Weve designed the UI to beeasy to use even for complete beginners, yetits reliable performance also makes it aperfect fit for professional workshops.Getting started is super easy: simply take the MK4S out of the box, plug it in, perform a quick calibration, and start printing in 15 minutes!World-Class Print SpeedAsToms Hardwareputs it: The Prusa MK4S is pretty darn fast. Itsubstantially cuts print timesthanks to the new cooling fan with a powerful turbine and 360 air delivery, as well as the high-flow nozzle that allows for maximized filament flow. Combined withoptimized firmware and print profiles,the results are both quick and flawless.Perfect Dimensional AccuracyYour creations should turn out precisely as designed, especially when they require a perfect fit.The MK4S ensures that by delivering exceptionally accurate prints.See the accuracy comparison measured using a CT scan:360 Cooling Print without SupportsReduce the need for supports and print quicker with less material! Thanks to the 360 cooling, the MK4S allows you toprint overhangs of up to 75 without supports,significantly cutting down on print costs and time. This also simplifies printing flexible materials like TPU, where removing supports is often a challenge.Perfect Surface FinishYour models turn outsmooth and a joy to look at,as the MK4S print profiles prioritize perfect surface finishes. You can adjust print layer height tomatch your desired level of detailand print everything from super intricate models (with the 0.25mm nozzle) to larger objects, where details matter less.32-bit xBuddy MainboardOur new xBuddy board is a 32-bit STM32-powered mainboard with many great features. It hasseveral unique hardware-based safety protection systems, communicates with four thermistors, has all importantports (Ethernet, Wi-Fi, works with USB-A flash drives)and more. The entire board was designed, manufactured, and tested in-house.Color LCD screen and simple UIMK4Ss displaysupports G-code thumbnails, QR codes and other elementsthat make using the printer so much easier. We alsoredesigned many of the existing menusand added a customizable footer panel. Directly under the LCD, there is anRGB status bar to signalize the current status of the printer. Next to the LCD, theres a USB-A port for standard USB flash drives.Slice with PrusaSlicerOur internally developed multiplatform slicer comes within-house made and fully tested profilesfor all of our 3D printers and a wide range of filaments. With built-in tools, such asorganic supports, cutting, automated object distribution, ironingand many others, you will turn your 3D models into print files in no time!Prusa Connect and Connectivity OptionsMK4 is, along our other 3D printers,fully supported by Prusa Connect, which allows you to control the printer via internet. You candrag-and-drop G-Codesinto the browser window to upload print files first into the cloud (each user gets 2 GB for free) and then transfer it into the printers USB storage andstart the print remotely.

Cosmetic damage, which includes, but is not limited to, scratches, dents, cracks, or other aesthetic damage, is also not covered. Only sheets defective upon delivery are covered by the warranty.Add-onsThey are sold separately, as an additional itemReady for multi-color printing with MMU3MK4 can be enhanced by an optional add-on that allows your single-extruder printer toprint with up to 5 colors (materials) at the same time. The MMU3 contains five filament insertion points. Load the five colors of your choice,slice the object with MMU3 profile in PrusaSlicer and start the print. The system automatically selects filament using the selector, loads it into the Nextruder and the MK4 starts printing. When its time to change the color or material, it also happens automatically.The MMU3 is the latest edition of Multi Material printing device by Prusa Research.The firmware has been rewritten completely, we have redesigned the plastic parts, added more robust metal parts, improved the electronics and updated the filament buffer. All of these changes have improved the reliability and user comfort to levels where MMU has never been before.Ask to consultas@ to get aquoteEnclosure availableMK4S is fully compatible with the Original Prusa Enclosure.If you want toprint more advanced technical materialson your MK4S, youll find the Enclosure really handy.
