MS1 Mold Steel 3D Printing Material Characteristics

3D printing metal powder mold steel MS1 contains the corresponding chemical composition 18% Ni Maraging 300 in the US, 1.2709 in Europe and X3NiCoMoTi 18-9-5 in Germany. This kind of steel is characterized by very good mechanical properties and is easily heat-treated. Use a simple heat aging hardening treatment to obtain excellent hardness and strength.

3D Printing Mold Advantages

3D printing molds are mainly used in mold conformal cooling waterways, special-shaped waterway mold inserts, and sliders, and are typically used in the manufacture of precision injection molds and die-casting molds. Has obvious feasible advantages:

• 1. Significantly reduce manufacturing costs, make the mold design cycle consistent with the product design cycle, reduce time and material consumption, and improve overall production efficiency;
• 2. Effectively reduce residual stress, prevent product warpage and deformation, and ensure dimensional accuracy;
• 3. The characteristic of 3D printing is that there are no restrictions on the shape, even if it is a complex shape and pipeline inside the object, that is to say, the mold conformal cooling water path can realize the design of the cooling channel of any shape, which greatly reduces the cooling time;
• 4. Compared with traditional mold manufacturing methods, 3D printing molds have a longer service life (millions of mold times) and higher production efficiency (the production cycle is shortened by 30%-70%);
