It looks interresting but from some of the images/video they have it looks like the object shrinks alot when fired which might be problematic if you plan to use it for something functional.

but if it cant float on salt water then getting it to work might be a bit more troublesome, but the peachy printer should be able to work the same way as other resin printers by shining through a piece of glass and having a platform move using a stepper mother instead of the dripper
