What your process engineer actually checks

Toughness with dielectric strength

KS908C pairs ABS-like toughness — 12–20% elongation and 58–70 J/m notched Izod — with a 12.7–16.2 kV/mm dielectric strength. That combination makes it a practical brown resin for durable functional prototypes and for electrical or insulating parts, where a standard display resin would be too brittle.

About this product

Kings3D KS908C (also sold under the OEM name WalkPrint5518-KS908C) is a brown, ABS-like laser-SLA resin — tough, accurate and durable, with notable dielectric and electrical-insulation properties. 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 KS908C

A tough, ABS-like SLA resin with useful electrical-insulation numbers.

Tough, ABS-like behaviour

25–30 MPa tensile, 12–20 % elongation and 58–70 J/m notched Izod give durable, less-brittle functional parts that survive handling and fit testing.

Dielectric / insulating

Dielectric strength 12.7–16.2 kV/mm and dielectric constant 4.1–5.0 at 60 Hz — a practical choice for electrical and insulating prototype parts.

Accurate & vacuum-cast ready

Low shrinkage, yellowing resistance and good dimensional stability make KS908C a clean master pattern for vacuum casting and reproducible concept models.

Runs across SLA platforms

A standard 355 nm laser resin (Dp 0.135–0.155 mm, Ec 9–12 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.

Step 01
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.

Step 02
Stocked in California

KS908C 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.

Step 03
Custom formulation on request

Need the resin tuned to a specific toughness, colour, dielectric target, or certification? Tell us the goal and we will discuss a custom SLA formulation with our material partners.

Common questions

Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.

What is KS908C resin and what is it used for?
KS908C is a brown, ABS-like laser-SLA resin from Kings3D (OEM name WalkPrint5518-KS908C) built for tough, accurate, durable parts. It suits functional prototypes, vacuum-casting master patterns, jigs and fixtures, footwear and shoe molds, and electrical or insulating parts that benefit from its dielectric properties. With low shrinkage and yellowing resistance, KS908C holds fine detail and dimensional stability. We supply it from US stock with a batch data sheet and starting exposure parameters for common SLA platforms.
Which 3D printers is KS908C compatible with?
KS908C is a 355 nm laser-SLA resin compatible with most industrial SLA systems, including Kings, UnionTech, ZRapid and 3D Systems laser platforms. It runs at a penetration depth (Dp) of 0.135–0.155 mm and critical exposure (Ec) of 9–12 mJ/cm², at 0.1–0.15 mm layer thickness, with exposure tuned per machine. Tell us which SLA system you run and our materials engineer will share starting parameters so you can print KS908C without a long calibration cycle.
What are the dielectric properties of KS908C?
KS908C offers a dielectric strength of 12.7–16.2 kV/mm and a dielectric constant of 4.1–5.0 at 60 Hz (3.2–4.2 at 1 kHz, 3.2–4.1 at 1 MHz). Those numbers make it a practical option for electrical and insulating prototype parts — housings, covers, and fixtures where the resin should resist conducting current. As with all properties, values are typical after UV post-cure and vary with geometry and process; request the data sheet for design detail.
How tough and strong are parts printed in KS908C?
After UV post-cure, KS908C reaches 25–30 MPa tensile strength, 60–75 MPa flexural strength, 2650–2750 MPa flexural modulus, and 74–82 Shore D hardness (ASTM D638/D790/D2240). Its 12–20% elongation at break and 58–70 J/m notched Izod impact give ABS-like toughness, so parts flex and absorb handling rather than shatter. That balance of accuracy and durability makes KS908C a solid choice for functional prototypes and fit-check parts.
Can KS908C be used for vacuum casting master patterns?
Yes. KS908C is well suited to vacuum-casting master patterns thanks to its low shrinkage, yellowing resistance, dimensional stability, and good machinability for finishing. A smooth, accurate KS908C master transfers crisp detail into silicone molds for short-run urethane casting. UV post-cure the part fully and finish the surface before molding for the best result. Ask our engineer for the recommended post-cure and finishing steps for casting masters in KS908C.
How should I store KS908C?
Store KS908C in its sealed container, away from direct light and heat, below 25 °C and at relative humidity under 38%. Keep it out of UV so it does not begin to cure, and cover the resin between builds. Shake or stir gently before use to re-homogenize it. Because it is light-sensitive, avoid prolonged exposure to ambient UV. Handle with gloves and follow the safety data sheet, which ships with every order.
Can I order a sample before buying a full 10 kg pack?
Yes. Rather than a free-resin giveaway, we offer a paid benchmark print in KS908C: send your STL and we print a representative part you can fit-check and stress in your own process. It is the fastest way to confirm KS908C's toughness, accuracy, and finish suit your application before committing to a full 10 kg pack. Use the Talk to materials engineer button to arrange it.
