KS198S Flexible Resin — SLA 3D printing

SLA Available Express available

Soft-touch precision — flexible SLA parts with a smooth surface.

KS198S Flexible Resin 3D printing material

KS198S is Kings' flexible SLA resin at around Shore 82A: it prints smooth, detailed rubber-like parts that SLA's surface quality makes cleaner than filament TPU, suited to seals, grips and ergonomic form studies. It tears under aggressive elongation and drifts under prolonged UV.

What KS198S Flexible Resin is used for

This flexible resin is used for soft-touch and ergonomic parts — grips, seals, gaskets and wearable shapes — where a rubber-like feel is needed with fine SLA detail.

Finishing & post-processing for KS198S Flexible Resin

Parts printed in KS198S Flexible Resin in SLA can be finished a number of ways at KAD3D, from a clean functional surface to a fully painted, display-ready result. The treatments below are the ones we most often apply to this material.

Painting / Priming
Primer fills the last micro-texture so colour coats lie down evenly; the part can then be finished in any custom colour, gloss level or brand match.

What this material supports

✓ Paintable
  • Paint & custom colour: KS198S Flexible Resin primes and paints well, so parts can be matched to any brand colour, gloss level or metallic look.

Most popular finish: Print in the final form; flexible resins are difficult to sand.
