I mean, if you want to make a mounting bracket for a switch, it might be able to hold that, but what's the stress limit on the plastic? That being said, I've been watching the cupcake 3D printer into and I think it's pretty cool and a very interesting idea. I'm looking forward to seeing your progress and hearing about how it's going.

It's the same stuff Legos are made out of. As far as how much stress it could take, it all depends on how the part is designed and how the force is applied. After all, those little plastic bits that hold up shelves can take quite a bit of weight. The samples I've seen were pretty solid.

I had been looking at MakerBot Industries Cupcake CNC, but decided that it would be more interesting to build the RepRap Mendel. For starters it's a less expensive option, and secondly it can print larger items than the Cupcake CNC. There are also projects in the works to expand it's capabilities, which seems pretty cool as well. http://objects.reprap.org/wiki/RepRap_Version_II_Mendel What's cool about this, is that the printer can print a lot of it's own parts. Of course that means you need to know someone with a 3D printer, in order the print up the parts to make your own. Fortunately, a friend of mine recently purchased one of the Cupcake CNC machines, so that step is soon to be taken care of. So what do you do with your very own desktop 3D printer. Well print "things". If I need a plastic bracket for something, it's a simple matter of opening up your CAD software of choice, such as Solidworks or Google SketchUp, design your part, and then print it. Or you could simply download the design that someone else made and print that. There is a whole bunch of stuff over at Thingiverse, which is an open source repository for stuff people have created. I already received the first batch of parts for the machine, and I'll be posting a more detailed account of my progress over on the DorkbotLV web site. I saw this yesterday, fucking awesome. Its a touch out of my "toy" price range at $520+ but the fact that this is now desktop portable means that its only a matter of time til one will be mine... oh yes, it will be mine Caliber and I would shoot the shit about our kids, patriotism, military stuff, and the merits of plentiful parking in "rogue states." --formatc |
