Formlabs ESD Resin (Form 4)

A rugged, static-dissipative resin for printing custom ESD-safe tooling, fixtures, and end-use components that protect sensitive electronics from electrostatic discharge — with high stiffness and impact strength for real production environments.

Formlabs ESD Resin (Form 4) cartridge
Application: ESD-safe tooling
Technology: SLA
ESD Class: Static-dissipative
Post-cure: 70 °C
Key benefit: Protect electronics

Important: ESD performance depends on validated wash + post-cure. Follow the recommended workflow to achieve static-dissipative properties.

ESD-safe production tooling with toughness for the factory floor

Formlabs ESD Resin is a specialty material for producing custom ESD-safe prototypes and production tooling to improve yield and reduce risk in electronics manufacturing. Printed parts are static-dissipative, helping prevent unregulated discharge that can cause component failures.

With high stiffness and impact strength, ESD Resin is designed to withstand daily use on the production line — ideal for custom trays, fixtures, housings, and handling tools where ESD control matters.

Why Choose Formlabs ESD Resin?

Static-Dissipative Protection

Reduce the risk of electrostatic discharge damaging sensitive components by printing tools and parts with controlled dissipative resistivity.

Production-Line Toughness

High modulus and impact performance for tools, fixtures, and trays that get used (and abused) daily on the factory floor.

Clean, Accurate SLA Output

Print precise nests, alignment features, and contact surfaces to improve consistency and throughput in assembly and handling.

Dust & Powder-Friendly

Static-dissipative parts can help reduce dust attraction, improving handling in electronics and powder-sensitive environments.

Applications

ESD Resin is built for custom ESD-safe parts that endure use in electronics manufacturing, assembly, test, and handling.

Consider ESD Resin for:

  • Tooling, jigs & fixtures for electronics assembly and test
  • Custom trays for component handling and storage (nests, stackable inserts, reels)
  • Anti-static prototypes and end-use components
  • Housings and protective covers for sensitive electronics

Tip: For consistent ESD performance, use the recommended post-cure and avoid surface contamination (oils/grease) on contact areas.

Workflow Overview

ESD Resin is a print + wash + post-cure workflow. Post-curing is essential to achieve final mechanical performance and dissipative properties.

  • Print using the ESD Resin preset for your compatible Form 4 printer and selected layer thickness.
  • Wash to remove uncured resin (use fresh solvent for best results).
  • Post-cure at 70 °C for 60 minutes (validated condition) to reach intended properties and ESD performance.
  • Finish contact surfaces as needed (light deburr/sand) while keeping surfaces clean for repeatable ESD behaviour.

FAQ

1) What does “static-dissipative” mean in practice?

It means parts safely dissipate charge buildup through controlled resistivity, helping protect sensitive electronics from sudden discharge events.

2) Do I need to post-cure to get ESD performance?

Yes — ESD Resin is specified post-cured at 70 °C. Skipping or under-curing can reduce both strength and dissipative behaviour.

3) What’s it commonly used for?

Electronics fixtures, trays, nests, housings, and handling tools — anywhere you need durable parts with controlled static dissipation.
