What your process engineer actually checks

Clarity and toughness in one resin

KS168C gives you optical transparency without going brittle — 45–61 MPa tensile, 32–47 J/m notched Izod and 12–21 % elongation. It is the grade for see-through parts that still have to survive handling, assembly and functional testing.

We run a production SLA print center, so a materials engineer — not a call center — answers. Sub-4h reply, NDA standard, with starting exposure and post-cure settings shared for your machine.

About this product

Kings3D KS168C is a clear, durable laser-SLA resin that combines dimensional accuracy, toughness and optical transparency in one material — the grade for see-through prototypes and functional parts that still have to take a load. 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 KS168C

A transparent SLA resin that keeps real mechanical numbers.

Clear, see-through parts

Optical transparency for light pipes, fluid channels, clear housings and flow-visualization models where you need to see inside the part.

Tough, not brittle

45–61 MPa tensile, 32–47 J/m notched Izod and 12–21 % elongation — a transparent resin that flexes and takes an impact instead of shattering.

Accurate and rigid

83 Shore D hardness with 2670–2780 MPa flexural modulus and fine 0.1 mm layers — crisp edges and stable dimensions on detailed geometry.

Runs across SLA platforms

A standard 355 nm laser resin (Dp 0.18 mm, Ec 9.7 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

KS168C 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 clarity, toughness, colour, or certification? Tell us the target and we will discuss a custom SLA formulation with our material partners.

What is Kings3D KS168C resin used for?

KS168C is a clear, durable SLA resin for transparent prototypes and functional parts that also need to take a load. Its mix of optical transparency, 45–61 MPa tensile strength and 32–47 J/m notched Izod impact suits light pipes, clear housings, fluid-flow models, footwear masters and consumer-electronics casings. Because it stays tough rather than brittle, KS168C survives handling, assembly and fit testing better than a display-only clear resin. We supply KS168C from US stock with starting exposure parameters so you can run it on your own SLA machine.

Is KS168C only for Kings SLA printers?

No. KS168C is a standard 355 nm laser-SLA resin, so it runs on most industrial laser-SLA platforms — Kings, UnionTech, ZRapid, 3D Systems and similar machines — not just Kings printers. Its exposure profile (Dp 0.18 mm, Ec 9.7 mJ/cm²) is tuned per machine, and we include starting exposure and post-cure parameters with every KS168C order so you can dial it in quickly. If you are unsure whether KS168C suits your specific printer, a materials engineer can confirm before you buy.

How transparent is KS168C after printing?

KS168C prints with a naturally clear appearance and reaches its best clarity after the recommended UV post-cure. Like most transparent SLA resins, final optical quality depends on finishing: sanding through grits and applying a clear coat or polish takes a matte, stepped surface to a see-through finish. For internal features and flow visualization the as-cured clarity is usually enough; for lens-like optical parts, plan on post-finishing. We can share the post-cure and finishing routine we use in our own print center for KS168C.

What are the key mechanical properties of KS168C?

After UV post-cure, KS168C delivers 45–61 MPa tensile strength, 75–82 MPa flexural strength, a 2670–2780 MPa flexural modulus, 83 Shore D hardness and 32–47 J/m notched Izod impact, with 12–21 % elongation at break. Glass transition (Tg) is about 60 °C and heat deflection is 51 °C at 66 PSI. These numbers put KS168C in tough-transparent territory: rigid and accurate, but with enough elongation and impact resistance to handle functional testing rather than shatter on the bench.

What layer thickness and accuracy can I expect?

KS168C is formulated for 0.1 mm build layers, which balances speed with crisp detail on a laser-SLA system. With 83 Shore D hardness and a 2670–2780 MPa flexural modulus, cured parts hold their edges and stay dimensionally stable, so fine features and thin walls print cleanly. As with any SLA resin, final accuracy depends on machine calibration, part orientation and support strategy. We include starting exposure parameters with KS168C, and a materials engineer can help you tune settings for tight-tolerance geometry.

How is KS168C packaged and shipped?

KS168C ships in a sealed 10 kg bottle with a batch data sheet, from our Los Angeles warehouse, usually within 1–2 business days. Each order includes starting exposure parameters for common SLA platforms. If you need more than 100 kg or an official purchase order, we can put together a volume quote. Not ready for a full bottle? You can request a paid sample print in KS168C to check clarity and fit on a real part before committing to a full order.

Can I get KS168C in a custom formulation?

Yes. Additive Plus is a production print center, not just a reseller, so if standard KS168C is not an exact match we can discuss a custom SLA formulation with our material partners. Tell us your target — greater clarity, higher toughness, a specific colour, or a certification requirement — and we will work toward a resin matched to your part rather than a compromise. A materials engineer handles the conversation, typically replies in under four hours, and NDA coverage is standard.
