3D printer filament Spectrum PLA Pro 1.75 mm, Polylactic Acid (PLA), Red, 1 kg

Spectrum PLA Pro 1.75 mm (Red, 1 kg) is a modified polylactic acid filament for FDM/FFF 3D printers compatible with 1.75 mm filament. Designed as an improved PLA material, it combines key benefits of standard PLA with properties closer to ABS to deliver higher impact resistance, elevated tensile strength and enhanced rigidity while maintaining ease of printing. The spool width is 67 mm and the material is intended for general-purpose printing of prototypes, functional models and decorative parts where improved mechanical and thermal performance is desired.

Advantages

Spectrum PLA Pro offers improved heat resistance and higher impact strength compared with standard PLA. The modified formulation increases flowability, enabling better extrusion stability and the potential to print at higher speeds for increased production capacity. Printed parts show higher tensile resistance and rigidity, and the filament is suitable for industrial and hobby applications that require a balance of mechanical strength and printing convenience. The material also accepts post-print heat treatment (annealing) to further raise thermal resistance.

Suitable for

• Functional prototypes and mechanical test parts
• Decorative models and display items
• Small production runs and rapid manufacturing where faster print speeds are needed
• Parts requiring improved impact resistance and dimensional rigidity

Key specifications

• Base material: modified polylactic acid (PLA)
• Diameter: 1.75 mm
• Net weight: 1 kg
• Spool width: 67 mm
• Color: Red (Bloody Red)
• Improved heat resistance after annealing (up to approx. 85°C for crystallized parts)
• Higher impact and tensile strength compared with standard PLA

How to use

Load the 1.75 mm filament into any FDM/FFF 3D printer configured for 1.75 mm material and follow your printer manufacturer's guidelines for filament change and extrusion. Use typical PLA-like printing temperatures as a starting point and adjust nozzle and bed settings according to your printer and model geometry to obtain optimal layer adhesion and surface finish. Because Spectrum PLA Pro has improved flowability, you can evaluate modest increases in print speed while monitoring part quality. Allow printed parts to cool gradually to reduce internal stresses before any post-processing.

Usage recommendations

Post-print annealing can increase the thermal resistance of printed parts: place the part in a controlled heating chamber with even temperature distribution to avoid deformation. Typical annealing for parts with ~3.2 mm wall thickness is around 20 minutes; ensure there are no hot or cold spots in the chamber and follow safe heating practices. Test annealing parameters on sample prints before treating critical parts. Store the filament in a dry environment to preserve printability and mechanical performance.
