As a bonus, the RoBLOKS RoGR design is modular and easily adapted to many configurations...
* Art and Sculpture
* 3d printing
* Milling and Machining
* Terrain Mapping, Reliefs
* 3D, 2D Carving
* Assembly
* Plotting
* PCB gravature
* Filligree and Inlay
* Rapid Protoyping
* Laser, Plasma and Welding
* Modeling
* Mold Making
* Patterning
* Chess Partner
...it can be done with RoBLOKS and your ingenuity! The RoGR can even be used to produce parts for more RoGRs and more RoBLOKS modules, qualifying RoGR as a REPRAP.
That's about all they say about it. I think that it's a bit presumptuous to call that a "RepRap" especially since he doesn't mention that you need to purchase an extruder for it to work that way, but you can't argue with good publicity!

Well, I think he's probably referring to the 'rep' bit, if it can machine its own structural elements (and I guess there's no reason why it couldn't). I was just amused that it is referred to as a reprap even though it isn't a rapid prototyper... reprap is just a nifty and useful term. Repmil or reprou don't quite cut it somehow

Lol, I like the chess set! But we'd need black and white plastics. Okay, painting half of the parts black is not too much trouble for now, I guess... Many chess pieces would be possible to fab without > 45' overhangs, I think. We could RepRap a small gripper with a servo (nice pick-and-place synergies here) and a chess algo to controller part for the software. Would be nice publicity to the general public as well

I was thinking about chess pieces last night, strangely enough.
Chessboards don't have fixed dimensions, so they can be scaled to fit your build area The pieces are almost all easy to fabricate, though making a nice knight model would be the tricky bit I feel.
As for plastics, presumably you could have some nice colour ABS filament made up, if you knew the right people. Failing that, would having one set of pieces made out of PLA, and anogther set made out of an opaque plastic provide enough contrast? I'm guessing not, but I haven't seen enough PLA extrusions to be able to tell

it's easy enough to fab cylindrical 'chips' and print appropriate images on top of them.
Aww, but that's so boring
Given that most chess pieces are pretty simple things, width the exception of a few minor details (on my set, the kind and queen's crowns, a slice through the bishop's head, the knight) should be dead simple to throw some nice little models together. I'd do it meself, if I had anything that even looked like a working printer...

... i should look if i have some 3D-data from 'real' chess-pieces, then you can have them converted into STL-files.
Maybe i'll make a run milling the 'boring chess-chips' with my CNC-mill as some sort of intarsia in white and black POM - should look nice

That's the spirit, no need to go all 2D on us
Be sure to take pictures!

... OK, here are the images of a test with milling 'chess-chips':
Layout in Corel, export as DXF (import and CAM in IsyCAM):
First the inlay:
Then the body:
And finally assembled:
... tomorrow i have to make another in black'n'white for my other son ...

Definitely cool
Your sons must be lucky, a dad that can "make anything(TM)"... (or not TM after all...)

So after 2 minutes with winpaint here is my inverted knight with no overhangs of more than 45 degrees. (At least none that can't be fixed fairly easily.)

Hi Chris,
... it's not 'stylish' enough
The paint wouldn't last long enough and a solid two-coloured set is much more impressive.
So for a good reprap-reputation ( "repraprep" - maybe some more branding too
) we should make more worthy thingies ...

What would clearly be the coolest thing is that trick whereby you get a pawn to the far row on the board, and change in into a queen, or whatever. With repchess, it really can change

... my youngest son (7) found the chess-pieces a bit boring too, so i designed for him a butterfly-chip:
Both chips are milled from 5mm thick black POM with 2,5 mm thick white inlays from PMMA.

... yes, it's my aim too adding an extruder beside the mill-head and fuse the software.
So deciding for additive and/or subtractive fabbing is only to select a button on the screen

... and here some nice chess-pieces, where the fabbing would be a little more complex :
It's a rendered sample-scene from Povray - next i'll search a converter from POV to STL (or anoter common format) and retour and try with some other geometries and designing too ...
