The Original Prusa i3 MK3S+ is the latest version of the award-winning 3D printers. Prusa Research has upgraded the MK3S with a brand new SuperPINDA probe for improved first layer calibration, added high-quality bearings and various useful design tweaks to make the printer easier to assemble and maintain. The MK3S+ includes all the proven features of the previous models, including the heatbed with removable PEI spring steel print sheets, automatic Mesh Bed Leveling, filament sensor, power loss recovery (power panic) and safety features. And it is still as silent as ever!


Main Features

 

SuperPinda Probe

SuperPINDA probe features a hiqh-quality sensor for a fully-automatic Mesh Bed Leveling process. Before every print, the MK3S+ probes the bed in several places and creates a virtual heightmap of the print area. This process ensures that the first layer will always be spot on!

Bearings & more

The MK3S+ features a new set of metal clips for the  bearings on the Y-axis. The belt tensioning mechanism on the X-axis was reworked and the X-end plastic parts reinforced. The filament path in the extruder was altered for better support of flexible filaments.

Removable Print Sheets

Spring steel sheets are easy to maintain and make removing the printed object from the print surface a breeze. Prusa Research offer three types of print surface: smooth, textured and satin to cover all your needs when printing from a wide range of different materials - most of which do not require any special separation layers or surface preparation.

High-Quality Parts

The MK3S+ features an aluminum extrusion Y-axis assembly. Thanks to the milled frame, the MK3S+ is stable, rigid, and easy to assemble. Combined with their internally developed extruder featuring Bondtech gears and the E3D V6 hotend, the MK3S+ can print high-quality objects up to 210 mm in height.

Power Loss Recovery

Are you afraid of a blackout ruining your 48-hour print? Worry no more - the MK3S+ can deal with that! The printer can fully recover from the loss of power and continue printing exactly where it left off. It detects power interruptions and shuts down the heatbed and extruder heating, and saves the last known location.

Filament Sensor

The MK3S+ further enhances the reworked extruder from the MK3S. The built-in filament sensor uses a reliable trigger system, which detects whether a strand of filament is inserted into the extruder. It can detect any type and color of filament and is not susceptible to mechanical wear.

Mesh Bed Leveling

Thanks to the SuperPINDA probe, the MK3S+ can use the Mesh Bed Leveling process to compensate for microscopic imperfections of the print sheet, and inconsistencies caused by the assembly and stacking of the manufacturing tolerances of various parts. Achieving a great-looking first layer is quick and easy.

Slice with PrusaSlicer

Prusa Research has their internally developed multiplatform slicer with in-house made and fully tested profiles for all of our 3D printers and a wide range of filaments. With built-in tools, such as advanced support generation, cutting, automated object distribution, ironing and many others, you will turn your 3D models into print files in no time!

Support for a wide range of Materials

The MK3S+ is fully compatible with a wide range of various types of materials. No matter whether you want to print something for fun from PLA and flexible materials, or you need to produce durable prototypes from PETG, ASA, Polycarbonate and Polypropylene - the MK3S+ can handle them with ease.

Open-source Hardware & Firmware

Prusa Research develops firmware for all of their 3D printers and test every new version thoroughly before release. Ongoing development and regular updates ensure that their machines are packed with useful features, such as print sheet profiles, automated calibration, Mesh bed leveling, advanced diagnostics, remaining print time estimation, Octoprint support and more!

ADVANTAGES OF AN ASSEMBLED 3D PRINTER

Compared to the assembly kit, the assembled printer differs only in the form in which you receive it. The printer comes pre-assembled and tested right out of the box. To start your first print, simply plug it in, run the initial calibration, and you are good to go. It is an ideal choice for businesses and education where there is a need to start printing as soon as possible.

3

Built-in Safety Features

Original Prusa 3D printers are well-known for their reliability and safe operation. Every part of their printers is thoroughly tested in-house. The MK3S+ is equipped with three thermistors and comes with a custom-built high-quality Delta power supply. The printer can recognize issues with heating and stop operation to prevent damage.

4

Open-source and Community Friendly

All parts of their printer are open-source, which means they publish all source codes and blueprints online. The community around their products is huge and the feedback is overwhelmingly positive - don't believe us? Check out their Facebook groups and YouTube videos! There's so much to do with your 3D printer - buying it is just the beginning!

5

Ready for the Multi-Material Upgrade 2S

Multi Material Upgrade 2S is our unique add-on option for printing with up to 5 different filaments simultaneously. Multi-material could be your next step in the 3D printing world and the MK3S and MK3S+ are completely ready for the upgrade! MMU2S also allows you to print a soluble support interface

6

Upgradability

One of the most popular features of the Original Prusa i3 concept is upgradability. When you buy their 3D printer, in most cases you can upgrade it later to a newer version, so you don't need to buy a whole new model every two years like, for example, your phone or laptop. They also keep supporting their 3D printers with regular firmware updates that bring new features!


Ready to print settings

Prusa Research provides high quality print settings with the printer, so you don't have to dive into complex new programs the second you finish the build. You can start printing right away, and this gives you a great head start!

These settings are great for all kinds of objects, not just for a couple of prepared showpieces. After a while, when you're familiar with the printer, you can, of course, dive into tinkering ;-)

PrusaSlicer is a feature-rich, frequently updated tool that contains everything you need to export the perfect print files for your Original Prusa 3D printer. But of course, Prusa Research also have the settings for the third party slicers like Simplify3D, Cura, etc.

First time doing 3D printing .... Original PRUSA MK3S+

I am still putting it together ... a section each day. My friend David Byrne said the instructions are excellent and I agree ... being online they also make user comments available .I still have a biunch of assembly but expect I can do it even though it is the more difficult stuff. Then calibration items then I can see about printing something . I am getting my neighbors keyed up with their 2D projects ... I plan to print a telephone sign for my K2 London telephone booth ...

Printers are a dream

We have several Prusa printers in our library system. We love them. Moving from aging Lulzbots to Prusa has been so incredible. Ease of setup and quality are just a couple of the wonderful things about them. The slicer is so amazing at the speed in which it opens. Heating times are so much faster than the Lulzbots. I love them so much I bought one for myself. We just pruchased 6 more to replace the remainder of our printers. Soon we will have Prusas in all 14 branches.
