About the Material
ABS is a low-cost engineering plastic, widely used for pre-injection molding prototypes. CNC machined ABS is a great option for production-like parts, where detail and mechanical properties are important.

Material Finish
ABS has a somewhat matte finish (think lego bricks) and can be painted. Certain faces may appear more shiny depending on their geometry and how they’re machined. If painting ABS parts, finish will be dependant of the choice of paint.

Depth must not exceed 12x drill bit diameter.
For end mills, depth must not exceed 10x tool diameter.
For end mills, depth must not exceed 10x tool diameter.
Cost Saving Tip
To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
