Rigid Resin High Temp
Properties of the High Temp condition, compared with the other Rigid Resin grades.
Choose for hot-air/hot-fluid rigs, mould and lost-wax patterns needing HDT well above 200 °C, accepting very low ductility.
What is Rigid Resin High Temp?
Rigid Resin High Temp is Rigid Resin in the High Temp grade — choose for hot-air/hot-fluid rigs, mould and lost-wax patterns needing HDT well above 200 °C, accepting very low ductility. Rigid Resin High Temp has a tensile strength of 52 MPa (7.54 ksi), stronger than 56% of polymer grades. Elongation at break is 1.4% and the elastic modulus is 3.6 GPa (0.522 Msi). Rigid Resin High Temp has a density of 1.25 g/cm³ (0.0452 lb/in³), heavier than 64% of polymer grades. Its glass-transition temperature is 105°C (221 °F). Glass Filled is the default condition FabDigit quotes; High Temp is available on request or by drawing note.

Working with Rigid Resin High Temp
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 High Temp — frequently asked
What is Rigid Resin High Temp used for?
Rigid Resin High Temp 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 High Temp?
Rigid Resin High Temp has a typical tensile strength of 52 MPa (7.54 ksi) — stronger than 56% of polymer grades. Strength varies by condition: see the 9 listed tempers.
Is Rigid Resin High Temp 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 High Temp 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 High Temp?
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.

What is the maximum service temperature of Rigid Resin High Temp?
Rigid Resin High Temp is rated for continuous use to about 140°C (284 °F), and briefly to 230°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
