Supercharge your MK3S and MK3S+!

With the introduction of the MK4, we were looking for ways to bring its features to our proven workhorse, and the MK3.5 upgrade is the answer. It’s the easiest and most affordable option to print two times faster and expand the capabilities of your MK3S/+ 3D printer!

Enjoy benefits such as super-fast printing with the addition of Input Shaper, sending files wirelessly to your machine without using Raspberry Pi, and navigating the printer’s menus faster than ever before with the new large LCD. The upgrade is straightforward to install and with our detailed assembly guide and 3D printing handbook, you’ll be up to speed in no time!

High-speed printing with ease

As a part of the upgrade package, you will receive our new 32-bit embedded xBuddy to expand your 3D printer’s capabilities. The addition of Input Shaper and Pressure Advance brings a massive boost to your MK3S/+, allowing you to print more than twice as fast and with the same level of quality. The prints that would be otherwise running the entire night can be finished in just a few hours.
 

Prusa Connect and easy networking

With the MK3.5 upgrade, you also receive an easy way to connect your printer to your network - both wired and wireless. Add the MK3.5 to Prusa Connect, our internally developed remote print management solution, and start sending print files to your printer without the need to deal with USB drives. G-code streaming enables you to start printing mere seconds after you upload the file to the Prusa Connect cloud. However, Prusa Connect can do even more. Check out our article to learn all about it!

Plenty of quality-of-life improvements

It’s time to replace the old segmented LCD with a brand new one. This 3.5’’ color LCD gives you much better control over your printer. See print file previews, read detailed instructions, or scan QR codes - using the printer is now much more convenient. With the new electronics and the new LCD, you can now use standard USB flash drives for storing G-codes, and you can also use a USB drive to flash new firmware (but you can also do it remotely via Prusa Connect). You can customize which information is displayed at all times in the footer of the LCD screen.

Easy to install

The MK3.5 upgrade is easy to install - we’re providing detailed assembly instructions in seven languages and an updated 3D printing handbook to get you started. You don’t have to worry about getting stuck. Everything has been thoroughly tested in-house. You’ll start printing in no time!

Ready for multi-color printing with MMU3

MK3.5 can be enhanced by an optional add-on that allows your single-extruder printer to print 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 Extruder and the MK3.5 starts printing. When it’s 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.

To get MMU3 for your MK3.5 printer, you can choose from the following options:

• If this is your first multi-material, get the full MMU3 kit including MMU unit, buffer and spools.
• If you already have the MMU2S unit, get the MMU2S to MMU3 upgrade for MK3.5.
• If you currently own the MK3S+ with MMU3, get this MK3.5 upgrade and the MMU3 cable.
