A large variety of cutting-edge, advanced heat-resistant resources are available for 3D printing, allowing for new manufacturing and design options. Manufacturers may utilize a variety of thermally resistant 3D printing materials to create items that must tolerate extreme heat. Here, we’ll assist you in determining the ideal heat-resistant 3D printing filament for your needs. We’ve included the finest high-temperature 3D printing materials for fused-deposition modeling printing in this list. These filaments should help you get an idea of what you should be looking for. Without further ado, here are the top six most heat-resistant 3D printing filaments you can use.
One great heat-resistant fiber is PETG, which stands for “polyethylene terephthalate glycol.” This 3D printing material is great for beginners because it prints just as simply as PLA (polylactic acid) but has more structural resistance to different factors such as heat, water, and corrosive materials. It can function in heat as high as 70 degrees Celsius. It’s widely employed in final production parts that need powerful mechanical and heat-related qualities. Additionally, PETG is said to print more clearly and smoothly along layer boundaries when compared to a polymer such as PLA.
PETG’s strong moisture- and water-resistance makes it a great material for watertight and weatherproof applications, such as electronic food storage devices. Beyond this, PETG is also suitable for many different types of projects that require resistance to corrosive materials. Some gasoline tanks are made of PETG for this reason alone.
ABS—or acrylonitrile butadiene styrene—is a well-liked thermoplastic filament among experts due to its stiffness and resistance to heat. This 3D printing filament is often used for products that will be exposed to high-stress conditions such as heat or impact. ABS is famous for having better layer adherence and a smoother print compared to other filaments. This produces a filament that’s far more useful and appealing for goods with rigorous standards.
ABS is an excellent heat-resistant 3D filament because it can withstand temperatures of up to 100 degrees Celsius. Because it’s resistant to not only heat but also moisture and shock, this filament is great for use in any outdoor-related work or projects such as birdhouses, 3D-printed outdoor lights, and even irrigation parts for garden beds.
Polypropylene, often known as PP, is widely recognized for having exceptional resistance to a variety of factors, particularly to alkalis, acids, and organically volatile compounds. But it’s also heat resistant as well as chemical resistant. Temperatures of up to 100 degrees Celsius are no match for PP. Because of its silky, lightweight, transparent look, it’s frequently used for plastic containers, beverage bottles, and other printed items that come in contact with moisture or harsh chemicals.
Besides this, polypropylene is often used in many medical instruments because of its usability with liquids. As such, if you’re looking to print a part that will frequently come in contact with liquids, acids, or heat, this is likely to be the filament that will work best for you.
Similar to its non-glass fiber predecessor, PP GF30—a polypropylene glass fiber mixture—also has UV protection as well as an even greater heat resistance of 120 degrees Celsius. Therefore, PP GF30 is a fantastic fiber option for pieces that must be weather resistant. Due to its excellent thermal- and chemical-resistance and strength, this material is also often utilized in the automobile and aerospace industries. It’s still a light 3D printing material, though, so it may be utilized to produce models that are still sturdy, robust, and weatherproof.
This material is often used in custom industrial applications in which extreme hardness, durability, and heat-resistance are key factors in making a part work. The cost of these types of filaments, which can be somewhat expensive depending on how big the printed part is, reinforces this idea. For this reason, you’ll most often see this type of filament used in custom car components and other engine-related machinery as well as in other types of products that are expected to withstand somewhat extreme force and heat.
Another polymer that may be used for high-temperature applications in 3D printing is nylon copolymer. If your print will be exposed to heat, nylon copolymer is an excellent choice because it has a thermal performance of up to 120 degrees Celsius—plus, it can tolerate this high heat for a long time. Due to its semicrystalline form, nylon copolymer is also semiflexible; hence, its strengths extend beyond heat-resistance. Due to its strong heat-, abrasion-, grease-, and impact-resistance, nylon copolymer is widely used to print components that must be subjected to a range of conditions.
Different production components are often printed using this technology, although at a much more limited capacity compared to the other filaments on this list. This is due to the flexibility that this filament entails. If you need a part that can withstand heat and remail ductile and flexible under stress, a nylon copolymer such as our Phoenix copolymer high-temp nylon filament might be the best option for you.
Nylon Carbon Fiber
High-temperature polyamide carbon fiber reinforcedis a very durable, cutting-edge material. It’s the most heat-resistant 3D printing material on our list because of its carbon fiber content, which also makes it chemical resistant. It’s the best filament to use if your print will be exposed to high heat for extended periods of time because it can resist continuous temperatures of 150 degrees Celsius. Nylon Carbon Fiber has great stiffness, strength, and printability in addition to being heat resistant. This filament is best suited for the most complex printing tasks, such as creating moving components or even replacing metal.
We hope our recap of the top six most heat-resistant 3D printing filaments on the market has been helpful. The options may be overwhelming, but taking the time to learn about each filament will serve you greatly in enabling you to pick the perfect filament for each project you’re looking to build.
