What your process engineer actually checks
Heat resistance you can design around
With a glass transition of 135 °C, KS1208H holds stiffness and dimensional stability where standard SLA resins soften and creep. It is the grade to reach for on quick molds, jigs, and prototypes that see heat during test or service.
A materials engineer on the line
Questions on exposure settings, post-cure schedule, or heat performance? We run a production SLA print center in-house, so our engineers answer from real build experience — not a script. Sub-4h reply, NDA standard.
Kings3D KS1208H is a low-viscosity, semi-translucent laser-SLA resin with a 135 °C glass transition — the high-temperature grade for prototypes and quick molds that must hold their shape under heat. It is a standard 355 nm resin, compatible with most industrial laser-SLA systems, and we supply it from US stock with the starting parameters to run it.
Why engineers choose KS1208H
A rigid, heat-stable SLA resin with production-ready mechanical numbers.
135 °C glass transition
Holds stiffness and dimensional stability where standard resins soften and creep — the reason to pick KS1208H for heat-exposed parts.
Strong and rigid
65 MPa tensile, 110 MPa flexural, 2720 MPa flexural modulus and 87 Shore D after UV post-cure — an engineering resin, not a display resin.
Low 340 cps viscosity
Thin, free-flowing resin recoats cleanly on large build platforms, supporting fine 0.08–0.12 mm layers without dragging or trapped bubbles.
Runs across SLA platforms
A standard 355 nm laser resin (Dp 0.115 mm, Ec 13.5 mJ/cm²) — compatible with Kings, UnionTech, ZRapid, 3D Systems and similar industrial SLA machines.
How we supply it
A production print center supplying proven resins — not a warehouse reselling boxes.
Proven, then stocked
We run a production SLA print center in-house. We only stock resins we have printed and validated ourselves — so what ships is a known quantity, not a catalog listing.
Stocked in California
KS1208H ships from our Los Angeles warehouse in 1–2 business days, sealed with a batch data sheet, plus starting exposure parameters for common SLA platforms.
