One of the more exotic alternative techniques uses a photosensitive resin that gets hardened layer by layer. The results are impressive, but historically the printers ... build area isn’t very ...
Pushing the button (red, bottom left) pivots the section at the top right, ejecting the plate forward ... magnetic build sheets are useful in both resin and filament-based 3D printing.
There are some solid choices out there for 3D printers, but we've got some reasons why a resin one is a better buy than FDM.
