There have been many studies on three-dimensional (3D) printing using metal compounds. However, 3D printing using a metal compound has disadvantages in that it increases the cost for supplying metal materials. A method of using slag which is a recyclable material has been proposed to reduce costs. With the growing demand for additive manufacturing using by-products, slag has gained attention as a diverse recycling material for 3D printing technologies. A new fabrication approach was analyzed for producing porous bodies via additive manufacturing for blending slag and reinforced metals. However, because of its low quality due to low strength, low durability, and structural defeats, the amount of slag generated is high, and its usability remains uncertain. Also, slag is an excellent material with a huge potential for producing structures with high mechanical properties, and limited research in the area of slag recycling has been conducted due to difficulties in sintering the iron by-products. To develop a recycling approach that utilizes slag in 3D printing powders, a study to increase the industrial usability by mixing slag and ceramic beads was described. A method was presented to compare the physical properties of 3D printed slag parts with the physical properties of those generated by blending iron slag, alumina, and zirconia. In order to find the mixing ratio with the optimum physical properties, the average particle size, bending stress, and maximum compressive stress were tested. The combination ratio to obtain the highest strength was when iron slag powder was 40% and alumina was 60%. In addition, the specimens by composition to which the stress test was applied were cut to analyze the tissue under a microscope. It is thought that cracking in the sintered structure decreases and density increases by mixing alumina and zirconium, contributing to increased strength. When a ceramic bead composed of alumina and zirconium is mixed with slag to form a composite material, a metal compound having a level of physical properties that can be used as a material for 3D printing can be produced. Furthermore, a novel concept of producing lightweight structural materials via additive manufacturing, which entails a fabrication process whereby high-strength metals are stacked inside hollow base steels, was proposed.

对于使用金属化合物的三维（3D）打印，已有许多研究。然而，使用金属化合物的3D打印的缺点在于，其增加了供应金属材料的成本。为了降低成本，已经提出了使用作为可回收材料的炉渣的方法。随着对使用副产品进行增材制造的需求不断增长，矿渣作为3D打印技术的多样化回收材料已受到关注。分析了一种新的制造方法，该方法通过增材制造来混合矿渣和增强金属，从而制造多孔体。然而，由于其由于低强度，低耐久性和结构缺陷而导致的低质量，产生的炉渣量高，并且其可用性仍然不确定。也，炉渣是一种极好的材料，具有生产具有高机械性能的结构的巨大潜力，由于烧结铁副产物的困难，在炉渣回收领域的研究有限。为了开发一种在3D打印粉末中利用炉渣的回收方法，描述了一项通过混合炉渣和陶瓷珠来提高工业实用性的研究。提出了一种方法来比较3D打印的炉渣零件的物理性能与通过混合铁渣，氧化铝和氧化锆产生的那些物理性能。为了找到具有最佳物理性能的混合比，测试了平均粒径，弯曲应力和最大压缩应力。获得最高强度的配合比是铁渣粉为40％，氧化铝为60％时。此外，切下施加应力测试的成分的标本，以在显微镜下分析组织。据认为，通过混合氧化铝和锆，烧结结构中的裂纹减少并且密度增加，从而有助于提高强度。当将由氧化铝和锆组成的陶瓷珠与矿渣混合以形成复合材料时，可以生产出具有可用作3D打印材料的物理性能水平的金属化合物。此外，提出了一种通过增材制造来生产轻质结构材料的新颖概念，该概念涉及一种制造工艺，其中将高强度金属堆叠在空心基础钢内部。据认为，通过混合氧化铝和锆，烧结结构中的裂纹减少并且密度增加，从而有助于提高强度。当将由氧化铝和锆组成的陶瓷珠与矿渣混合以形成复合材料时，可以生产出具有可用作3D打印材料的物理性能水平的金属化合物。此外，提出了一种通过增材制造来生产轻质结构材料的新颖概念，该概念涉及一种制造工艺，其中将高强度金属堆叠在空心基础钢内部。据认为，通过混合氧化铝和锆，烧结结构中的裂纹减少并且密度增加，从而有助于提高强度。当将由氧化铝和锆组成的陶瓷珠与矿渣混合以形成复合材料时，可以生产出具有可用作3D打印材料的物理性能水平的金属化合物。此外，提出了一种通过增材制造来生产轻质结构材料的新颖概念，该概念涉及一种制造工艺，其中将高强度金属堆叠在空心基础钢内部。可以生产具有可用作3D打印材料的物理性能水平的金属化合物。此外，提出了一种通过增材制造来生产轻质结构材料的新颖概念，该概念涉及一种制造工艺，其中将高强度金属堆叠在空心基础钢内部。可以生产具有可用作3D打印材料的物理性能水平的金属化合物。此外，提出了一种通过增材制造来生产轻质结构材料的新颖概念，该概念涉及一种制造工艺，其中将高强度金属堆叠在空心基础钢内部。
