TECH REVIEW additivemanufacturing.media 37 CAD File Preparation Software for AM Systems Renishaw's QuantAM fle preparation software tool prepares models from STL data for production in the company's additive manufacturing systems. The tool integrates into the Renishaw machine control software and enables users to accurately and quickly review all build fles, including those from third-party packages. The software can also be used to guide the design for additive manu- facturing (DfAM) process. QuantAM accepts CAD exports in the form of STL data and locks process parameters for each build to the CAD model data for consistent processing and traceability. Users can orient the part, apply support anchors, position multiple components and check the build simulation before export within the software. It is possible to review the geometry and laser tool path slice by slice, as well as discrete laser exposure within each slice. A material development module with CSV data import enables importing materials devel- opment arrays, and the soft- ware supports copying and editing materials fles. renishaw.com DMLS Machine Enables Cost-Efcient Small Batch Production The EOS M 100 direct metal laser sintering (DMLS) machine is intended for users entering additive manufacturing. With its small build volume, based on a round, 100-mm-diameter build platform, the system is designed for cost-efcient production of small quantities of parts, such as dental crowns and bridges. The machine is capable of processing EOS CobaltChrome SP2 and EOS StainlessSteel 316L. EOS Titanium Ti64 is still in the development stage, and will be the next material available for the system, the company says. The system features a 200-W fber laser and a smaller laser spot with good detail resolution, making it possible to produce complex and delicate compo- nents on the system. Efcient recoating and exposure reduces nonproductive time and contributes to the efcient production of smaller quantities. According to EOS, materials can be replaced easily and maintenance performed quickly. Ease of material handling and component change-over is said to reduce setup times, increase productivity and improve operator safety. eos.info Closed-Loop Control Introduced for EBAM Sciaky Inc., a subsidiary of Phillips Service Industries Inc. (PSI) and provider of metal additive manufac- turing (AM) solutions, has introduced a closed-loop control called IRISS for its Electron Beam Additive Manufac- turing (EBAM) systems. IRISS, which stands for Interlayer Real-time Imaging & Sensing System, is said to provide consis- tent process control for part geometry, mechanical properties, microstructure and metal chemistry for large-scale 3D-printed parts. The closed-loop control, only available for Sciaky EBAM systems, monitors the metal deposition pro- cess in real time and makes adjustments to the process parame- ters that compensate for variation through- out the build process. EBAM systems utilize wire feedstock, which is available in a variety of metals such as titanium, tantalum, niobium, tungsten, molyb- denum, Inconel, aluminum, stainless steels and nickel alloys. Sciaky's scalable EBAM systems can produce parts ranging from 8" to 19 ft. (203 mm to 5.79 m) in length and ofer gross metal deposition rates ranging from 7 to 20 lbs/hr. (3.18 to 9.07 kg/hr.). With the dual wirefeed option, it is possible to com- bine two diferent metal alloys into a single melt pool to create custom al- loy parts, or change the mixture ratio to create graded parts or structures. sciaky.com
