Rapid prototyping

[typhoon_driver]

I was shown this in a university lecture yesterday and couldn't believe how cheap it was!

$1500 for a rapid prototyping machine? Not long now till we get desktop printers for our robots

Re: Rapid prototyping

In antweights we already have

Andy Hibbard has created 3 robots from rapid prototyping, Anticide, Kwijebo and Cataclysm. Pics below:

Re: Rapid prototyping

I've had a frame printed for an AW but haven't finished to build it yet. Are these rapid robots strong enough?

Re: Rapid prototyping

They seem to be, although direct hits can break/snap off bits (as happened to Kwijebo at Richmond) but the advantage is that you can just order a new chassis and have everything slot back in from the old one

Andy says they're slightly weaker than polycarb bur have the advantage of being one piece as opposed to having joins.

Re: Rapid prototyping

Lol turns out that they are crap (not too surprising I suppose). My university actually has one along with a couple other rapid prototype machines. Got to get a good look at them today. One had produced a chain with no breaks that was able to work as a chain. Only made of an ABS type plastic but still very impressive.

Re: Rapid prototyping

Also see Makerbot for a £600 3D ABS printer.

I'll be up for getting one of these when they make the software/hardware interface less painful.

Re: Rapid prototyping

Didn't see this thread before, I rapid prototyped the hubs for my powertool drag racer years back at college, a few other people did there Iva projects using a rapid protoype machine also and droped there component while being clumsy. they shatter pretty bad. I'm sure I read somewere someone was developing a rapid prototype machine that could print titanium. That would be handy tool

Re: Rapid prototyping

I made the prototype for predator's disc on the one at our college dave, came out pretty good although james's dropped it and it cracked.
The one at our college was more like Plaster that added layers of epoxy between powder to built it up. Its actually pretty acurate, much more so than the plastic type that gary linked to. That just lays a thick slither of plastic ontop. The proper prototyping machined that activate a liquid with a laser are awesome, and i believe thats a similar method to the ones that can now do aluminium. I presume its a pretty terrible grade and quilities, although super nice for non stressed parts.
I loved the 3D scanner at college, scan an object, and print in in 3D

Re: Rapid prototyping

One of my mates graduated and got a job with Maclaren F1 racing. He told me that they recently purchased a titanium rapid prototyping machine for a good few million. The parts that come out of it are just short of being as strong as machined parts.

Incredible!

Re: Rapid prototyping

Maybe so Gary, but i dont class machines and tools used in F1 to be real - especially for use by us mere mortals lol

If it cant be bought for a few hundred ££ then its not worth looking at

Re: Rapid prototyping

Id love to see a video of a titanium printer working.. id only read about it before, i heard it was nasa working on a portable one for spair components in space or somthing crazy..

And yeah i remember james smashing that disc and gluing it back together lol. loads of people in my class at col smashed there work up by mistake

The ones me and grant used were expensive enough at over 40k for one that couldnt print anything much bigger then the size of an A4 piece of paper. Well acurate though.
