get linked access to Autodesk’s leading process simulation soft- ware, helping to ensure predictability and stability of selective laser melting (SLM) and direct energy deposition (DED) builds. This access control enables full traceability of production data and workflow information, helping to ensure immediate quality standards compliance.
“By linking Autodesk’s comprehensive additive and subtractive manufacturing solutions with Link3D’s production scheduler, we are excited to help Link3D provide a managed workflow from order intake to post-processing on the shop floor,” says Alexander Oster, director of additive manufacturing at Autodesk.

Toolkit for AM Design
Built upon the company’s GPU-powered geometry kernel, Dyndrite’s Additive Manufacturing Toolkit (AMT) equips software developers to design next-generation solutions. Capabilities include native CAD file import for maximum quality of 3D- printed output and an integrated-application programming interface for customizable scripting of interactive, automated workflows. The architecture, a horizontal, scalable solution, serves as a foundation for software developers. The toolkit report- edly provides for improved manufacturing execution systems, product data management and product lifecycle management,
topology optimization, simulation, and other predictive printing technologies that inform users of the printability of objects before and during production.

Acoustic Process-Monitoring Software
InfiniAM Sonic acoustic process monitoring software enables engineers to detect acoustic events within the AM build chamber, and turn this data into useful information about build quality.
The offering, installed into the RenAM 500Q system as a facto- ry-fit option, includes four acoustic energy sensors to detect vibration in the build. The sensors detect minute vibrations and collect these sound waves so that they can be heard, viewed and analyzed. Using four high-frequency sensors in different locations results in a slight time difference, due to the speed of sound.

The software uses this to triangulate the position of the noise on the build plate. In addition, the software presents a level of certainty regarding location and magnitude of the noise. This data can be combined graphically with other sensor data to build a comprehensive view of the part and the conditions at the time of build.
InfiniAM Sonic works alongside of InfiniAM Central and Infini- AM Spectral, for improved understanding of build quality and accelerated process development. Also available: the InfiniAM Central mobile app, which provides users with notifications on their build process in near real-time.
“The rapid heating and cooling that takes place during an AM build leads to residual stress in the part,” explains David Ewing, AM product manager at Renishaw. “While each laser weld results in a small amount of stress, residual stress can build up within the part, and if it increases past the strength of the metal it may lead to a fracture in the support material or part itself.
“The InfiniAM software suite makes it easier to understand what is happening during an AM build,” Ewing continues. “Spec- tral and Central give manufacturers eyes inside their AM com- ponent and build process, and InfiniAM Sonic provides the ears.” Renishaw: www.renishaw.com
Simulation Solution for Direct Energy Deposition
Simufact has introduced a dedicated simulation solution to help manufacturers improve DED metal AM processes. Offered as a module inside of Simufact Welding 2020 software, it enables the user to set up robust DED simulation models by importing existing tool paths direct from G-code instead of defining weld paths manually. The software evaluates the stresses, strains, dis- tortions, thermal history and hot spots during manufacturing to identify out-of-tolerance distortions, and recommends com- pensations. Based on this, the user can adapt the G-code to
