Polymaker CosPLA Version A PLA Filament 1.75mm White 1kg – Easy to Sand & Paint

With a dimensional accuracy of ±0.03 mm and a formulation that sands cleanly without clogging, Polymaker CosPLA Version A turns post-processing from a chore into a pleasure. This 1.75 mm white PLA-based filament is engineered specifically for cosplay and prop making, delivering prints that are easy to smooth and ready for paint with minimal effort.

Overview

Polymaker has engineered CosPLA Version A to address a common challenge faced by makers: achieving a smooth, paint-ready surface straight off the build plate. The filament's unique composition promotes better interlayer adhesion, reducing the appearance of layer lines and making it simpler to achieve a uniform finish. Each spool contains 1 kg of white filament with a diameter of 1.75 mm and a dimensional accuracy of ±0.03 mm, ensuring consistent extrusion and reliable prints across a wide range of FDM printers.

What stands out

• Exceptional sandability: The material has been formulated to sand cleanly, allowing you to smooth out layer lines and imperfections without clogging sandpaper or leaving rough patches.
• Excellent paint adhesion: CosPLA Version A bonds strongly with spray paints, primers, and brush-on paints, reducing the need for extensive sanding or special coatings prior to painting.
• Cosplay-ready: Whether you're building detailed armour, sculptural props, or functional models, this filament combines dimensional accuracy with excellent post-processing potential, transforming your prints into polished, professional pieces.
