SLA - 3D Printing
SLA (Stereolithography) is one of the original and most trusted additive manufacturing technologies, using a precisely controlled UV laser to cure liquid photopolymer resin, layer by layer, into a solid part. Unlike processes that melt and extrude material, SLA builds parts through a photochemical reaction—solidifying resin with remarkable accuracy to create smooth, highly detailed components straight off the printer.
Maximum Print Quality
Maximum print quality in an SLA (stereolithography) or resin-based 3D printer can achieve XY-plane resolutions of up to 10 to 19 microns (µm), with adjustable Z-axis layer heights ranging from 0.01 mm (10 microns) to 0.025 mm. This level of precision makes it possible to reproduce microscopic details and mold-quality textures.
Designed for Detail
The layer-by-layer curing process allows SLA to capture fine features, sharp edges, and intricate geometries with a level of detail that few other technologies can match. This makes it the ideal choice for projects where visual quality and dimensional accuracy are just as important as the design itself—from intricate mechanical components to highly detailed models used in presentations and product development.
Precision, Reliability, and Repeatability
SLA is renowned for delivering exceptional dimensional accuracy and consistent results, print after print. From small, highly detailed components to larger precision parts, this technology remains one of the most reliable choices for industries where accuracy cannot be compromised—including engineering, product design, dental, and medical applications.
A Versatile Range of Materials
SLA resins have evolved far beyond simple prototyping materials. Today's photopolymer formulations offer properties tailored to specific needs—rigid engineering-grade resins, flexible and rubber-like materials, high-temperature-resistant formulas, and biocompatible resins for medical and dental applications. This versatility allows SLA to move confidently between visual models, functional prototypes, and specialized end-use parts.
An Exceptional Surface Finish
One of SLA's defining strengths is the quality of its surface finish. Parts emerge from the printer with a smooth, almost injection-molded appearance, dramatically reducing the need for post-processing. This makes SLA particularly valuable for master patterns, visual prototypes, and any application where a flawless, presentation-ready surface is essential.
