our custom made heated build stage for our MakerBot CupCake CNC is working extremely well. here you can see 4 pulleys being printed at the same time. there’s no raft (saves time, plastic, and headache), and ZERO warping. excellent! the etched acrylic may stick a bit too well. we’ll have to try regular, unetched acrylic next (which will be less expensive anyway).
say hello to mass manufacturing.
