Snapmaker Orca V2.3.3 Release

New Features

1. Introduced Full Spectrum printing.
   (1) Color Mixing

Ratio	Ratio	Cycle	Match	Gradient
Supports mixing of two or three filament colors	Support mixing of two or three filament colors	Supports mixing by entering filament color codes	Supports matching mix effect to a target color	Supports creating a gradient effect by mixing two filament colors

(2) Subdivide Mixing Layers

Subdivide mixing layers	Full domain	Apply subdivision to infill
When enabled, layer height for mixing areas will be subdivided for better color mixing results.	When enabled, subdivided layer height applies to all mixed-color regions on outer walls, whether the colors are created by painting or filaments changes.	When enabled, infill within mixed-color regions is subdivided using the same settings.

2. Added support for new filament types for the Snapmaker U1.

Improvements

1. 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.

2. 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

1. Fixed an issue where the first layer of the prime tower could exceed limits under certain process parameter configurations.

2. Fixed a series of issues that could occur when a 3MF file contained more filaments than available extruders:
   (1) Excess filaments could not be saved.

(2) Slicing could fail.

(3) Filament mapping between the software and the printer could be incorrect on the Print Preprocessing page.

3. Fixed an issue where Upload and Upload and Print were unavailable when port 13619 was occupied by another process.

4. Fixed an issue where filament mapping could fail when starting a print directly from the built-in model library.

新增项

1. 新增全彩打印（Full Spectrum）特性。

（1）混色功能

比例模式	比例模式	循环模式	匹配模式	渐变模式
支持两种或三种耗材颜色混合	支持通过输入耗材编号进行混合		支持基于目标颜色匹配混色效果	支持两种耗材颜色混合形成渐变效果

（2）混色细分层高

混色细分层高	全域生效	应用到填充
启用后，混色区域的层高将被细分，以实现更好的混色效果。	启用后，通过涂色或更换耗材丝为模型上色，细分层高将对所有外墙的混色区域生效。	启用后，对混色区域内的填充部分进行相同的细分处理。

2. 新增适配 Snapmaker U1 的耗材种类。

优化项

1. 优化擦拭塔的肋条（Rib）结构。采用二次规划的方法，将 Rib 区域的形状约束为正方形，以增强擦拭塔在打印过程中的稳定性。

2. 优化从设备本地文件发起打印的功能。当耗材密度为 0 时，系统仍能正确设置打印喷嘴映射，避免出现打印异常。

修复项

1. 修复在某些工艺参数配置下，擦拭塔首层超限的问题。

2. 修复 3MF 文件中耗材数量超过挤出机数量而引发的一系列问题：
   （1）超出部分的耗材无法保存；

（2）可能导致切片失败；

（3）在预打印页面中，软件与设备的耗材映射出错。

3. 修复当 13619 端口被其他进程占用时，无法点击上传或上传并打印的问题。

4. 修复从内置模型库直接发起打印时，耗材映射失效的问题。
