The question about heat-resistant materials is undoubtedly one of the questions we receive most frequently from our customers.
We have therefore decided to offer you a brief overview of heat-resistant materials at this point.
PEEK
Among the heat-resistant, 3D printable plastics, polyetheretherketone (PEEK for short) can be considered one of the most interesting. Depending on the composition, PEEK is heat-resistant up to at least 235°C. PEEK Carbon even has a heat resistance of up to 260°C.
At the same time, PEEK has a number of other interesting properties. This material has a high level of chemical resistance, both to organic and to inorganic substances.
In addition:
PEEK Carbon
As mentioned above, PEEK Carbon, which was specially developed to be heat-resistant, can even handle processing temperatures of up to 260°C. This material, available since May 2018, is particularly well suited for aerospace purposes. However, PEEK Carbon is also popular in the automotive industry. After all, this material withstands the temperatures in engine compartments or bonnets without any problems. Other typical applications can be found in the oil and gas sector.
metal 3D printing
However, completely different processing temperatures are possible in metal 3D printing. Here, for example, the nickel alloy Inconel withstands temperatures of up to 1000°C without warping. Since milling tools often get stuck, break off or become blunt in this material, Inconel is difficult to process using conventional methods. 3D printing can also help here. Inconel is used in particular for gas turbines, internal combustion engines or heaters.
