Additive Manufacturing

3D printing has been recognized for its great potential with Additive Manufacturing(AM) since it was developed in the 1980s. Metal 3D printing refers to 3D printing using metal powder. It is attracting much attention because it can create very complicated shapes that can not be manufactured by conventional manufacturing processes such as casting, forging and machining. It can be applied to hard materials such as Titanium alloy and Inconel.

The Direct Energy Deposition(DED) method directly sprays metal powder on a irradiated heat source. While the Powder Bed Fusion(PBF) method selectively applies a heat source such as a laser to the desired site. Among them, the DED method is utilized to manufacture large products and where the existing products can be repaired or coated. The PBF method is used when a structural shape is difficult to manufacture due to the limitation of the manufacturing method. The PBF method has the advantage of making parts with complex shapes and securing high precision, but the process speed is relatively slow. Therefore, DED-type metal 3D printers and PBF-type metal 3D printers have mutually complementary relationships, and it is very important to select the best metal 3D printers according to the shape, size and quantity of parts to be produced.

​

We operate both DED and PBF type metal 3D printers so that we can select the optimal manufacturing process according to the size, shape, quantity and material type of the parts required by customers. In particular, unlike other domestic and foreign companies, DED and PBF type metal 3D printers have been developed with our own technology through joint research and development with POSTECH for 6 years. Therefore, we can select metal 3D printers suitable for customers’ needs and manufacture parts that meet customers' requirements even in special environments or conditions that are not supported by commercial metal 3D printers.

At present, our company manufactures parts of various materials such as Titanium alloy (Ti-6Al-4V), Inconel and Stainless Steel by using DED type 3D printer and PBF type 3D printer.
