If you need a part that can be subjected to higher temperatures, which type of FDM material is recommended?

When considering Fused Deposition Modeling (FDM) materials that can withstand higher temperatures, ABS (Acrylonitrile Butadiene Styrene) is a suitable choice. This is due to its relatively high glass transition temperature, which makes it more stable under heat compared to other common 3D printing materials like PLA. ABS typically has a glass transition temperature around 100°C, allowing it to maintain structural integrity under thermal stress.

In applications where parts may be exposed to elevated temperatures, it's crucial to use materials that will not deform, melt, or suffer from loss of mechanical strength. While other options exist—like Nylon or PETG, which also perform well at certain temperatures—ABS is often favored for its balance of ease of printing, mechanical properties, and heat resistance.

PLA, on the other hand, has a much lower heat tolerance, with a glass transition temperature of approximately 60°C. Therefore, it is less suitable for applications that require parts to endure higher temperatures.

In summary, ABS stands out as the best option among the listed materials for applications involving higher temperature exposure due to its advantageous thermal properties.
