Material compatibility
What materials the Prusa Research MK4S can print
This comes from four facts on its spec sheet: the nozzle reaches 290 °C, the bed 120 °C, and the machine is open-frame with a direct-drive extruder. Those four facts decide most of the list: nozzle temperature sets the ceiling on what you can melt, the bed decides whether the first layer sticks, the enclosure keeps large parts from warping, and the extruder type rules flexibles. We don't test the machine — this is guidance derived from verified data, not a guarantee.
In short: it prints PLA, PETG, TPU (flexible) without a fight, and it can reach ABS, ASA, Nylon (PA), Policarbonato (PC) with conditions — the detail for each is below.
| Material | Prints it? | Why |
|---|---|---|
| PLA | Yes | Yes. PLA has no special needs: any FDM printer like the MK4S prints it out of the box. |
| PETG | Yes | Yes. With a nozzle up to 290 °C and a bed up to 120 °C it comfortably meets PETG's needs. |
| TPU (flexible) | Yes | Yes. It has a direct-drive extruder, ideal for flexibles; prints TPU well (go slow). |
| ABS | With caveats | With caveats. It reaches 290 °C, but it's open-frame: ABS can warp and ventilation is advised. Doable in a draft-free spot or by adding an enclosure. |
| ASA | With caveats | With caveats. It reaches 290 °C, but it's open-frame: ASA can warp and ventilation is advised. Doable in a draft-free spot or by adding an enclosure. |
| Nylon (PA) | With caveats | With caveats. It reaches 290 °C but is open-frame; Nylon warps in drafts and absorbs moisture. Enclosure + drying almost mandatory. For carbon-fibre variants, use a hardened-steel nozzle. |
| Policarbonato (PC) | With caveats | With caveats. It has the temperature (290 °C) but is open-frame; PC warps badly without an enclosure. Only with one added. For carbon-fibre variants, use a hardened-steel nozzle. |
