ABS CNC machining: cost & machinability

A common, inexpensive thermoplastic. Machines acceptably with sharp tooling but is more heat-sensitive than Delrin — dull tools or aggressive feeds can melt/gum the cut instead of chipping cleanly. Easy to glue and finish; not the first choice for tight-tolerance machined parts.

A plain 40 × 30 × 10mm block in ABS, 3mm stock allowance per side, 2 estimated setups, cncquoter's default shop rate ($95/hr, 25% margin) — computed live by the same cost model at each quantity:

10$13.12 – $21.87$131.22 – $218.69
100$1.88 – $3.13$187.76 – $312.93

This is one fixed sample shape for comparison across materials — your actual part's size, geometry, and setups will change every number here.
