A Quick Guide to Stereolithography: How It Works

Stereolithography is an effective and efficient 3D printing process that allows companies to create numerous tools or objects for their needs. From prototypes to useful tools, SLA printers can meet client demands, whatever their requirements and specifications. Check out this quick guide to stereolithography and how it works for your creative business.

Additive Creation

SLA printers normally use a tank of photopolymer, or liquid resin, to create different objects. The process involves the use of a high-powered laser to heat certain areas of the resin. As the resin heats up, the laser cures it as it stacks on top of itself, layer by layer. Over time, the object is formed from the resin and is left to rest to ensure its durability.

General Process

With SLA printing, the process involves a few steps to achieve the final product. While some steps are a bit more complex than others, the culmination of each leads to the production of a high-end model. After being modeled during the CAD process via special software, the printer receives the design and prepares it for construction. The layers are made one at a time, cured, and hardened before moving on to the next layer. The result is a smooth and detailed representation of the original design.


SLA-printed models are known for their smoothness and accurate details. Many final touch-ups during the post-processing phase allow the finished product to meet its expectations. During post-processing, washing and preparing the product for the final curing phase ensures it is strong enough to meet its expected use.

For industries that regularly mass-produce niche products, the use of a reliable SLA printing service makes a big difference down the line. Understanding the fundamentals of this quick guide to stereolithography and how it works highlights the efficiency it brings to the table. These printer services are a worthwhile investment when looking for a competitive edge.
