What is SLA 3D printing?

Stereolithography (SLA), likewise known as resin 3D printing, is a 3D printing technology that gets rid of high resolution and accuracy, fine details and smooth surface area finishes. SLA can produce incredibly precise and high-resolution components that are capable of being utilized straight in end-use, low-volume manufacturing, or for rapid prototyping.

SLA 3D Printing Materials

Standard

Transparent

Translucent

SLA 3D Printing Post-processing

Standard

All support material is removed and support nibs are sanded smooth.

Standard Sandblasting

Parts can be media blasted for a uniform matte finish.

Polishing

For transparent and translucent SLA parts, they will be polished manually before vapor polishing.

Painting

Painting is avalible for SLA parts with different color based on pantone number.

Plating

Painting is avalible for SLA parts

SLA 3D Printing Advantages And Drawbacks

Advantages

•SLA can create parts with very high dimensional precision and intricate information.

•SLA parts have a smooth surface area finish, making them optimal for aesthetic models.

•Speciality SLA materials are available, such as clear, adaptable, and castable resins.

Drawbacks

• SLA parts are generally brittle and not suitable for functional prototypes, though industrial SLA can produce more functional components for this stage.

• The mechanical properties and visual appearance of SLA parts will degrade over time when the parts are exposed to sunlight.

• Support structures are always required and post-processing is necessary to remove the visual marks left on the SLA part.

SLA 3D Printing Application

Concept Models

The speed, precision, and terrific surface finish of SLA 3d printing components let product programmers create physical snapshots of their styles through the iterative process.

Rapid Prototyping

SLA prototyping is a fully-functional prototype, with materials that can replicate polypropylene, polycarbonate, and inflexible compounds.

Direct Digital Manufacturing

The high precision and consistency of SLA make it an excellent way to build large quantities of discrete or tailored components.

SLA 3D Printing FAQs

1. What’s the best SLA material for prototyping?

We recommend that you choose standard resin for prototypes with a smooth injection molding-like surface finish.

2. What are SLA materials and resins made of?

While FDM raw materials come in spools of solid filament, SLA materials combine short chains of carbon molecules into lengthier chains to become hardened plastic, thanks to a photochemical process. These are photosensitive mixtures of oligomers and monomers that make up liquid resins.
