# SLA
**SLA (Stereolithography)>**
A 3D printing method that uses a laser to cure layers of a liquid photopolymer resin together. This is often used to create high-quality, accurate prints with smooth surfaces and intricate details. Using an SLA 3D printing gives a versatile range of materials available.
Depending on the formulation and chemistry, some resins can be leveraged to produce pure silicone, polyurethane, or ceramic parts. Resin 3D printing also offers the broadest spectrum of biocompatible materials, opening up doors in end-use products, medical equipment, 3D printing at the point of care, and medical procedure innovation.
**How Does SLA 3D Printing Work? >**
SLA 3D printing uses a light source to cure liquid resin into three-dimensional objects by exposing a vat or tank of resin to a light source, which hardens it

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://www.ftcwiki.org/manufacturing-and-assembly/additive-manufacturing/3d-printing/sla.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
