Sunlu PC-ABS 1,75 mm / 1000 g

Artno.: SN5-3177-P
Manufacturers: Sunlu

SUNLU PC-ABS is a high-performance engineering filament made from polycarbonate and ABS for robust, heat-resistant and impact-tough 3D printed parts. It combines PC-style heat resistance with ABS toughness and good post-processing behavior. The smooth surface is suitable for painting, coating, electroplating and visually demanding functional parts. Typical applications include automotive interior parts, electronics housings, industrial prototypes, covers, housings and technical components. For best results, a suitable printer, hot bed, strong bed adhesion, dry storage and an enclosed heated build chamber are required.

SUNLU PC-ABS

Technical high-performance PC/ABS blend filament – for strong, heat-resistant, impact-tough and post-processable 3D printed parts with a smooth surface finish. Available in different variants depending on the item.

PC strength combined with ABS processability

SUNLU PC-ABS is an engineering blend filament made from polycarbonate and ABS. It combines the high heat resistance and strength of PC with the toughness and improved processing behavior of ABS. This makes the material suitable for functional prototypes, housings, brackets, electronics parts, automotive interior components, workshop parts, industrial prototypes and parts intended for visual or functional post-processing.

For strong, heat-resistant and functional parts

PC-ABS is much more demanding to print than PLA, PETG or regular ABS, but it offers high mechanical reserves, good impact toughness and increased heat deflection resistance. Its smooth surface is useful for visually demanding parts and post-processing such as sanding, painting, coating or electroplating. For best results, a capable printer with an enclosed, heated build chamber is required.

ENGINEERING PC-ABS

For technical parts with high heat and impact resistance

SUNLU PC-ABS is intended for applications where standard materials are no longer sufficient. The material is suitable for durable prototypes, automotive interior components, electronics housings, technical covers, workshop parts, mechanical prototypes and parts that need to be robust, more heat-resistant and visually refined.

IMPORTANT FOR PC-ABS

Enclosed and heated build chamber recommended

PC-ABS requires high nozzle temperatures, a very hot build plate and a stable chamber. SUNLU lists a chamber temperature of about 90–100 °C. Before purchasing, check whether the printer can handle PC-ABS in terms of hotend, bed, chamber, build plate, adhesive and filament path. For large or sharp-edged parts, stable temperature, strong bed adhesion, raft or brim and slow cooling are especially important.

Typical Applications

SUNLU PC-ABS is suitable for parts where high toughness, increased heat resistance, smooth surface finish and good post-processing need to be combined. For safety-critical applications, long-term chemical exposure, approved production parts or extreme mechanical stress, material suitability should be checked separately.

For demanding technical print projects

SUNLU PC-ABS is especially useful when printed parts require more heat resistance and impact toughness than standard ABS or PETG parts. With a suitable printer, dry storage, strong bed adhesion and a heated chamber, the filament is suitable for professional prototypes and function-oriented engineering workflows.

Note on PC-ABS

PC-ABS is a demanding engineering filament and is not suitable for every desktop printer. Before printing, check maximum hotend temperature, bed performance, chamber temperature, build plate, adhesive and material path. Odors and fumes may occur during printing, so suitable ventilation or filtration is recommended. Large parts require careful adhesion, stable chamber temperature and slow cooling.
