Specifications

PEI (polyether imide) is an emorphous ultrapolymer with outstanding mechanical, thermal and chemical resistance. The 3DXSTAT ESD PEI filament by 3DxTech combines those features with electrostatic discharge protection properties, a base of ULTEM 1010 PEI, and the patented 3DxTech technology of multiwall carbon nanotubes.

This mix creates a filament that can be used to create parts with rigidity, lightness, low moisture absorption, and excellent resistance to a broad range of chemicals such as automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions. Parts 3D printed with 3DXSTAT ESD PEI will preserve their strength and modulus even in very hostile environments with elevated temperatures and humidity. Furthermore, the 3DXSTAT ESD PEI exhibits excellent dimensional stability, highly reproducible dimensions, low heat creep sensitivity, and inherently flame resistant and self-extinguishing properties. Also, like all filaments from the 3DXSTAT family, the ESD PEI is characterized by low particulate contamination and minimal contribution to outgassing and ionic contamination.

Modifying the extrusion temperature changes the surface resistivity of the part

The 3DXSTAT ESD PEI is a conductive material, which means that when an electrostatic discharge event occurs, a part 3D printed with this filament will act as a dissipator, allowing the discharge to safely evacuate along its surface and away from any objects sensitive to damage cause by electrostatic discharge, such as electronics. As it is the case with most 3DXSTAT filaments, the surface resistivity of the ESD PEI can be modified by increasing or decreasing the extrusion temperature of the 3D printer. Thus, higher extrusion temperatures will lead to a more conductive part and lower extrusion temperatures will case the part to be insulating. The data shown in the table must be taken only as reference as the end effect may vary depending on the geometry, thickness and orientation of the printed part, as well as on the 3D printer properties.

The 3DXSTAT ESD PEI filament is ideal for use in critical applications which require electrostatic discharge protection combined with stable mechanical performance in harsh thermal and chemical conditions. Some examples would be industrial conveying, metering and sensing applications as well as for wafer handling or the manufacturing of seminconductive HDD components, jigs, casings and connectors.

The 3DXSTAT ESD PEI filament should be stored properly in order to prevent it from absorbing excess moisture. Humidity is the biggest enemy of filaments as it can result in extrusion problems, poor surface quality of the 3D printed part and a deterioration in its mechanical properties. The best way to store the 3DXSTAT ESD PEI filament is in a sealed bag with desiccant, in a vacuum sealed container or in an intelligent filament container. During printing, the Fiber Three drying case can be used. If the 3DXSTAT ESD PEI filament absorbs too much moisture, it should dried in a filament dryer for 4 hours at 120 ºC.

The 3DXSTAT ESD PEI filament should be printed at a temperature of 360-390 ºC, on a bed heated to 140-160 ºC. It is also recommended to use a 3D printed with a heated chamber if possible as it can help prevent warping. Another way to prevent warping and improve adhesion of the 3D printed part to the printing surface (especially with large parts) is to use the Nano Polymer adhesive designed especially for high temperature technical materials.

In order for the parts 3D printed with the 3DXSTAT ESD PEI filament to achieve their full thermal, chemical and mechanical resistance, they can be annealed in the following way:

First, the part should be placed in a cool, room-temp oven. Supports can be left on the part if there is a risk of part warping without them.
The oven temperature should be set to 149 °C and allowed to stabilise for 1 hour.
The oven temperature must then be raised to 204 °C and allowed to stabilise for a further 1 hour.
After 1 hour at 204 °C, reduce the heat to 149 °C and leave to stabilise for 30 minutes.
After 30 minutes, turn off the oven heat and allow the printed parts to return to room temperature inside the oven while it cools down.

Complex structures and geometries can be created with the 3DXSTAT ESD PEI filament with the help of the ThermaX break-away HTS High Temp Support by 3DxTech, a material is specially designed to work with complex, high temperature filaments.
