What process is typically required to finalize an AM part after it has been printed?

Surface finishing is a crucial step in the additive manufacturing (AM) process that enhances the functional and aesthetic qualities of a printed part. After a part is printed, it often has a rough surface texture due to the layer-by-layer buildup typical in AM. This can lead to issues like poor dimensional accuracy, inadequate mechanical properties, and unsatisfactory appearance.

Surface finishing techniques, such as sanding, polishing, or chemical smoothing, are employed to reduce surface roughness, improve dimensional precision, and prepare the part for subsequent operations or end use. Choosing the right surface finishing process will depend on the material used, design requirements, and the intended application of the part, making it an essential step in achieving the desired quality and performance in AM components.

While welding, heat treating, and electroplating can be necessary in certain contexts or for specific materials, they are not universally required for all AM parts, which is why surface finishing is the more appropriate answer in this scenario.
