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 satisfactory properties required 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 items with high tensile strength and substantial stiffness, which is typical for PLA-based materials. The modified chemical composition has 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 printing speed.
Annealing
This is a process during which the temperature is increased to improve 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 treated at high temperature using a heated chamber. After crystallization, it exhibits increased thermal resistance (up to 85"C) and almost twice the resistance compared to standard ABS. Annealing can be used on parts with simple shapes where we need to increase mechanical resistance and tensile strength.* Uneven heating may lead to unexpected deformation and suboptimal performance of printed parts. The usual annealing time for parts with approximately 3.2mm wall thickness is about 20 minutes.
