Laser-Melting Metal Additive Process The new laser-melting addi- tive-manufacturing process produces fully dense metal parts direct from 3D CAD data using a high-powered fiber laser. Parts are built in layers, in thicknesses ranging from 20 to 100 um, using a range of fine metal powders that are
fully melted in a tightly controlled atmosphere. The current range of machines uses a third-generation design that includes variable powder delivery, ultralow oxygen content in the build atmosphere and an unparalleled safe-change filter system to minimize user contact with materials. Two machines are available, the AM125 and the AM250, which feature vacu- um technology and low gas consumption in a rugged design. A touch-screen operator interface includes menu options for machine preparation and clean down. Consumable costs are minimized through features such as the soft recoater blade that can be rotated several times before replacement and uses low-cost filter elements to improve system reliability and cost of ownership. These additive-metal systems process a wide variety of materials including 316L and 17-4PH SS, H13 tool steel, aluminum Al-Si-12, titanium CP, Ti-6Al-4V and 7Nb, cobalt-chrome (ASTM75), and Inconel 718 and 625.

CT and DR
Software System New versions of computed tomogra- phy and digital radi- ography software— efX-CT 1.6 and efX-DR 1.0—focus on improving speed,
automation and image quality. Throughput capabilities have streamlined data acquisition control as well as extensive auto- mation features in the system calibration and image acquisi- tion steps. Image quality has been enhanced through updated beam-hardening correction algorithms and new features such as vorteX. VorteX is an automated single-pass computed tomography scanning technique using spiral acquisition and reconstruction with a digital flat-panel detector. The technique

was developed for the scanning of elongated objects that traditionally cannot fit into a single exposure. The scan does not require volume stitching and the object length is only lim- ited by the system scanning area. This technology improves throughput by making more efficient use of projection data.

3D Scanning System GoMeasure3D will demonstrate the new HDI Metrion 3D scanning system. The system was developed specifically for 3D inspection applications for quality assur- ance. It uses structured blue, green, or red light technology to capture 3D-scan data from physical objects in a single snap- shot. The scanner’s lighting technology filters out ambient lighting conditions in order to yield high accuracy and reli- able results. Each scanner includes proprietary 3D-scanning software to create digital 3D models that can be exported in PLY, OBJ, STL, ASC, and FBX geometry file formats. 3D3 Solutions Ph: 604-568 9638
