![]() Maintenance costs, logistics, installation – all see significant cost reductions in tandem with a decreased part weight. The inherent low specific gravity of PEEK (1.3 g/cm3) is less than half that of aluminum and one sixth that of steel. With 3D printing thermoplastics you can create lightweight objects that are still strong. Everything from extending lifetime by eliminating corrosion, increasing fuel efficiency with lower friction, and handling higher loads/speeds to operating in more extreme chemical environments. The enhanced performance benefits includes endless examples. While PEEK certainly has a high price tag, it has some amazing capabilities that other materials simply don’t have. PEEK 3D printing is quite expensive and you need a well-performing high temperature 3D printer to get the expected result. Without the addition of additives, the flammability of PEEK remains low with one other beneficial feature being the fact that smoke emission is considerably low, the lowest of all thermoplastics when it combusts. Combating this issue is a case of adding a layer of pigment that consists of special soot particles. PEEK can also be weakened when it is subjected to UV radiation. ![]() The temperature at which the polymer structure turns “viscous liquid or rubbery” is 145 degrees Celsius, this is called the Glass Transition Temperature. After that temperature it has great difficulty in resisting chemicals like Chlorine/Bromide, Fluorine, HF and HBr, concentrated Sulphur and Nitric acids, as well as Ketones and Nitrobenzene. However, even though it does have the ability to withstand high temperatures, once it reaches a temperature of 200 degrees Celsius. Some chemical resistances get less at high temperatures The medical industry is keen on PEEK material as well and is adopting it in it’s manufacturing processes due to the fact that it has a low moisture absorption and is easy to sterilize. PEEK also has the ability to handle corrosive fluids, gases and high pressures. Therefor PEEK material is used in a lot of applications that require equipment which can withstand extreme temperatures. The temperature resistance of PEEK goes up to 260 degrees Celsius.
