The ASTM has designated two process categories for metal additive manufacturing (AM), directed energy deposition (DED) and powder bed fusion. DED processes build shapes bead by bead, layer by layer, using robotic or CNC systems via computer-aided modeling (CAM) software with either wire, powder, or some combination of these consumables. There are multiple processes used in DED systems including electron beam, laser, gas metal arc, gas tungsten arc, and plasma arc. Robotic DED offers more flexibility, range in motion, and maximum build volume for large structures or adding features to existing components. 

Arc welding is a well-established joining process. Robotic arc CAM supports agile welding, cladding, and DED to create large AM components using digital manufacturing. It can also be used to enable additive manufacturing of features onto existing structures, such as castings, forgings, plate, and pipe. This, in turn, provides a wide range of benefits for optimizing design, small batch manufacturing, shortened lead times, decreased factory footprints, reduced material usage, and improved properties over castings.

EWI has developed expertise in the following areas: digital
data workflow (DDW), basic and advanced robotic DED AM, parametric models for
process-consumable combinations, process-feature-property models, and
representative qualifications for components. These capabilities enable EWI to develop
sound AM components ensuring a quality first approach. Components then can be
produced to near net shape like the propeller blade shown to the right.

In addition to the competencies above, EWI provides solutions that range from supporting concept component design through optimization for manufacturing and demonstration-validation testing into low-rate production. EWI has a diverse array of DED systems, unique expertise in metal DED (arc, laser, electron beam) processes, and pathways for qualification of the additive manufacturing structures and parts. For robotic DED systems, EWI has multiple test beds, including Yaskawa Motoman, OTC DAIHEN, CLOOS, FANUC, and ABB. This allows the component to be prototyped on system platforms that will be used in production making a transition from prototype to production simpler.

EWI is pleased to announce three upcoming webinars in February:

• Introduction to Metal Additive Manufacturing (AM)
  Wednesday, February 10, 2021, 2:00-3:30pm EST
  EWI additive manufacturing specialists Ajay Krishnan and Aaron Wertz will present a concise overview of metal AM plus its applications, business cases, value propositions, materials, and design considerations. This 90-minute seminar will allow time for Q&A at the end.

• The Intersection Between Automation and Factory 4.0.
  Tuesday, February 16, 2021, 1:00-2:00pm EST
  This panel discussion, presented by EWI Advisory Services, will examine two emerging technology innovations in manufacturing, the Internet of Things and advanced automation. Dominic Myers, EWI Innovation Advisory Director, and Dhaval Sahija, Enterprise Solutions Manager for Softweb Solutions (an Avnet Company), will discuss how these game-changing forces will come together to form the factories of the future.

• Evaluating the Feasibility of 3D-printed Parts for Medical Pressure-related Devices
  Wednesday, February 24, 2021, 12:00-12:45pm EST
  Early in the COVID pandemic, critical life support machines were in high demand and short supply. Hospitals, especially in remote locations, had difficulty obtaining needed parts for ventilators. To help address this crisis, EWI conducted a rapid project to determine the feasibility of using 3D-printed parts to meet demand in the short term near the point of care. EWI Senior Technology Leader Jeff Ellis and ASTM AM Center of Excellence Director Dan Kowalik will share EWI’s successful results and other potential applications. Lewis Crenhsaw, an FDA EUA submission specialist from TC Medical, will also share tips on requirements and emergency filings.

These programs are free and open to the public, but registration is required in advance. To sign up for one or more of these events, simply click below:

The post Introduction to Metal AM Processes – a new EWI guide appeared first on EWI.

By Henry Cialone
President & CEO, EWI

In late October, I wrote about how EWI is contributing to advances in the electric vehicle (EV) industry through a new, innovative methodology for crash test simulations. What I didn’t say in that article is that EV crash test simulation is just one area in which we are using data science to make things better in our everyday lives and to create value for our clients, their customers, and manufacturing in general.

I’m excited about every one of EWI’s efforts to inventively apply data science to today’s manufacturing challenges and look forward to sharing details about more of those initiatives in the coming months. Right now, though, I’d like to clarify what I mean by the term “data science” and let you know how we’re applying it to improve manufacturing…
