SLA 3D Printing Services 

SLA, or stereolithography, enables the printing of objects using a wide range of materials, achieving exceptionally fine details and a high-quality surface finish.

What is SLA 3D Printing?

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

Functional prototyping, patterns, molds, and tooling

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.

Why choose SLA 3D Printing Services?

SLA parts have the smoothest surface finish of any additive manufacturing process, this adaptable technology is excellent for: 

  • Proof-of-concept and design verification models for appearance
  • Wind-tunnel test models; functional prototypes and models for form and fit testing; high-clarity, transparent products and components

Complex assemblies, internal parts,

  • Molds, Tools, and Die
  • Patterns for metal casting
  • Assembly jigs and fixture

Working Principle of SLA 3D Printing

By using an ultraviolet laser to transform liquid materials and composites into solid cross-sections layer by layer, SLA printers create precise parts directly from 3D CAD data without the use of tooling.

The print bed is then lowered, a fresh resin layer is applied to the component, and successive layers are added until the component is finished. Any wet resin that remains on the part's surface after printing is removed by cleaning the part in a solvent solution.

The final step in the curing process is to place the component in a UV oven.
