HT-PLA+ filament is a premium material designed for advanced 3D printing needs. One of its standout features is its heat treatability, which allows for an increase in the glass transition temperature from 60°C to 90°C through annealing. This enhances its thermal stability, making it ideal for applications requiring higher temperature resistance. Additionally, HT-PLA+ boasts superior mechanical properties and delivers a smoother surface finish compared to standard PLA+.
