High-Resolution, Accurate Parts without Tooling

Stereolithography (SLA) is a powerful 3D printing technology that produces extremely accurate, high-resolution parts suitable for end-use applications, low-volume production, or rapid prototyping. At K Tools Inc., we offer over 15 uniquely engineered SLA materials that can help bring your products to market faster.

Available Finishes for SLA Printed Parts

Matte (Standard)

Supported surfaces will be lightly sanded with 220 or 320 grit sandpaper, then media blasted for a uniform matte finish.

Supported surfaces will be lightly sanded with 220 or 320 grit sandpaper for improved surface quality. Sanding scratches will be visible on supported surfaces.

Supported areas may show small grid-like dots or surface blemishes as a result of support removal.

Available for Accura ClearVue. Only supported surfaces are sanded. Parts will still have visible layering.  High gloss clear coat is applied to enhance natural clarity.

Our provides additional SLA finishing options, including but not limited to sanding, polishing, painting, post thermal processing, and plating to meet your needs.

Applications of Stereolithography (SLA) 3D Printing

Concept Models

The speed, accuracy, and great surface finish of SLA parts lets product developers create physical snapshots of their designs through the iterative process.

Rapid Prototyping

SLA prototyping is a fully-functional prototype, with materials that can simulate polypropylene, polycarbonate, ABS, and rigid composites.

Direct Digital Manufacturing

The high accuracy and consistency of SLA makes it an ideal way to build large quantities of discrete or customized parts.

Benefits of SLA 3D Printing

SLA is the ideal choice for 3D printed models that require accurate features and a smooth surface finish. Our stereolithography service offers both standard and high-resolution options for fine detail parts and can produce components up to a 29″ build area. With the ability to produce complex features with good mechanical properties, an SLA print is often used for final fit checks before moving to injection molding.

In addition, our manufacturing partner network allows us to offer a larger variety of materials than many other 3D printing companies. We provide a wide range of brand materials to suit your needs.

  • High quality parts​.
  • ISO 9001:2015, ISO 13485, IATF 16949:2016, and AS9100D certified.​
  • Free shipping on all US 3D printing orders, no minimums​
