For those that work in their DLP projects, what do you think about this breakthrough? metal #3dprinting with DLP. Metal does not need to be melted so higher quality.

Maybe it’s also doable at DIY level :wink:

There are practically zero details about hte process itself in the article, so it’s incredibly hard to estimate what the results from this process are going to be like.

If metal is not melted, I cannot imagine how you change its state with light/UV radiation. Does it change from liquid to solid as for resin?

Maybe it’s something completely different, out of my limited understanding of physics.

I did a little work in powder metallurgy years ago. This company could use common powdered metal with a tiny % of binder to 3D print a fragile metal shape. The shape is then fused into a metal solid at near melting temps in a furnace. The binder would burn off.
