ORIGINAL PRUSA MINI+

SMART AND COMPACT 3D PRINTER FOR EVERYONE!

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. And we pushed the price under 349 USD / 379 EUR (VAT incl.)!

WITH THE ORIGINAL PRUSA MINI+ WE ARE INTRODUCING:

SuperPINDA

SuperPINDA is a temperature-independent probe that doesn’t suffer from temperature drift and makes the first layer consistent – for example if you are running one print after another but set the Live Adjust Z with a cold printer.

Y-Axis improvements

The U-bolts which were used to secure the Y-axis bearings are gone, too. Instead, there’s a new set of metal clips, which are easier to mount and provide slightly better support for the bearings.

New firmware features

We are improving the firmware regularly on all our printers. However, with MINI+ we have huge plans and we keep adding new features. We have already introduced Prusa Connect Local in 4.0.5 and even more exciting things are about to come!


WHAT WE ARE PROUD OF...

The most significant features of Original Prusa MINI+

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.

NETWORK CONNECTIVITY

The MINI+ comes standard with an ethernet RJ45 port and optional future ESP Wi-Fi module upgrade. Send files to the printer wirelessly, or download OTA firmware updates. Thanks to the 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.

COMPACT SIZE

With a footprint of 38×33 cm (15×13 in), the MINI+ is an incredibly compact, yet fully equipped 3D printer, allowing you to stack several machines onto a single shelf. No matter whether you’re limited by space, or you want to build a printing farm - the MINI+ has a perfect size.

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.

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.

GEARED EXTRUDER

To decrease the weight of the extruder, we moved the extruder motor on the Z-axis column. Using a 3:1 drive gear ratio, the printer pushes the 1.75 filament strand through a PTFE tube into the hotend and through the 0.4mm nozzle.

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).

Frustrating

I own multiple prusa printers and a dozen other printers from other companies. This is by far the most unreliable prusa I have ever owned. It’s only reliable at jamming and leveling issues. I now have just as many failed prints as completed ones. It’s defiantly a let down for sure. Soon as I get one issue fixed another one comes back. Filament type and brand has yet to make much difference. Wish I could offer a resolution but there doesn’t seem to be a reliable fix... I hope they get this printer reliability up to mk2 and mk3.

    A great printer, but definitely has significant bugs

    I am one of the first people to get the Prusa Mini and have had it for a few weeks now (it was delivered Mid-December). Assembly was mostly painless, and calibration was easy. I ran some first prints using the included sample filament, and the quality was superb. I was thrilled: Great quality, easy assembly, everything was great that night.

    The next day, I tried some low-quality cheap generic PLA I had on hand. It printed the first several layers, and then jammed. I tried the included sample stuff on a different, larger model and no problems. I decided, oh well, probably was my cheap generic PLA. I then ordered some Hatchbox PLA on Amazon, which is generally well-received online as a good filament.

    Lo and behold, I tried printing with Hatchbox and still had the exact same problems. Constant jamming. Included Prusament? No problems whatsoever. I gave in and ordered some Prusament, and wondered what to do with my Hatchbox.

    It turned out I wasn't alone, and that Prusa's manufacturing line had botched the extruder assembly. I followed some instructions posted by forum members and raised the extruder and MINDA probe, and tried to recalibrate. Because the forum members had not made a video (and Prusa hadn't done much to respond), I set my MINDA probe too high and dented my new steel sheet on this printer. I then set my MINDA probe much lower, recalibrated, and I could finally print my Hatchbox and Generic Filament.

    For a few days, at least. Then, all of a sudden, my calibration was off and I was having problems. Turns out the MINDA probe's wiring had an internal fracture because the factory made the zip ties too tight, and I wasn't alone with this problem. Free replacement, but it was out for a week... during Christmas (which was disappointing).

    So, a few days ago, got new MINDA probe, had to carefully cut the excessively tight zip ties, and had to undo all of the careful wiring and wire wrapping that the factory had done. I then ordered new zip ties, which will arrive today. I also then printed the "MINDA saver" and "Prusa Mini Hotend Stress Reliever" parts from Thingiverse and installed those, where (I hope) that this will prevent the MINDA probe wiring from snapping again.

    And while I'm at it, another factory problem: I recently bought a nice and fairly expensive wood tabletop. Someone at the factory screwed the mainboard in too tight, and because the control box is flush to the surface (while the rest of the printer is on rubber feet), it scratched up my new wooden tabletop quite badly, as it only takes a bump to scratch. I guess I'll have to sand it down, but still!

    And while I'm at this all: The Y-axis bearing has begun to squeak. It's not the bearing itself, but rather it's too close to the PETG frame and is rubbing against it. I guess I'll have to file that down to stop the squeaking.

    So, I guess my thoughts are: I've had lots of paper cut frustrations with this first run. The printer itself works great (thus the 4 stars) and is otherwise reliable and of excellent build quality. Still, the MINDA probe breaking, denting my new steel sheet, and scratching my desk is frustrating, and Prusa not making videos about how to fix these problems (so we have to rely on the community) is irritating. I would not have dented my steel sheet if Prusa had quickly made a video on the problem or been more involved with the fix.

    Overall: It's a great printer, but manufacturing needs work. I guess it's a first run, but I was hoping for a little better.
