Customized porous structures are widely used in bone tissue engineering as bone substitutes. In natural bone, the bone tissue relies on the blood vessels in the vesicular structure for nutrition supply. When a defect appears, the biomimetic porous scaffold becomes a good candidate for the formation of new blood vessels and helps bone tissue ingrowth. To construct an osteoconductive bone scaffold that is suitable for the defect region, the powder-based three-dimensional printing technology holds great promise, since it can deal with biocompatible, and biodegradable materials. In this mini-review, we introduce several types of powder-based manufacturing technologies and their corresponding printable materials for the construction of porous structures. In addition, some research cases are highlighted to illustrate the recent development of some research directions related to powder-based 3D printed bone scaffolds.

定制的多孔结构广泛用作骨组织工程中的骨替代物。在天然骨骼中，骨骼组织依赖于囊泡结构中的血管来提供营养。当出现缺陷时，仿生多孔支架将成为新血管形成的良好候选者，并有助于骨骼组织的向内生长。基于粉末的三维打印技术能够构建适用于缺损区域的骨传导性骨支架，因为它可以处理生物相容性和可生物降解的材料，因此具有广阔的前景。在此小型审查中，我们介绍了几种基于粉末的制造技术及其用于多孔结构构建的可打印材料。此外，
