Best Heat Resistant 3D Printing Materials

3D printing opens the door to new possibilities of manufacturing and design. One reason for this is the wide range of innovative and sophisticated materials that can be used for different prints.

For example, there are a variety of heat resistant 3D printing materials that manufacturers can use for objects that need to be able to withstand high levels of heat. In this article, we’ve rounded up the best heat resistant 3D printing materials for FFF printing.

Best Heat Resistant 3D Printing Materials

1. PET-G

A great heat resistant filament is PET-G (polyethylene terephthalate glycol-modified). This 3D printing material is great for beginners because it is as easy to print as PLA, but it is more technically resistant to different stressors, like heat, water, and corrosive chemicals.

Able to withstand operating temperatures of up to 70ºC, PET-G is commonly used for end-use parts that need good mechanical and thermal strength. PET-G is also commonly used for its strong water and moisture resistance, making it an ideal material for water-tight materials and waterproof functions.

2. ABS

ABS (acrylonitrile butadiene styrene) is a commonly used thermoplastic filament that is popular among professional printers due to its stiffness and heat resistance. This 3D printing filament is frequently used for prints that will undergo high-stress applications, like heat or impact.

ABS is a great option for a heat resistant 3D filament, as it can withstand temperatures of up to 100ºC. Along with being heat resistant, it is also water-resistant and impact-resistant, even at low temperatures (-10ºC).

3. PP

PP (Polypropylene) is most well known for its extraordinary chemical resistance, especially against alkali, acids, and organic solvents. But, along with being chemically resistant, it is a heat resistant 3D filament as well.

PP can withstand temperatures of up to 100ºC. Thanks to its smooth, lightweight, and clear appearance, it is often used for food containers, liquid bottles, and other printed parts that come into contact with water or harsh chemicals.

4.PPGF30

PPGF30 (Polypropylene 30% glass fiber) is similar to its non-glass fiber counterpart, but with even higher heat resistance (120ºC) and the added benefit of UV resistance. These two qualities make PPGF30 a great filament option for parts that need to be able to resist a variety of weather conditions.

This 3D printing material is also commonly used in the automotive and aerospace industry thanks to its strong heat and chemical resistance and strength. Even with all this strength, it is still a lightweight 3D printing material and is used to create prints that are equal parts strong, rigid, and weather-ready. 

5. PA

PA (Polyamide) is another thermoplastic that is suitable for heat resistant 3D printing. Featuring a thermal resistance of up to 120ºC, PA can withstand this high heat for an extended period of time, making it a great option if your print will be subjected to heat.

PA is also semi-flexible due to its semicrystalline structure, meaning this material’s strength goes beyond heat resistance. PA is frequently used to print parts that must be exposed to a variety of environments thanks to its high heat, abrasion, oil, and impact resistance. It used to print a variety of manufacturing materials, like jigs, washers, bearings, handles, and snap-fit joints.

6. PAHT CF15

PAHT CF15 (High-Temperature Polyamide carbon fiber reinforced) is a very strong and technically advanced material. Thanks to its 15% carbon fiber, it is both heat and chemical resistant, landing itself as the most heat resistant 3D printing material on this list. 

It can withstand continuous temperatures of 150ºC, making it the ideal filament to use if your print will be subjected to high heat for long periods of time. Along with being heat resistant, PAHT CF15 is also characterized by high stiffness, strength, and printability. This filament is best suited for the most technical printing applications, like moving parts or even metal replacement. 

In conclusion, when it comes to finding a 3D printing material that is heat resistant, the options are plentiful. Heat resistant 3D printing materials come in many different cost points, skill levels, and strengths. Beyond just being heat resistant, many have additional features, such as chemical or water resistance, that can help narrow choosing the perfect filament for your print.
