What Are ESD Materials?

Electrostatic dissipative materials, or ESD materials, are designed to control and mitigate the buildup and discharge of static electricity. ESD materials for 3D printing are formulated with additives that impart electrical properties suitable for dissipating static charges. Additives such as carbon nanotubes or black carbon powders are typically incorporated into the base polymer used for 3D printing. As such, it is possible to have both static dissipative and non-static dissipative variants of the same material.

Why Are ESD Materials Useful?

Unlike insulators which store electric charges and prevent their flow, or conductors, which ease the flow of electricity, ESD materials have properties that help to dissipate static charges in a controlled manner. These dissipative properties mean it becomes more difficult for an electric charge to build up to the point where a static discharge may occur. Static electricity can damage sensitive electronic components or be hazardous in specific environments, such as those with explosive gases, liquids, or dust. As such, mitigating the risk of static discharges is often a critical aspect of a product's design. ESD materials are essential in electronics and semiconductor manufacturing, aerospace, and explosive handling industries.


What ESD Options Are Available for 3D Printed Materials?

Filament, resin, and powder-based materials can all be made to be electrostatic dissipative. It's important to note that while some materials contain carbon additives, such as carbon-filled materials, that does not necessarily make them electrostatic dissipative. Additionally, materials that are rated as ESD safe can vary in their electrostatic resistance. Therefore, you should carefully review technical specifications and material properties when searching for a suitable option for your project.


At Xometry, we make it easy to select, quote, and order custom 3D-printed parts made from ESD rated materials. In the sections below, we will look closer at two options we offer, ABS-ESD7 and xESD.

ABS-ESD7

ABS-ESD7™ (acrylonitrile butadiene styrene-electrostatic dissipative) is a type of ABS thermoplastic infused with a carbon filler to make it static dissipative. Much like its non-ESD counterpart, it is a great general-purpose material with good strength and mechanical properties. It's ideal for applications such as electronic housings and creating fixtures for electronic components. ABS-ESD7 is available in the Fused Deposition Modeling (FDM) printing process, enabling you to efficiently create large parts up to 24"x36"x36" at a relatively low cost.

xESD

xESD is a static-dissipative photopolymer resin made available through Nexa3D's LSPc® 3D printing process. This material was carefully engineered to achieve stable and consistent isotropic static dissipative and mechanical properties. It is an excellent option for parts with smaller and more intricate details that take advantage of the high resolution of LSPc® technology. This material and printing process makes it possible to produce parts for end-use applications in low-volume production quantities economically.

    Summary

    Electrostatic dissipative materials like ABS-ESD7 and xESD are excellent choices for parts where mitigating static discharge is essential. Electronic housings, fixtures, connectors, and other components can all benefit from using these materials. The most suitable option for your application will depend on factors such as part size, resolution requirements, order quantity, and cost.
