¶ New Features
¶ Added Scarf Joint Seam Feature
Scarf Joint Seam is used to conceal seams on models with fewer edges, making the seams less abrupt by turning them into short ramps, thereby improving print quality.

You can enable this setting under Quality - Seam - Scarf joint seam.
¶ Added Bridge Counterbore Holes Feature
This feature allows bridging for sink holes, enabling printing without supports to enhance printing efficiency, save support material, and simplify post-processing steps.
You can enable this setting under Quality - Bridge - Bridge counterbore holes.
¶ Added AI Infill Feature
This feature densifies infill near walls while keeping infill sparse in the center of the model, reducing material usage and improving printing speed.
You can enable this setting under Strength - Infill - AI infill.
¶ Added Model Integrity Check and Repair Feature (Windows)
To prevent printing failures caused by damaged models, we have added a model integrity check and repair feature (repair function supported only on the Windows version).
- When you pick a damaged model, a prompt will appear in the bottom-left corner.
- You can click the "Repair Model" button to fix the model instantly, or right-click and select "Repair Model."
- Repair completed.
¶ Added Assemble Feature
The assemble feature allows you to group model objects, making it easier to batch adjust filament usage and process parameters within the group.
For example, you can modify filament usage for objects within the group in bulk.
¶ Added Part Feature
Parts are subsets of objects, and final slicing generates path data only for these parts. Other types of parts (such as negative part, modifier, etc.) are used solely for modifying these parts and do not generate path data.
¶ Added Negative Part Feature
When you need to create a recessed effect, where one shape subtracts from another shape within a model, you can achieve this with the negative part feature. Negative part subtraction occurs only during slicing and does not alter the geometry of the objects, thus it cannot export STL files containing subtraction results.
¶ Added Modifier Feature
The modifier feature allows for localized adjustments of part characteristics when different process parameters or filament settings need to be applied to specific areas of solid parts.
For example, setting a sparse infill density of 50% in areas where modified objects overlap with the modifier.
¶ Added Support Enforcer and Blocker Features
You can easily select parts where supports need to be added and parts where supports should be blocked using this method.
- Support Enforcer
- Support Blocker
¶ Added 3MF Project File Upload to Creality Cloud Feature
Upload 3MF project files to Creality Cloud for convenient sharing and storing of your work.
¶ Added Language Support (Japanese, Korean, French)
You can select additional languages in the preferences settings.
¶ Added Enhanced Error Message Prompts
Improved pre-print checks to identify anomalies and enhance print success rate:
- Model collision detection
- Model overhang detection
- G-code path conflict detection
- G-code exceeding heated bed boundary detection
- Model empty layer detection
¶ Improved Performance
¶ Added speed improvement after modifying parameters and re-slicing
After slicing the model in version 5.1, if you modify the relevant parameters and slice again, the speed improves compared to previous versions. For example, if you move the model and slice again, the speed increases by approximately 33% compared to the previous version.
