What is Rigid Resin FR V-0?
Rigid Resin FR V-0 is Rigid Resin in the FR V-0 grade — specify for aerospace-interior, rail and electrical enclosures where UL 94 V-0 at 3 mm is mandatory. Rigid Resin FR V-0 has a tensile strength of 55 MPa (7.98 ksi), stronger than 60% of polymer grades. Elongation at break is 2% and the elastic modulus is 3.6 GPa (0.522 Msi). Rigid Resin FR V-0 has a density of 1.5 g/cm³ (0.0542 lb/in³), heavier than 87% of polymer grades. Its glass-transition temperature is 105°C (221 °F). Glass Filled is the default condition FabDigit quotes; FR V-0 is available on request or by drawing note.

Other Rigid Resin grades and fills
Rigid Resin is also supplied in 8 other conditions. The full side-by-side table is on the Rigid Resin overview.
- Glass FilledDefaultDefault choice for stiff, dimensionally stable printed parts: thin walls, jigs, housings and fluid-flow models.75 MPa tensile
- Rigid 10KHighest stiffness and heat resistance in the family — thin-wall turbines, ducting, mould inserts and short-run injection tooling.82 MPa tensile
- Rigid 4000Pick when you need stiffness plus a little more toughness than the 10 GPa grade — jigs, fixtures, snap-in housings.69 MPa tensile
- UnfilledUse for general prototypes and visual models where high stiffness is not required and better ductility/surface finish matters.65 MPa tensile
- FR V-0Specify for aerospace-interior, rail and electrical enclosures where UL 94 V-0 at 3 mm is mandatory.55 MPa tensile
- High TempChoose for hot-air/hot-fluid rigs, mould and lost-wax patterns needing HDT well above 200 °C, accepting very low ductility.52 MPa tensile
- ESDUse for electronics assembly jigs, trays and nests where surface resistivity must sit in the dissipative window.50 MPa tensile
Working with Rigid Resin FR V-0
Is Rigid Resin easy to machine?
Drilling, tapping and light milling are possible but the part is brittle and the glass filler is abrasive — use sharp carbide tools, low feed, no coolant soak, and extract the dust (respirator required).
Can Rigid Resin be welded?
Thermoset: cannot be welded or reflowed; join with cyanoacrylate, two-part epoxy or UV-cure adhesive, and screw into heat-set/threaded inserts rather than tapped resin.
Can Rigid Resin be formed, bent or molded?
Printed on SLA/DLP/LCD at 385–405 nm with a heated (30–35 °C) tank; shake/stir the cartridge because glass filler settles, then IPA wash 5–10 min, dry, and post-cure under UV at 60–80 °C per producer schedule to reach datasheet properties.
What surface finishes work on Rigid Resin?
Sands and primes well; bead-blast or 400–800 grit for a uniform matte, then use a UV-blocking primer/topcoat since bare photopolymer yellows and embrittles outdoors — electroplating requires a conductive base coat.
Rigid 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.

Rigid Resin FR V-0 — frequently asked
What is Rigid Resin FR V-0 used for?
Rigid Resin FR V-0 is typically used for engineering prototypes with thin walls, jigs and locating fixtures, brackets and mounting plates, low-volume mould and tooling inserts, ducting and manifold prototypes and heat-exposed under-hood test parts. In short: stiff glass-filled resin.
What is the tensile strength of Rigid Resin FR V-0?
Rigid Resin FR V-0 has a typical tensile strength of 55 MPa (7.98 ksi) — stronger than 60% of polymer grades. Strength varies by condition: see the 9 listed tempers.
Is Rigid Resin FR V-0 easy to machine?
Not especially — machinability is rated fair (40/100, worse than 81% of polymer grades). Drilling, tapping and light milling are possible but the part is brittle and the glass filler is abrasive — use sharp carbide tools, low feed, no coolant soak, and extract the dust (respirator required).
Can Rigid Resin FR V-0 be welded?
Not readily — weldability is rated not recommended (3/100). Thermoset: cannot be welded or reflowed; join with cyanoacrylate, two-part epoxy or UV-cure adhesive, and screw into heat-set/threaded inserts rather than tapped resin.
What surface finishes work on Rigid Resin FR V-0?

What is the maximum service temperature of Rigid Resin FR V-0?
Rigid Resin FR V-0 is rated for continuous use to about 90°C (194 °F), and briefly to 150°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
