【摘要】 3D打印技术兼具材料、结构及功能一体化设计制造成形的特征，尤其是以数字微滴喷射工艺为基础的3DP工艺，因其能实现多种材料的可控定量定点喷射沉积，能制作出不同组分和按需分布的多材料异质零件，因此在异质零件的成形方面具有独特优势。基于此，介绍了以数字微喷工艺为核心的3D打印技术制作异质零件的成形方法及成形工艺。更多还原

【Abstract】 3 D printing technology has the characteristics of integrated design, manufacture and forming of materials, structures and functions, especially the 3 DP process based on the digital droplet jetting process.Because it can realize the controllable quantitative fixed-point jet deposition of various materials, and can produce multi-material heterogeneous parts with different components and on-demand distribution, so it has unique advantages in the forming of heterogeneous parts. Based on this, the forming method and forming process of 3 D printing technology with digital micro-jet technology as the core to make heterogeneous parts are introduced.更多还原
