How to 3D Print Stainless Steel

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

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

Step 2. Parameters are setting accurately on the SLM 3D printer. The first layer of stainless 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 stainless steel parts.

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

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

Frequently Asked Questions

1. How strong is 3D printed stainless steel?

Tests showed that under certain conditions the final 3D printed stainless steels were up to three times stronger than steels made by conventional techniques and yet still ductile, the scientists report today in Nature Materials.

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

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

5. What does 3D printed Stainless Steel look like?

Without any additional finish, 3D printed Stainless steel has a granular and rough surface texture. It is possible to obtain a shiny and smooth surface through finishes.

6. What kind of surface finishing can I get?

We will help you select the best post-processing strategy for your 3D printed stainless 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 hello@wenext.com.
