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.

Design Recommendations

Max Part Size

1200 x 500 x 152 mm [x, y, z] (mill)
152 x 394 mm [d, l] (lathe)

Min End Mill Size

0.8mm
(0.03 in)

Min Drill Size

0.5mm (0.02 in)

Min Wall Thickness

0.5 mm

Undercuts

Square profile, full radius, dovetail profiles

Radii : Depth

Depth must not exceed 12x drill bit 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.

ABS FAQs

Can ABS plastic be machined?

ABS plastic 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.

What is the best way to cut ABS plastic?

Depending on the desired outcome for the project, ABS plastic can either be cut or engraved using CNC milling.

Common uses of CNC machined ABS plastic?

ABS plastic is an excellent choice for general purpose prototyping, pre-molding prototypes, parts that will receive impact and require toughness, or when low cost is desired.

Casting vs CNC Machining: We’re No Longer in the Bronze Age, But Is It Right for Your Part?

Casting, a process whereby molten metal is poured into a mold, has been around for over 6,000 years and is still widely used today. Advances in casting technology enable the casting of high quality parts with tight tolerances, not unlike CNC machining, a newer manufacturing method that’s also widely used.  But have you ever considered […]

3D Printing to CNC Machining: When to Make the Switch

3D printing, an additive manufacturing process, has made its way into almost every industry. From automotive to fashion, it has improved the way companies in a variety of fields do new product development. However, long before 3D printing revolutionized prototyping, CNC (computer numerical control) machining dominated the manufacturing world. If your job is to design […]
