QIDI Slicer

QIDI Slicer is free desktop software for preparing models and sending jobs to compatible QIDI 3D printers. It is best suited to owners of QIDI high-speed Klipper machines who want slicing, calibration, and printer control in one workflow. The trade-off is a defined hardware and firmware range, plus no resin-slicing workflow.

Overview

QIDI Slicer is built on PrusaSlicer, which itself derives from Slic3r, and is released under the GNU Affero General Public License version 3. It accepts STL, STEP, 3MF, OBJ, and AMF models, then exports G-code or .gcode.3mf files. Multi-material printing is supported, making it useful for filament setups with more than one material, but resin printing is not supported.

The central qualification is hardware compatibility. QIDI names the Q1 Pro, X-Max3, X-Plus3, and X-Smart3, and describes support for QIDI high-speed printers running Klipper firmware. Firmware must be version V4.0.0 or newer. Owners outside that group should not choose it as a general-purpose slicer without confirming their machine first.

Key features

Preparation tools cover moving, scaling, rotating, cropping, coloring, repairing, combining, and splitting models. Adjustable parameters and calibration functions provide meaningful control for complex parts and different printing scenarios, rather than forcing every user into fixed presets.

Recent releases add practical production options. Version 1.2.2 introduced fuzzy-skin painting, scarf seams, up to nine beds, and batch slicing and exporting across beds. Version 1.2.5 adds Q2 configuration and lets Q2 machines export and send .gcode.3mf slice files. Version 1.2.4 synchronizes materials with QIDI Box; adding a physical printer for that connection requires an API key.

Printers can connect directly on a LAN by IP or through the internet. After signing in, users can operate printers linked to their QIDI Link account and create remote print tasks. QIDI Link apps for iOS and Android can scan to connect, monitor progress away from the printer, adjust printing parameters, and feed or retract material. This is a strong reason for QIDI owners to stay within the ecosystem, though it also makes the experience more dependent on QIDI accounts and hardware.

Pricing

The QIDI Slicer plan costs free. It is a free download with no trial period, subscription renewal, seat charge, or stated usage quota. The plan includes the listed QIDI printer support, slicing and calibration tools, multi-material printing, and printer connections. There is no paid tier to unlock additional slicer capacity, so users do not have to trade features for a cheaper plan; the real limits are compatibility and the absence of resin slicing.

Platforms

QIDI Slicer runs on Windows, macOS, and Linux. Windows and macOS downloads are provided through QIDI Studio, while Linux users are directed to GitHub releases. The current listed release is 1.2.5.

Linux AppImages depend on WebKit and may require a matching webkit2gtk package. Newer Linux distributions can also experience Fluidd-page crashes. On macOS x86, sending G-code through Link with a filename six to nine characters long can crash the software. These platform-specific caveats matter when choosing it for a managed workstation or older Mac.

Who it's for

Choose QIDI Slicer if you own a supported QIDI high-speed printer, have firmware V4.0.0 or above, and want model editing, calibration, LAN or internet sending, and mobile monitoring in one product. It also suits users who need multi-material filament printing and value an AGPL-licensed project.

It is not the right fit for resin printing, unsupported printers, or workflows that require a platform without Linux WebKit dependencies or QIDI-account integration. Users on Q2 machines should use a current release to obtain the stated Q2 configuration and file-sending support.

Pros and cons

Pros

• Broad model preparation: repair, split, combine, color, crop, and transform tools handle more than basic slicing.
• Remote workflow: LAN, internet, QIDI Link, and mobile controls can cover slicing through print monitoring.
• Multi-material support: suitable for compatible filament setups rather than single-material-only jobs.
• Free and open-source licensed: there is no software fee, and the project uses AGPLv3.

Cons

• Hardware boundary: support centers on named QIDI printers and Klipper firmware V4.0.0 or later.
• No resin slicing: resin-printer owners need another application.
• Platform caveats: Linux WebKit dependencies, possible Fluidd crashes, and a macOS x86 Link crash condition can disrupt some setups.
• Account and ecosystem dependence: remote operation and QIDI Box features require QIDI Link sign-in or an API key where stated.

Alternatives

PrusaSlicer is the natural alternative when you want a free, open-source slicer with broader platform coverage, including Android, iOS, web, Linux, macOS, and Windows.

Choose Eiger instead for a free cloud platform aimed at Markforged devices, or its paid standalone Offline Eiger option.

GrabCAD Print is a better match for Stratasys printer support and offers a free Standard plan plus a paid Pro tier.

Pick Kiri:Moto for a free, ad-free web application with extension, API, and self-hosted availability.

KISSlicer fits users who need a free single-extruder workflow or a $40.00 Premium Upgrade for expanded extruder use.

Orca-Flashforge is an alternative centered on supported Flashforge printers.

UltiMaker Cura provides free, open-source desktop slicing with Linux, macOS, web, and Windows support.

Bambu Studio suits Bambu-focused workflows, with optional networking and SD-card printing without the networking plugin.

Verdict

QIDI Slicer is a strong choice for owners of supported QIDI Klipper printers who want capable filament slicing and integrated remote control at no cost. Choose it primarily for the QIDI hardware connection and QIDI Link workflow; look elsewhere if you use resin, an unsupported printer, or a platform affected by its Linux and macOS limitations.
