Our Mold Steel Material

We offer mold steel CX for SLM 3D Printing. Mold steel CX is a good corrosion resistance material that heat treatment will not affect too much on manufactured parts. CX steel is mainly suitable for injection mold and mold conformal cooling channel printing, and other industrial applications where high strength and hardness are required.

How to 3D Print Mold Steel?

We utilize SLM which belongs to powder bed fusion technology to print mold steel parts:


Step 1. Prepare STL files for mold steel parts. Convert STL files into G-code through slicer program.


Parameters are setting accurately on the SLM 3D printer. The first layer of mold steel powder is rolling down by the powder roller, while the laser light selects an area and melt and fuse the powders together.


Step 3. The printing bed is moving downward, and the roller rolls down a new layer of material, and the laser light keeps melting and fusing the selective area. The process repeats until final parts are shaped.


Step 4. Takes time for cooling down build chamber and 3D printed mold steel parts.


Step 5. Take the mold steel parts out of build chamber and remove residual powders on the printed parts.


Step 6. Send the mold steel parts to post-processing for better surface, higher mechanical properties, etc.

Frequently Asked Questions

1. What is mold steels?

Mold steels is for molds manufacturing, such as cold-punching molds, hot forging dies, die-casting molds, and others.

2. How much does it cost to 3D print mold steel?

Cost of mold steel 3D Printing depends on factors such as the part volumes, complexity and the types of post-processing you need. Get an instant quote here.

3. Can I print moving parts with mold steel?

As SLM metal 3D printing is very hard to clean residual powders in deep, narrow and hard to reach places, printing moving parts with mold steel is not recommended.

4. Which technology is used to 3D print mold steel parts?

Mold steel can be 3D printed with SLM and DMLS metal 3D Printing. At Wenext, we offer SLM 3D Printing to print mold steel parts.

5. What kind of surface finishing can I get?

We will help you select the best post-processing strategy for your 3D printed mold steel part, and we offer surface finishing including polishing, grinding, turning, milling, threading, heat treatment, etc. For more selections, please contact our Customer Success Manger or email
