¶ New Features
- Introduced Full Spectrum (Beta) printing.
Recommended Model: Snapmaker U1
Software Version: To use Full Spectrum (Beta), make sure Snapmaker Orca is updated to V2.3.3 or later, and keep your printer firmware updated to the latest version.
Recommended Filaments: For optimal print results, we recommend using translucent filaments with higher TD values, such as the Polymaker Panchroma PLA Full Spectrum Bundle Pack (Translucent Yellow, Translucent Cyan, Translucent Magenta, and Translucent Grey). Snapmaker will also introduce official filaments optimized for color-mixing printing in future releases. Stay tuned for updates.
Usage Notes: Full Spectrum is currently in Beta. Print results may vary based on filament characteristics, model geometry, and slicing parameters. This feature is intended for creative color exploration and should not be relied upon for accurate color matching or reproduction. For detailed instructions, refer to the Full Spectrum Beta.
(1) Color Mixing
| Ratio | Supports mixing of two or three filament colors. |  |
| Cycle | Supports mixing by entering filament color codes. |  |
| Match | Supports matching mix effect to a target color. |  |
| Gradient | Supports creating a gradient effect by mixing two filament colors. |  |
(2) Subdivide Mixing Layers
| Subdivide mixing layers | When enabled, layer height for mixing areas will be subdivided for better color mixing results. |  |
| Full domain | When enabled, subdivided layer height applies to all mixed-color regions on outer walls, whether the colors are created by painting or filaments changes. |  |
| Apply subdivision to infill | When enabled, infill within mixed-color regions is subdivided using the same settings. |  |
- Added support for new filament types for the Snapmaker U1.
¶ Improvements
- Optimized the rib structure of the prime tower. A quadratic programming approach is used to constrain the rib area to a square shape, enhancing the stability of the prime tower during printing.
- Optimized printing from local files. The system can now correctly configure the filament-to-nozzle mapping even when the filament density is 0, preventing printing anomalies.
¶ Bug Fixes
- Fixed an issue where the first layer of the prime tower could exceed limits under certain process parameter configurations.
- Fixed a series of issues that could occur when a 3MF file contained more filaments than available extruders:
- Excess filaments could not be saved.
- Slicing could fail.
- Filament mapping between the software and the printer could be incorrect on the
Print Preprocessingpage.
- Fixed an issue where
UploadandUpload and Printwere unavailable when port 13619 was occupied by another process. - Fixed an issue where filament mapping could fail when starting a print directly from the built-in model library.
