Metal Additive Manufacturing

Material Introduction


Additive manufacturing is a manufacturing technology that accumulates special materials layer by layer based on digital model files. This is carried out by means of extrusion, sintering, melting, light curing, and spraying, using software and numerical control systems to manufacture solid parts.

Fabrication Process


1Digital model design

Combines the usage requirements with additive manufacturing process characteristics to optimize digital models

2Prototype verification

Prototype verification is carried out to test the applicability of the process and its application.

3Batch production

Optimized design for batch production of parts

4 Post-processing

 

Further processing based on usage requirements and additive manufacturing processes (degreasing, sintering, hot isostatic pressing, etc.)

5Quality control

 

100% quality control based on application requirements.

 

 

Advantage


Rapid flexible prototyping without molds, great freedom in product design.

The manufacturing cycle is short, with low production costs for small batch parts.

Near net shape, small machining allowance and high material utilization.

Processed parts have higher structural strength and less processing stress concentration.

Used to make traditional hard-to-process materials (active metals, refractory metals and ceramics, etc.).
