Curing with a moving laser spot is an order of magnitude more complicated than with a DLP. Stress issues along with the fact that laser power has to be modulated based on scan velocity make this path a much, much more involved one than it appears at first glance.

Found the kuntman link, Take a look at this, http://laserpointerforums.com/f47/homem ... 32628.html
its something worth considering, I shall build one eventualy.

I'm kind of a perfectionist. I won't be happy with something that is "good enough" for $200 or even $500.
I still believe you get what you pay for, I just don't believe you have to pay 30-80k or more for a quality printer that's achievable for the typical DIY'er for a couple thousand.
Just my personal opinion.

and thats part of why I think this is such a promising (niche) avenue
The more detail the longer the build when drawing single lines the higher the resolution the less time is needed to cure a segment... and then the vibration damping... but 580nm details seems like for 3d printing it would be best limited to small builds. But imagine an investment casting resin printer for 200$, make your d&d character come alive etc.

Speed is one of the main attractions of using the DLP to cure the entire layer at once, in seconds, and having no limits to how complex your build is for it would take each layer the same amount of time.
I would like to see someone create a hardware solution for a laser and galvos, like the Form, but go one step further and have the laser scan the image from top to bottom, like a laser marker. That would be the fastest way to use a laser. May not match the speed of a DLP, but would allow for much higher XY resolution.
