A Metal jet nozzle and a forming system were developed in order to form three dimensional products. Ualloy of melting temperature 47℃ was used at first. The forming was conducted using the nozzle of 200μm and 50μm in diameter. The researchers could demonstrate the various kinds of products such as printed letters, drawn images, pyramidal products, 5storied Ragoda model, human face model, three-dimensional map.Next, the bonding strengths between metal drops were examined. The effect of the solidification, oxidation and direction of collision of drop on boning strength was clarified.At the second stage of this research, solder metal of melting temperature 183℃ was used. Bumps, two dimensional and three dimensional circuits were formed. In this process, the electric resistance of the circuit was investigated. The effect of the interval of ejection of metal drops on the electric resistance was clarified.At the third stage of this research, the metal of high melting temperature such as nickel (1455℃ m.p.), gold (1063℃ m.p.) was ejected successfully. So, the researchers could show the possibility of the generation of 3D functional structure by metal jet.

开发了一种金属喷射喷嘴和成形系统，以形成熔化温度为47℃的U合金，研究人员首先使用直径为200μm和50μm的喷嘴进行了成形。印刷字母、绘图图像、金字塔产品、五层 Ragoda 模型、人脸模型、三维地图等产品。接下来，检查金属滴之间的粘合强度。阐明了凝固、氧化和液滴碰撞方向对焊接强度的影响。在本研究的第二阶段，使用了熔化温度为183℃的焊料金属，在此过程中形成了二维和三维电路。 ，研究了电路的电阻，阐明了金属滴喷射间隔对电阻的影响。在本研究的第三阶段，研究了镍等高熔化温度的金属。 （1455℃ m.p.）、金（1063℃ m.p.）成功喷射，因此，研究人员可以展示通过金属射流生成3D功能结构的可能性。
