Antistatic resin for engineering that protects electronic components from electrostatic discharge and repels dust.

FormLabs is an American company from Massachusetts, with many offices all around the world. Their product range includes SLA 3D printers, resin tanks, build platforms, washing and curing centers, post-processing kits, utensils and resins themselves. They have even released their own printing preparation software PreForm that allows the user to set up, slice, manage and monitor the printing process in a simple and intuitive way.

SLA resins

Among the many 3D printing technologies, there is the SLA (Stereolithography). As the material it uses photo-activated resin, a synthetic substance composed of light-sensitive monomers and oligomers. Resin changes its structure when exposed to visible light or ultraviolet light. The carbon chains in the monomers and oligomers cross-link and create polymers. The part affected by a selective light source (a laser in the case of SLA) visibly hardens and creates the 3D printed resin model.

Resin is thermosetting, which means that it cures irreversibly. Once the polymer network is formed by chemical changes, resin cannot be turned back into the source material (liquid resin) or reshaped by melting or any other process. This makes resins perfect for printing objects which need to withstand high temperatures and not deform or melt. That property, however, also makes them non-recyclable.

When 3D printing with resin was still a young technology, there were very few resin types available. The yielded prints were fragile, with poor mechanical and thermal properties. This significantly limited the potential applications of SLA 3D printing. Now there are many resin types on the market, with varied optical, mechanical and thermal properties, which makes it a highly versatile material with many applications, from standard non-technical uses (jewelry) to medical (dental) and engineering applications. FormLabs provides a detailed guide to resin types, their features and applications on their website.

Electrostatic discharge ESD resin

One of the biggest challenges in the manufacturing industry is static electricity. Materials with built up static (for example plastic) tend to discharge when close to or in contact with conductive materials, which can permanently damage electronic or other sensitive components. This FormLabs electrostatic discharge (ESD) resin from the engineering resin family, was designed to be used in factory production lines to reduce ESD risks and increase productivity. The task of this resin is to reduce static electricity and protect devices sensitive to electrostatic discharge by giving the electric charge a way to “evacuate” safely.

Another advantage offered by ESD resin is that pieces printed with it repel dust and other particles that accumulate static electricity and provoke system failure in many electronics factories. This is very useful to make dust-free parts for laboratories and high development centres, as most commonly used plastic materials attract dust and dirt by accumulating static electricity.

Moreover, this resin was designed to withstand production line conditions thanks to its high modulus and impact resistance. 3D printing with ESD resin is an affordable option for small and medium enterprises to make and test prototypes in a faster and cheaper way than before, without the risk of mechanical or electric failure.

Pieces printed with this ESD resin require postcuring for the best results. The post curing temperatures and times should be followed as only proper post processing will guarantee that the print fulfills the role it was designed for. There are two easy steps to follow in the post processing of resin:

  1. First, the print should be washed by submersion in cleaner fluid. This step is crucial as it removes the fine layer and any uncured resin. The FormLabs Form Wash washing station, also available in bigger size (Form Wash L) for bigger pieces, was designed for this task. The manufacturer recommends washing prints with ESD resin for no more than 20 minutes and avoiding washing it with other resins to prevent staining.
  2. Next, the print should be cured. This process dries and hardens the outer surface of the print. An object freshly 3D printed with resin has normally only reached 50 - 80 % of polymerization. To reach the desired > 95 % level for optimal physical and mechanical performance, the print needs extra UV light or temperature for the polymerization process to be finalized. That can be achieved with the help of post-curing equipment such as the FormLabs Form Cure (also available in L size for bigger pieces). The recommended curing settings are 60 minutes at 70 ºC.

It is crucial to ground objects printed with ESD resin by using ESD mats or grounding cables. It is the only way for the static charge to dissipate properly.
