AnyCubic ASA Filament Black 1 kg — 1.75 mm (MPN: IPHASBK-103)

AnyCubic ASA Filament in black, 1 kg spool, with a 1.75 mm diameter and approximately 395 m length. ASA is a thermoplastic formulated for outdoor and functional use: it offers UV and weather resistance, good dimensional stability at elevated temperatures, and reduced odor during printing compared with ABS. This filament is intended for FDM/FFF 3D printers and is suitable for parts that require durability in changing environmental conditions.

Advantages

ASA provides strong mechanical properties including high tensile and flexural strength, good impact resistance and a heat deflection temperature around 90°C. It resists UV degradation and moisture better than many common filaments, which helps printed parts retain shape, color and function when exposed to sunlight or outdoor conditions. Compared with ABS, ASA typically emits less unpleasant odor during extrusion.

Suitable for

• Outdoor enclosures, housings and fixtures
• Functional prototypes and engineering parts exposed to weather
• Mounts, brackets and components requiring good impact resistance
• Applications needing higher heat resistance than PLA or PETG

When it may not be suitable

ASA can be more demanding to print than PLA: it benefits from a heated bed and preferably an enclosed or well-ventilated printer to reduce warping and manage fumes. Very small decorative models or finely detailed prints that do not require weather resistance may be better produced in PLA or resin, which can give smoother surface detail with less printing complexity.

How to use

Load the 1.75 mm ASA filament into an FDM/FFF 3D printer and set nozzle and bed temperatures according to printer and filament recommendations. Use a heated bed and consider an enclosure to reduce warping and improve layer adhesion. Ensure adequate ventilation when printing to manage emitted fumes. Calibrate retraction and cooling settings for best surface quality; slower cooling and moderate print speeds generally improve layer bonding for ASA.

What to consider before purchase

• Printer compatibility with 1.75 mm filament and required nozzle/bed temperature range
• Availability of a heated bed and, ideally, an enclosed or well-ventilated printing area
• Need for UV and weather resistance versus alternatives like PLA or PETG
• Desired mechanical properties such as tensile strength and impact resistance

Usage recommendations

For best results print ASA on a heated bed with a temperature gradient that matches your printer’s capabilities, use a slightly enclosed build chamber to prevent drafts, and ventilate the room. If surface finish is critical, tune cooling and retraction settings and consider annealing printed parts where appropriate.
