The print queue & smart-routing engine

One print queue for the whole Prusa fleet

Drop in everything you need to make and set how many of each - SimplyPrint feeds every job to a Prusa that can actually run it, matching material, nozzle and sheet against each machine's live state. One click starts a whole batch across the rack. No SD cards, no walking USB sticks to the printer, no spreadsheet of who-printed-what.

Deep Prusa integration

Deeply integrated with Prusa

SimplyPrint runs Prusa printers in the cloud and speaks the ecosystem natively: a direct connection that needs no extra hardware (beta), full control of every Prusa feature, and the real PrusaSlicer engine for slicing - one panel for all of it.

An Original Prusa MK4 connected directly to SimplyPrint and controlled live from the panel

SimplyPrint's own open-source firmware connects newer Prusa printers directly - no Raspberry Pi, no bridge box, no host computer. Flash it once and the printer talks to SimplyPrint over its own Wi-Fi or Ethernet. Supported on the CORE One, MK4, MK4S, MK3.9, MK3.5, XL and Mini+ (it's currently in beta, with no webcam yet). Older MK3-class printers connect through OctoPrint instead - the most mature path, and it adds a webcam. How Prusa printers connect

Full control of an Original Prusa MK4 in SimplyPrint - temperatures, jog controls, print queue and print history

Once connected, a Prusa behaves like any other printer in SimplyPrint - live temperatures and status, jog and homing, start, pause and resume, and one-off G-code for calibration or maintenance routines, all from the browser or the app. It uses the Prusa's own features; you just drive them from anywhere. See printer management

The real PrusaSlicer running as a first-class cloud slicer engine inside SimplyPrint

The real, unmodified PrusaSlicer runs as a first-class cloud engine: slice an STL to G-code right in the browser (or headless, automatically) and drop it straight into a Prusa in the queue. PrusaSlicer in the cloud

Also in the box: Prusa MMU2/2S and MMU3 multi-material support, filament usage tracking and inventory, usage-based maintenance, and the full REST API for your fleet. The direct firmware is open source on GitHub.

Up and running in an afternoon

SimplyPrint installs across a whole farm fast - no new hardware to buy. Add your printers and the whole fleet lands in one panel the same day.

An all-Prusa shop? You're covered - and never boxed in

Prusa is one of the biggest brands among SimplyPrint print farms - 1,900+ connected printers - and SimplyPrint runs it natively. But it isn't Prusa-only: the next printers you add don't have to be Prusa, and if you already run a few that aren't, bring them into the same panel too - 130+ brands run side by side, same queue, same screen. See the full print-farm platform.

Newer Prusa printers connect with the SimplyPrint custom firmware (beta) - no extra hardware at all. Older MK3-class printers connect through OctoPrint on a Raspberry Pi (the most mature path, and it adds a webcam). Either way, all you need is an internet connection.

SimplyPrint has meant that our print farm runs optimally every day and that the jobs we receive are always produced on time and in the right amount. With up to 720 daily print hours, it would be a big challenge to keep track of the tasks without it.

Frequently asked questions

SimplyPrint has its own open-source firmware for newer Prusa printers - the CORE One, MK4, MK4S, MK3.9, MK3.5, XL and Mini+. Flash it once and the printer connects directly over its own Wi-Fi or Ethernet: no Raspberry Pi, no bridge box, no host computer. It's currently in beta (no webcam yet, and downloads are slower than the classic path). Older MK3-class printers (MK3, MK3S, MK3S+) connect through OctoPrint on a Raspberry Pi instead - the most mature setup, and it adds webcam support. See the Prusa setup guide.
Yes - the cross-brand one. Prusa Connect is Prusa's own free cloud, and it's genuinely good for an all-Prusa shop: first-party, EU-hosted, now with a cloud slicer, apps and teams. But it manages Prusa hardware only, and it has no AI failure detection, no continuous (lights-out) printing, no filament inventory and no maintenance system. SimplyPrint runs Prusa and every other major brand in one farm and adds all of that. The two can run side by side. See the full Prusa Connect comparison.
All of them. Every current Original Prusa model is in the catalog - from the Mini+ to the MK4S, XL and CORE One, plus the classic i3 MK3 line. Newer models connect with the direct firmware; older MK3-class printers connect through OctoPrint. See the full, always-current list on this page, or check the compatibility list.
Yes. The real, unmodified PrusaSlicer runs as a first-class cloud engine, so you can slice an STL to G-code right in the browser - or headless, automatically - and send it straight to a Prusa in the queue. More on PrusaSlicer in the cloud.
Yes. SimplyPrint isn't Prusa-only: 130+ brands and 600+ printer models run side by side in the same panel - Bambu Lab, Creality, Anycubic and more - with the same queue, permissions and statistics. Many Prusa farms mix in other brands as they grow. Check the compatibility list.
Yes, on any Prusa with a camera. Prusa printers don't ship with failure detection, so this is a genuine add: the AI watches the camera feed, catches a failing print early, and confirms the bed is clear before the next job starts. Connect a Prusa through OctoPrint for built-in webcam support. See AI failure detection.
Your printers don't become useless. A print started through SimplyPrint is transferred to the printer, so it keeps going, and we pick the progress back up when you reconnect. SimplyPrint also runs at 99.9%+ uptime (tracked live on our status page).
