> not that impressive

Until you see the scale bar

I believe this happens inside a liquid substrate that cures (hardens) when exposed to light. Instead of building up a shape by exposing a series of flat layers (stacked on top of eachother) one at a time, this exposes the entire 3d shape at once, using holograms.

That replicator involved arbitrary chemistry, so except for faster polymer flavored chicken nuggets, no. :)

But if they can scale up dimensions it is a big opportunity.

Or scale down dimensions.

Or scale up resolution.

Or scale up the throughput for manufacturing small complex parts. Not just one part at a time but many parts in proximity at a time, a bit like chip production.

All four seem likely now that the principle has been proven.

that was my first reaction
