Stereolithography (SLA) Process
Stereolithography (SLA) is an additive manufacturing process that uses a laser to cure a photosensitive resin and create a three-dimensional (3D) object. SLA 3D printing is one of the most accurate and precise additive manufacturing processes available, making it ideal for creating prototypes and small-batch production runs.
The SLA process begins by curing a layer of resin with a laser. The layer is then lowered into the vat of uncured resin and cured again. This process is repeated until the entire object has been built up layer by layer. One of the benefits of SLA 3D printing is that it can create very intricate and detailed objects that would be difficult or impossible to create with traditional manufacturing methods.
SLA 3D printers are available in both desktop and industrial sizes, making them accessible to everyone from individual designers to large manufacturers. If you’re looking for a high-quality, accurate, and reliable 3D printing technology, stereolithography is an excellent option.

Our SLA Manufacturing Standards
We manufacture your parts according to strict manufacturing standards. Verification of these requirements is included in the inspection report we provide with each order.
- Desktop SLA : Dimensional accuracy of ± 0.5% down to ± 0.5 mm (± 0.006").
- Industrial SLA : Dimensional accuracy of ± 0.25%, lower limit: ± 0.25 mm (±0.005").
- Parts are cured to material specifications before being shipped to you.
- Hollow sections can be drained of excess resin when necessary.
- All support material is removed, and the new nibs are sanded smooth.
Overview: What is SLA 3D printing?
SLA 3D printing is a type of 3D printing that uses a laser to cure photopolymer resin into the required shape. It is one of the most popular 3D printing technologies due to its accuracy and high resolution.
What is the difference between SLA and FDM?
The main difference between SLA and FDM is that:
- SLA produces parts with greater accuracy and finish, while FDM is better for larger prints;
- SLA has a higher price per part, while FDM is less expensive;
- SLA prints using resin, while FDM prints with plastic filament;
- SLA typically has a slower printing speed than FDM.
What are the benefits of SLA 3D printing?
Accuracy is important for creating objects that need to fit together precisely or for applications that require high tolerances. With SLA 3D printing, objects can be created with a much higher degree of accuracy than with other methods such as FDM printing.
Surface finish is also important for many objects. While FDM printing can create surfaces that are smooth enough for many applications, SLA 3D printing produces even smoother surfaces. This is due to the fact that SLA printers use ultraviolet light to solidify the resin, which results in a higher quality surface finish.
Finally, SLA 3D printing is stronger than other forms of 3D printing. This is because the object is built up in layers, which allows for more support material to be used. This makes SLA prints far less likely to break or crack than other types of prints.
Frequently Asked Questions
There are a few key challenges when it comes to using SLA for 3D printing:
- The need for accurate and consistent scans
- The need for stable resin levels
- Limited build volume
The print-head on an SLA printer traces out a cross-section of the desired object on to a bath of liquid resin. A UV laser then hardens the resin in that spot, forming the first layer of the object. The printer then lowers the platform by a fraction of a millimeter and repeats the process, slowly building up the object one layer at a time.
The three primary materials used in stereolithography 3D printing are photopolymers, resins and metals. Photopolymers are the most common type of material used in SLA 3D printing. They are made up of molecules that react to light, hardening when exposed to ultraviolet (UV) radiation. This makes them ideal for 3D printing as it allows for the creation of intricate designs with fine details.
In recent years, the technology of selective laser sintering (SLS) printing has undergone rapid development, and this type of 3D printing technology is now commonly used in industrial production.
The selective laser melting process uses a high-energy beam to fuse powdered material, layer by layer, to create a three-dimensional shape. The build chamber is filled with a bed of powder that is spread evenly across the build platform. An energy-intensive laser then selectively fuses areas of powder according to your digital design.
