The following is step-by-step instructions for cleaning-up (i.e. sanding, filling, priming and painting) a low resolution plastic part. FDM machines are great, but the affordable ones create parts with a rough surface finish. These instructions, courtesy of FX artist, sculptor and toy maker Brett Klisch.

Step 1: The Back Story
The Dimension BST is a great machine. It?s in the small-company price range and capable of producing functional prototypes with just a little post-build finishing and assembly. For exhibition or theatrical prop quality pieces, the surface finish is pretty crude. Curved surfaces are ribbed. Flat surfaces have thin patches where you can see the honeycomb subsurface. The limited build area often requires parts to be divided into multiple prints. The following is some step-by-step instruction in how Michelle and I clean-up the poor surface finish of simple FDM parts and seem two parts together.
The object we are demonstrating this process on is a replica 1/3 scale model of our living room table that Michelle is making for the set of our current project.
