Improved Thermal 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 the desired properties for additive manufactured objects, the advantages of PLA and ABS have been successfully combined. It is thus 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, high printing efficiency, and especially the ability to increase printing speed.

Annealing
This is a process where the temperature is increased, improving strength, thermal resistance, and ductility of the product. The temperature that the model must reach is called the glass transition temperature. PLA Pro filament can be heat treated using a heating chamber. Once crystallized, it exhibits increased heat resistance (up to 85"C) and almost twice the resistance compared to standard ABS. Annealing can be used on simple-shaped parts where increased mechanical resistance and tensile strength are needed.* Uneven heating can lead to unexpected deformation and suboptimal performance of printed parts. The usual annealing time for parts with a wall thickness of about 3.2mm is approximately 20 minutes.

Key Features:
- good alternative to styrene-based materials
