Picture of 3D Print a Custom 2-Color Game Piece
I made it at TechShop

This is a custom 2-color game piece. It was designed in Autodesk Inventor 2013, imported to Makerware, and printed on the Makerbot Replicator 2x using ABS plastic.

My original plan was to make a set of Xiangqi  pieces using this method, but at approximately 20 minutes printing time per piece, printing a 32 piece set doesn't seem very practical. So now it's a custom monopoly game piece... or whatever you want it to be.

This was also an experiment to figure out the best way to design something in Inventor to be printed in two colors using the Makerware software and Replicator 2x - the process isn't as straightforward as you might expect. To print using both extruders Makerware requires a separate object for each extruder. If one of these two objects is not in contact with the platform, as in this case, keeping the objects properly aligned for printing can cause difficulties, particularly if they have been rescaled. The two objects that make up this piece include a common base so they can be aligned using the CENTER and ON PLATFORM commands in Makerware. This common base is extremely thin (.00001), so it is not printed.

This is my first project using any of this software or the printer - if I did anything in a dumb way please give me some tips!

Step 1: Make an extremely thin base - useful for printing from Makerware!

In Autodesk Inventor, sketch a circle and extrude it to a very small depth (for example, .00001 mm). The two parts that make up the game piece will be modeled in relation to this base. It should be clear why this is important later.

For some reason the site won't let tack a reply onto your comment. Reply below.

Yep - it would be possible to print multiple pieces on each run, but, like you said, it would still require a lot of printing time. Not sure it's the right tool for the job. I've decided instead of hogging one of the TechShop printers for a couple days, I'm going to make the game pieces (and board) using a laser cutting and engraving tool (after I learn how to use it later today). Should have an Instructable for the project up by the end of the week!

A question from someone who has no experience of 3-D printing (but would dearly like a 3-D printer) :-
Would it be possible to lay out your design so you could print several pieces on the plate at once?
If you did this in 4 batches of 8 pieces the actual printing time would not be improved (as the extruding speed is fixed) but you would drastically reduce the setup and take-off time overhead.
(Although doing the sums, printing time is going to be a little under 11 hours so, as you say, maybe best as a custom Monopoly piece unless you've got your own printer #;¬)
