps the power density is much higher then what the actual DLP exposure unit produces. Consequentially, most of your traditional UV cure materials just dont work. The build limitation of the etec's single material build eventually soured me on the whole concept...most of my interest in 3d modelling and prototyping suffers unacceptably when support removal comes into play.... I still try to lend what support I can to the [URL="http://tech.groups.yahoo.com/group/diy_3d_printing_and_fabrication/messages"]hobbyists trying to replicate Etec on a budget[/URL], [URL="http://3dhomemade.blogspot.com/2010_10_01_archive.html"]there has been one sucessful replica,[/URL] whose creator has been teasing the hobby community with an "open source" gone "closed source seeking a patent and big profits" for nearly a year now. My own interest has shifted towards multijet modelling, having become quite enamored with the InvisionHR I helped my former boss acquire from you a few years ago, Ive been working on a xerox hack for half a year already and expect to be at it at least another 12 months before I get the results Im hoping for....but thats a matter for a different forum entirely :) [/QUOTE]
