The 3D printer from the Czech company Prusa is well-known among 3D printing enthusiasts. The device is based on a 32-bit motherboard and supports Input Shaper and Pressure Advance technologies, which reduce printing time by up to 70% compared to the MK3 printer without losing quality. The dimensions of the printer's working area are 250x210x220mm, and the entire structure is 500x550x400mm. The device is fully assembled and ready to use right out of the box.

Improved speed
The printer’s software uses Input Shaper and Pressure Advance technologies to eliminate vibration during printing and predict filament flow. This results in up to 70% less printing time than the MK3. It took her less than 20 minutes to print the Benchy model – see the manufacturer’s video. In addition, even at this speed, the printer is very quiet.
Exceptional print quality
The durable construction and new precision 0.9° Trinamic 2130 stepper motors in the X and Y axes reduce vertical waviness in prints (Vertical Fine Artifact). In addition, the Z axis has thicker 10mm rods. The result of these improvements is very good quality of the resulting models, even when using complex filaments.
New extruder
The innovative Nextruder direct extruder has many new features, and the LoveBoard support board inside ensures quick and easy replacement of parts such as thermistor, fan or heater. In addition, the Nextruder uses quick-change nozzles and has a Hall sensor that detects the end of the filament.
Perfect first layer
Getting a perfectly flat bed is a challenge for 3D printers. Fortunately, the Prusa MK4 head has a strain gauge sensor that performs this process automatically. The tip touches the bed and moves over a grid of measurement points, measuring the distance and calculating the correct offset. The result is a perfect first layer on any surface, without the need for manual adjustments.
Prusa Connect
The MK4 printer is fully supported by Prusa Connect, a platform that allows you to control the device over the Internet. Each connected printer has its own desktop from which you can control its operation. For increased security, the connection between the platform and the printer is encrypted.
User-friendly interface
The printer's screen has an easy-to-use interface that displays model thumbnails and allows you to control the printing process. Just below the screen is a programmable RGB LED strip that indicates the printer's current status using different colors.
