Spectrum Filament PLA Pro 1000g, navy blue

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 items, the advantages of PLA and ABS have been successfully combined. It is therefore 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 improved the material´s flowability, making the filament suitable for industrial use that requires good mechanical strength properties, high printing efficiency, and above all the ability to increase printing speed.

Annealing
This is a process during which the temperature is increased, thereby improving the 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. Once crystallized, it exhibits increased thermal resistance (up to 85"C) and almost double 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 may lead to unexpected deformation and suboptimal performance of printed parts. The usual annealing time for parts with a wall thickness of approximately 3.2 mm is on average 20 minutes.*
