What is SLA 3D Printing?

SLA 3D printing, Stereolithography, is a type of additive manufacturing technology that uses a laser to cure liquid resin into hardened plastic, layer by layer. It’s one of the earliest 3D printing methods and is known for producing highly detailed and smooth-surfaced parts.

The process works by aiming a UV laser at a vat of photopolymer resin. The laser traces a pattern on the surface of the liquid, solidifying it where it hits. The build platform then moves slightly, and the next layer is traced and cured. This is repeated until the object is fully formed.

SLA is commonly used for:

  • Tradeshow models.
  • High resolution applications.
  • Dental & medical models.
  • Prototypes with fine details.

Its main advantages are high precision, smooth surface finish, and the ability to produce complex geometries. A wide selection of materials with different properties are used within resin 3D printing.

Stereolithography 3D Printing FAQs

SLA 3D printing stands out for its high precision and smooth surface finish, making it ideal for detailed prototypes and aesthetic models. Unlike SLS, which uses powdered materials for durable, functional parts, SLA’s photopolymer resins are less robust but offer excellent detail and clarity. LCD, similar to SLA, is faster but may show more visible layer lines. Overall, SLA excels in applications where fine detail and smooth surfaces are critical.

Stereolithography uses photopolymer resins which can have properties such as having a high heat resistance, transparent, ceramic-like and more.

See above for a list of SLA 3D printing materials we offer, you can also request them through emailing us at info@ame-3d.co.uk.

Industries like dental, jewelry, medical, and consumer goods benefit greatly from SLA’s precision and aesthetic qualities, often using it for prototyping, modeling, and detailed custom parts.

Large-format SLA 3D printing refers to the use of stereolithography (SLA) technology to create oversized, high-resolution parts and prototypes. Traditional SLA 3D printing is often associated with smaller parts due to its reliance on resin tanks and the size of available platforms. However, large-format SLA expands this capability, allowing for the production of objects without the need to be split and rejoined.

Our largest platform size is 800x800x550mm.

Turnaround time varies, but small to medium parts can be printed within 24–48 hours, depending on complexity and post-processing needs.

We have created a design guide with specifications for our 3D printing, vacuum casting and reaction injection moulding technologies.
