A question for the laser experts,not about engravers but,
As slow progress is made on my DLP 3dprinter, I am now thinking of different light sources,
the plan is to have interchangable "lamps" including a 405nm laser, can anyone advise me on
a goog one to buy, preferably with driver, and the optics needed (I assume) to defocus the spot
into the light gate, will I need a beam expander?.
I understand that 405nm does not harm the dlp protective coating, whilst cureing uv resin???.
