The CORE One L+ is Prusa's large enclosed CoreXY: a 300 x 300 x 330 mm build volume, a 60 °C actively heated chamber and a 290 °C hotend, assembled and calibrated at the factory. It is for workshops, labs and serious makers who want a quiet, dependable large printer for PLA through ASA and nylon.
Runs Prusa's Buddy firmware on xBuddy electronics like the CORE One L, which SimplyPrint's Prusa firmware (beta) supports. Not confirmed on this printer yet.

Prusa CORE One L+用アプリ
Prusa CORE One L+のアプリとしてSimplyPrintを使用できます。スマートフォンやブラウザーから監視・操作し、クラウドでスライスして、他のプリンターと一緒に管理できます。無料で始められます。 Prusaの純正アプリはPrusa appとPrusa Connectです。
Reviewer who ran the original CORE One L for over 1,000 hours finds the L+ fixes its worst flaw, nozzle-wipe failures, with a silicone brush, and adds finer GT1.5 belts and factory calibration. Prints in PLA, ASA, PA6-CF and TPU came out well. Complaints: the 290 C hotend limit and the $1,999 price.
“The CORE One L+ is a fast, quiet, easy to set up printer that is a joy to use.”
Prusa CORE One L+を選択するケース
Choose the L+ when you want a large enclosed printer that just works: Tom's Hardware, which gave it 4.5/5, calls it fast, quiet and easy to set up, and says it fixes the nozzle-wipe failures of the original CORE One L. It costs $1,999 and tops out at 290 °C, so for very high-temperature materials you would need Prusa's optional HT hotend. If you want multi-material, Prusa points to the INDX toolchanger (the CORE One L+ INDX) rather than the MMU3, which fits only through a DIY re-mount from a CORE One+ kit. If you don't need the size, the CORE One+ costs much less.
メリット
A 60 °C actively heated chamber and a large 300 x 300 x 330 mm volume, with ASA and PA6-CF printing well in Tom's Hardware's tests.
Tom's Hardware found it fast, quiet and easy to set up, and rates it 4.5/5.
Factory-calibrated, and the L+ adds a silicone nozzle brush and finer GT1.5 belts over the original L (Tom's Hardware).
Can run fully offline, the Wi-Fi module can be removed, and a Critical Infrastructure edition has no Wi-Fi or camera (Prusa).
Expected to work with SimplyPrint through the SimplyPrint Client, OctoPrint or Prusa Direct (not yet confirmed).
デメリット
Costs $1,999 (Tom's Hardware).
The 290 °C hotend limit is a complaint in Tom's Hardware's review; Prusa sells an HT hotend upgrade for higher temperatures.
No native MMU3: Prusa offers a DIY re-mount of the CORE One+ MMU3 and recommends the INDX toolchanger instead.
Largely single-material out of the box, and SimplyPrint compatibility is expected rather than confirmed.
おすすめの対象
学校適しています
Enclosed, quiet and easy to run, and SimplyPrint can queue student prints for approval; the price is high for a classroom.
ホビーユーザー適しています
A premium large enclosed printer with excellent reviews, though $1,999 is steep for a hobbyist.
企業最適
Large enclosed prints in ASA, nylon and composites, offline operation and a security edition; Tom's Hardware rates it 4.5/5.
プリントファーム適しています
Reliable and consistent, but no plate-clearing kit is in our sources and its SimplyPrint connection is expected, not confirmed.

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.
ファームウェアとカスタムファームウェア ●●●●●
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.
[1][2][3]
ローカル制御と連携 ●●●●●
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]
サードパーティー製フィラメント、スライサー、部品 ●●●●●
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]
修理と交換部品 ●●●●●
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]
データとプライバシー ●●●●●
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]
コミュニティとドキュメント ●●●●●
Large community around Printables and the forum, a detailed knowledge base, and firmware and slicer developed in public on GitHub with open issue trackers.
[1][4]
メリット
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.
デメリット
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.
実績
7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]
12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]
10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]
11月 2024: Prusa announced the CORE One, its first fully enclosed CoreXY printer with active chamber temperature control.
[10]
3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.
