In the world of FDM/FFF 3D printing, there is a family of materials that has stood out clearly above all others for some years now, the PAEK family (polyaryletherketone or polyaryletherketone ether ketone). The materials belonging to this class are semi-crystalline plastics, which withstand high temperatures (around 200 ºC) while maintaining high mechanical strength values.

The PAEK family includes PEEK, PEKK and PEI. All of them have high mechanical strength, chemical resistance and high temperature flammability.

ThermaX™ PEI 1010 filament is one of the materials offered by 3DXtech, a renowned North American manufacturer specialising in technical filaments for professional applications. ThermaX™ PEI 1010 is a high-performance filament made with Sabic's ULTEM™ 1010 resin.

PEI is a high-performance amorphous polymer that combines excellent thermal properties, exceptional dimensional stability, inherent flame resistance and good chemical resistance. Filaments made with ULTEM 1010 resin offer the possibility of creating parts with excellent properties at elevated temperatures due to its high glass transition temperature of 217°C. As a result, ThermaX™ PEI 1010 filament has some of the highest performance in the industry, with excellent mechanical, thermal and chemical resistance properties.

The most outstanding properties of 3DxTech's ThermaX™ PEI 1010 filament are:

High thermal properties. Glass transition temperature of 217°C.
Inherent flame resistance.
Long term hydrolytic stability.
Excellent dimensional stability and highly reproducible part-to-part dimensions.
Good resistance to a wide range of chemicals including automotive fluids, fully halogenated hydrocarbons, alcohols and aqueous solutions.
Stable dielectric constant and dissipation factor over a wide range of temperatures and frequencies.

Thanks to these properties, ThermaX™ PEI 1010 is an ideal material for:

Automotive and transportation applications, providing automotive manufacturers with a cost-effective, high performance, chemically resistant and thermally stable alternative to metal that is strong enough to replace steel in some applications and light enough to replace aluminium in others. For applications such as transmission components, throttle bodies, ignition components, sensors and thermostat housings, etc.
Electrical/electronic applications, making it an excellent choice of material for today's demanding electrical applications, including connectors, MCB components such as housings, shafts and levers, hard disk drive internals, FOUP's, BiTS, PCB's, MCCB internals, Plenum devices, LCD projector internals, fuel cell components and many other applications.

This material is an advanced material that requires the use of a industrial 3D printer that reaches printing temperatures of 370-390°C and a bed temperature of 120-160°C. Due to its difficulty in printing, this filament is recommended for expert users.

To use the ThermaX™ PEI 1010 requires extensive experience in the 3D printing industry and a qualified 3D printer, as an extrusion temperature of 308-400°C, a base temperature of 130-140°C and a chamber temperature of up to 140°C are required, therefore it is recommended to use industrial 3D printers that meet all requirements. To ensure good adhesion to the printing base it is recommended to use Nano Polymer Adhesive, and thus avoid warping effect.

Post-processing:

During the printing of the desired parts with ThermaX™ PEI 1010, internal stresses are generated, just as in any type of plastic, which can develop into unwanted breakages or deformations. Removing these stresses is very simple and only requires a hot air oven and the following 5 steps:

Place the printed parts in a cold oven at room temperature.
Set the temperature to 150°C and let it stabilise for 1 hour.
After 1 hour at 150 ºC, increase the oven temperature to 200 ºC and let it stabilise for another 1 hour.
After 1 hour at 200 °C, reduce the temperature back to 150 °C and leave to stabilise for 30 minutes.
After 30 minutes, turn off the oven and allow the printed parts to return to room temperature inside the oven while it cools down.

This process must be carried out by qualified personnel.
