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).

Awesome little printer

It's my second 3D printer, but first FDM printer (I already had SL1 for few years).

After almost a month of continuous printing with only PETG (except first test print with PLA) I'm very satisfied. After some tweaks to print settings almost no stringing and blobs. No print errors. No failed prints. For me this printer works like wonder. Now I don't even wait when starting new print to watch first layers - yes, I know that it's irresponsible but I know that it will print with just no problems. I just clean plate with IPA after each print to be sure it's clean.

For me only complication during assembly was the length of the LCD mounting screw (in the end it fits but I was very very uncertain and worried if I won'ť break the mounting point). I recommend using shorter screw.

If I will find more room space, I won't hesitate to buy another MINI+ printer.

Seriously, Just buy the Dam Printer...

I have an etsy shop and I sell a lot of 3d printed things. For years I've gone through more printers than underwear. Each time deciding to go cheap (sub $300) I've gone through no joke about 10 printers as of now. I finally decided to buckle up and buy 3 prusa minis. I figured I wanted to know what the hell was the big deal about these crazy expensive printers.

Well, egg on my face as it was the best dam thing I ever bought. Dependable doesn't even come close to expressing how well these have been working. They are fast and work and work and just WORK.

If you're cheap and don't want to spend a bunch of money on a printer like the $1000 mk3, then buy the mini if the bed size will work, they are IDENTICAL in quality and speed.

I bought 3, I may buy more, however, the one sucky thing is they don't play well with farm software like octoprint, AstroPrint - HOWEVER, the only thing bad about these software options is that the filament sensor is never detected and will continue to print when your filament runs out (Only when using the server software mentioned, other than that they work fine, if not great with them)

Amazing!!!

So this was my first 3D printer and as usual I would read reviews, watch videos on experiences to no end to make sure what I was going to buy would be good.

Well after 2 evenings of building my printer is alive and boy does it print well. Teamed with some prusament the prints are fantastic. Now I should be honest, its not issue free, nothing of such complexity ever is, but I wouldn't want it to be, I've had 2 periods of downtime where I've learnt soooooo much about how the thing works, how to tune it to get near-perfect prints (and I mean perfect) and how to maintain it extremely well. Without that downtime I would just expect the thing to work and when it doesn't throw my arms up in the air and email someone and not learn anything.

Once I've fully experimented with everything Ill be getting several more for a print farm for a new tech start-up. Should be fun :)

    Update - Defective new Mini plus (assembled)

    I wanted to get back after Prusa had a chance to correct the situation. After speaking to a manager that person was able to address my situation. A new part was sent and that fixed my issue. Mini Plus is up and running and printing and I have been able to learn and have fun on it. I was down for 4 days and that was reasonable.

    Excellent

    After first calibration, it just printed, no issues so far.
    The Filament samples delivered with the Printer were pretty brittle

    Defective new Mini plus (assembled)

    Received and assembled mini plus yesterday (not the kit). Spent several hours trying to but it would not pass the XYZ calibration. Can print a decent initial layer but prints were awful. Spent 6 hours on the phone with customer service and could not get it to pass calibration test or wizard (XYZ). That is OK because I know not everything can be 100% perfect. Was given the choice to send unit back from the USA and wait up to 30 days for repair the defective unit sent to me, or send half of the machine back and they will send a replacement part. Requested that they send the new axis ASAP and I will send the defective XY axis back and they can charge me if they don’t receive in a prompt manner. Just wanted to start printing after waiting several weeks for initial delivery. Denied. So a bit disappointed in the customer service for this issue.

    Very good little printer

    Assembly was easy-ish with the almost-assembled version.
    Although, there are 2 mistakes in the printed manual:
    The screw for the display is mentioned to be a M3x12, but actually you should use the M3x20. (there is no other M3x12 screw in the package except for the spare btw). Even when the 20mm screw is super hard to get in all the way. (I used a washer...)
    And the hole in the electronics box for the Y-axis servo cable is not where the manual says and the actual opening is borderline small to get that connector through)
    Had to read the PDF manual to get over that.
    Other than that, it was easy.
    The display is very nice. It shows you a preview of the item and is color + easy navigation with the wheel.
    The printer is really low noise compared to others.
    Print quality is excellent. All I needed to do was getting the 1st layer right and from there it was really good results up to now.
    Mesh bed levelling is godsent. No more fiddling with paper and dumb bed screws.
    Live-Z- Adjust is also very helful to get the perfect 1st layer dialled in.
    I'm a complete 3D printing newb (read and watched a lot before buying tho), and so far, this printer made it really easy to get into it without having to upgrade stuff or reading millions of forum posts to overcome quality problems.
    Yes, it's more expensive than some china clones, but I would spend that extra money again. It's worth it.
    You want to spend time on printing, not on making the device viable in the first place ...

    Exceeds expectations

    The print quality is excellent.
    Assembly was easy, started printing immediately and was surprised by the print quality.

    For the prototypes I need to print the size is convenient.

    I had 2 small issues:
    1 - the usb stick that comes with the printer is trash, kept getting errors and it blocked during prints; changed the stick with one of my own, everything fine since then
    2 - after a while the Y axis started to get noisy, had to tighten some screws, specially the ones holding down the heatbed and lubed the rods, after everything is silent again, but this is expected when there are moving parts and vibrations

    First printer, very happy

    I'd give it 4.5/5 stars actually. I only have to deduct a tiny bit from a perfect rating because of some minor design flaws that have been raised before (see comments in the online assembly guide).

    Pros:

    - Excellent print quality. Minimal stringing and blobbing, much better than videos I've seen of unprocessed prints from cheaper printers. I hardly have to do any post-processing except when I print with supports. I've only had one failed print so far, which was my fault - I neglected to enable supports for a model with some overhang.

    - Easy to use, and everything is well documented.

    - Compact despite a more than adequate build volume for my needs (functional parts for small robots and animatronics).

    Cons:

    - Smooth build plate longevity seems questionable. After a few weeks of printing I already have several small patches where the coating seems to have peeled off. I have only cleaned it with paper towel and 99% isopropyl alcohol. Maybe refreshing with acetone will help, and maybe it doesn't matter since bed adhesion is still good.

    - The optional filament sensor puts a lot of pressure on the filament and prevents it from smoothly traveling through. I think Prusa should have just used a soft-touch roller lever actuator or gone fully optical.

    - The screw attaching the LCD housing was way too long, it could not be driven in far enough to hold the LCD housing in place. Had to replace with a much shorter wood screw.

    These are fairly minor cons. If starting over I'd buy the same printer again, no hesitation.

    Amazing printer but room for improvements

    Had an amazing time with this printer, the quality of the prints are unmatched for the price. Very simple to setup and the pre-configured slicer settings work remarkably well.

    The only issue that i ran into was nozzle clogging which was discovered by a clicking extruder. Looks like the factory ptfe tube either was too short or had shrunk during my prints. Purchased a bondtech upgrade (extruder & heatbreak), currently running some benchmarks (first two are perfect quality so far).

    Print size is perfect, 95% of my prints fits.

    The printer produced the best benchy I've ever seen on .2 mm layer heights.

    Great purchase, i have my 2nd already on order, figured that its more value to get two of these and a spool of filament rather than a single mk3s. Also, it's 32bit which i assume is the future for prusa printers, so in a sense its also a more futureproof printer.
