    [That's an interesting idea. There is a system that uses stainless steel powder to make "green" forms which are later sintered in a kiln and infused with bronze to produce solid metal objects:...

    Have you ruled out a non-feeding line? If an air bubble has formed in the tube, it can often prevent the binder from flowing. There could also be an issue with the printhead; sometimes the output...

    I've never heard that before. What is stereoscopic viewing supposed to do to them? My mother said that when she was a kid, she was forced to view stereo slides by doctors, who prescribed it to...

    It sounds interesting, but difficult to work with. The differential shrinkage (much more in Z than X and Y) means parts will seriously distort on firing. I suppose one can learn to compensate by...

  6. I wanted to use them for making art pieces,...

    I wanted to use them for making art pieces, primarily. And I'm a DIY kinda guy, so it seemed like I'd have better control and save money by keeping it in-house. But getting them to work and keeping...

    If you're really going for high levels of detail, I doubt that you'll be happy with the results of FDM printing. By its nature, it will have fine grooves over the whole surface where the individual...

    While there are sites that have models you can buy (or even download for free) this seems unlikely to be available. But if you make a model like that, there are plenty of places you could upload it,...

    You could try an incubator heater; they keep things warm but not hot: http://incubatorwarehouse.com/48-watt-incukit-dc.html

    Anything can be compared to anything - apples can be compared to oranges. But that doesn't mean they're the same. SLS nylon 12 parts printed by the Fuse1 are rated at up to 52MPa for tensile...

    And funding it yourselves? How's it going? Are you running into any problems with stopping the flow, or entraining air? Has someone already patented the idea of a pellet-fed printer, so they can...

    I don't usually believe in anything that launches on Kickstarter, but Gigabot actually knows how to...

    Ask Davo; his Hyrel printers can print in clay or similar substances. You can probably adapt any printer to do it, using a paste extruder instead of a heated one that relies on plastic filament....

    Drawing, as in accurately reproducing a 3D scene in 2D by hand, is a nice skill to have, but it's not essential to 3D modeling. There are many ways to produce a model; you can scan something and...

    Delta printers are fun to watch when they are working, but they are a huge pain to deal with when they aren't. Since no single axial move happens on a single axis, but requires a combination of...

    Mostly I use Chrome. But I think you're right - when I used Firefox just now, I didn't notice the problem.

    Do these parts have to be 3D printed? It sounds like something that would be better done with CNC machining in a transparent material, a process that's better suited to the sort of precision you're...

    It might not be locating the Z zero point accurately. Have you calibrated that so the nozzle is almost but not quite touching the bed? Also, many print beds need a little help with adhesion. Some use...

    You're going to have to take it apart anyway to replace the bearings, so wait until you do that before ordering the new ones. A different length won't matter much, as Traykan says, but a different OD...

    Does this large CNC router really run entirely on unsupported shafts? That's not recommended over long spans. Do you have a way to press out the old bushings and press in new ones? If it were me...
