Die Steel 3D Printing Services

Die Steel 3D Printing Service is very popular in rapid prototyping. Die steel is  widely used in the manufacturing of tooling elements such as cores and inserts of die casting and injection moulding tools. The 3D printing metal powder, EOS Maraging Steel MS1, which is a fine powder form of maraging steel. The composition of MS1 mold steel corresponds to American classification standard 18 maraging steel 300, European 1.2709 and German X3NCoMoTi18-9-5. This steel is characterized by very good mechanical properties, and can be  heat treated easily. The excellent hardness and strength can be earned by using a simple heat age hardening treatment. The parts made of MS1 die steel have good machinability, and the hardness that can be obtained by age hardening is about 55HRC. This steel is commonly used in complex tools, but also in high-performance industrial products such as in aerospace applications.

Why choose die steel in 3D printing service?

Why choose the die steel for 3D printing? Because the die steel has excellent hardness, wear resistance and deformation resistance, as well as the ability to maintain the cutting edge at high temperature.

Die H13 hot work tool steel is one of them, which can withstand process conditions of indefinite time.

Besides, the Martensite steel, which is used for special die, is also belong to the tool steel material. For example, the martensite 300, is also called mar-aging steel, and is well known by its' high strength, toughness and dimensional stability in the aging process.

These martensite steel are different from other steels, because they are carbon-free and belong to inter-metallic compounds, which are hardened by the metallurgical reaction of rich nickel, cobalt and molybdenum. Due to its high hardness and wear resistance, Martensite 300 is suitable for many mold applications. Such as injection molds, light metal alloy casting, stamping and extrusion, etc. 

The Advantage of 3D printing Molds

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

1. Significantly reduce the manufacturing cost, make the mold design cycle consistent with the product design cycle, reduce time and material consumption, thereby improving the overall production efficiency;

2. Effectively reduce residual stress, prevent product warping and deformation, and ensure dimensional accuracy;

3. The feature of 3D printing is that there is no restriction on modeling, even for complex modeling and pipelines in the object. That is to say, the mold conformal cooling water channel can realize the cooling channel design of any shape, which greatly reduces the cooling time;

4. Compared with traditional mold manufacturing methods, 3D printing molds have longer service life (millions of molds) and higher production efficiency (production cycle shortened by 30%-70%);


3D printing mold process

Mold optimization design → mold flow analysis → 3D printing feasibility analysis → laser sintering 3D printing manufacturing → high temperature tempering, polishing and other follow-up treatments.

In this way, the metal powder of die steel is widely used in 3D printing.components.
