Find the Right 3D Printing Process

3D Materials

Applications for SLA 3D Printing

Concept Models

The speed and versatility of 3D Printing lets product developers create physical snapshots of their designs through the iterative process.

Tooling Parts

3D Printing can be used to create fully-functional prototypes, complete with moving parts, as well as all-in-one assemblies.

Production Parts

The high accuracy and consistency of 3D Printing makes it an ideal way to build large quantities of discrete or customized parts.

SLA 3D Printing for Industrial Applications

3D printing is very versatile and can be set up for relatively hands-free production, which makes them ideal for many industries including automotive, electronics, aerospace & defense, robotics, and medical.

High-Resolution, Accurate Parts without Tooling

Stereolithography (SLA) is a powerful 3D printing technology that produces extremely accurate and high-resolution parts that are capable of being used directly in end-use, low-volume production, or for rapid prototyping. SyncFab offers over 15 uniquely engineered SLA materials that can enable products to be brought to the market

Benefits of SLA 3D Printing

SLA is a go-to choice for 3D printed models that require accurate features and a smooth surface finish. SyncFab offers both standard and high-resolution options for fine detail parts, and can also print larger sized parts and products, offering up to a 29″ inch build area. With the ability to produce complex features with good mechanical properties, SLA 3D prints are often used for final fit checks before moving to injection molding services.

How Stereolithography Works

SLA is an additive manufacturing process that uses ultraviolet (UV) light on a vat of liquid photopolymer resin to selectively solidify part features, building the part layer by layer. The UV light continues this process through the entire vat of resin, selectively curing and solidifying the resin to match the design of the CAD file. Structural supports are created during the pre-build setup process and manually removed after the print is completed. The parts are then washed in a solvent solution to remove uncured resin, and then receive a final post-cure in a UV light oven.

SLA offers higher resolution printing than many other 3D printing technologies, allowing customers to print parts with fine details and surface finishes. SLA 3D printing is a highly-versatile platform for making custom parts in prototype and production settings, often acting as a stand-in for injection molded parts.

Applications of Stereolithography

With a broad range of suitable materials and a rapid turnaround for even complex net-shapes, stereolithography is an ideal tool for a broad range of manufacturing sectors. It is primarily used in auto-engineering, as it enables the cost-effective generation of intricate parts with various surface finishes and fine detailing. Parts can be embossed or engraved, with matte, natural, and myriad other finishes available depending on the manufacturing requirements. While its primary success has been in rapid prototyping and design assistance for the automotive sector, stereolithography is rapidly being adopted at scale in various mechanical modeling sectors.

Available Finishes for SLA Parts

Matte (Standard)
Supported surfaces will be lightly sanded with 220 or 320 grit sandpaper, then media blasted for a uniform matte finish.
Natural
Supported surfaces will be lightly sanded with 220 or 320 grit sandpaper for improved surface quality. Sanding scratches will be visible on supported surfaces.
Strip and Ship
Supported areas may show small grid-like dots or surface blemishes as a result of support removal.
Quick Clear
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.
Custom
SyncFab provides additional SLA finishing options, including but not limited to sanding, polishing, painting, post thermal processing, and plating to meet your needs.
