Will 3D Printed Dice Be Fair?

Is there anything to the process of 3D printing that might make the dice unfair/land on a specific side more frequently? Or will any imperfections be negligible, thus making the dice fair? I'm more concerned about making a d20 than anything else, so…

How do I 3D-print fair dice?

As 3D printers become more and more reliable, their prints get better and better. But FDM printers do have their problems too: you print tiny ovals that smooch together at the edges, and infill makes it awkward at times. So, how do I make a…

Do 3D printers really reach 50 micron (0.05 mm) accuracy?

I've always been wondering about the actual accuracy of 3D printing devices. When looking for the perfect machine to buy, I looked at the speed, price, filaments supported etc, but also accuracy. I once asked somebody who could give me some advice…

What's a good way to secure bushings in a 3D printed part?

I'd like to secure bushings in 3D printed parts. They would be used for a drilling jig. I've seen heat-set inserts, but they've all had threaded interiors. The best idea I can come up with is printing the plastic hole several thousandths of an inch…

How to 3D Print 5-pointed star object that doesn't have flat bottom and hole in the middle?

I'm new to 3D Printing. I've created this star from Blender3d. As far as I know, most printers require a flat bottom. As you can see (blue line is Z-axis, red line is X-axis, green line Y-axis), the star doesn't have any flat sides or…
