The go-to thermoplastic
for enclosures and prototypes.

ABS prints reliably with a heated bed, produces strong parts through layer bonding, can be acetone vapor smoothed for cosmetic finish, and sands/paints well for post-processing. It is more heat-tolerant than PLA and cheaper than engineering plastics. We use ABS FDM for prototypes where SLA cosmetic isn't needed.

Not without protection. Standard ABS yellows and embrittles under UV exposure in 6–18 months. For outdoor applications, specify UV-stabilized ABS grade, paint with UV-blocking topcoat, or switch to ASA (acrylonitrile styrene acrylate) — an ABS variant with UV-stable acrylic substituted for butadiene.

Standard ABS is not FDA food-contact approved by default. Specific grades (ABS-NSF) comply with FDA 21 CFR 177.1010 for food contact. For food or beverage applications, request the NSF-listed grade specifically. Medical-grade ABS (USP Class VI) is also available for skin-contact medical applications.

PC/ABS blend offers ~80% of polycarbonate's impact strength and heat resistance at ~60% of the price. HDT rises from 98°C (ABS) to 110-125°C (PC/ABS). Impact strength and tensile modulus improve substantially. For dashboards, mobile devices, and premium consumer electronics, PC/ABS is the common choice.

Yes — excellent machinability. Use sharp positive-rake tools, moderate speeds (500 m/min for aluminum carbide), and compressed air cooling (not flood — water absorption can cause dimensional drift). Avoid long-reach end mills without coolant, as ABS softens at 105°C Tg.
