Hey Uwe, I bought a UV light 3-d printer was going to see if I can add
micro-spheres to print cryogenic insulated 3-d structures, light weight
structural insulation that can be 3-d printed. Open Cell Glass Sphere
Foam, open cell like AeroGel that "The Rocket Whisperer" and Mike Patey
low resin approach. I was thinking about trying to arrange the light
sources to only impact at micro-sphere contact points only. Minimize
resin to structural material ratio.

Any chance to thermally sinter Glass Sphere filler?

Obviously a different base material:
(good, easily soluble) sugar cubes are bound via sintering using HF energy heating of the sugar crystal contact zones.

How can resin be applied in a very thin coat on the filler material?
wetting properties/surface tension should then result in a low resin
uncured mass of "just sticking together glass spheres.
UV on and voila.

Are you into FPGAs?

My last big project was MIRO/Rosetta. so Yes and not/less today. :-)
