PolyLite™ CosPLA is a specially formulated PLA designed specifically for cosplay props and models. It offers improved sandability, durability, and paintability, making post-processing much easier than with standard PLA.
This filament is available in two optimized versions:
Version A – Offers exceptional ease of sanding and painting, ideal for high-detail finishing work.
Version B – Provides enhanced durability, perfect for larger or more functional prop elements.
> ⚠️ Safety Note: Always wear appropriate PPE (Personal Protective Equipment) such as a mask and goggles when sanding printed parts to avoid inhaling fine particles.
What is the difference between Version A and Version B of PolyLite™ CosPLA?
During the development of PolyLite™ CosPLA, we created a formula that significantly outperformed standard PLA in both durability and ease of sanding and painting. Through continued research, we discovered two separate advancements:
One that greatly improves sandability
Another that nearly doubles the material’s toughness.
However, due to technical limitations, both enhancements could not be combined into a single formula. As a result, we decided to release two specialized versions:
Version A – Optimized for maximum sandability and paintability
Version B – Optimized for maximum durability and toughness.

What is the Heat Resistance of PolyLite™ CosPLA?
Through market research, we identified the four key needs for cosplay applications (in order of importance):
1. Sandability
2. Durability
3. Paintability
4. Heat Resistance
PolyLite™ CosPLA was specifically engineered to meet the top three priorities, offering excellent sanding, improved toughness, and easy painting. However, its heat resistance remains similar to standard PLA, with a glass transition temperature of around 60°C.
While we have developed other formulas with higher heat resistance, these often come at the cost of printability, which is a common tradeoff in 3D printing materials. Achieving both high heat resistance and easy printability remains one of the most challenging goals in filament development.
For cosplay applications requiring higher heat resistance, we recommend:
PolyLite™ ABS – Offers good heat resistance, durability, dimensional stability, and sandability while still being printable with a properly enclosed printer.
PolyLite™ ASA – Similar to ABS but with added UV and weather resistance, ideal for outdoor or convention use.
What Our Beta Testers Are Saying
> “It prints just like PLA but sands easier!” “I normally spray paint PLA with filler primer before sanding, but this allows for the option of sanding first.”
> “The sanding for Version A was a breeze compared to normal PLA, and I feel it's plenty strong for props.” “Version B was stronger, but the ease of use and surface finish of Version A outweighed the extra strength.”
> *“I prefer my cosplay pieces to be primed in grey, so the fact that it’s already grey makes my job easier.”
> “Less stringy than regular PLA.”
> “It prints just as easily as PLA.”
> “Easier to sand and ready to paint without primer.”
> “Prints very smooth.”
> “Easily printable—didn’t change any settings, and the filament performed beautifully.”
> “The color is really nice to work with, too.”
> “For Version B, I accidentally printed at PETG temps—and it still printed just fine!”
