3D printer filament Spectrum Filament ABS GP450 - 1.75 mm (80346)

Spectrum Filament ABS GP450 is a 1.75 mm ABS filament formulated for FDM/FFF 3D printing of durable parts and functional prototypes. Designed to provide good impact resistance and dimensional stability, this ABS material is suitable for projects that require sturdiness and predictable behavior during post-processing. The filament is intended for use on printers equipped with a heated bed and configured with standard ABS print settings.

Advantages

ABS GP450 offers balanced mechanical properties with emphasis on impact strength and thermal resistance compared to more brittle plastics. The filament delivers consistent extrusion and layer adhesion when printed with appropriate temperature control, reducing warping on moderate-sized parts. Its compatibility with common secondary operations such as sanding, drilling and solvent smoothing makes it practical for functional components and finished prototypes.

Suitable for

• Durable consumer parts and housings
• Functional prototypes and mechanical components
• Workshop jigs, fixtures and tooling aids
• Small-scale production of impact-resistant items

Key specifications

• Material: ABS (acrylonitrile butadiene styrene)
• Diameter: 1.75 mm
• Recommended printer technology: FDM/FFF
• Mechanical focus: impact resistance and dimensional stability
• Compatibility: requires heated bed; suitable for common ABS print temperatures

How to use

Load the 1.75 mm ABS filament into an FDM/FFF printer that supports ABS. Set the nozzle and bed temperatures according to your printer and material guidelines—typical nozzle temperatures for ABS are higher than for PLA, and a heated bed is required to reduce warping. Use an enclosed build chamber or minimize drafts where possible to maintain stable ambient temperature. Calibrate extrusion flow and first-layer height before printing, and allow parts to cool gradually after printing to preserve dimensional stability.

Usage recommendations

For optimal results, print on a heated bed with a suitable build surface (e.g., PEI, ABS slurry or suitable adhesive) and use a nozzle temperature and bed temperature matched to your printer and filament batch. Consider enabling a brim or raft for large flat parts to reduce edge lifting, and perform necessary post-processing such as annealing or solvent smoothing when precise dimensions or surface finish are required.
