Improved heat resistance and high impact toughness PLA Pro filament is a material based on modified PLA. By adjusting the chemical composition to achieve satisfactory properties required for additive manufacturing, the advantages of both 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, typical of PLA-based materials. The modified chemical composition improves material fluidity, making the filament suitable for industrial use that requires good mechanical strength, high printing efficiency, and especially the possibility to increase printing speed.
Annealing is a process where the temperature is increased to improve strength, heat resistance, and ductility of the product. The temperature the model must reach is called the glass transition temperature. PLA Pro filament can be annealed at high temperature using a heated chamber. Once crystallized, it features increased heat resistance (up to 85"C) and nearly twice the resistance compared to standard ABS. Annealing can be used for parts with simple shapes where increased mechanical resistance and tensile strength are needed.* Uneven heating can cause unexpected deformation and suboptimal performance of printed parts. Typical annealing time for parts with wall thickness about 3.2mm is around 20 minutes.
