Post Processing of Prints

This articles describes how to clean up and otherwise post-
process 3D prints made with a 3D printer that prints polymers like
ABS or PLA.
Prints always have imperfections, e.g. small parts that stick out
and that you will have to remove. You can do this mechanically or
by using fire, heat or a solvent.
Removing Support Material
Once the part is removed from the platform, pull the skin away
from the part and gently remove the bulk of the support material
used to build the part. Break away as much support material
as possible with your hands. You can also use dental picks and
brushes to remove excess material.
Sanding, grinding, polishing
For example you can use "multi tool" for carving, grinding,
cleaning, sanding, etc. Typical accessories are:
Carving tools (to carve holes that you can't print)
Grinding/sanding tools, to remove imperfections or irregular
bottom layers. Although for the latter, I'd rather use a file.
Cleaning/polishing tools, to remove small imperfections.
Using solvent
Vapor smoothing is a technique for improving the surface finish
of 3d-printed parts. It uses acetone vapor to smooth the surfaces
of ABS prints, removing the layer lines that result from the printing
process..
The are also avaliable chemicals for PLA prints- benzene at an
elevated temperature, chlorinated solvents.
Gluing
Glues for ABS
Super glue
a glue gun that works with ABS
Methylene Chloride/Liquid Solvent Cement
Glues for PLA
UHU POR, an "elastic" glue that is transparent and not very
visible. Probably suitable for toys
