Which material is known for requiring higher print temperatures compared to others such as PLA?

The choice of ABS as the material that requires higher print temperatures compared to others like PLA is appropriate. ABS (Acrylonitrile Butadiene Styrene) typically has a printing temperature range of around 210°C to 250°C. This is significantly higher than PLA (Polylactic Acid), which generally prints well at temperatures between 180°C and 220°C.

The reason ABS requires these higher temperatures is due to its chemical structure; it has a higher melting point and viscosity than PLA, which helps in achieving better layer adhesion and strength in the final product. Additionally, printing ABS at elevated temperatures helps to reduce issues such as warping and ensures that the material flows properly through the printer's nozzle.

In comparison, other materials listed, such as TPU (Thermoplastic Polyurethane), ASA (Acrylonitrile Styrene Acrylate), and PETG (Polyethylene Terephthalate Glycol), generally have printing temperature ranges that are lower than or close to that of ABS but do not consistently exceed the requirements of ABS. Thus, identifying ABS as the material that needs higher temperatures aligns with the characteristics and printing requirements of these thermoplastics.
