3D Printing for Metal Materials

Process：Selective Laser  Melting (SLM)

How It Works

High energy laser beam is used to melt the metal powder on the two-dimensional section after slicing of the 3D model, and the solid parts are printed layer by layer from bottom to top

Technical Features
•Metal appearance, prototype and functional parts is built directly
•Function parts with high dimension precision and high surface precision can be directly manufactured
•Functional parts with complex geometry, high density and high mechanical properties can be built directly
•Raw material powder usually do not need special configuration
Industries Applied

•Processing the appearance, assembly，support，functional prototypes of standard metals in aviation and aerospace, bio-medicine and mold industry 
•Single or small batch parts production, injection mold

Process：Electric Beam Melting(EBM)

How It Works

In vacuum environment, electron beam is used as heat source and metal powder is used as forming material. The metal parts are formed by scanning and melting the powder layer by layer

Technical Features
•High surface roughness 
•High forming efficiency 
•The ,micro-structure of built parts is more compact
•Metal parts with complex structure and excellent performance can be formed

Process：Wire and Arc Additive Manufacturing(WAAM)

How It Works

Taking welding arc of tungsten inert gas welding (TIG), melting inert gas welding (MIG) or plasma welding power  source (PA)  as heat source,  metal wire is melted  layer by layer  and accumulated to form the required  parts

Technical Features
•High melting efficiency 
•High utilization rate of wire material 
•Overall manufacturing lead time short
•Low cost

•Less restrictions on parts size

•The internal quality of the formed parts is good

•Suitable for forming large size parts

Process：Laser Solid Forming（LSF）

How It Works

With laser beam as the heat source, the metal powder is sent into the molten pool formed by laser on the forming surface synchronously and precisely through an automatic powder feeding device. As the laser spot moves, the powder is fed into the pool to melt and then solidify, form the desired shape

Technical Features
•Significantly improve the mechanical and corrosion resistance of the raw material 
•Fast manufacturing speed 
•High material utilization rates
•Lower manufacturing cost compared to traditionally way of manufacturing

•Can form large size metal parts
