< 3D Printing

General Post Porcessing Techniques

Sanding is commonly used on 3D prints to smooth prints or remove small imperfections.[1]

Acrylic paint, model paint, nail polish, markers, and spray paint are common ways to add color to a print.[2][3]

Salt annealing and plaster annealing can give parts a unique finish, and alter strength properties of a print.[4][5] Annealing techniques may be effective to improve prints with slight warping.[6]

A 3D pen can be used on its own as seen here, but can also be used to add small details after printing.

Process Specific Techniques

Post Processing is mandatory for most SLA prints, as extra resin must be removed and desired resin must be hardened.[7][8]

Prints made with ABS plastic can be smoothed with careful application of an acetone vapor.
