The Hackaday tip line has been blowing up with a new Kickstarter for a 3D printer. Although this is a pretty common occurrence around here, this printer is actually very interesting: it’s quite possibly the simplest and cheapest laser resin printer ever.
Most of the 3D resin printers we’ve seen, like the Form1 use mechanical means to raise a print up to the next slice.
