Over the past few years, Markforged has aimed to develop materials that open doors to new applications for their users. One such example is Onyx FR, a material capable of self-extinguishing at thicknesses of 3mm or greater.
Now, Markforged is continuing this trend by launching Onyx ESD, or electrostatic discharge, for their Industrial Series composite printers.
What is Onyx ESD?
Similar to the standard Onyx material, Onyx ESD is nylon-based and contains chopped carbon fiber for additional strength. This means that parts made from Onyx ESD will have the same great surface finish and strength that is typically seen from Markforged printers.
Onyx ESD parts are also able to be reinforced with all available continuous fibers, which includes Carbon Fiber and Kevlar.
However, Onyx ESD contains an additional additive that helps to dissipate electric charges which could potentially damage electronics. Parts printed with Onyx ESD have a surface resistance between 10^5 and 10^7 ohms, meaning that static charges flow slowly and do not discharge onto contact surfaces.
Being able to swap between other Markforged materials and Onyx ESD without changing hardware means users can now print parts specifically for anti-static applications. These can include items such as assembly trays, electronics fixtures and custom enclosures.
Onyx ESD launches on December 8, 2020. As mentioned, it will be compatible with the Markforged Industrial Series of 3D printers.
