Re: [diy_3d_printing_and_fabrication] Highest DIY XY resolution ?
- Form1 uses 120mW 405nm diode:
"Above is another view of the laser. According to the safety warning bundled
with the printer, it is a 405nm, 120mW violet laser diode." 
I burned down a __supposedly__ 700mW 405nm laser diode from bluray-burner (it's
really not vise for software guy to solder constant current driver, isn't it?)
The more powerful laser diodes are not easy to source- most of which are
available for reasonable prices (ie < $100) actually come from replacement sleds for
blu-ray writer drives.

· F-theta lens, 405nm, STS-0580/173, (US)$ 4733 each
Is that a lot ? Not if one is able to build large objects fast and accurate, I think.
What other expensive (new) elements a printer requires, when (re)using parts of the HP LaserJet ?
