Introduction
Diving into the realm of resin 3D printing, the Original Prusa SL1S SPEED from Prusa Research offers precision and speed that are often sought after by professionals and hobbyists alike. While most of Prusa Research’s reputation is built around their outstanding FFF (Fused Filament Fabrication) printers, the SL1S SPEED is a delightful venture into the MSLA (Masked Stereolithography) technology. MSLA is a subtype of SLA where a light source is masked by an LCD panel to cure photopolymer resin layer by layer.
This blog post will guide you through the features, specifications, and capabilities of the Original Prusa SL1S SPEED, a machine that stands out for its rapid printing and highly detailed output. We’ll compare it with other printers in the Prusa lineup, delve into its specialized spec sheet, and provide insights into the types of resin it can utilize.
About the Printer and Brand
The Czech-based Prusa Research has grown beyond its roots in the FFF world to embrace the high-resolution capabilities of resin printing with the Original Prusa SL1S SPEED. With a build volume of 1.52 liters, it targets a niche that requires exceptional detail and a smooth finish, hallmarks of MSLA technology. A monochrome LCD provides the light source for rapid curing of each layer, while the high-resolution XY axis of 49,6 microns ensures every detail of your design is captured.
The Original Prusa SL1S SPEED, with its compact, enclosed design, provides a controlled environment for resin prints, free from external variables that could affect print quality. The added benefit of an enclosed build chamber also helps in regulating temperature and reducing odors, factors that can be crucial when working with resin.

Filaments Possible to Print
Given the Original Prusa SL1S SPEED’s technology, we’ll specify resins that are suitable for printing rather than filaments:
- General-purpose resins
- Dental resins
- Castable resins
- Tough / durable resins
- High-temperature resins
- Flexible resins
Filaments Possible but Not Recommended
For the Prusa SL1S SPEED, which uses resin, there aren’t specific materials that are possible but not recommended. However, always ensure that the resin used is compatible with the 405 nm wavelength used by the printer’s light source.
FAQ´s
