Column - The Appeal of Digital Metal: "Precision Manufacturing of Small Parts"
ヘガネスジャパン
The features of Digital Metal can be summarized as follows: - Capable of precisely shaping small parts - High design freedom - Good surface quality - Suitable for mass production - Capable of shape changes and customization This time, I would like to pick up on "capable of precisely shaping small parts." A well-known test data for 3D printers is the chess piece rook. It is very difficult to shape this 3D form, which has fine spiral stairs inside, according to the data using conventional methods. However, Digital Metal's binder jetting technology can precisely shape this form in metal. In the photo, rooks are shaped in different sizes ranging from 3mm to 30mm (made of 316L). Of course, the smallest rook also has spiral stairs shaped inside. Digital Metal specializes in relatively small parts that fit within a size of about 50mm cubic. For small parts, a size of approximately 1x1x3mm is recommended. With advancements in technology, the shaping size has gradually expanded, and depending on the shape, parts up to about 80 to 150mm in size have become possible to shape.
