Polymaker PA07045 CosPLA Version B Filament PLA Easy Sanding Paint Adhesion 1.75 mm

Cosplay models and prototypes often need extensive post-processing, but standard PLA is hard to sand and paint. Polymaker CosPLA Version B solves this with a formulation that sands easily and gives paint excellent grip, so your finished pieces look professional without hours of extra work.

Who is it for

Cosplayers, prop makers, and modelers who want to achieve smooth, paint-ready surfaces on their FDM prints. It is also suitable for anyone who needs a PLA that is easy to finish for display pieces or prototypes.

Main features

• Easy sanding: the material responds well to sandpaper, allowing you to remove layer lines quickly.
• Excellent paint adhesion: paint and primer stick reliably, reducing the need for special primers.
• Standard PLA printing parameters: works with typical PLA nozzle and bed temperatures.
• Consistent 1.75 mm diameter with ±0.03 mm tolerance for reliable extrusion.
• 1 kg net spool weight, vacuum-sealed with desiccant to keep filament dry.

Tips

Start with the lower end of the temperature range and adjust based on your printer. For best paint adhesion, lightly sand the surface, clean off dust, and apply a primer designed for plastics before painting.
