Not yet in SimplyPrint through Klipper (Moonraker): download the file before the print starts. ## What slicer to use for the LulzBot Mini 3 None of the slicers in SimplyPrint's cloud has a ready-made profile for the LulzBot Mini 3, but it takes standard G-code: start from a similar printer's profile and set the bed size, height and nozzle to match. - [PrusaSlicer](https://simplyprint.io/features/slicer/prusaslicer): No profile for the LulzBot Mini 3 · Runs in the SimplyPrint cloud - [OrcaSlicer](https://simplyprint.io/features/slicer/orcaslicer): No profile for the LulzBot Mini 3 · Runs in the SimplyPrint cloud - [BambuStudio](https://simplyprint.io/features/slicer/bambustudio): No profile for the LulzBot Mini 3 · Runs in the SimplyPrint cloud - [ElegooSlicer](https://simplyprint.io/features/slicer/elegooslicer): No profile for the LulzBot Mini 3 · Runs in the SimplyPrint cloud - [CrealityPrint](https://simplyprint.io/features/slicer/crealityprint): No profile for the LulzBot Mini 3 · Runs in the SimplyPrint cloud - [Cura](https://simplyprint.io/features/slicer/cura): No profile for the LulzBot Mini 3 · Runs in the SimplyPrint cloud - [Kiri:Moto](https://simplyprint.io/features/slicer/kirimoto): No profile for the LulzBot Mini 3 · Runs in the SimplyPrint cloud We only list slicers you can use in the SimplyPrint cloud, so there may be others for the LulzBot Mini 3. ## The app for the LulzBot Mini 3 SimplyPrint works as the LulzBot Mini 3's app: on your phone and in any browser, with a slicer in the cloud. - An app for iPhone and Android, the same in any browser, and a slicer in the cloud. - More than monitoring: a print queue, AI failure detection, AutoPrint and accounts for a team. - Printers from many brands in one place, side by side. - Hosted in Frankfurt, Germany, under the GDPR.

That's what plate swappers like these use: they take the finished plate off and slide a fresh one on. Without a kit, a G-code routine can push cooled prints off with the toolhead. For example: [JobOx](https://simplyprint.io/features/autoprint/jobox), [swapmod](https://simplyprint.io/features/autoprint/swapmod). ### Ways to automate it - [Push prints off with the toolhead](https://simplyprint.io/features/autoprint/push-off): On a bed slinger, a G-code routine can sweep the cooled print off the bed before the next job starts. - [Your own ejection G-code](https://simplyprint.io/features/autoprint/custom): Write the routine that clears your plate, and AutoPrint runs it after every print. - [A robot arm, or anything with an API](https://simplyprint.io/features/autoprint/api): Tell SimplyPrint the plate is clear through the API or a webhook, from a robot arm or your own system. - [Clear it by hand, keep the queue](https://simplyprint.io/features/autoprint/manual-mode): AutoPrint waits for you to mark the plate clear, then starts the next job. [How AutoPrint works](https://simplyprint.io/features/autoprint). AutoPrint comes with the Pro plan and up. ## LulzBot Mini 3 specifications: bed size, print height and more ### Size - Build volume: 180 x 180 x 180 mm - Bed type: Square - Bed size: 180 x 180 mm - Max print height: 180 mm ### Printing - Enclosure: Open frame - Motion system: Bed slinger - Max print speed: 500 mm/s - Max extruder temperature: 290 °C - Has heated bed: Yes - Max bed temperature: 100 °C - Number of nozzles: 1 - Toolheads: 1 - Direct drive: Yes - Probing tool / Auto Bed Leveling: Yes - Filament width: 1.75 mm ### Multi-material - Toolchanger or hotend changer: No - IDEX (independent dual extruders): No ### Connecting - Connectivity: Wi-Fi, USB - Built-in camera: No - Prints from: USB stick - Supports serial printing: No - Shipped firmware: Klipper ### Files and slicing - Supported file formats: G-code (.gcode, .gco, .g) ### The printer - Printer manufacturer / brand: LulzBot - Printer model name: Mini 3 - Made by a company from: USA - Launched: July 18, 2024 - Still made: Yes [Read more by the manufacturer](https://buy.lulzbot.com/products/lulzbot-3d-printer-mini-v3-boxed-for-retail-na) ## What filament can the LulzBot Mini 3 print?

The brand, which dates itself to 2011, was built up by Aleph Objects of Loveland, Colorado; after near-closure in 2019 it was bought by FAME 3D, which runs it from Fargo, North Dakota. LulzBot publishes its printer CAD, firmware and Cura LulzBot Edition slicer, and sells the TAZ and Mini printers to schools, labs and businesses that want a machine they can repair for years. - Founded: 2011 - Headquarters: Fargo, North Dakota, US - Ownership: FAME 3D, LLC (Fargo Additive Manufacturing Equipment 3D), privately held, since November 2019 - Website: https://lulzbot.com Openness: Open (5.0 of 5) Open-source hardware and firmware, published CAD, a deep parts catalogue and no cloud. The cost is a higher price than mass-market printers. - Firmware and custom firmware (5 of 5): LulzBot publishes its Klipper, Moonraker, Mainsail and Marlin forks under the GPL-3.0 on GitHub, updated through 2026, and the Mini 3 runs Klipper. The Free Software Foundation lists the LulzBot Mini and TAZ 6 as Respects Your Freedom certified. - Local control and integrations (5 of 5): The Mini 3 runs Klipper with Mainsail in any browser and prints over Wi-Fi or from a USB drive. LulzBot maintains its own Moonraker and Mainsail forks on GitHub, Moonraker's API is documented, and LulzBot offers no printer cloud or account. - Third-party filament, slicers and parts (5 of 5): Tool heads for 1.75 and 2.85 mm filament, any filament brand, the open-source Cura LulzBot Edition (LGPL/AGPL on GitHub) and OrcaSlicer profiles for older models. Tool heads are LulzBot designs, but their sources are published too. - Repairs and spare parts (5 of 5): LulzBot's shop lists about 155 spare parts, including parts for the TAZ 6 and Mini 1, and the CAD for the TAZ 8 and Mini 3 (GPL-3.0) is published on GitLab. - Data and privacy (5 of 5): No account is needed to print. LulzBot's privacy notice covers only its website and says personal data is not sold or rented. - Community and documentation (4 of 5): An official forum with posts every week, public GitHub and GitLab repositories and published assembly and support documents; the community is active but small. ### Pros - Open-source hardware and firmware, with CAD files published. - Spare parts still sold for printers from 2016 and earlier. - Runs locally (Klipper and Mainsail on the Mini 3), with no cloud account. - Made in the USA, with its own open-source Cura LulzBot Edition slicer. ### Cons - Expensive: the TAZ 8 listed at $5,395 and the Mini 3 at $1,695 in October 2026. - The company nearly closed in 2019, laying off about 80% of staff before FAME 3D bought it. - Current models are not in OrcaSlicer's built-in list; the main slicer is LulzBot's own Cura edition. ### Track record - March 2025: LulzBot introduced the TAZ 8, a large printer with swappable Galaxy Series tool heads. - July 2024: LulzBot introduced the Mini 3, running Klipper with the Mainsail web interface and Wi-Fi; its CAD is published on GitLab under the GPL-3.0. - November 2019: Aleph Objects sold its assets, including the LulzBot brand, to Fargo Additive Manufacturing Equipment 3D (FAME 3D) of Fargo, North Dakota. - October 2019: Aleph Objects laid off about 80% of its workforce in a cash-flow crunch while looking for new owners; it said it would keep making and servicing LulzBot printers and honour all warranties.
