I. 導入: 金属積層造形 3D プリント


Metal additive manufacturing 3D printing is a process of creating three-dimensional objects by adding layers of metal powder and using heat or high-powered lasers to bond the layers together. This technology is also called metal 3D printing, and it has become a game-changer in the world of manufacturing, allowing for the production of complex geometries and designs not achievable with traditional manufacturing techniques.

II. Metal Additive Manufacturing Techniques


There are three primary metal additive manufacturing techniques: 粉末床融合 (PBF), 指向性エネルギー堆積 (DED), and Binder Jetting (BJ). PBF and DED are the two primary metal 3D printing techniques used in industry.

a. 粉末床融合 (PBF)
粉末床融合 (PBF) is a process of fusing metal powder by using high-powered lasers to melt the powder and create a solid part. PBF can be further divided into two technologies: 選択的レーザー溶融 (SLM) 電子ビーム溶解と (EBM).

b. 指向性エネルギー堆積 (DED)
指向性エネルギー堆積 (DED) uses a high-powered laser or electron beam to create melted metal that is then directly deposited onto a part. DED can be divided into two technologies: レーザー金属蒸着 (LMD) and Electron Beam Welding (EBW).

c. バインダージェッティング (BJ)
バインダージェッティング (BJ) creates a part by layering metal powder with a binder material that forms a solid object. The binder material holds the metal powder together until it is melted together to create a solid part.

III. Types of Metal Powders Used in 3D Printing


Different types of metal powders are used in 3D printing, including titanium powder, stainless steel powder, cobalt chromium powder, aluminum powder, and more.

a. Titanium Powder
Titanium powder is used to produce parts with excellent strength and excellent corrosion resistance, making it suitable for medical implants and aerospace applications.

b. Stainless Steel Powder
Stainless steel powder is used to create parts with high temperature and corrosion resistance, making it suitable for industrial and manufacturing applications.

c. Cobalt Chromium Powder
Cobalt chromium powder is used to produce parts with high tensile strength and good corrosion resistance, making it suitable for dental and medical implant applications.

d. Aluminum Powder
Aluminum powder is used to create parts with a high strength-to-weight ratio, making it suitable for aerospace and automotive applications.

IV. Making Metal Powder for 3D Printing


Making metal powder for 3D printing involves several processes, including atomization, electrolysis, and chemical reduction.

a. Atomization
Atomization is a process that involves melting a metal and then spreading it out over a large surface to solidify and form small particles.

b. Electrolysis
Electrolysis involves passing an electric current through a metal salt solution to create pure metal powders.

c. Chemical Reduction
Chemical reduction involves using chemicals to reduce the metal components into their pure forms, producing high-purity metal powders.

V. Difference Between Additive Manufacturing and 3D Printing


The terms “additive manufacturing” and “3D printing” are frequently used interchangeably. しかし, they are not the same thing. Additive manufacturing is a broad term that refers to the process of creating three-dimensional objects by adding material layer by layer. 3D印刷, 一方で, is a subcategory of additive manufacturing that involves printing three-dimensional objects using a 3D printer.

VI. Advantages of Metal Additive Manufacturing


The advantages of metal additive manufacturing are numerous, including the ability to produce complex geometries and intricate designs not achievable with traditional manufacturing techniques, the reduction of waste production, and the ability to customize parts according to specific requirements . さらに, 3D printing allows for the production of parts with high strength-to-weight ratios, reducing overall weight and cost. さらに, 3D printing allows for ラピッドプロトタイピング, reducing the time and cost of product development.

VII. Applications of Metal 3D Printing in Industry


The applications of metal 3D printing in industry are vast and diverse. One significant application is in the aerospace industry, where 3D printing allows for the production of lightweight parts that reduce fuel consumption, lower emissions, and provide a more efficient aircraft. The medical industry also uses 3D printing to produce customized implants that fit a patient’s specific anatomy, leading to faster healing and better outcomes.

Another critical application area is in the automotive industry, where 3D printing enables the production of customized parts and the creation of complex geometries that are not achievable with traditional manufacturing methods. The oil and gas industry uses 3D printing to create parts for tough operating conditions were traditional manufacturing processes fail to provide adequate solutions.

さらに, 3D printing is used in the jewelry industry to create bespoke pieces and unique designs, while the architecture and construction industries use this technology to produce scale models and full-scale building components.

VIII. 結論


Metal additive manufacturing 3D printing is a highly innovative technology that offers numerous advantages, 含む ラピッドプロトタイピング, customized products, complex geometries, and reduced waste production. The applications of metal 3D printing in industry are vast and diverse, with aerospace, 自動車, 医学, and other industries benefiting from this technology. By understanding the different techniques and processes involved in metal additive manufacturing 3D printing, we can unlock the full potential of this technology and continue to advance manufacturing capabilities and efficiency.
