Prusa Research Original Prusa i3 MK3 overview
The Original Prusa i3 MK3 is a desktop 3D printer made by Prusa Research, formerly known as Prusa3D. Prusa Research is led by Josef Prusa, the original creator of the Prusa i3 3D printer model.
The previous version of this 3D printer is the Original Prusa i3 MK2, one of the top-rated machines on the market. The MK2 won four awards, and with all its upgrades the MK3 is bound to encounter the same success.
This workhorse 3D printer is faster, sturdier and more silent than the MK2. It offers radial cooling, for better 3D print quality.
Prusa Research, in collaboration with Ultimachine, developed a new and more advanced motherboard- the EINSY RAMBo. It can monitor and detect blown fuses, a useful feature for debugging. Also, a Raspberry Pi Zero W can easily fit onto the motherboard for OctoPrint, allowing for SD card and Wi-Fi connectivity.
Furthermore, the Original Prusa i3 MK3 features Trinamic2130 drivers that allow the 3D printer to be more silent and to detect shifted layers (and fix it).
Prusa i3 MK3 vs Prusa i3 MK2: main upgrades
What’s new with the Original Prusa i3 MK3:
- Magnetic bed with swappable steel sheets:
- For easy and quick 3D print removal.
- The flexible steel sheets have a PEI powder coating.
- The print bed can reach up to 100°C.
- Optical filament sensor:
- Enables automatic filament loading.
- Lets the user know when the filament is running out and pauses the 3D print.
- Detects filament jams and stops the 3D printing process.
- Power panic: if there is a power outage, the MK3 will go back to where it last left off when the power is back. This feature works without batteries.
- Sensing fans and Noctua: for more silence when 3D printing. Also, cooling from both sides of the extruder increases the 3D printer’s overhang performance.
- New Y axis: gives the 3D printer a smoother look and a sturdier frame.
- Bondtech extruder: dual gears ensure a reliable grip on the filament to prevent filament from slipping. The extruder can reach up to 300°C.
