Spectrum 3D filament, PLA Pro, 1,75mm, 1000g, 80138, military khaki

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 additive manufactured objects, 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, typical for PLA-based materials. The modified chemical composition has improved the material´s flowability, making the filament suitable for industrial use that requires good mechanical strength properties, high printing efficiency, and especially the ability to increase print speed.
Annealing
This is a process where the temperature is raised to improve the strength, heat 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 nearly twice the resistance of standard ABS. Annealing can be used for parts with simple shapes where increased mechanical resistance and higher 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 about 3.2mm is on average 20 minutes.
