Applications for X1 316i Metal 3D Printing
X1 316i Bronze impregnated stainless steel is a stainless steel and bronze composite material consisting of 60% stainless steel and 40% bronze. The material is very weak in magnetism and is suitable for applications that require a non-magnetic environment such as food and medical treatment. At the same time, bronze as a natural antibacterial agent, is conducive to the disinfection of parts. In addition, the material has a low yield strength, easy processing and polishing, and can be used for prototyping and small batch manufacturing of kitchen and bathroom products. The material also has enhanced corrosion resistance

Surface Finish
After sintering: ≈ 600 μin Ra (15 μm Ra )
Bead blasting: ≈ 300 μin Ra (7.5 μm Ra )
Barrel finishing: ≈ 50 μin Ra (1.25 μm Ra )
Post Processing
The X1 metal 420i needs to be cured after printing, and then bronze sintering penetration, and different workability and hardness can be obtained by adjusting the cooling temperature to meet the needs of different uses.

Finishes
X1 Metal 420i printed parts can achieve a density comparable to machined parts and can undergo subsequent machining or polishing.
Standard post-treatment involves removing the support structure during the printing process and using sandblasting to obtain a uniform surface.
When necessary, specific surface structures and features can be produced by CNC machining or polishing, but this needs to be evaluated according to the specific use requirements of the part.
In short, the 3D printed X1 metal 420i allows the production of high-density parts, which can be standard post-processing such as de-supporting and sandblasting, and can also be CNC finishing or polishing
Cost-saving Design Tips
To reduce the cost of X1 metal 420i 3D printing, you can consider the following:
- Follow the DFM principle in the design stage to ensure that there are enough powder holes inside the model.
- Optimize the model design and consider the support structure to prevent warping during printing.
- Reasonable design and limited post-processing capacity. X1 metal 420i is also prone to work hardening during post-treatment, increasing the difficulty and cost of processing.
- Streamline the model, rational use of materials, and minimize the waste of materials when printing.
- Consult experts if necessary to optimize the design scheme.
