I was looking at 3D printers and I wanted to know the maximum achievable resolution in 3D printers that use the extrusion method (NOT the 3D laser printers).

Some manufacturers claim a 20 Micron resolution, with a 0.4 mm extrusion nozzle. I wonder if there are commercially available printers that can do better than that. 1 micron or maybe something in the nano scale?

Not sure what this has to do with Graphic Design. Are you simply unable to find a manufacturer of these 3D printers? What is specifically wrong with the google results to "3d printer 1 micron"? –  KMSTR Jan 29 at 12:25

This question appears to be off-topic because it is about the technical spesification of 3D printers. –  Benteh Jan 29 at 13:22
    
I've seen many questions considering printing here and that's why I have posted this. Feel free to close it! –  Error404 Jan 29 at 13:27

I know a few graphic designers who've worked with 3D printers. It's not mainstream yet, but I wouldn't close a question just because it's about an area on the up. That said, since it's still a fringe area overspilling from product design etc, it's unlikely many people here will have had the chance to do much 3D printing related work. You might get better results elsewhere: a specialist forum, or maybe the techies at superuser.com ? –  user568458 Jan 29 at 13:34

Using a nozzle necessarily limits how small a bit one can successfully place --- that said, there are people trying nozzles as small as 0.2mm ( printrbottalk.com/forum/viewtopic.php?f=28&t=2584 ). There are commercially available printers using stereolithography and inkjet 3D printing which can do much higher resolution than typical FDM machines w/ 0.35--0.5mm nozzles. –  WillAdams May 19 at 12:22
