What is SLA 3D Printing?

SLA is a resin-based 3D printing process that uses a laser to solidify liquid resin layer by layer, creating complex geometries and precise parts. This technology enables the production of high-resolution parts with exceptional surface finish.

SLA 3D printing is a process in which a 3D printer uses a laser to cure a liquid resin layer by layer, creating a solid object. This technology is known as stereolithography which produces products with high-accuracy, isotropic, and waterproof prototypes and end-use parts in a variety of sophisticated materials with precise features and a smooth surface finish.

• Laser cures photopolymer resin
• Highly versatile material selection
• Highest resolution and accuracy, fine details

How Does FDM Printing Works?

1. Resin Preparation: A photosensitive resin is prepared in a tank.

2. Laser Solidification: A laser beam is directed onto the resin, solidifying it layer by layer, according to the design specifications.

3. Layer Formation: The laser solidifies each layer, and the build platform moves up or down to accommodate the next layer.

4. Object Completion: The process is repeated until the entire object is printed.

5. Post-Curing: The printed object is removed from the printer and exposed to UV light for final curing.

Types of Materials Used in SLA 3D Printing

Stereolithography (SLA) makes it possible to print with a huge variety of materials, incredibly high feature resolutions, and premium surface finishes. For applications like snap-fit assemblies, automotive styling components, and master patterns as well as higher-temperature applications and exceptional clarity, SLA materials are available in a wide range of mechanical properties and can produce parts with traits akin to injection-molded ABS or polypropylene. There are also clear materials with polycarbonate-like qualities and SLA materials for applications at higher temperatures.

Additionally, the SLA material portfolio we offer includes biocompatible materials that can be used in a variety of medical applications, such as hearing aids, dental tools, and surgical instruments. Other SLA materials that are expendable and offer low ash creation and high accuracy have been developed specifically for sacrificial investment casting patterns.
