WORCAM ASA Black 1kg

WORCAM ASA Black 1kg – durable ASA filament for outdoor use

The WORCAM ASA Black 1kg filament is a technical material for demanding applications where long-term resistance to sun, rain and higher temperatures is required. ASA (acrylonitrile-styrene-acrylate) is a modern alternative to ABS with significantly better UV stability and a lower tendency to warp. The black variant of WORCAM ASA is suitable for functional components, prototypes and end-use parts exposed to outdoor conditions – for example mounts, electronic enclosures, parts for garden equipment, automotive accessories or advertising elements.

Main properties

• High resistance to UV radiation and weather – ideal for long-term outdoor use.
• Heat resistance approx. 85–95 °C (depending on part geometry and usage conditions).
• Lower warping and cracking than ABS, easier to print on standard printers.
• Matte black surface – hides layers well, looks professional.
• Good mechanical strength and toughness – suitable for stressed functional parts.
• Dimensional accuracy – stable diameter for consistent extrusion.

Recommended applications

• Outdoor and garden parts (caps, mounts, brackets)
• Automotive – mounts, consoles, covers, frames
• Enclosures and chassis of electronics exposed to sunlight
• Advertising and information boards, signs
• Technical prototypes and functional test parts

Recommended printing parameters

Specific settings may vary depending on the printer, color and model geometry. The following values should be taken as initial recommendations for ASA filaments:

• Nozzle temperature: 240–260 °C
• Bed temperature: 80–100 °C
• Print speed: 40–80 mm/s
• Cooling: 0–30 % (preferably lower, only gentle airflow)
• Chamber: an enclosed build space is an advantage, but not essential for smaller parts

Tips for better adhesion and reduced warping:

• Use an adhesive aid (glue, PEI, special spray) on a clean build surface.
• For larger parts, consider a brim or raft to improve corner adhesion.
• Avoid drafts and strong active cooling of the part.

Advantages of ASA compared to ABS

• Better UV stability – parts do not yellow and become brittle as quickly in sunlight.
• Higher weather resistance – suitable for exterior, facades, garden.
• More pleasant printing – lower internal stresses, less deformation during cooling.

Thanks to these properties, WORCAM ASA is an excellent choice where PLA or PETG are not sufficient in terms of heat and UV resistance.

Safety and handling

When printing ASA, always:

• Print in a well-ventilated area or use filtration/extraction.
• Follow the recommended temperatures and do not leave the printer unattended.
• Store the filament in a dry place, ideally in a sealed container with silica gel.
