Stereolithography Goes Big
https://hackaday.com/2019/10/31/stereolithography-goes-big/
When it comes to hobby-level 3D printing, most of us use plastic filament deposited by a hot end. Nearly all the rest are using stereolithography — projecting light into a photosensitive resin. Filament printers have typical build volumes ranging from 1,000 to 10,000 cubic centimeters and even larger isn’t unusual. …read more (https://hackaday.com/2019/10/31/stereolithography-goes-big/)

BEAM Dragonfly Causes A Flap
https://hackaday.com/2019/10/31/beam-dragonfly-causes-a-flap/
Normal people throw away stuff when it breaks. But not people like us. Or, apparently, [NanoRobotGeek]. A cheap robotic dragonfly died, and he cannibalized it for robot parts. But he kept the gearbox hoping to build a new dragonfly and, using some brass rod, he did just that.
