Some people have asked me about the MakerBot’s print resolution. Although this information can be found on the MakerBot wiki, there’s no harm in disseminating this data. 1 Before I get into some of the technical stuff, let me just say this – the print resolution is pretty freaking good for a $750 DIY robot and it will give a $15,000 commercial printer a run for it’s money.
As a printer that can create objects in three dimensions the normal two-dimensional printer resolution jargon of “DPI” or “dots per inch” doesn’t mean much. The printing resolution for the X/Y axes is 0.085mm and the resolution for the Z axis is 3.125 microns. Most of the time you’re going to have a Z axis resolution of about 1/3 of a millimeter. If you print with layers much smaller than that it will take forever to print without a huge increase in quality.
Or, to put it another way… if you were to hand me two objects one printed on a MakerBot and one printed on a commercial printer, I’m going to ask you why the heck one of them costs $14,000 more than the other. I’ve printed some pretty intricate and detailed stuff on my MakerBot. As I tune it I hope to improve it even more.
- If you haven’t poked around the website, I highly recommend it. There’s a lot of information about the Cupcake CNC, RepRap, fused deposition modeling, robots, and all sorts of stuff. [↩]
