Working with Rigid 10K
Is Rigid 10K 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 10K 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 10K 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 10K?
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 10K 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 10K — frequently asked
What is Rigid 10K used for?
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 10K?
Rigid 10K has a typical tensile strength of 82 MPa (11.9 ksi) — stronger than 84% of polymer grades. Strength varies by condition: see the 9 listed tempers.
Is 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 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 10K?
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.
Can Rigid 10K 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 is the maximum service temperature of Rigid 10K?
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.
What is the difference between Rigid 10K Glass Filled and Rigid 10K GREEN?
Glass Filled is the default condition — default choice for stiff, dimensionally stable printed parts: thin walls, jigs, housings and fluid-flow models. GREEN: only for fit checks and visual mock-ups; strength, stiffness and heat resistance are far below datasheet values and creep is severe.
