Once the FDM test print was a success, a print was ordered in polyJet.

Polyjet is higher resulution than current FDM machines. Very, very small scanlines can still be seen in the right light, but you can see in this image that it is a noticable difference between FDM (black on the left) and polyJet (white on the right).

Polyjet can have a rough texture if the support material wasn't removed all the way. Take it from me-- Do whatever it takes to remove all the support material before making your molds, or you will have a rough texture on every part you make.
