Diy it?

[amoose136]

The resin needs to be exposed to UV light "X" amount of time to set. You can do that in 2 ways: quick repeated passes (so you would actually see it as lines, not a dot) or slowly so it only needs a single pass... Total amount of exposure time required remains the same in both options!
The latter allows for more accuracy...

Which one would you prefer?

But with a more powerful diode it should be possible to speed up the laser to the limit of the accuracy of the galvo system. There might be hard chemical/physical limits to the curing speed though so it might be that adding more light won't make it cure any faster beyond a certain point.
