Continuous 3D Printing Possible With Transparent Polygon Scanning?

I'm not sure which resin printing process you're referring to. Most of the time for consumer-grade resin printers like the one I have, you design your model with a drain hole and print it hollow so the resin can flow out (or add a hole before slicing). Printing fully solid is generally only for when you want it specifically to be solid.

> you design your model with a drain hole

That's indeed what I was talking about. It's a manual process to my knowledge.

And then you end up with a shell, which is not as strong.

To my knowledge, you can't really have this with resin:

Please correct me if I'm wrong :)

I use FDM and resin printers regularly. You can definitely do any infills you want, such as the ones shown in your link. It's not a manual process any more than it is in FDM printers.

Yup, just to add onto this, software like Meshmixer will automate most of this for you. It's still possible to get voids where resin will pool depending on your model, but there's not a whole lot of manual effort involved these days.

Thanks! I am behind the times on resin printers. What hardware/software combo would you recommend? (With FDM, I've happy with Printrbot/Cura).
