Improved Heat Resistance and High Impact Toughness
PLA Pro filament is a material based on modified PLA. By orienting the chemical composition of the material to achieve satisfactory properties required for additively manufactured objects, the advantages of PLA and ABS have been successfully combined. It is therefore possible to achieve high impact resistance of printed parts with high tensile strength and substantial stiffness, which is typical for PLA-based materials. The modified chemical composition improved the material’s flowability, making the filament suitable for industrial use requiring good mechanical strength properties, high printing efficiency, and especially the possibility to increase print speed.

Annealing
This is a process during which the temperature is raised, thereby improving the strength, heat resistance, and elongation of the product. The temperature the model must reach is called the glass transition temperature. PLA Pro filament can be treated at high temperature using a heated chamber. Once crystallized, it exhibits increased thermal resistance (up to 85"C) and nearly twice the resistance compared to standard ABS. Annealing can be used on parts with simple shapes where increased mechanical resistance and tensile strength are needed.
*Uneven heating may lead to unexpected deformation and suboptimal performance of printed parts. The typical annealing time for parts with a wall thickness of approximately 3.2 mm is on average 20 minutes.*
