Creality Releases SPARKX i7 CAD Files Under a License That Requires Permission for Commercial Copies
Creality’s first SPARKX Open Initiative release puts i7 CAD models and board pinouts on GitHub under OCL v1.1. Firmware and software source are not included.
On October 20, Creality published SPARKX i7 CAD models and circuit-board pinout images on GitHub, so owners can design mounts, accessories and repair parts against Creality’s own reference models. They use the Open Community License, which Prusa Research introduced in December 2025; Creality uses version 1.1, published in June 2026. Commercial copies of the printer, its parts or derivatives need a separate license. Firmware and software source are not included. Creality says more software- and firmware-related resources are planned for release in stages, with no dates.
Reference models and board maps, under a license with a commercial line
The full printer assembly, a simplified front-shell assembly and five smaller parts, plus MainBoard, ExtruderBoard and Y-axis board images.
Personal use, changes and shared remixes are allowed. Commercial copies need Creality’s separate license.
Creality says more software- and firmware-related resources are planned in stages, with no dates.

The SPARKX i7’s CAD models and board pinouts are public; its firmware and software source are not in this release
Creality’s October 20 post announcing its SPARKX Open Initiative released the first batch of SPARKX i7 structural CAD reference files and PCBA interface specifications in a new CrealityOfficial/SPARKX_I7 repository on GitHub. The repository holds seven STEP models, from the full printer assembly and a simplified front-shell assembly to the toolhead front cover, nozzle cleaner, silicone sleeve, cutter assembly and hotend nozzle, plus seven images of the MainBoard and ExtruderBoard interfaces and pinouts and the Y-axis vibration compensator interfaces. Its changelog, dated October 20, says six STEP models; the file list now has seven because a hotend nozzle model was added later.
Creality says owners can study, use, modify and share the files within the license, and gives the example of checking the printer’s dimensions and mounting points before designing a custom tool organizer. That makes it possible to design mounts, accessories and repair parts against Creality’s own reference models instead of measuring by hand, and to check board connectors before planning an add-on. The Crafty Catsman does not own a SPARKX i7 and has not opened the files, so this report cannot confirm how cleanly they import into common CAD tools. Firmware and software source are not included. Creality says more software- and firmware-related resources are planned for release in stages, with no dates, and that the i7 and i8 already provide access to Fluidd, Moonraker and SSH, which the site has not tested. Creality’s post notes that the source of Creality Print, the slicer the i7 product page lists, is already on GitHub; this release adds no printer firmware source.
Design freely for your own printer; the license draws the line at commercial copies
The models and board images use the Open Community License, version 1.1, with no add-on conditions; the repository’s README files, changelog and file list are under a separate CC BY-NC 4.0 license. Under OCL v1.1, non-commercial users may use, copy and modify the files, and anything they distribute that is derived from them must stay under OCL; creations not derived from the product are outside the license. Business users may use and modify the files solely for internal business use, including internal production. Copying or replicating the printer, its components or derivatives for any commercial purpose needs a separate business or repair license from Creality, with internal right-to-repair as the exception.
Open to tinker, not open to commercial copies: Prusa Research introduced the Open Community License in December 2025 with its CORE One CAD files, published version 1.1 in June 2026 and says it designed the license as a template any business or creator can use; Creality’s license file points to the text in the license project’s own repository. Creality’s repository describes itself as “Open source for sparkx i7,” but what it releases is reference geometry and connector maps under a license that requires Creality’s permission for commercial copies, with firmware and software source not included. For the SPARKX i8, Creality plans to release selected structural, hardware, software and firmware resources in stages, completing the rollout within six months of the i8’s official retail launch, for which it gives no date; its post links the i8 to an Indiegogo crowdfunding campaign.
- When will Creality release the i7’s software- and firmware-related resources, and will they include source code?
- How will Creality grant the separate business or repair license that commercial copying requires, and on what terms?
- Does Creality read the accessory line the way Prusa Research, the license’s author, does?
- Which i8 resources count as selected, and when is the i8’s official retail launch?
Hold off if:You want the i7’s firmware or software source, or plan to sell parts copied or derived from the files without first getting Creality’s separate license.
Use the files if:You own an i7 and want to design mounts, accessories or repair parts for your own printer, and you will keep any shared remix under OCL.

Use the files to design for your own printer, and check the license before you sell.
Check fit against Creality’s reference models and board pinouts before you print. Shared remixes must stay under OCL.
Selling copied or derived parts needs Creality’s separate license. Ask Creality before selling an accessory designed around the files.
Creality publishes the first SPARKX Open Initiative files
Creality’s October 20 post and its GitHub repository release SPARKX i7 CAD models and board interface images under OCL v1.1. The repository shows the files committed on October 19 UTC; the post and changelog date the release October 20.

Frequently Asked Questions
Can I sell parts or accessories made from the SPARKX i7 CAD files?▼
Not parts copied or derived from the files without Creality’s separate business or repair license. OCL v1.1 lets non-commercial users use, modify and share derivatives under the same license, and lets businesses use the files internally, including internal production. Accessories are a different case: Prusa Research, which wrote the license, says designing an accessory that only uses the files to read dimensions and match the fit is not a derivative, and that a design becomes one when the licensed geometry ends up inside it; the license’s worked examples also say creations not derived from licensed designs fall outside it. Creality has not published its own reading, so ask Creality before selling anything close to that line.
Did Creality release the SPARKX i7 firmware source?▼
No. The October 20 release covers structural CAD models and circuit-board interface images. Firmware and software source are not included. Creality says more software- and firmware-related resources are planned for release in stages, with no dates, and that the i7 already provides access to Fluidd, Moonraker and SSH.
