提出了一种个性化医学模型间接制造方案——将混色FDM3D打印技术和DLP面曝光3D打印技术相结合，能够完整保留医疗模型的外部轮廓特征和内部实体结构；同层换色FDM混色打印技术方案，可以实现内部复杂结构模型的彩色打印，具有多色彩突出、透明并易于观察内部结构的特征。基于本方案进行了复杂心脏结构的彩色打印验证，打印精度和颜色逼真度均符合要求，显示了该方案在医疗模型低成本制造上的应用潜力。

This paper proposes a personalized medical model indirect manufacturing scheme that combines mixed-color FDM 3D printing technology with DLP surface exposure 3D printing technology. This approach can fully retain the external contour features and internal solid structure of the medical model. The proposed same-layer mixed-color FDM printing technology scheme enables color printing of internal complex structure models, with multiple colors and transparent observation of internal structures. A complex cardiac structure was printed and verified using the proposed scheme, demonstrating high printing accuracy and color fidelity. This highlights the potential of the proposed scheme in low-cost manufacturing of medical models.
