Summary & Key Takeaways

Static Dissipative: Parts safely bleed off charge instead of holding it, protecting sensitive components during handling.
ABS-Like Mechanicals: A 1.9 GPa tensile modulus and 26 J/m notched Izod impact strength stand up to production-line use.
Repels Dust and Powder: The dissipative surface does not attract particulate the way an insulating plastic does.
Tooling in Days, Not Weeks: Print ESD-safe nests, trays, and fixtures on demand instead of ordering machined ESD plastics.

Why Choose ESD Resin?

A specialty material for electronics manufacturing, where an insulating plastic fixture is a liability no matter how well it fits.

Protects Sensitive Components

Static-dissipative parts bleed charge away instead of accumulating it, so nests, trays, and enclosures can hold bare boards and components without risking a discharge event on the line.

Stiff Enough to Be Real Tooling

A 1.9 GPa tensile modulus, 61 MPa flexural strength, and 26 J/m notched Izod impact strength put it in ABS territory, so fixtures hold tolerance and survive repeated handling rather than flexing out of alignment.

Stays Clean on the Line

The dissipative matte black surface repels dust and powder that cling to insulating plastics, which keeps assembly fixtures and inspection nests usable for longer between cleaning cycles.

Source: Formlabs SLA design specifications for Form 3 / Form 4 generation printers, adapted to hold walls to a higher minimum than Formlabs' published figures. ESD Resin's static-dissipative behavior is a bulk property of the printed material, so it applies through the wall rather than only at the surface; no conductive coating or secondary treatment is involved. These are general guidelines; cross-section, hole depth, and part geometry can shift the safe minimums for a specific design. Maximum build size reflects our largest-format SLA printer; actual build size depends on which machine your order routes to.

Frequently Asked Questions

Everything you need to know about designing, ordering, and using ESD Resin parts on Form Now.

What is ESD Resin?

ESD Resin is a specialty stereolithography (SLA) resin from Formlabs for producing custom ESD-safe prototypes and production tooling. Parts printed in ESD Resin are static dissipative and have high modulus and impact strength similar to ABS, which suits them to electronics manufacturing environments.

What does static dissipative mean for a printed part?

A static-dissipative part bleeds electrical charge away in a controlled way rather than holding it like an insulator or conducting it freely like a metal. That prevents charge building up on a fixture and discharging into a sensitive component during handling. See the Formlabs technical data sheet for the measured surface and volume resistivity ranges.

What is ESD Resin used for?

ESD Resin is commonly used for electronics fixturing, anti-static trays and nests, circuit board housings, and assembly tooling, as well as enclosures that protect sensitive electronics from static discharge.

How strong is ESD Resin?

ESD Resin has a tensile modulus of 1.9 GPa, a flexural strength of 61 MPa, a notched Izod impact strength of 26 J/m, and 12% elongation at break, comparable to ABS. Its heat deflection temperature is 62 °C at 0.45 MPa, so it is not intended for use near heat sources such as reflow ovens.

Does ESD Resin need a coating to be static safe?

No. The static-dissipative behavior is a bulk property of the printed material rather than a surface treatment, so it applies through the wall of the part. Machining, drilling, or sanding a printed part does not remove it.

What are the minimum wall thickness and hole size design rules for ESD Resin?

Per Formlabs' SLA design specifications for Form 3 and Form 4 generation printers, we recommend a minimum wall thickness of 1.0 mm for both supported and unsupported walls, and holes should be at least 0.5 mm in diameter. Maximum single-part build size is 353 x 196 x 350 mm.
