FAQ - Frequently Asked Questions

How do I get the kit or assembled printer owner discount?

As stated on our website Prusa3D, if you purchase an assembled MK4S printer, we offer a 10% discount on your upcoming five subsequent purchases of an assembled printer of the same type and on 30 spools of selected filaments per year. Note that this does not apply to any printer other than the MK4S. If you choose to purchase your printer as a kit, we offer a 5% discount on 30 spools of selected filaments per year. In both cases, the discount is automatically applied to your account when your first kit or printer ships.

Can I have my printer signed by Jo?

Yes, Josef can sign the machined aluminum card, which can then be attached to the printer at your preferred location, but please note it can delay the expedition by over a month. He is very busy these days. If it's OK with you, you can ask for the signature via email or Live Chat.

What is the printing precision/tolerance of the Original Prusa?

According to our testing, the precision tolerance of a well-assembled Original Prusa printer is 0,1 mm on the Z-axis and 0,3 mm on X and Y. It can be as little as 0,05 mm on all axes, after making additional calibrations such as the Extrusion multiplier calibration and Extruder linearity correction.

However, please note that the material is also relevant: it can shrink while cooling down, and low-quality filaments with uneven diameters will cause uneven extrusion. The optimization of the model for 3D printing (overhangs, etc.) is also important. Our printers are tested even for the 0.25 mm nozzle, which is more precise compared to the standard/stock nozzle with a 0.4 mm diameter.

What tools do I need when working with my Original Prusa?

All necessary tools (pliers, screwdriver, hex keys, wrenches…) are included in the package. If you are wondering what else you could need, here is a list of some nice-to-have things:

• 3.5'' side-cutter/flush-cutter pliers
• White permanent marker
• Compressed air
• A big bottle of IPA 91% to clean the sheet
• Acetone (only with the smooth sheet)

What is the life expectancy of the printer?

According to our testing, the average maintenance interval of our printers is around 800 print hours. When it needs to be serviced, most frequently, it’s the nozzle that needs to be changed, and then it can continue printing for many hundreds of hours more.

The ideal air temperature is from 20 - 30 °C (68 - 86 °F) and the ideal air humidity is 25 %.

What is the power consumption of a PRUSA printer?

The average power consumption that we have measured on an MK-series printer, at 26 °C (room temperature), is 80 W when printing generic PLA and 120 W when printing generic ABS.
