How does SLA technology work?
- The build platform shifts down into liquid resin
- Recoater/rollers squeeze resin out from under the part to generate a thin, even layer of resin
- The laser/mirror combination directs the beam according to the path needed for creating object. The resin solidifies wherever the laser beam hits it.
- The process is repeated layer by layer until the build is complete.

Q&A
What are advantages of SLA 3D printing?
SLA is known for it’s ability to produce highly detailed and accurate prints. It’s also is capable of producing intricate and complex geometries that may be challenging or impossible with traditional manufacturing methods. SLA supports a variety of materials, including photopolymers with different properties such as flexibility, transparency, and toughness.
What the printing process looks like at SLA?
The SLA process begins with a digital 3D model, typically created using computer-aided design (CAD) software. Than the digital model is then sliced into thin layers using specialized software. A liquid photopolymer resin is chosen based on the desired properties of the final object. The SLA printer consists of a build platform and a resin tank. The build platform is where the object will be gradually constructed, and the resin tank contains the liquid photopolymer resin.The build platform is lowered into the resin tank just below the surface of the liquid resin.A UV laser beam is directed by mirrors to trace the first layer of the object onto the surface of the liquid resin. The UV light selectively solidifies the resin layer according to the sliced cross-section of the 3D model. After a layer is solidified, the build platform is slightly raised, and the process is repeated for the next layer. Once the printing is complete, the object is typically not fully cured and might still be somewhat sticky. It undergoes a post-processing step where it is fully cured using UV light. Once the printing is complete, the object is typically not fully cured and might still be somewhat sticky. It undergoes a post-processing step where it is fully cured using UV light.
What is an STL file?
An STL (STereoLithography) file is a widely used file format for representing 3D models in a format that is suitable for computer-aided design (CAD) and 3D printing. STL files are commonly used in various applications, including 3D printing, computer-aided design, and computer-aided engineering. They provide a simple representation of the surface geometry of a 3D object and are compatible with a wide range of 3D modeling and printing software.
