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 Rigid 10K
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 Rigid 10K — frequently asked
What is Rigid Resin Rigid 10K used for?
Rigid Resin Rigid 10K 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 Rigid 10K?
Rigid Resin Rigid 10K has a typical tensile strength of 82 MPa (11.9 ksi) — stronger than 83% of polymer grades. Strength varies by condition: see the 9 listed tempers.
Is Rigid Resin Rigid 10K easy to machine?
Not especially — machinability is rated fair (35/100, worse than 84% 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 Rigid 10K 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 Rigid 10K?

What is the maximum service temperature of Rigid Resin Rigid 10K?
Rigid Resin Rigid 10K is rated for continuous use to about 130°C (266 °F), and briefly to 150°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
