Infill

[Hugues]

Thinking of it, partial infill with DLP is great because it does not require more time to print, only less resin, and surely we can create smart infill to improve the strenght/weight ratio. It seems a must-do for DLP.

I believe these guys are using a similar technique to DLP to do just that, albeit at lower resolution, but it's just a matter of time until we have projectors who can achieve this resolution for us DIY:
