SLA: What is This Process and Where it is Applied in the Industry?

2019-06-14 15:10:18

The continuous improvement and advancements in 3D printing technology are changing the way businesses approach prototyping and production. As this technology is becoming more affordable and accessible, 3D printing is being integrated into workflow across different development cycles. In particular, Stereolithography (SLA) 3D printing has undergone several critical changes. While traditional SLA machines are monolithic, cost-prohibitive and require skilled technicians to operate, modern SLA machines are available as small format desktop printers that are versatile and produce industrial quality output.

SLA rapid prototyping has also become very popular in the industry because it allows manufacturers to produce high-accuracy, isotropic and watertight prototypes and parts with fine features and smooth surface finish.

For people who are new to this technology and wondering what exactly this is, here we are going to explain it in brief.

What is Stereolithography?

Stereolithography is a type of additive manufacturing technology known as vat photo polymerization. In short, it is called SLA. SLA machines are also designed on the same principle as other additive manufacturing technology based machines. It uses a light source, usually a laser or projector, to cure a resin into hardened plastic. The main difference between machines is in the arrangement of the core components such as a light source, a build platform and a resin tank.

Now, let’s check out where this technology is applied to understand what kind of businesses can benefit from SLA rapid prototyping services.

Applications of SLA Rapid Prototyping

SLA 3D printing is promoting innovation and helping businesses belonging to different industries including engineering, healthcare, dentistry, manufacturing, jewelry and much more.

Product Design and Engineering

SLA rapid prototyping with 3D printing enables and empowers engineers and product designers to transform their ideas into realistic concepts and concepts to high fidelity prototypes that seem and function just like final products and guide products via a series of validation stages for mass production.


Technology like SLA allows manufacturers to automate their production processes and streamline workflow through prototype tooling and 3D printing custom tools, molds and manufacturing aids. This approach of manufacturers proves to be highly cost-effective and better lead times when compared with the traditional manufacturing process. SLA rapid prototyping also reduces defects while increasing quality, speeding up the assembly, and optimizing labor effectiveness.


With the help of SLA 3D printing technology, the healthcare industry can deliver devices which are customized to serve the requirements of each unique individual in a better way. Thus, this is also opening doors to high-impact medical applications while saving a significant amount of time and costs.


One of the biggest benefits of 3D printing is that it can provide high definition physical models which are widely used in sculpting, prop making and character modeling in the entertainment industry.


Nowadays, jewelry professionals also make use of CAD and 3D printing for rapidly prototyping complex designs that fit clients’ requirements and then produce a large batch of ready-to-cast pieces. With the help of digital tools, pieces with sharp details can be easily designed with consistency without worrying about messing with wax carving.

For most of the part, SLA rapid prototyping services are offered mainly for product designing, engineering and manufacturing various types of prototypes and moulds with perfection. So, whenever, you contact service providers, ask for what kind of products they provide their prototyping services and then proceed accordingly.
