I was at one point considering a RepRap-like project using just a slip printer and discovered that NASA had built one. They were inkjetting ceramic parts onto a hotplate. As they built up each layer, it dried due to the heat from below. They could graduate the material through the part, moving from a ceramic, through a creamic/metal composite to pure sintered metal at the other end.<BR/><BR/>Vik :v)Vik Olliverhttp://www.blogger.com/profile/08344580890636084746noreply@blogger.comtag:blogger.com,1999:blog-12223283.post-1120248460105826932005-07-01T21:07:40.106+01:002005-07-01T21:07:40.106+01:00Not too different to depositing icing either. Just not so tasty :)<BR/><BR/>Vik :v)Vik Olliverhttp://www.blogger.com/profile/08344580890636084746noreply@blogger.comtag:blogger.com,1999:blog-12223283.post-1120221828081899732005-07-01T13:43:48.080+01:002005-07-01T13:43:48.080+01:00If you want to get really hot, you have to go for ceramics, I think. Of course if you have wax (or any low melting point stuff) you've immediately got investment casting in the bag. But an RP machine that could directly deposit ceramic slip; there's an idea...Adrian Bowyerhttp://www.blogger.com/profile/17595509188999219420noreply@blogger.comtag:blogger.com,1999:blog-12223283.post-1120061068369691302005-06-29T17:04:28.370+01:002005-06-29T17:04:28.370+01:00Exceedingly nifty - looks like it's getting close :)<BR/><BR/>Now if I can just arrange to get materials to start mine, and learn the neccesary electronics...<BR/>*Sigh*.<BR/><BR/>Also, just a thought (and I think it's been brought up before), but it really would be nifty if it were possible to make a part out of either something that can stand high temperatures (read: incandescent), at least for a short period of time, or something that is easy to melt out of such of a material (say, wax and plaster of paris). Melting most metals is surprisingly easy to do, assuming the presence of some form of blowing device and charcoal, and casting is a wonderful thing :)...<BR/>So easy, in fact, that it's more of a challenge to avoid pulling a white-hot sparkler of burning steel out of a forge than it is to get it hot enough to work it.jonoredhttp://www.blogger.com/profile/01769864294142089196noreply@blogger.comtag:blogger.com,1999:blog-12223283.post-1119944041637012142005-06-28T08:34:01.636+01:002005-06-28T08:34:01.636+01:00looks great!
