Although printer filaments come in several types of materials, two are the most common. These are ABS (Acrylonitrile Butadiene Styrene) and PLA (Polylactic Acid). Both PLA and ABS are sandable, paintable, and bondable.
Can you sand 3D prints?
FDM plastic parts can be sanded by hand or with belt sanders, like wood or automotive parts. Sanding is an inexpensive, effective, and proven method to reach a smooth finish. It is consistently the most widely used finishing technique for 3D-printed parts. Sanding works on all but the tiniest parts.
How do you seal acrylic paint?
Instructions Make sure your acrylic painting is dry before applying the varnish sealer. Apply the first coat of varnish with a wide base coat brush. Wait for the first coat to dry. Apply a second coat going the opposite direction of the first coat. Wait for the second coat to dry.
