3D printing

Very cool. Wonder if anyone has used these yet in daily RC.

That's the printer I've got here. It works quite well (playing up at the moment though) and I've used it to print a fair few things for various people though for RC gear only some exhaust nozzles for an F22 that a guy on this forum is building.
FWIW it's Aus$0.60 per gram to get stuff made on my unit.

There are many folks using 3D printers for RC stuff but few have made flying planes except for these guys:

There is one guy here on rc groups making nice little custom edf housings and parts for micro jets. You can also check out my blog for more 3D printed awesomeness.

Anyone knows what the exact composition is that white powder? For high performance crafts I don't think i would use 3d printing but to help make it, most likely. Would 3d printing work to create molds?

The Z-Corp powder is a plaster composite, not a plastic, so you would want thick walls and infiltrate with epoxy for added strength. It's one of the cheaper methods of 3D printer so not a bad place to start making molds if going down that route. You want to bake out the part before infiltrating to drive out moisture and stabilize to avoid warping.

Its not that strong and mainly used for prototypes.

Would be nice is there was a way to make the material stronger. Maybe
spray it with something to give it more strength. Epoxy spray etc. Wonder if anyone has done some testing with that.

Ive been thinking of buying a pretty large 3D printer and also a 4x8 CNC
flatbed table to cut foam wood etc. The 3D printer could be used to
make more complexed parts.

Who makes a large 3D printer?
Im also going to be looking for a great CNC 4x8 router table.

For more professional material printing, you may consider EOS System using AM methodology. It can print titanium and even carbon. You may hook up with their US distributor if interested to start a commercial venture.

I'm seriously considering sending my ribs/formers to shapeways for printing in this stuff. At about $0.75 per cu. cm, it's fairly cheap to just do this by mail. My thinking is I can fill the gaps, screeding to the formers to save on sanding. Yes it's quite brittle, though they infuse it with CA now for added strength. It has some clear benefits over stick-building plugs, especially in the precision area. Unless I come across a better sounding method, this is probably what I'll go with.

Figured i would share something new that i came across today on facebook. This company is 3d printing an rc extra 300 control surfaces and all. It looks good so far but only the video and final pics will tell. So i would expect it probably wont be too long that a company starts printing rc plane arfs.
