The Original Prusa MK4 3D Printer is the ultimate machine for enthusiasts and professionals who demand superior quality prints with every project.
The Original Prusa MK4 3D Printer delivers exceptional print quality with its high-resolution Printing capabilities, smooth layering, and accurate dimensions. The printer is designed to be easy to calibrate, with an intuitive calibration process that ensures consistent and accurate Printing. The Original Prusa MK4 3D Printers offers a dual extrusion upgrade, allowing users to print with two different colors or materials simultaneously. The Original Prusa MK4 3D Printer has received outstanding reviews and testimonials from users worldwide. Customers have praised the printer's high-quality prints, ease of use, and reliable performance.
The MK4 printer can eliminate resonance in prints and anticipate the flow of the filament thanks to our own implementation of Input Shaper and Pressure Advance technologies in the firmware. As a result, print times can be reduced by up to 70% when compared to MK3. Check out the Benchy video that is under 20 minutes to see how quiet the printer is even at these speeds. Read the blog post for more information on the upcoming firmware update that will support high-speed Printing.
The MK4 can automatically lay down a first layer that is flawlessly smooth and consistent without any user input because of the precise Loadcell sensor. The printer taps the sheet with the nozzle at the start of a print to measure the distance and then figures out the proper offsets. Every surface has a flawless first layer as a result, with no manual adjustments necessary.
Every 3D Printer has an extruder at its core. And this one is unique. The process of changing extruder components on the majority of 3D Printers today is fairly challenging. All of the components, including fans, heaters, thermistors, and other components, are directly connected to the new connector break-out board inside the Nextruder. It only takes a minute to swap anything out if you need to.
A 32-bit STM32 mainboard running our new xBuddy software, it has a tonne of great features. Additionally, it communicates with four thermistors, has all necessary ports (Ethernet, Wi-Fi, and supports USB-A flash drives), and has a number of special hardware-based safety protection systems. The entire board was created, produced, and tested within the company.
The MK4 has new precise 0.9° stepper motors (0.9° / step; low inductance) on the X and Y axes that help eliminate Vertical Fine Artifacts on prints as well as redesigned, more durable plastic parts. Additionally, the Z-axis has thicker 10mm rods. As a result, prints now appear more impressive than ever, and Printing with "problematic" filaments like Flex is simple.
The Nextruder's body has two quick-release thumbscrews that hold the nozzle in place, making it simpler than ever to switch out the nozzle. The MK4 uses specialised nozzles and an all-metal filament guide (there are no PTFE tubes anywhere), which increases the printer's overall dependability. There is an easy Nextruder to V6 adapter available.
G-code thumbnails, QR codes, and other features that make using the printer so much simpler are supported by the MK4's display. We also added a customizable footer panel and redesigned a number of the existing menus. An RGB status bar directly beneath the LCD displays the printer's current status. There is a USB-A port for common USB flash drives right next to the LCD.
For all of our 3D Printers and a variety of filaments, our in-house created and thoroughly tested multiplatform slicer comes with profiles. You can quickly convert your 3D models into print files using built-in tools like cutting, automated object distribution, organic supports, ironing, and many others.
The MK4 is completely compatible with many different kinds of materials. The MK4 can print anything you need, whether you want to print something for fun out of PLA and flexible materials or you need to make durable prototypes out of PETG, ASA, Polycarbonate, and Polypropylene.
Prusa Connect, which enables you to control the printer online, fully supports MK4 and our other 3D Printers. To upload print files into the cloud (each user gets 2 GB for free), transfer them to the printer's USB storage, and then start the print remotely, you can drag and drop G-Codes into the browser window. Every exchange is encrypted.
An optional add-on for MK4 gives your single-extruder printer the ability to print with up to five different colours (materials) simultaneously. Five filament insertion points are present on the MMU3. Choose five colours to load, slice the object using PrusaSlicer's MMU3 profile, and then begin Printing. The Nextruder is loaded with the chosen filament by the system, which then automatically selects it, and the MK4 begins Printing. It also happens on its own when it's time to change the colour or material. The most recent model of Prusa Research's Multi Material Printing system is called MMU3. We completely re - write the firmware, redesign the plastic components, add more durable metal components, upgrade the electronics, and update the filament buffer. All of these modifications have raised MMU's reliability and user comfort to previously unheard-of heights.
The MK4 enclosure works flawlessly with the original Prusa enclosure. The Enclosure will come in very handy if you want to print more complex technical materials on your MK4. It makes the printer even quieter, stabilises the environment around the printer, and gets rid of smells and draughts.
