Re: Selective Thermal Sintering using DLP and instense, non-laser light source - 15 years ago
Quoting myself from the Generational Degradation thread: "In addition to removing the horizontal movement axes by illuminating the entire layer at once, your idea also might remove the vertical movement axis. One could simply refocus the projector for each layer. The lens is moving up and down, of course, but the entire projector wouldn't need to be moved.

Re: Why print plastic when you could print liquid glass? - 15 years ago
You're right. P and N are types of semiconductor, not types of transistor, aren't they? I thought you were talking about the glass itself being the transistor, not just a substrate, for a second there. I'm sure the nanoscale-layered printed glass would make a great substrate for organic semiconductors, if a tad time-consuming. Who knows? Maybe economical home printing of electronics will be widesby fgrams - General
Re: Generational Degradation - 15 years ago
That makes sense. Tools are used to make tools, and all that. I suppose quality would even get better over time with design improvements and all that. Thanks!by fgrams - General
Re: Why print plastic when you could print liquid glass? - 15 years ago
If I recall correctly, transistors (what I think you meant with "semiconductors") are printed on silicon crystal wafers, a semiconductor material. Glass is made of silica (SiO2) not silicon, so you wouldn't be able to print transistors on it. Using liquid glass is a cool idea, but printing something with nanoscale layers, like the Physorg article mentioned, would take forever, lol! It would be nby fgrams - General
