2. Metal3D3D Printing Technology Explained
2.1Technical Principles and Core Advantages
metal3DPrinting is done through*Selective Laser Melting (SLM)*or*Electron Beam Melting (EBM)*) technology, layer by layer accumulating metal powder to achieve moldless forming of complex geometric structures. Compared with traditional processing methods, its core advantages include:
-Revolutionary Design Freedom: Breaking through the limitations of traditional cutting and casting processes, it can manufacture highly complex components such as internal honeycomb structures and conformal cooling channels.
-High Material Efficiency: Material utilization rate reaches95%above, significantly reducing the loss cost of high-end alloys.
-Lightweight and Performance Optimization: Integrated molding reduces assembly interfaces and improves component strength, suitable for fields such as aerospace and medical devices that are sensitive to weight.
-Rapid Iteration Capability: The cycle from design to finished product is shortened by50%-70%accelerating product R&D and prototyping.
2.2Mainstream Processes and Applicable Scenarios
- SLM(Selective Laser Melting): Uses a high-power laser beam to melt metal powder, with accuracy up to ±0.05mm，suitable for small and medium-sized precision parts such as titanium alloys and stainless steel (such as dental implants and sensor housings).
- EBM(Electron Beam Melting): Uses an electron beam as a heat source in a vacuum environment, with high forming efficiency and low residual stress, suitable for large-size high-temperature alloy components (such as aero-engine blades).
- DED(Directed Energy Deposition): Used for large component repair or hybrid manufacturing, allowing for real-time material addition and compatible with titanium and nickel-based alloys.
2.3Typical Applications
-Aerospace: Lightweight cabin brackets, fuel nozzles, turbine blades, materials includeTC4Titanium alloy,Inconel 718high-temperature alloys.
-Medical and Health: Biocompatible titanium alloy bone implants, personalized surgical guides, meetASTM F136medical certification standards.
-Automotive Industry: Lightweight aluminum alloy structural parts, high-temperature resistant mold inserts, shortening the cooling cycle30%above.
-Energy Equipment: Nuclear power valve components, hydrogen fuel cell bipolar plates, using316Lstainless steel anti-corrosion solutions.
