You did wax-resist etching to make the metal compliant joint? Wow. I just figured that you had hand-carved each segment as a stand-in for punching it out with a steel tool. That's.... fascinating. How well does the aluminium compliant structure work in comparison to the acrylic or paper?by mycroftxxx - Look what I made!
Apparently some of the props in the movie were made on objet printers off of scans of the actor's hands.by mycroftxxx - Let's design something! (I've got an idea ...)

I know that people say that the high-power laser pointers are not powerful enough to use in laser-sintering, but I have been wondering about that. The powder used in powder-coating metals is fairly cheap and melts at about 200-250F. If these lasers can melt through electrical tape and ignite matches, shouldn't they be capable of transferring enough heat to a bed of black powder to melt it at thby mycroftxxx - Laser Cutter Working Group
If sodium alginate is left in contact with calcium chloride long enough in a water bath, it will solidify. I am not sure how strong or sturdy the resulting structure will be, though.by mycroftxxx - Plastic Extruder Working Group
So, the question would be whether anyone who is good at mechanics wants to figure out a delivery system for a thread of sodium alginate into a bed that is slowly being lowered into a dish of calcium chloride. It's a good shortcut to making a room-temperature fused deposition modeler.by mycroftxxx - Plastic Extruder Working Group
If I can direct your attention to for a moment, I am hoping someone here can figure out which company makes this material, and whether the material itself is protected by patents or other burdens. In short, the stuff is a salt-water hardening polymer that glows in the dark. While the glowing function isn't that interesting, the viscosity change is. If the material is easy to produce or procurby mycroftxxx - Plastic Extruder Working Group

No, no blogging yet. I guess we'll have to start one. And do some photography. So far, there isn't much to see. Materials consist of a cardboard box containing parts from a Dell 720 and a scanner. Otherwise, most of the work has been done on pen and paper or in folk's heads. We will start assembly of some of the parts as soon as we get the arduino and motor control shield in.by mycroftxxx - Powder Printing and Selective Laser Sintering
Wow, it's nice watching this thread continue to mature. My hobbyist 3d printer project is slowly getting off the ground, and a _very_ rudimentary wiki is taking shape at . Some of the data there is outdated (like the laptop giveaways, alas), but there is already a small core of builders coming together for coding and mechanical design of a prototype. Other contributers are welcome, though therby mycroftxxx - Powder Printing and Selective Laser Sintering
I would be interested in attending or hosting a meeting. I am working on a non-reprap 3d printer and would like some feedback from people with more skill. I live in the Medical Center area, in a large house with multiple roommates who would be interested. I work weekdays, so either weekday evenings or weekends would be good for me if there's interest. If you guys want a meeting, I can run itby mycroftxxx - Texas, Houston RepRap User Group
I am in the process of doing initial writing for a community-oriented project for a Z-Corp style 3D printer based on the work of Graham Stabler (the indoorflyer.co.uk guy). I have been exchanging emails with him on the design on his parasitic printer controller for the print-table and current plans involve getting mostly-universal coding together for the Arduino platform. I will be posting a smby mycroftxxx - Powder Printing and Selective Laser Sintering
