What slicer to use for the Prusa Prusawire Core ONE
Prusa printers use PrusaSlicer, Prusa's own slicer. There's no ready-made profile for the Prusa Prusawire Core ONE in our cloud yet.
We only list slicers you can use in the SimplyPrint cloud, so there may be others for the Prusa Prusawire Core ONE.
Cloud-Based Slicer for Prusa Prusawire Core ONE: Use PrusaSlicer Online
Use PrusaSlicer and other slicers - directly in your browser with SimplyPrint's online cloud slicer. No installation required. Slice your Prusa Prusawire Core ONE models from any device, anywhere in the world!
Automatic Profile Updates: Profiles are automatically checked and fetched from the slicer GitHub repositories every day, as well as from our own open-source community-driven slicer profile database. This ensures you always have access to the latest profiles.
Note: Other slicers, such as Simplify3D, ideaMaker, SuperSlicer and KISSlicer, aren't in our cloud, so we don't track their profiles. They may still work well with your Prusa Prusawire Core ONE: check the slicer's own documentation or forums for a profile. You can also contribute profiles to our open-source slicer profile database on GitHub.
The app for the Prusa Prusawire Core ONE
SimplyPrint works as the Prusa Prusawire Core ONE's app: on your phone and in any browser, with a slicer in the cloud.
There's no plate swapper or auto-ejection kit for the Prusa Prusawire Core ONE in SimplyPrint yet, but AutoPrint can still keep it printing: once the plate is clear, it starts the next job from your queue.
Ways to automate it
Your own ejection G-codeWrite the routine that clears your plate, and AutoPrint runs it after every print.

What filament can the Prusa Prusawire Core ONE print?
Filament compatibility for the Prusa Prusawire Core ONE: the materials it can handle, judged from its hotend, bed, chamber and enclosure.
Filament
Suitability
Notes
PLA
Great
The easiest filament to print. Works on almost any printer; a heated bed helps adhesion but is not required.
PETG
Great
Comfortably in range (PETG likes a ~230-250C hotend and a ~70-85C bed).
TPU & flexibles
Great
The direct-drive extruder feeds flexible filament well. Print slowly for clean results.
ABS & ASA
With care
The bed is hot enough, but ABS and ASA warp without an enclosure, which is strongly recommended for clean prints.
Nylon (PA)
With care
Possible with care - an enclosure and very dry filament are essential.
Polycarbonate (PC)
With care
On the edge - PC really wants an enclosed, hot chamber to avoid warping.
Carbon-fiber & glass-filled
With care
Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle.
Tip: this is a general guide from the printer's specs - always check your filament's recommended settings. With SimplyPrint you can save a profile for each spool and track exactly what filament you have in stock.

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.
Firmware and custom firmware ●●●●●
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]
Local control and integrations ●●●●●
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]
Third-party filament, slicers and parts ●●●●●
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]
Repairs and spare parts ●●●●●
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]
Data and privacy ●●●●●
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]
Community and documentation ●●●●●
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]
Pros
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.
Cons
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.
Track record
July 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]
December 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]
October 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]
November 2024: Prusa announced the CORE One, its first fully enclosed CoreXY printer with active chamber temperature control.
[10]
March 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.
