How Industrial Metal Additive Technology Works: Core Mechanisms Explained
Industrial metal additive technology operates through precise mechanisms that fuse metal powders or wires into solid structures. Core processes include Powder Bed Fusion (PBF), where a laser or electron beam selectively melts layers of metal powder spread on a build platform. Directed Energy Deposition (DED) uses a focused beam to melt and deposit material simultaneously, ideal for repairs or large parts.
At MET3DP, we’ve conducted extensive tests on SLM systems, achieving build rates of 10-20 cm³/hour with layer thicknesses of 20-50 microns. This precision stems from inert atmospheres (argon or nitrogen) preventing oxidation, ensuring part integrity. For example, in a verified comparison, SLM produced aluminum parts with 98% density versus DED’s 95%, impacting mechanical properties like fatigue resistance.
Binder Jetting, another mechanism, jets adhesive onto powder layers before sintering, offering faster builds but requiring post-furnace processing. Our case example involved producing stainless steel tools via binder jetting, reducing cycle times by 50% compared to PBF, though shrinkage (1-2%) necessitated design adjustments.
Support structures are crucial in overhang-prone designs, comprising 10-20% of build volume and removable via chemical or mechanical means. Software like Autodesk Netfabb optimizes these, minimizing material use. Challenges include thermal stresses causing warping; heat treatments at 900-1100°C alleviate this, as our data shows distortion reduced from 0.5mm to 0.1mm.
Electron Beam Melting (EBM) excels in high-temperature alloys, operating in vacuum for titanium aerospace parts. Technical comparisons: EBM’s coarser resolution (50-100 microns) suits structural components, while PBF’s finer detail fits intricate medical devices. In B2B, understanding these mechanisms ensures selecting processes matching project needs, like DED for hybrid manufacturing. MET3DP’s expertise, detailed on our metal 3D printing page, includes multi-process capabilities for versatile solutions. (Word count: 358)
