### Information

The **Original Prusa MK4S 3D printer**, better known as the **Prusa MK4S** or simply **Prusa Printers**, are a collection of **9** fused deposition modeling (FDM) 3D printers that act as the standard 3D printer at the AMS. These printers serve the majority of visitors at the AMS through our **Regular 3D Print Queue** and are highly versatile for all sorts of projects from fun decorative items to strong engineering parts.

Prusa printers can print a variety of different materials, but the AMS exclusively uses PETG on the Mk4Ss. The printers are outfitted with large 0.6mm nozzles, so prints are extra-strong, though make sure to [design for manufacturing](https://gtae.gitbook.io/ams/info/3dp-info/design-for-3d-printing) and reduce the amount of support.

For any prints going on the Prusas, a mentor will slice an STL file for you through a program called PrusaSlicer.
