Start with manufacturer guidance for a specific product and printer context. Every card states its scope; none is presented as a universal material profile.
Confirm the spool label and current slicer preset before printing. Color, additives, nozzle size, sheet, enclosure conditions, and product revisions can change the appropriate values.
Manufacturer material guidance explicitly marked relevant for the MK4 family, shown for the original MK4 stock 0.4 mm nozzle. It is not a universal PLA profile.
Nozzle
215 °C first layer; 210 °C later
Bed
60 °C
Build surface
Smooth or satin PEI sheet
• The Prusa material guide is marked relevant for the MK4 family; the original MK4 ships with a 0.4 mm nozzle.
Manufacturer material guidance explicitly marked relevant for the MK4 family, shown for the original MK4 stock 0.4 mm nozzle. It is not a universal PETG profile.
Nozzle
230 °C first layer; 240 °C later
Bed
85 °C first layer; 90 °C later
Build surface
Textured or satin PEI sheet
• PETG can adhere too strongly to smooth PEI; follow Prusa's separation guidance.
Manufacturer material guidance explicitly marked relevant for the MK4 family, shown for the original MK4 stock 0.4 mm nozzle. It is not a universal ABS profile.
Nozzle
255 °C
Bed
100 °C; guide notes 80-110 °C by object size
Build surface
PEI sheet with glue separator
• Use a stable warm enclosure for larger parts and provide ventilation.
Manufacturer material guidance explicitly marked relevant for the MK4 family, shown for the original MK4 stock 0.4 mm nozzle. It is not a universal ASA profile.
Nozzle
260 °C

• Use an enclosure for larger parts, avoid drafts, and provide ventilation.
Manufacturer material guidance explicitly marked relevant for the MK4 family, shown for the original MK4 stock 0.4 mm nozzle. It is not a universal TPU profile.
Nozzle
230-245 °C, depending on hardness and brand
Bed
60-75 °C, depending on object size
Build surface
Powder-coated sheet or separator
• Use the product-matched PrusaSlicer profile; the guide describes about 20 mm/s as typical and 30-40 mm/s as a recommended maximum.
