laser for 3d printer

[Per]

I'm both new to the forum and to lasers. I'm currently working on a project to build a SLA 3d printer. the printer hardens a resin with a uv laser.

I intend to use a 405nm laser with around 120 mw, my problem is how to culminate the laser down to a sufficient diameter. I am aming at a resolution at about 7,5 microns. (Is that even in the ballpark??)

Thankful for help!

Go read the thread in the laser shows forum. Someone has that exact same application. Are you two from the same class or something?
