Original Prusa i3 MK3S kit

 PRI-MK3S-KIT-ORG-PEI

 New product

The Original Prusa I3 MK3S is the successor of the award-winning Original Prusa i3 MK2 3D printer. With the rebuilt extruder, a plethora of sensors and the new magnetic MK52 heatbed with replaceable PEI spring steel print sheet we believe that we've developed our best 3D printer yet!  

This listing is a DIY KIT for self-assembly.

After more than a year of a continuous development of the Original Prusa i3 MK3 we are introducing MK3S - the enhanced and improved revision of the MK3.

WITH THE ORIGINAL PRUSA i3 MK3S WE ARE INTRODUCING:

NEW FILAMENT SENSOR

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.

BETTER SERVICE & PRINTS

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.

DOZENS OF TWEAKS

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 Original Prusa i3 MK3/S is the "Best 3D printer" according to All3DP.com and MAKE: Magazine, where MK3/S also received "Editor's Choice" as the highest-rated 3D printer in 2019 Digital Fabrication Guide. The MK3S features a rebuilt extruder, numerous sensors, and various smart features. Plus, a new magnetic MK52 heatbed with replaceable PEI spring steel print sheet. Dozens of various tweaks and upgrades improve the reliability and ease of use. MK3S‘s functionality can be further expended with the unique Multi-Material Upgrade 2S addon for printing with up to 5 materials simultaneously.

WHAT WE ARE PROUD OF...

The most significant features of Original Prusa i3 MK3S

REMOVABLE HEATBED

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, already available) and textured powder coated PEI (this will be available later). 

FRAME STABILITY

With the MK3S we are introducing the reworked Y axis from aluminum extrusion. It provides the same rigidity as some other printers while providing the sleek look of our milled Dural frame. The frame is also optimized to add 10 mm of Z height totaling at 210 mm.

SILENT & FASTER PRINTING

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 printing speed. Now you can achieve more than 200 mm/s!

POWER PANIC

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.

FILAMENT SENSOR

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.

PREVENTS SHIFTED LAYERS

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!

BONDTECH EXTRUDER

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 especiallyfor flexible filaments. Also, the print fan now cools part from two sides, increasing the overall performance.

P.I.N.D.A. 2 PROBE

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 NOZZLE

E3D V6 is market-leading all metal hotend well known for its high-temperature performance. The MK3S utilizes a custom heatbreak developed together with E3D. The reliability has proved in our Multi Material upgrade and continues to deliver great performance in surprisingly small form factor.

WHY DO YOU WANT ORIGINAL PRUSA I3 KIT?

Great support

We are an established company founded in 2012, and we work hard to help you start 3D printing as soon as possible. We are providing full 24/7 customer support with live chat and e-mail in several languages. There are also unofficial user groups on Facebook, where makers help each other. You will never be alone in the big world of 3D printing!

The kit comes along with a forum support where our ever growing community can always help, or you can even get in touch with Jo Prusa himself at the very same spot! Check out the forum and regularly updated Knowledge Base!

With 3D printing, buying a printer is just a beginning!


Fun to assemble

Assembling the kit is an excellent first step to the world of 3D printing. You will understand the principles of printer construction and get a huge advantage when you need to solve possible problems and replacements later.

But don't worry. Assembling is quite easy! You don't have to solder at all to build our kit. You don't even have to own a soldering iron. All our cables are cut to length and with professionally crimped connectors. And from the electronics standpoint, the hardest thing will be plugging the connectors to the motherboard.

All of this makes the kit very friendly to younger builders :-)


Best assembly instructions and free 3D Printing handbook

We didn't want to leave anything to chance, so our assembly instructions are pictured to the smallest detail.

See the assembly manual for yourself!

All fasteners and mechanical parts have 1:1 drawing so you can easily find them, and there is no chance of you picking a wrong one. You don't have to be MIT graduate to assemble our kit ;-)

Our fastest customer built the kit in 4 hours! Will you beat him?


Ready to print settings

We provide high 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 ;-)

We are developing our own slicing software. In Slic3r Prusa Edition you can set everything you want. PrusaControl on the other side is focusing on casual users, and it's very easy to use. But of course, we also have the settings for the third party slicers like Simplify3D, Cura, etc.


Upgradability

One of the most popular features of Original Prusa i3 concept is upgradability. If you buy our 3D printer, you can upgrade it later to the new version, so you don't need to buy the whole new model every two years as you get used to for example with your phone or laptop. :-)

Upgrades are a great way not only for saving money, but also to learn about the construction of the printer's hardware. We are constantly improving our technology. A few years ago there was the Original Prusa i3 3mm which was upgradable to the Original Prusa i3 Plus 1.75mm (MK1). MK1 printer can become MK2S thanks to the next big upgrade and then you can go even for the latest MK3S (or MK2.5S if you wish).


Ready for the Multi Material Upgrade 2S

Original Prusa i3 MK3S Multi Material 2S is the unique consumer option to print with up to 5 different materials simultaneously. MMU2S comes with a redesigned body and a new filament loading mechanism. Instead of the previous Bowden system. The motorized selector head has a F.I.N.D.A filament sensor and a built-in blade, which prevents filament jamming.

Multi-material could be your next step in the 3D printing world and MK3S is completely ready for the upgrade.

BTW: Do you know, that you can easily print soluble interface supports with Multi Material upgrade? We have a pretty smart solution for you - check out the video!
