ABS remains a dependable machining plastic when teams want a balanced material that is easy to work with, cost-conscious, and suitable for functional prototypes or non-extreme end-use parts. It is a frequent choice for enclosures, support parts, hand-held product bodies, and early design validation runs.
Compared with more specialized engineering plastics, ABS is usually selected for practicality rather than maximum heat or chemical performance. That makes it especially useful when the part geometry must be proven quickly before a molded production path is confirmed.
At roughly $3–6 per pound for stock shapes, ABS is among the most affordable machinable engineering plastics. It holds tapped threads well for light assembly, accepts paints and adhesives readily, and machines with a clean surface finish that requires minimal post-processing. The main limitations are moderate heat deflection (~95 °C for general-purpose grades) and susceptibility to UV yellowing if used outdoors without coating.
