You have asked for it. We have always listened. Even though almost all the components are needed to be replaced, it will be possible to upgrade from MK2/S to MK3S.
If you don't need a full MK3S upgrade, you can use our upgrade to MK2.5S. It offers most of the important new features of MK3S and is significantly cheaper.
This upgrade kit is no longer available. Production has been stopped on 31.12.2020.
The leadtime for new orders is 3-4 weeks.

Continuous development of the Original Prusa i3 MK3 and MK3S leads us to the enhanced and improved Original Prusa i3 MK3S+ released on November 24. 2020 and announced on PrusaPrinters.org
The previous sensor didn’t work well with some specific filaments. The new sensor is using the optical sensor which is triggered by a simple mechanical lever. This sensor doesn’t care about the optical properties of the filament and cannot die because of mechanical wear.
Thanks to completely reworked extruder changing the nozzle or PTFE tube is easier than ever before. As a bonus, the nozzle and the extruder motor is much closer to the X axis, this means less resonance and better prints too. MK3S is also better for printing from flexible materials.
MK3S+ includes all the cumulative upgrades from the entire life cycle of the MK3 like genuine Gates belts, textile sleeves, a new Einsy case for easier Raspberry Pi connection, an anti-rust coating on smooth PEI sheets and, of course, dozens of firmware and plastic parts enhancements.
The most significant features of Original Prusa i3 MK3S+
The new MK52 Magnetic Heatbed holds a replaceable alloy spring steel sheet with a PEI surface. You can choose between two types of sheets - smooth PEI sheet (default option) and textured powder coated PEI.
With the MK3S+ we are introducing the reworked Y axis from
Thanks to the new Trinamic2130 drivers and Noctua fan, the MK3S+ is extremely quiet in the stealth mode. But the MK3S+ is quieter than 99 % of the available printers, even in the Normal mode. In normal mode, we have also increased the travel speed. Now you can achieve up to 200 mm/s!
MK3S has two new thermistors. The first one measures ambient temperature on the electronics, preventing MINTEMP errors in rooms with 15°C or less. The second one is embedded in the new P.I.N.D.A. 2 probe to compensate for temperature drift. So the first layer will always be spot on!
E3D V6 is market-leading all metal hotend well known for its high-temperature performance. The MK3S+ utilizes a
The extruder has now upgraded with Bondtech drive gear. It grips the filament from both sides, increasing the push force and making the printer more reliable. This is useful
With MK3S+ we are introducing a completely reworked extruder with a new filament sensor. The new sensor is using the optical sensor which is triggered by a simple mechanical lever. This sensor doesn’t care about the optical properties of the filament (it can be completely invisible) and cannot die because of mechanical wear.
The new EINSY RAMBo motherboard with Trinamic drivers not only makes the MK3S+ silent but it also can detect skipped steps and layer shifting. This is a big step forward in the reliability of the printer and the user comfort. You can say goodbye to ugly prints!
Have you ever tripped over the extension cord and lost a 20-hours print? MK3S+ will save you! The printer can fully recover from the loss of power. It detects power interruption and shuts down the heatbed and extruder heating. After restoring the power, you can continue with printing.

If you don't need a full MK3S upgrade, you can use our upgrade to MK2.5S. It offers most of the important new features of MK3S and is significantly cheaper.
Printed parts are NOT included! You will need your MK2/S fully functional to print the parts! (Filament is included in the upgrade package and G-codes are available at prusa3d.com)
Still Cheaper than a new MK3S
Brought the upgrade, instructions are amazing. When with full upgrade as it had some of the features i needed and wanted. Still have heaps left over from my Mk2S though.
Getting the latest without the pain.
Wow, what an easy upgrade. Basically an entire printer kit as every parts is new minus Steppers and LCD but with the economy you expect from Prusa. All parts were correct and matched instruction without issue. Printed parts with the included PETG. Shipping to USA was fast. Had kit in hand seven days after ordering. Would recommend anyone looking to upgrade to go with the complete MK3S upgrade kit.
Fantastic Upgrade
As expected a fantastic upgrade turning a great mk2 into a fabulous mk3. Nice easy upgrade easy to follow instructions and everything you need in the kit.
Has transformed my mk2 into a super quiet machine. Highly recommend the upgrade or a full mk3 kit.
