SLA 3d Printing Service
Stereolithographie Definition

SLA 3D printing (stereolithography apparatus) uses an ultraviolet laser that draws on the surface of liquid thermoset resin to create thousands of thin layers until final parts are formed. A wide selection of materials, extremely high feature resolutions, and quality surface finishes are possible with SLA 3D printing.

Advantages of SLA 3D Printing

No wasted material, it is cost-effective processing.

Lower layer thickness and higher accuracy, especially for the complex pattern.

Short Production cycle, fast production lead time.

A wide range of resin materials is available.

How does Selective Laser Sintering Work?
The SL machine begins the 3D printing process by drawing the layers of the support structures, followed by the part itself, with an ultraviolet laser aimed onto the surface of a liquid thermoset resin. After a layer is imaged on the resin surface, the build platform shifts down and a recoating bar moves across the platform to apply the next layer of resin. The process is repeated layer by layer until the build is complete.

Newly built parts are taken out of the machine and into a lab where solvents are used to remove any additional resins. When the parts are completely clean, the support structures are manually removed. From there, parts undergo a UV-curing cycle to fully solidify the outer surface of the part.

FAQs of SLA 3D Printing
1 What application of SLA?

Concept Models.

Presentation Prototypes.

Prototyping Clear Parts.

Master Patterns for Silicone Molding.

Which material is used for SLA process?

SLA 3D printers use light-reactive thermoset materials called resin. With a wide range of resin materials available, it is very flexible to apply in many industries.

Is SLA a plastic?

SLA is a plastic 3D printing process that uses a thermoset liquid, not a thermoplastic, which is UV-cured in layers to form final parts.
