Original Prusa MINI+ Semi-assembled 3D Printer

Introducing our new compact 3D printer with all the bells and whistles you would expect from the creators of the award-winning Original Prusa i3 MK2 and MK3S! The MINI+ is a big printer in a compact body. We did our best to squeeze as many features into the lowest possible price as possible. The MINI+ is great for beginners, companies looking to build a printing farm and 3D printing enthusiasts worldwide.

Smooth PEI print sheet included

By purchasing the semi-assembled MINI+ you gain free access to our online course: 3D Printing and Modeling for Beginners.

Alternatively, you can try the full "Prusa Experience" with the printer kit, which you will assemble by yourself (it takes around 6 hours), and learn more about how the printer works.

Original Prusa MINI+ kit

Leadtime 1–2 weeks

Original Prusa MINI+ - smart and compact 3D printing workhorse with all the bells and whistles you’re accustomed to when you buy an Original Prusa 3D printer. MINI+ will surprise you. :-) It has a print volume of 18 cm (7”) cubed, removable spring steel sheets, ethernet and optional Wi-Fi and it’s based on our brand new custom-made 32-bit Buddy mainboard with silent 2209 Trinamic drivers.

Main Features

Build Volume

Featuring a 7"×7"×7" (18×18×18 cm) build volume, the MINI+ is a fully-equipped 3D printer. Featuring sensorless homing, automatic Mesh Bed Calibration, replaceable nozzles, network connectivity, USB printing and a full-color LCD screen, the MINI+ is a big printer in a small body.

Color LCD Screen

Configure your 3D printer with ease and see previews of sliced models before you start printing! Thanks to the 2.8’’, 240×320 LCD screen with 65.000 colors, every option is just a few clicks away.

Flexible Print Sheets

Removing a print has never been easier! With the magnetic heatbed and removable spring steel sheets, you can remove a printed object merely by bending the steel sheet. The surface is easy to maintain and comes in two variants: smooth and textured.

SuperPinda Probe

SuperPINDA probe features a hiqh-quality sensor for a fully-automatic Mesh Bed Leveling process. Before every print, the printer 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!

Network Connectivity

The MINI+ comes standard with an ethernet port and optional future ESP Wi-Fi module upgrade which will enable sending files to the printer wirelessly, or download OTA firmware updates. Thanks to future updates you will be able to manage a whole print farm easily.

Safety Features

Every part we use is thoroughly tested in-house. This is why our 3D printers are highly reliable and safe to use. The MINI+ is equipped with three thermistors and comes with a high-quality power supply (Delta or Mean Well - depending on region) for safe and reliable information.

One-click Printing

Once you insert a USB drive with a sliced object, a new menu with an object preview window appears. Confirm the selection with a single click of the control wheel and watch the printer do the rest for you.

32bit Controller STM32

More power, more options. Our brand new custom-made 32-bit “Buddy” motherboard with Trinamic 2209 drivers brings more bang for your bucks. It’s capable of nearly everything OctoPrint can do, including farm management software (future firmware update).

      Please don’t buy this printer.I’ve owned this for about a year. First 7, 8 months were great. Only a couple problems popped up, but the past few months this thing has been a NIGHTMARE. It’s always and I mean ALWAYS having problems. I turn it on, the screens black, I fix the screen, the filament won’t extrude, the i fix the extruder, the Bowden tube gets clogged. It is CONSTANT issues. It sucks because I actually started an Etsy shop with this thing and was making descent money and now I can’t buy a new printer because I had to close my Etsy shop. It’s to the point where I hate spending 2 hours repairing because I know it’s gonna break the next day.Also, no warranty. I contacted them, trying to get my money back for this piece of junk. They’re like oh, have you tried replacing this? have you tried cleaning that? It’s so frustrating. Definitely never buying a Prusa again. I’m glad that companies like Bambulab are trying to overtake companies like Prusa who never innovate or add to the field.Basically if you’re ok spending more time repairing than printing, this printer is great. If not, don’t waste your money. Get a bambulab or something that’s actually descent.

      Pros. Delivery was fast, took 3 weeks with the mostly preassembled feature. Cons: I found the handbook not very helpful. My 1st 3d Printer was an Ender 3 Pro and the Prussa was confusing. Bed level is WAY high to start. After a mistake or 2, one that night have bent my bed (maybe). Ah, okay, you really have to crank down Z on the first layer test to THEN it sets itself to start there every time if you ask it to. But wow, dropping it 1.125 or so to get to the squish level. Tried to benchies thus far. Bit looked like crap early. The supplied PLA snap off at the loading feeder so now I have filament trapped in the tube. Cant purge it cause nothing to push it. Cant unload it as there is nothing to grab on to. So I have to take it apart to get to filament trapped in the tube. This si why I junked my Ender 3. Too much trouble vs printing. Also , DHL delievered it roughly when they said they would but I ASKED for it to be signed for. They didnt even ring my door bell or knock. Just left the package and ran. So very dissatisfied day one considering the Prussa is $500 delivered and Ender 3 is about $200.

      The prints on the smooth sheet are awesome, but i can't get anything to stick on the Satin sheet. Also, right out of the box the cooling fans are really loud, they are rattling, it kinda sounds like they are missing a ball bearing. And it's not even a week old.
