Snapmaker Orca 2.4.0 Alpha 发布公告本次 2.4.0 Alpha 版本新增模型选中高亮显示、LOD（Level of Detail）层级细节系统、混色匹配自动模式颜色选择、高流量热端（High-Flow Hot End）参数支持等功能，并新增 6 款耗材丝、扩充多款耗材颜色库，完整清单见下方更新日志。同时，本版本完成了 OpenSSL、macOS 构建环境、Flutter 三项底层依赖的大版本升级，涉及所有联网功能、内置网页与 macOS 安装包——诚挚欢迎参与 Alpha 测试，测试指引见更新日志之后。

一、新增项

新增模型选中高亮显示，优化交互选择体验。

选中模型时，显示最大包络框的同时，以白色高亮显示模型边缘。

在装配环境下，选中模型时，以黄色高亮显示模型边缘。

image

新增 LOD（Level of Detail）层级细节系统，提升复杂场景下的模型渲染效率。
混色匹配中的自动模式新增颜色选择功能，用户可选耗材颜色。

image

部分耗材与工艺新增高流量热端（High-Flow Hot End）参数支持，使用说明见:《U1 热端使用指南 ↗》。

新增多款耗材的颜色库：

Snapmaker PVA: 新增 1 个颜色
PETG Translucent: 新增 1 个颜色
Support for PLA: 新增 1 个颜色
Snapmaker PLA Rainbow: 新增 1 个颜色 (含5 个色值)
PLA Basic: 新增 2 个颜色
Snapmaker TPU: 新增 2 个颜色
PLA Full Spectrum: 新增 4 个颜色
Snapmaker PEBA 90A: 新增 5 个颜色
Snapmaker PLA Glow: 新增 5 个颜色
PLA Snapspeed: 新增 10 个颜色
PLA Silk: 新增 14 个颜色

二、优化项

整合并精简工艺预设列表。

为简化工艺选择流程，本次更新对 Snapmaker U1 的工艺预设进行了精简合并。部分同层高但不同品质等级的预设（如“Fine”“High Quality”）已统一整合为“Standard”预设。
详细映射关系见下表：

@Snapmaker U1 (0.8 nozzle) | | 0.56 Standard @Snapmaker U1 (0.8 nozzle) | 0.40mm Standard @Snapmaker U1 (0.8 nozzle) |

优化了较大模型在切片过程中的稳定性。
优化了 G-code 文件上传和打印的稳定性。
升级 OpenSSL 库至 3.5.7 版本，优化了网络通信的安全性与稳定性。
为“小区域流量补偿”功能的“流量补偿模型”参数增加了默认值，减少用户手动配置步骤。

三、修复项

修复使用 GitHub 登录成功后，页面异常显示接口响应内容的问题。
修复 Windows 系统下，设备熄屏后导致 Orca 与设备联机状态异常的问题。
修复 Orca 联机失败时弹出异常对话框的问题。
修复使用第三方授权登录成功后，仍重复弹出登录提示窗的问题。
修复连续登录 24 小时后，系统异常弹出重新登录提示的问题。
缓解了各平台在弱网环境下，首页、设备页及预打印页出现白屏的问题（仅在2.4.0及以上版本生效）。
修复 Snapmaker PETG HF 在 0.4 mm 喷嘴下无官方颜色配置的问题。
修复在 0.4 mm 喷嘴下，Snapmaker PETG HF 耗材点击色块时仍显示旧色盘的问题。
修复因配置文件(hints.ini)内容缺失导致软件无法启动的问题。

诚邀参与 Alpha 测试本次 2.4.0 Alpha 除新增一批功能（见上方更新日志）外，还完成了三项底层依赖的大版本升级——此类组件平时稳定运行、最易被忽视，也最难通过内部测试完全覆盖。

点击展开查看依赖升级清单

我们已在主流打印机型号上验证核心流程（导入 → 切片 → 发送打印 → 设备监控）可正常运行；但各类系统版本、旧固件、自建打印服务器、弱网等环境，仍需依靠真实使用加以覆盖。在非主流路径上遇到问题属于预期现象——每一条反馈都直接影响正式版质量，遇到问题请直接提交反馈，无需先行排查。

以下环境我们内部最难覆盖，诚挚欢迎相应设备的用户参与验证：

macOS 旧系统用户（本次构建环境为历次最新，旧系统是差异最大的组合），以及已升级 macOS 26 (Tahoe) 的用户（建议进行一轮快速验证）
弱网 / 企业网络 / 代理环境用户

三项升级可能引发的问题
