What is SLA?

Stereolithography (SLA) is a type of 3D printing technology that uses a liquid resin that is cured by a focused light source, typically a laser or UV light. The resin is contained in a tank, and a build platform is submerged in the resin. The light source is then used to selectively harden the resin, layer by layer, until the desired shape is achieved.

SLA Pros & Cons

One of the key advantages of SLA printing is its high level of detail and precision, which makes it well-suited for creating parts with complex geometries and intricate details. Additionally, SLA printing is versatile with a wide range of materials, including tough, flexible, translucent, and even conductive resins. This makes it a popular choice for a variety of applications, from product design and engineering to medical and dental applications.

However, one potential drawback of SLA printing is that parts printed with resin material can gradually turn yellow with long-term exposure to direct sunlight. This can be challenging for some applications, particularly those where parts need to maintain their original color over time. In order to prevent yellowing, 3DSPRO offer 3D+ services. These services can include UV-curing, coating, or other treatments to help protect the part from sunlight exposure and prevent yellowing.

Overall, while yellowing can be a potential challenge for SLA printing applications, the high level of detail and precision offered by the technology, as well as its versatility with a wide range of materials, make it a popular choice for many different types of applications. By working with 3DSPRO and taking advantage of additional post-processing services, it is possible to mitigate the risk of yellowing and achieve high-quality, durable parts with SLA printing.

How are people utilizing SLA?

SLA printing is widely used in industries such as comsumer products, art and design, and medical devices, and is increasingly accessible to hobbyists and makers. It is the go-to choice when making look-like prototypes because parts printed with SLA usually have smooth surface and will be easy to paint.
