3D printing is transforming industries and opening new opportunities for creativity and production. Among the variety of materials for 3D printers, stands out HT-PLA – filament with high temperature resistance, which offers significant advantages over regular PLA filament. In this article, we will take a detailed look at what HT-PLA and its glass fiber version HT-PLA-GF from Polymaker are, as well as why they are the preferred choice for professionals and enthusiasts in the field of 3D printing.
What are HT-PLA and HT-PLA-GF?
HT-PLA (High-Temperature PLA)
HT-PLA is a special type of 3D printing filament, which combines the ease of use of standard PLA with improved mechanical and thermal properties. This material can undergo an additional thermal treatment process known as "annealing," which significantly increases its heat resistance to around 120°C.
HT-PLA-GF (Glass Fiber Reinforced HT-PLA)
HT-PLA-GF from Polymaker is HT-PLA reinforced with glass fibers. This combination provides better mechanical strength, higher hardness, and significant improvement in impact and deformation resistance.
Key advantages of HT-PLA over standard PLA filament
Increased temperature resistance
Standard PLA filament loses structural stability at temperatures around 50-60°C. In contrast, HT-PLA after the annealing process can withstand up to 120°C without deformation. This makes HT-PLA suitable for applications such as automotive parts, electronic components, and functional prototypes used in warmer environments.
Improved mechanical properties
HT-PLA offers better tensile strength and break resistance compared to standard PLA. HT-PLA-GF further enhances these properties thanks to the glass fibers, making it ideal for structural parts subjected to mechanical loads.
Reduced shrinkage and warping
One of the main issues in 3D printing is warping. HT-PLA, and especially HT-PLA-GF, are less prone to warping, which facilitates printing larger and more complex models.
Easy processing and printing
Despite its improved properties, HT-PLA retains the easy processability of standard PLA. The material does not require special temperature settings or printing equipment, making it user-friendly even for beginners.
What is the annealing process and how is it performed?
Annealing (thermal treatment) is a process in which printed models are heated to a specific temperature (around 80-110°C) for a certain period of time. This process alters the crystal structure of HT-PLA, improving its mechanical and thermal properties.
Steps for Annealing:
-
Print the model from HT-PLA.
-
Place the model in an oven at a temperature of 80-110°C for about 15-60 minutes (depending on the thickness of the part).
-
Allow the model to cool gradually to room temperature to avoid stress and deformations.
Applications of HT-PLA and HT-PLA-GF in the industry
Automotive industry
HT-PLA and HT-PLA-GF are suitable for making components such as ducts, light housings, and interior elements that require resistance to high temperatures and mechanical strength.
Electronics
These filaments are used in the production of enclosures for electronic components and parts for devices that operate in high-temperature conditions.
Medical equipment
In the medical field, HT-PLA and HT-PLA-GF are used for creating functional prototypes and parts for devices that require precision and stability.
Tips for successful printing with HT-PLA and HT-PLA-GF
-
Maintain a printing temperature between 190-220°C.
-
Use a heated bed (50-70°C) to reduce the risk of warping.
-
Make sure that the cooling of the model is properly regulated, especially for complex details.
-
For HT-PLA-GF, it is recommended to use hardened steel nozzles due to the abrasiveness of the glass fibers.
