What is SLM 3D Printing?

SLM (Selective Laser Melting) is an additive printing technology. It completely melts metal powder through laser and then builds metal parts layer by layer. The accuracy of parts printed by slm is generally ±0.3mm, and it can reach up to ±0.2mm through precision processing methods.

During the printing process of SLM, as it melts powder to build products, the structure between metals is completely integrated when forming the shape of each layer. The products manufactured are also high-strength parts, which is why it is popular in the automotive and aerospace industries.

The process of SLM 3D printing mainly consists of five stages: design, preparation, laser melting, layer-by-layer construction and post-processing. Post-treatment is required because the surface of the products produced by SLM may have a somewhat rough feeling. Polishing or electrochemical treatment can improve the surface smoothness.

The Advantages of SLM 3D Printing

Material Diversity

Supports a variety of metal alloy materials to meet the demand for high-strength parts in industries such as aerospace and automobiles.

Complex Shape

It can create internal channels, hollow structures and complex shapes that are difficult to achieve with other 3D printing.

Fast Delivery Cycle

No additional custom molds are required, significantly shortening the cycle from design to finished product and accelerating the market launch of your products.

Customized Parts

Suitable for the production of small-batch and personalized parts, it meets the customization requirements.

Future Parts 3D Printing Solution

Prototype Design

3D Printing

It is used for making models with complex structures that do not require mold opening. We use 3D printing to meet the rapid iteration and verification requirements of your products in the early design stage, helping you shorten the development cycle and reduce the cost of prototyping.

Low Volume Production

Vacuum Casting

It is suitable for small-batch manufacturing and can quickly replicate the details and appearance of 3D printed parts. Vacuum casting is used to achieve stable output of functional samples or appearance parts without large-scale mold opening.

High Volume Production

Injection Molding

It is used in the mass production stage where high dimensional accuracy and consistency are required. We adopt the injection molding process to achieve the official mass production of the products, ensuring product quality, production efficiency and cost control.
