170+ hours of testing: mean dimensional difference of 0.05 mm across repeatability prints and successful multi-material parts, with minimal waste. Downsides are unreliable filament sensing with false clog alerts and no print failure detection; calls it an excellent choice for beginners and professionals.
“the Prusa XL impresses with its versatility, multi-material capabilities, and large build volume.”
Tests the partly assembled five-head XL: about an hour of setup, then fast, very accurate multi-filament prints without the mess of other multi-material machines. Notes no enclosure, camera or touchscreen at the time and tool-head fittings that may not feel robust; hefty price, judged worth it.
“The XL is unmatched in terms of accuracy and speed in its category.”
Tests the five-toolhead XL with its 360 mm bed. Likes waste-free multi-material printing, automatic load-cell leveling and offline use; finds mixing very different filaments tricky and the price high, with quality put ahead of speed. Editor's Choice.
“Prusa’s XL is a pricey multi-material tool changer that keeps the emphasis on quality over speed.”

Single- and multi-toolhead tests against Bambu's AMS. Calls it the most advanced multi-filament printer; saves money if you print pricey engineering and support filaments, but costs far more than AMS machines and has a steeper learning curve. Prusa supplied the unit, VoxelPLA sponsored (disclosed).

Argues that for a 360 mm, five-tool machine at about 4,000 dollars nothing else in the pro segment competes; calibration and filament requirements took a while to figure out. Would not buy five heads himself and wishes for a cheaper XL-lite. Sponsored by Flexispot, unrelated to the printer (disclosed).

Review after months with a five-head XL he pre-ordered and paid for himself, focused on multicolor printing. Concludes it is in a class by itself and that buyers who want it will be happy; notes early units shipped with 0.6 mm nozzles and later ones with 0.4 mm.
Prusa Research is a Prague company founded in 2012 by Josef Průša, who came from the open-source RepRap project. It designs and builds the Original Prusa and Prusa CORE printers, makes Prusament filament, develops the PrusaSlicer slicer and runs the Printables model site. Printers are built in Prague and at its US site in Delaware, sold assembled or as kits, and used by hobbyists, schools, businesses and print farms.

Prusa is the most open of the large brands: GPL firmware, an open slicer, full local control without an account and spare parts for everything. Hardware design files now come under Prusa's own Open Community License, which allows personal and in-house business use but not selling machines.
固件和自定义固件 ●●●●●
Firmware for current printers is published on GitHub under GPL-3.0 and updated with every release. Official firmware is signed, but Prusa documents how to flash custom firmware by breaking a seal on the board and says this does not void the warranty. Prusa says firmware and printable parts are shared right away and electronics schematics later.

本地控制与集成 ●●●●●
PrusaLink, built into the CORE One, MK4S, MK3.9, MK3.5 and XL, handles monitoring, file uploads and print control on the local network without internet or an account, and printing from USB works offline. Prusa publishes PrusaLink's HTTP API as an OpenAPI specification on GitHub, and its help centre covers OctoPrint setup. Prusa Connect is an optional cloud service for remote access.
[4][15]
第三方耗材、切片软件和零件 ●●●●●
Printers are open to any filament; PrusaSlicer is GPL-licensed and other slicers work. Instead of a locked RFID system, Prusa created OpenPrintTag, an NFC spool-tag standard that is free for any brand to use and works offline.
[5][6]
维修和备件 ●●●●●
The e-shop sells spare parts for each printer, printable parts are published, and the full CORE One CAD files are released. Prusa's open-source page says its goal is printers that stay moddable and easy to repair for decades, and its licence explicitly allows making spare parts for your own machines.
[7][3][5]
数据与隐私 ●●●●●
No account is needed for local use through PrusaLink or USB. Prusa Connect needs a Prusa account and stores G-codes and telemetry in the cloud. Prusa Research is an EU company and publishes its privacy policy and a Trust Center.
[4][8]
社区和文档 ●●●●●
Large community around Printables and the forum, a detailed knowledge base, and firmware and slicer developed in public on GitHub with open issue trackers.

优点
GPL firmware with a documented, warranty-safe way to flash custom firmware.
Full control on the local network through PrusaLink, with no account needed.
Spare parts for every printer, published printable parts and released CAD files.
Kits available for people who want to build and understand their printer.
Made in Prague, with a second factory in Delaware for US buyers.
OpenPrintTag is an open spool-tag standard any brand can use.
缺点
Hardware files use Prusa's own OCL licence, which bars selling machines built from them; it is not an OSI open-source licence.
Electronics schematics are published later than firmware and printable parts.
Remote access and cloud storage need Prusa Connect and an account.
实绩
七月 2026: Printed Solid, the Delaware company Prusa Research bought in 2022, was renamed Prusa USA. Its Wilmington site builds the MK4S and CORE One+, makes filament and is Prusa's US service centre.
[9]
十二月 2025: Prusa released the full CAD files of the CORE One under its new Open Community License (OCL). OCL allows modifying, sharing mods and in-house commercial use, and grants patent and repair rights, but bars selling machines built from the files without an agreement, so it is not a standard open-source licence. Prusa said it is also filing patents on its designs.
[5]
十月 2025: Prusa launched OpenPrintTag, a published NFC standard for smart filament spools that any brand can use without licence fees, starting with redesigned Prusament spools.
[6]
十一月 2024: Prusa announced the CORE One, its first fully enclosed CoreXY printer with active chamber temperature control.
[10]
三月 2023: Josef Průša wrote that open source in 3D printing was under strain from cloners and licence violations. With the MK4, Prusa released firmware sources and models of the plastic parts but held back the electronics plans, planning to publish them later under a new licence.
