United StatesOriginal Prusa MINI+ Semi-assembled 3D Printer - Enclosure Bundle
The Original Prusa MINI+ is a smart, compact and fast 3D printing workhorse, equipped with all the bells and whistles you've come to expect from an Original Prusa 3D printer. The MINI+ is bound to surprise you! :-) With a print volume of 18 cm (7") cubed, removable spring steel sheets, ethernet, and optional Wi-Fi, it is built on our custom-made 32-bit embedded platform featuring silent 2209 Trinamic drivers.
It’s packed with many of the features you can find in its larger siblings - super-fast printing thanks to Input Shaper and Pressure Advance, remote print management via Prusa Connect, OTA firmware updates, advanced safety features, and support for advanced materials - even PA-11 (280 °C nozzle and 100 °C heatbed). It’s open-source, easy to maintain, and open to mods, tweaking and tinkering.
BETTER THAN EVER WITH 5.1.0 FIRMWARE!
We like to improve and our printers a long time after their initial release with both hardware and software upgrades. There is no better proof than the 5.1.0 firmware for the MINI+ which brings a number of exciting new features.
First of all, we’ve added Input Shaper and Pressure Advance which run natively on the printer’s embedded platform. With these technologies in place, the printer can run much faster than ever before while retaining a high quality of prints.
The MINI+ has also been updated with the latest network code, enabling full integration with Prusa Connect, our secure system for remote print management. You can now easily manage your prints via a web browser, upload new print files or even flash firmware remotely. However, MINI+ can still be fully configured and operated in a completely offline environment.
Plus, there are dozens of improvements under the hood! Safety checks, UI customization, Grafana integration, and more!
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.
Fast Printing
With Input Shaper, Pressure Advance and Precise Stepping technologies in place, the MINI+ delivers high-quality prints - fast! With factory-tested print profiles in PrusaSlicer, you can always find the best one for your project.
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 three variants: smooth, textured, and satin.
SuperPinda Probe
SuperPINDA probe features a high-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 height map of the print area. This process ensures that the first layer will be spot on!
Network Connectivity
The MINI+ is equipped with an ethernet port and you can also install the optional ESP Wi-Fi module upgrade to integrate the MINI+ with our remote print management system, Prusa Connect. It allows you to easily manage your printer remotely, start print jobs or even flash new firmware via a web browser window.
Safety Features
Every part of the MINI+ is thoroughly tested in-house, not just one unit from a batch. 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 operation.
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 Embedded Platform
More power, more options. Our brand new custom-made 32-bit “Buddy” motherboard with Trinamic 2209 drivers brings more bang for your buck. It runs Input Shaper and Pressure Advance natively without the need for an additional motherboard, and it also ensures full integration with our highly capable remote print management system, Prusa Connect.
