Common Questions

What is the Difference Between SLA and SLS Materials?

Formlabs currently has two 3D printer technologies on the market: SLA and SLS.

For each 3D printer technology there is a corresponding material science; SLA 3D printers use resins, while SLS 3D printers use nylon powder.

For Formlabs 3D printers, resins are used for the Form lineup. This means Form 3+ / Form 3B+ and Form 3L / Form 3BL use resins materials for their 3D printing.

On the other hand, nylon powders are used for Formlabs Fuse 3D printers. This currently includes the Fuse 1 and Fuse 1+ 30W.

How Does Each 3D Printing Technology Work?

SLA 3D printers cure resin with laser(s) to harden each layer of a print. SLS 3D printers also work in layers but instead use laser(s) to sinter (or "Fuse") each layer of nylon powder.

Each technology has advantges for certain use-cases which we talk about more on the 3D Printers Collection Page.
