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.
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.
The dimensions are (W×L×H or X×Y×Z):
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.
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:
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 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.
