Filament Spectrum PLA Matt 1.75 mm Grey 1 kg – Polylactic Acid 1.75mm

Spectrum PLA Matt 1.75 mm Grey is a 1 kg spool of polylactic acid (PLA) filament designed for FDM/FFF 3D printers accepting 1.75 mm filament. The formulation has been modified to produce a matte surface finish that reduces shine and minimises visible layer lines on side surfaces. The filament retains typical PLA printing advantages such as easy extrusion, low warping and good interlayer and bed adhesion, while offering improved temperature and impact resistance and reduced brittleness compared with standard PLA.

Advantages

The matte finish produces non-reflective prints that require less post-processing to hide layer lines. Spectrum PLA Matt prints reliably on standard desktop 3D printers and combines low shrinkage with consistent dimensional stability. The material offers improved toughness and thermal resistance relative to basic PLA formulations, while preserving straightforward print settings and good layer bonding.

Suitable for

• Prototyping and concept models for industrial and product design
• Architectural models and interior design mock-ups
• Educational projects and classroom demonstrations
• Household parts and decorative prints where a matte surface is preferred

Key specifications

• Material type: modified polylactic acid (PLA) with matte additives
• Diameter: 1.75 mm
• Net filament mass: 1 kg per spool
• Finish: matte, dark grey
• Typical properties: low shrinkage, good interlayer adhesion, improved impact resistance and reduced brittleness
• Packaging: vacuum-sealed spool with desiccant for moisture protection

How to use

Load the 1.75 mm filament into the printer according to the printer manufacturer’s instructions. Preheat the nozzle and print bed to temperatures recommended for PLA-based materials; adjust nozzle temperature and print speed as needed to achieve optimal surface finish and layer bonding for the matte formulation. Use standard PLA bed adhesion methods such as a heated bed, painter’s tape or glue stick when required. Monitor first layers to ensure proper adhesion and adjust Z-offset if necessary.

Usage recommendations

For best results, print with moderate nozzle temperatures and slower outer wall speeds to enhance the matte appearance and reduce visible layer seams. Store unopened spools in their original vacuum packaging with the desiccant; once opened keep the filament in a dry box or sealed bag with silica gel to minimise moisture uptake.
