The promotion also discounts selected Prusa Academy courses, filament, resins, and merch, while CORE One machines get free extras instead of straight price cuts.
Prusa’s back-to-school sale is live through September 30, with the biggest hardware discount landing on the Original Prusa MK4S. The assembled version is 20% off at $799, down from $999, while the kit gets a 10% cut to $639 from $709.
Both versions also come with Prusa Academy’s “Design Principles for 3D Printed Parts” course for free.
The CORE One+ (Gen 2) and larger CORE One L+ stay at their regular prices, but Prusa is padding out the packages with free filament and the same Academy course. Here’s the printer deal breakdown:
There are also discounts on a handful of Prusa Academy courses, at almost half price:

There are a few smaller discounts if you don’t need another printer. Prusament PLA and PETG, plus Prusa’s resins, are 15% off; Prusa merch is 10% off. The Starter Paint Set and Miniature Painting course bundle also gets special back-to-school pricing.
One thing absent is INDX. Prusa explicitly excludes INDX-equipped CORE One+ and CORE One L+ variants from these printer offers. That’s worth keeping in mind given that Prusa has only just expanded INDX into a sprawling 14-SKU lineup of complete printers and upgrade kits.
All of the offers are live now on Prusa’s webstore and run through September 30.
