these machines employ supersonic deposition, where a nozzle accelerates air to as much as three times the speed of sound to deposit injected powders onto a substrate attached to a six-axis robotic arm. The kinetic energy of the particles, explain company officials, causes the powders to bind together to form a high- density part with normal metallurgical properties. www.spee3D.com
Product Development via Computational Engineering
nTopology’s computational-engineering approach to creating complex designs relies on implicit modeling using a unified, purely algorithm-based environment for processing geometry, simulation, and manufacturing rules and outputs through a sin- gle, highly automated platform. Design teams can overlay com-
ature change, and are capable of scanning speeds in excess of 8 in./sec. The base of the Equator 500 supports workpiece and fixturing with a total weight limit of 221 lb. The ratio of gauging volume to footprint means that the machine is space efficient— with a footprint of 36.2 in. by 36.4 in., the 500 fits alongside pro- duction machines. Typical applications include car and truck transmission and engine casings, drive-train parts, suspension castings, pressed parts, valves, and pumps. www.renishaw.com/equator500
Design and Engineering Software with Powerful Sim. Capabilities
Altair Engineering showcased its design and engineering soft- ware, including comprehensive simulation capabilities. These are consolidated in the newly released HyperWorks 2019, a compre- hensive open-architecture simulation platform that, as the com- pany demonstrated at RAPID + TCT, unifies design, engineering and manufacturing communities for faster development cycles.
The 2019 version of this simulation- and AI-driven product- development platform expands on the number of solutions avail- able for designers and engineers to speed decision-making and time to market, including user-experience advancements and intuitive workflows.
Highlights include expanded nonlinear solver functionality through Altair OptiStruct, ideal for users performing stiffness, strength and fatigue-life simulations. The single-model, multi- attribute workflow enabled by OptiStruct enables design decisions to be made quickly by engineers performing linear, nonlinear, and durability analysis—using one optimization-ready model.
HyperWorks 2019 also includes SimSolid for rapid simulation of complex assemblies; HyperLife for simple-to-learn fatigue- life prediction; SimLab, an intuitive workflow platform for sim- ulating multiphysics problems; and HyperMesh for generation of large, complex finite element models.
In addition, Altair Inspire, included in the HyperWorks platform, provides a generative design/topology-optimization and rapid simulation solution for design engineers. It enhances the concept development process, according to company officials, by enabling simulation-driven design to increase a product’s efficiency, strength and manufacturability, leading to reduced costs, devel- opment time, material consumption and product weight. www.altair.com/HW2019 3DMP

Gauging System for Large Parts
Building on the success of its Equator 300 gauging system, Renishaw introduced its Equator 500 for larger parts, with a working volume to 20 in. dia. and to 16 in. tall. Both the 300 and 500 stay accurate between 41 F and 122 F at any rate of temper-
