Special wire for additive manufacturing

3D printing is a process of forming a solid part by stacking raw materials (wires) through hundreds, thousands or even tens of thousands of layers through spatial trajectory planning, from scratch to the top. Its molding quality is inseparable from the choice of materials and processes.

In terms of materials, the composition, cleanliness, uniformity of wire diameter, surface quality, etc. of the materials are crucial. For wire 3D printing, traditional welding wires cannot meet the needs of 3D printing. Because welding is often used for connection, such as butt joints or corner joints between two plates, more attention is paid to the two-dimensional performance perpendicular to the weld direction, while 3D printing is three-dimensional, and it is necessary to pay attention to the performance of XYZ three-dimensional space or even any angle, which must be as homogeneous as possible. To reduce anisotropy, the control of wire composition and cleanliness are extremely high. Uneven wire diameter, surface scratches, oil stains, oxidation, etc. may cause defects such as slag inclusions and pores in the product preparation process, which ultimately affect the quality of the finished product.
