Re: Gluesticks as FDM-material - 16 years ago

Probably EVA, + additives, according to Vik's original mecano RepStrap used a hot glue gun, btw. I imagine the glue gun you end up using isn't designed to run for hours and hours. I'm curious what failure mode you'll get.

Done. You may want to contact the fellow trying to start the South Africa dorkbot group: Along with the cape town fab lab: I normally try to point folk at a local robot hobbyist club, but .za doesn't seem to have one. However, the builder/developer of the huge-size free-plans CNC router is based in Cape Town: I would suggest you give him a call, he may be interested in doing up some parts

Re: Changes that need to be made to the extruder - 16 years ago

Far easier to put down a paste of aluminum-powder and some liquid or wax like binder an then and sinter the whole object in a furnace. Regarding laser-sintering of metallic powders, I believe the metal particles are coated in some kind of laser-susceptor (absorber, so that the metal heats up) or a flux perhaps, to prevent oxidation (low speed or 'my god, the printer is on fire'). I don't think

Re: Changes that need to be made to the extruder - 16 years ago

Won't aluminum will erode the nozzle, regardless of the material? Probably more efficient to do lost wax casting. Maybe you should consider building it up like MIG welding? or this stuff: They're all a bit beyond us right now.

SCAM Warning/Disclaimer - 16 years ago

SCAM WARNING We've had a few attempted scams If you receive a Private Message or Email from people claiming to sell RepRap parts, be careful. 1) Don't send money to random people. 2) Do a quick google search. If they have a history of posts and have established them in RepRap forum, then it is probably safe. 3) No history? -> Unsafe. 4) A Money Order to another country? -> Unsafe. 5)

"Kiosk", by Bruce Sterling - 16 years ago

THE FABRIKATOR WAS UGLY, noisy, a fire hazard, and it smelled. Borislav got it for the kids in the neighborhood. One snowy morning, in his work gloves, long coat, and fur hat, he loudly power-sawed through the wall of his kiosk. He duct-taped and stapled the fabrikator into place. ... via boingboing.net, I think.

Re: Proposal: International RepRap Hackathon in Houston or New Orleans - Memorial Weekend - 16 years ago

I've been planning on heading out for Maker Faire Bay Area 2008 (May 3-4 - official dates, plus 1-2 days setup) We can just as easily do actual work there as dog-and-pony stuff. (This is not to say an earlier date somewhere else isn't a bad idea, only that I've already got Maker Faire penned in my datebook/budget.)
