ESD-Safe Resin grades and fills
ESD-Safe Resin is supplied in 5 conditions, soft to hard. ESD-STD is the default FabDigit quotes; the values on this page are for it.
Compare all 5 grades and fillsHide
| Grade · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|
impact-modified tough ESD resin | Choose for snap features, thin clips and drop-handled ESD tooling where ductility matters more than stiffness. | 40 | 25 | 75 Shore D | |
conductive / low-resistance ESD resin (10⁴–10⁶ Ω) | Pick when a grounded, near-conductive surface is required (charge draining, shielding-adjacent fixtures) and higher filler-driven brittleness is acceptable. | 45 | 3 | 84 Shore D | |
Flame-retardant ESD resin | Specify when the ESD fixture must also meet flammability requirements (rail, aerospace interiors, enclosures near live electronics). | 50 | 4 | 85 Shore D | |
ESD-STDDefault Standard static-dissipative rigid ESD resin | Default choice for ESD-safe jigs, nozzles, trays and PCB fixtures needing dissipative (not conductive) surfaces. | 52 | 6 | 82 Shore D | |
High-temperature / filled ESD resin | Use for ESD-safe fixtures that see reflow-adjacent heat, ovens or hot test stations; stiffer and more brittle than the standard grade. | 60 | 2 | 88 Shore D |
What is ESD-Safe Resin?
ESD-Safe Resin is an SLA/DLP photopolymer loaded with conductive additives to hold surface resistivity in the static-dissipative range, supplied as standard, conductive, high-temperature, tough and flame-retardant (ESD-FR) variants. It is used for electronics-handling tooling printed to shape, with 52 MPa tensile strength, 6 % elongation, 2.4 GPa modulus, 82 Shore D and 1.17 g/cm³ density. Service temperature is limited to 60 °C, the filler is abrasive and settles in the vat, and any paint or primer on functional faces destroys the ESD rating. Choose ESD-FR where a flame rating is also required. ESD-Safe Resin has a density of 1.17 g/cm³ (0.0423 lb/in³), lighter than 54% of polymer grades. Its glass-transition temperature is 68°C (154 °F). ESD-Safe Resin has a tensile strength of 52 MPa (7.54 ksi), stronger than 56% of polymer grades. Elongation at break is 6% and the elastic modulus is 2.4 GPa (0.348 Msi).

Working with ESD-Safe Resin
Is ESD-Safe Resin easy to machine?
Drilling, tapping and light milling are possible on fully post-cured parts with sharp tools and low feed; conductive filler is abrasive and edges chip, so leave 0.2–0.3 mm stock and avoid coolant soak.
Can ESD-Safe Resin be welded?
Not weldable (crosslinked thermoset); join with cyanoacrylate/epoxy or mechanical fasteners and heat-set inserts, and verify resistance across bond lines.
Can ESD-Safe Resin be formed, bent or molded?
Vat photopolymerization only — stir/shake thoroughly before each print because conductive filler settles, print at 25–40 °C resin temperature, then wash briefly in IPA and heat post-cure per datasheet to reach rated strength and stable resistivity.
ESD-Safe Resin chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| urethane-acrylate / epoxy-acrylate oligobackbone photopolymer network | 35 – 70 | 50 |
| acrylate/methacrylate reactive diluent mviscosity and crosslink control | 20 – 50 | 35 |
| conductive additive (carbon black / CNT sets 10⁴–10⁹ Ω resistance range; causes black/grey opacity | 0.3 – 6 | 2.5 |

What surface finishes work on ESD-Safe Resin?
Parts are inherently black/grey; sanding, priming or painting can insulate the surface and destroy the ESD rating, so keep functional faces as-printed (or bead-blast lightly) and retest per ANSI/ESD STM11.11.
How much does ESD-Safe Resin cost?
ESD-Safe Resin is a high-cost polymer ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
ESD-Safe Resin — frequently asked
What is ESD-Safe Resin used for?
ESD-Safe Resin is typically used for electronics jigs and fixtures, component trays and cleanroom tooling. In short: static-dissipative printable resin; tooling-grade toughness; 60 °C service ceiling.
What is the tensile strength of ESD-Safe Resin?
ESD-Safe Resin has a typical tensile strength of 52 MPa (7.54 ksi) — stronger than 56% of polymer grades. Strength varies by condition: see the 5 listed tempers.
Is ESD-Safe Resin easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Drilling, tapping and light milling are possible on fully post-cured parts with sharp tools and low feed; conductive filler is abrasive and edges chip, so leave 0.2–0.3 mm stock and avoid coolant soak.
Can ESD-Safe Resin be welded?
Not readily — weldability is rated not recommended (5/100). Not weldable (crosslinked thermoset); join with cyanoacrylate/epoxy or mechanical fasteners and heat-set inserts, and verify resistance across bond lines.

What is the maximum service temperature of ESD-Safe Resin?
ESD-Safe Resin is rated for continuous use to about 60°C (140 °F), and briefly to 90°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
