This small company making small engines sees big wins from metal AM in terms of both product performance and responsiveness to the market. Here, size isn’t a factor in succeeding with AM — the application instead shows how the capability is at its best when it can serve both production and design.
ExOne Using Metal 3D Printing with Controlled Porosity for Reusable Filters in Response to Coronavirus CrisisBy: Peter Zelinski
Collaboration with University of Pittsburgh applies binder jet to produce an alternative to disposable masks that are in short supply.
In the response to COVID-19, 3D printing demonstrated some of its strengths, but not all of them. However, the full effect of this crisis for AM is still to come.
In this week's update we discuss how additive manufacturing is supporting injection molding for masks, and ramping up to production quantities of face shields and testing swabs.

3D Printed Mask in Response to Coronavirus Crisis Passes Clinical Review — Multiplies Surgical Mask Stocks by 4XBy: Peter Zelinski
Reusable nylon mask made through powder bed fusion is easy to disinfect, uses replaceable filter media. Link to design file provided.
Editors Peter Zelinski and Stephanie Hendrixson discuss the pivot to production for 3D printed PPE, and other AM news in the fight against COVID-19.
Emergency authorization from FDA allows for use of device permitting four patients to use a shared ventilator. HP involved in mass production via additive manufacturing.
Ultrasonic additive manufacturing produces a build plate with embedded sensing, allowing for real-time measurement of the condition of the build. If a failure occurs during selective laser melting, this plate will reveal it immediately.
Editors Peter Zelinski and Stephanie Hendrixson discuss 3D printing issues related to ventilators, personal protective equipment (PPE) such as masks and face shields, and how business conditions have been affected by coronavirus.
A mask design is available online via freely available STL file. Hospital offers email address for 3D printing users able to help.
A build example involving an aircraft bracket illustrates the production rate increase resulting from more parts per build plus the elimination of support removal. A new system for quality monitoring aids production as well.
Can we achieve something like a wartime transition to ventilator production, or will the response need to look different from this?
