Smart compact open-source 3D printer by Josef Prusa
November 2020 Update: The improved version of the Original Prusa MINI (the MINI+) now shipping! Read everything about it here.
While a large print platform has its advantages, you can produce a higher number of parts when you utilize parallel printing!
With its small footprint, the MINI+ fits pretty much everywhere. Run the print job on 2+ 3D printers to maximize your production!
The MINI+ was designed to be a true 3D printing workhorse and it offers the same level of reliability and quality as the rest of the Original Prusa family.
Featuring a 7"×7"×7" (18×18×18 cm) build volume, the MINI+ is a fully-equipped 3D printer. With sensorless homing, automatic Mesh Bed Calibration, replaceable nozzles, network connectivity, USB and LAN printing and a full-color LCD screen, the MINI+ is a big printer in a small body.
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.
Automatic Mesh Bed Leveling with the brand new SuperPINDA sensor, self-diagnostics, ethernet... the Mini is packed with smart tech making the 3D printing process a breeze. Just insert a USB drive and confirm the selection, the printer will do the rest for you!
More power, more options. Our brand new custom-made 32-bit Buddy motherboard with Trinamic 2209 silent drivers brings more bang for your bucks. The printer also features three thermistors and a number of safety features for trouble-free printing.
The MINI+ is fully supported in our own open-source slicing software, PrusaSlicer. This feature-rich, frequently updated tool contains everything you need to export perfect print files. We provide fine-tuned profiles for all supported materials.
We are always working hard to help you start printing as soon as possible. Our printers come with detailed assembly instructions and a 3D printing handbook. We offer 24/7 tech support via live chat and e-mail in 7 languages. You can also use our community forum and knowledge base.
"I think the MINI is a great machine, especially for the price. You won't find a more complete package of solid hardware, usable firmware, good documentation and great software under 400 bucks.”
"This small and sturdy machine uses an excellent slicer, comes with a magnificent metal bed and, overall, gives you excellent print quality. It’s difficult to see how anyone could be disappointed with it.”
"Right out of the box, this thing is so impressive (...) You can get yourself pretty much what I consider to be a top-of-the-line performance printer for 350 USD.”
"When we weigh up the price, performance, reliability and overall product, it is highly recommended for most people to purchase because it does things so well.”
"The MINI has become my favorite 3D printer of 2020 (...) It's the out-of-the-box experience: once you assemble it, there's very little else to do to it except for just slice the model and print it.”
"Prusa have done all they can to pack the features of their best selling 3D printers into a smaller and cheaper package. The Mini may be small but it’s reliable, built to last and delivers excellent print quality just like it’s bigger siblings.”
