3D Printing on the Prusa MK4S

By Admin, 20/08/2026 · 1 min read

A beginner workflow for preparing a Prusa MK4S print in PrusaSlicer, loading filament, checking the first layer and removing the part.

3D Printing

Use the Prusa MK4S by matching the PrusaSlicer profile and filament to the physical printer, then check the first layer before continuing the job.

Before printing

Prepare the machine and material

Use the printer profile, plate, nozzle and filament that match the physical setup.

1

Choose the printer profile

In PrusaSlicer, select the Prusa MK4S profile and confirm the nozzle size and build-sheet type.

2

Prepare the sheet

Fit the clean spring-steel sheet and select the matching sheet profile before slicing.

3

Load the filament

Load the filament through the extruder path and confirm that it feeds cleanly from the spool.

4

Slice and preview

Set the material profile, slice the model and inspect supports, walls, infill and the first layer.

5

Start and check

Transfer the job using the printer's available connection method and watch the first layer for gaps, lifting or debris.

6

Cool and remove

Wait for the part and sheet to cool, then flex the sheet gently to release the print.

The MK4S uses its own printer and sheet profiles, so do not reuse a Bambu profile or plate setting.

Keep the sheet clean and handle it by the edges where possible to reduce adhesion problems.

For ABS, ASA or other enclosed-printer materials, follow the material maker's ventilation and enclosure guidance.
