3D printing filament Poly PLA 1.75 mm Metallic Silver 1 kg (Polymaker PA07007)

Polymaker PA07007 is a 1 kg spool of PolyLite™ PLA Pro 1.75 mm filament in Metallic Silver, formulated from polylactic acid (PLA) for FDM/FFF 3D printers. This filament combines high rigidity and elevated impact strength typical of PLA Pro with a smooth, slightly silky metallic silver surface finish suitable for prototypes, visual models and functional hobby parts. The 1.75 mm diameter is compatible with most desktop extruders and offers predictable feeding and dimensional stability when printed within the recommended temperature range.

Advantages

PolyLite™ PLA Pro silver delivers improved toughness compared with standard PLA while retaining good stiffness and the ease of printing associated with PLA materials. The metallic silver formulation provides a smooth, silk-like surface without compromising mechanical performance. The filament is provided on a 1 kg spool, offering a practical quantity for iterative prototyping and small production runs.

Suitable for

• Visual prototypes and display models requiring a metallic finish
• Hobby parts, enclosures and decorative components
• Functional prototypes that need higher impact resistance than regular PLA
• Educational projects and rapid prototyping where ease of printing is important

How to use

Load the 1.75 mm filament into your FDM/FFF printer following the manufacturer’s filament loading procedure. Set the hotend temperature between 190°C and 220°C and the heated bed between 30°C and 60°C depending on model geometry and adhesion method. Use fan cooling during prints to improve surface quality. Apply retraction settings appropriate for your extruder type (shorter retraction for direct drive, longer for Bowden). If prints show signs of moisture (bubbling, poor layer adhesion or increased stringing), dry the filament at 55°C for 6 hours before use.

Usage recommendations

For best results, print with moderate speeds (30–70 mm/s) and enable part cooling to preserve the smooth metallic finish; calibrate extrusion multiplier and retraction for your printer to minimize stringing and maximize surface quality.
