Creality Print 7.3.0

Creality Print v7.3.0 Release Notes

Creality Print 7.3.0 focuses on enhancing full-color and multi-color printing, further refining the complete workflow from color reproduction and color separation to mixed-color and gradient printing. We have also optimized purge waste utilization in multi-color printing, allowing a portion of purge material to be reused as internal infill where the model structure and available infill space allow, helping reduce material waste.

This release also introduces multi-nozzle, multi-diameter printing support for K3, Adaptive TPMS Infill, ZAA anti-aliasing, improved auto-orientation performance, faster slicing, and AI enhancements, further improving print quality, efficiency, and the overall user experience.

Full-Color & Multi-Color Printing Enhancements

Accurate Color Reproduction

Automatically matches target colors in the model to available filaments and generates optimized color-mixing combinations, reducing the need for repeated manual color-ratio adjustments and helping achieve printed colors closer to the original design. image 4 image 8

Two color-separation modes are available based on the selected filaments: use the existing filaments in the current filament list, or use a standard CMYW/RYBW filament set for color separation and matching.

Color prediction now uses a new algorithm based on measured filament spectral data. By incorporating actual spectral characteristics into color prediction, the algorithm can more accurately estimate printed colors and reduce color deviation.

In 36 sets of CMYK color-mixing tests, the predicted colors achieved an average ΔE00 of 2.85, compared with 8.63 using the traditional algorithm. Lower ΔE00 values indicate closer color matching between the predicted and printed colors. This algorithm has been validated with filaments such as Hyper PLA.

Note: ΔE00 is a metric used to quantify perceptual color difference. A lower value indicates a closer match between the predicted and printed colors.*CIEDE2000 Color Difference* ↗)

One-Click Color Separation for OBJ Models

Import OBJ models containing color information and automatically convert the embedded colors into editable painting data. Creality Print then matches the model colors with available filaments, significantly reducing the manual work required for coloring and filament assignment.

Flexible Gradient Color Control

Added gradient color support, allowing model colors to transition progressively based on print height or a specified region, creating richer color effects than single-color printing.

Users can freely add color anchors within a selected height range and define the gradient transition. Creality Print automatically generates the corresponding color changes based on the number of printing layers, making it suitable for models such as skies, flames, decorative objects, and artistic prints.

Multi-Color Printing: Purge Waste Reduction

Optimized Purge to Object Skeleton

This release further optimizes Purge to Object Skeleton, with the goal of reducing purge waste and improving filament utilization.

During slicing, Creality Print identifies hidden internal infill areas that can safely receive purge material and prioritizes these areas for reusing purge material as part of the internal structure. This allows more filament to contribute to the printed model while reducing material used solely for the wipe tower.
