One of today's earlier posts mentioned the Solidoodle 3D printer.
I'm sure some of you have the big machines at your job but this thing for $500 looks really interesting. Then I was thinking, it's neat, but what could you do with it. Found this

That's pretty cool. I think i'll stick to the old fashioned way, though - I like making chips!

Chips are good. I love chips.
Given that the thinnest slice it can deposit is 0.1mm (.0039) other than a pretty forgiving wobbler I'm wondering how complex an engine could be built with it.

Stan, I'm building a RepRap. reprap.org And although the little wobbler will probably be printed ::) the main idea is to use it to print patterns for sand-casting. Much easier than working with dead trees. ;D

Cheers

The last time I did casting was opening day of trout season :D
Have you figured what the reprap will cost by the time it's printing.
Also, what is the max size it can print

Thanks
Stan

Let us know how that goes - I've got an UP! 3D printer and it does some pretty nice prints.

I'm about 90% done at the moment and don't have the numbers crunched yet but I'm figuring it will be in the $400 range. The print bed is 8.875" square with a z axis of about 4". I haven't loaded the firmware and run the motors yet to test the actual extruder extents, but I'm guessing 7.5" - 8" square by just short of 4" high. Should be large enough for 99% of the parts I cast if I can get the surface finish acceptable (primer, filler, etc.). As you can tell by the wobbler video the parts come off the printer a bit rough.

Mmmmmm, trout...... ;D

Cheers

Edit - BTW Chris (craynerd) has a very nice build article on the Prusa on Madmodder http://madmodder.net/index.php?topic=7114.0

Hi Billzilla. Yes I've heard nice things about the UP! printer, but it's just a bit out of my price range. :eek:

Cheers

Here's my 3d printed wobbler. I had everything I could printed square. It runs around 1000rpms on 20psi of air. I had the parts printed at a bureau. If anyone is interested I can share the details.
I know its not making chips(there was some reaming and tapping involved), but I do that for a living and was looking for an exercise for learning 3d modeling.
