2A 3D printing: the cutting edge of technology

Embracing the future: How Wallet pioneered the frontier of 2A metal 3D printing

Driven by continued innovation in additive manufacturing, the manufacturing landscape is undergoing dramatic changes, especially in the field of metal parts. One of the most transformative technologies at the forefront is Selective Laser Melting (SLM), often included under the broader term "2A" (Additive Manufacturing for Advanced Applications). For boundary-pushing engineers, designers and innovators, leveraging this technology effectively requires more than a printer; it requires expertise, sophisticated infrastructure and seamless post-processing. This is what makes GreatLight, China’s leading rapid prototyping company, unique.

Understanding the Power Source: SLM Technology

Essentially, SLM is a powder bed fusion technology that revolutionizes the manufacturing of metal parts:

1. Laser accuracy: A high-power laser beam selectively melts layers of ultra-fine metal powder based on complex digital CAD models.
2. Build layer by layer: Successive layers are deposited and fused, carefully constructing complex geometries not possible with traditional subtractive methods.
3. Material integrity: Intense laser energy creates fully dense metal parts with mechanical properties that often rival, and in some cases exceed, forged materials.

This technology unlocks unprecedented design freedom—consider internal cooling channels, lightweight lattice structures, topology-optimized components, and the integration of components into a single printed part.
