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

As stated on our website: Prusa3D, if you purchase an assembled i3 printer, we offer a 10% discount on your subsequent purchases of assembled i3 printers and on selected filaments. If you choose to purchase your printer as a kit, we offer a 5% discount on selected filaments. In both cases, the discount is automatically activated in your account as soon as your first kit or printer is shipped.

Can I have my printers frame signed by Jo?

Josef can sign the frame, but please know it can delay the expedition for over a month. He is very busy these days. If it's OK with you, you can ask for the signature in an email or via Live Chat.

What are the printer dimensions?

The dimensions are (W×L×H or X×Y×Z):

  • An assembled Mini printer has 12.6 × 13 × 15 inch / 320 × 330 × 380 mm and 5 kg
  • Mini print area: 7×7×7 inch / 180 × 180 × 180 mm

 

  • An assembled SL1 printer has 8.7 × 9.45 × 16.3 inch / 220 × 240 × 415 mm and 11 kg
  • SL1 print area: 4.7 × 2.6 × 5.9 inch / 120 × 68 × 150 mm

 

  • An assembled i3 (MK2/3) printer itself has 16.5 × 16.5 × 15 inches / 420 × 420 × 380 mm and 7 kg
  • MK3/S print area: 9.8 × 8.2 × 8.2 inches / 250 × 210 × 210 mm
Keep in mind that the mini and all i3 printers need some more space when in use. Especially in front of and behind them, as the heatbed is moving outside their footprint. Count with 19.7 × 21.5 × 21.5 inches / 500 × 550 × 450 mm (400 × 450 × 450 mm for the Mini), without the spool or MMU.
If you are building an enclosure, you can add even more space in every direction, for better access and manipulation. For the MMU, add 150 mm / 6 in, in height, and think about where to put the 5 spools (behind the printer or above).

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 diameter 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. 

This article studies the accuracy of FDM printing in more detail.

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
  • 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, at 26 °C (room temperature), is 80 W when printing generic PLA and 120 W when printing generic ABS.
