Sunlu ABS
Sunlu ABS is a ABS/ASA filament rated to a 95°C heat deflection temperature. This page collects its hardware, environmental, and handling requirements in one place so you can confirm your printer is up to the job before you load the spool.
Material Overview
Sunlu ABS is an engineering-grade 3D printing filament built on a ABS/ASA polymer base. With a heat deflection temperature of 95°C, it is engineered for functional parts that must hold their shape under load and elevated service temperatures — jigs, fixtures, brackets, ducting, and end-use components that would deform in a commodity material.
Selecting Sunlu ABS is a systems decision, not just a spool decision: the polymer base dictates your hotend, your chamber, and your drying workflow. The sections below translate the manufacturer’s data into the concrete hardware and environmental requirements your printer must satisfy.

Nozzle & Hotend
Sunlu ABS is not abrasive, so a standard brass nozzle is perfectly suitable — there is no need to budget for hardened hardware. Keep spare brass nozzles on hand as normal wear items, and retune flow/temperature calibration whenever you swap one. CSV designation: Standard Brass OK.
Enclosure & Chamber
Sunlu ABS benefits from at least a passive enclosure — a fully enclosed chassis (or a draft shield) that traps the heat from the heated bed. This slows cooling, reduces warping and edge curling, and improves interlayer adhesion. An actively heated chamber is not required, but a warm, draft-free environment materially improves results.
Frequently Asked Questions
Can I print Sunlu ABS with a standard brass nozzle?
Yes. Sunlu ABS is non-abrasive, so a standard brass nozzle is safe and recommended. There is no filler to wear down the orifice, so brass gives you the best thermal conductivity and surface finish at the lowest cost.
Does Sunlu ABS require an enclosure?
Sunlu ABS benefits from at least a passive enclosure — a fully enclosed chassis (or a draft shield) that traps the heat from the heated bed. This slows cooling, reduces warping and edge curling, and improves interlayer adhesion. An actively heated chamber is not required, but a warm, draft-free environment materially improves results.
Does Sunlu ABS need to be dried before printing?
Store Sunlu ABS sealed with desiccant and dry the spool before any critical print. As a rule of thumb, dry at 60-80 °C for 4 hours and print from a dry environment to protect layer strength and surface finish.
