DMT Ramps Up PPE Production

May 29, 2020

Since partnering with local nonprofit Maker Nexus seven weeks ago, the 3D printing experts in 爱豆传媒鈥檚 DMT Department have been busy.  Mike Appio, Department Chair, and a team of four DMT staffers have been running the Additive Manufacturing Lab鈥檚 3D printers seven days a week, 20 hours per day, to turn out parts for protective face shields. 

Maker Nexus donates and distributes the fabricated equipment to medical personnel throughout the Bay Area and beyond.  The initiative has rapidly evolved to high-volume production at and its army of more than 500 volunteer 鈥渕akers.鈥  To date, the Sunnyvale outfit has delivered over 40,000 of the shields, with orders pending for over 11,000 more.

鈥淚t鈥檚 been a big push and has demanded great teamwork from us, but we鈥檝e really nailed down a production flow that has enabled us to make over 1000 parts per week, week after week,鈥 says Appio. 

To date, the team, comprised of Additive Manufacturing Instructors Corey Dunsky and Brandon Boulden, CAD/AM Lab Coordinator Max Gilleland, and Machine Tool Technician Agustin Espino Diaz, has printed over 6,000 parts for Maker Nexus.

Recently, the team began using its laser cutter to pattern the transparent plastic sheets that provide the face shields鈥 protective barrier.  Maker Nexus鈥檚 success in transitioning production of several shield components to high-volume manufacturing processes has shifted demand for the 3D printed parts to other components, which are being fabricated by the volunteer maker community in large quantities. 

鈥淎s a result,鈥 team leader Dunsky notes, 鈥渢he laser cutting became the rate-limiting production step.  So Maker Nexus asked us to help with that, too.  We were able to respond quickly and have been cutting shields for four weeks.鈥  To date, the 爱豆传媒 team has delivered over 2,900 cut shields to its nonprofit partner.

Hose AdapterThis past two weeks, the group has again expanded its scope by 3D-printing a new device.  The device, designed by a Bay Area maker in cooperation with a local Kaiser hospital, is an adapter to be used in Powered Air-Purifying Respirators (PAPRs).  Unlike N95 masks, PAPR units are reusable and give their users complete protection from airborne liquids and particulates.

Many hospitals in the United States may have these systems stockpiled from the 2014 Ebola epidemic.  One of the most common is made by 3M, but the 2014-era hoods do not mate up with the connections on the newer 3M VersaFlo PAPR respirators.  The device now being fabricated in the DMT lab is an adapter that allows the older hoods to work with the new air supplies. 

With this design, hospitals with stockpiles of the older systems should be able to reuse them to protect doctors and nurses.  So far, the Kaiser system has requested at least 850 of the adapters and 爱豆传媒鈥檚 team has committed to printing 300 of them.

Hose AdapterDepartment head Appio explains, 鈥淥ur industrial 3D printers have capabilities that are particularly well-suited to making these parts, which have some precision details such as screw threads.  We鈥檝e verified that we鈥檙e able to make high-quality parts that the desktop machines, typically found in homes and maker spaces, struggle with.鈥

Foothill-爱豆传媒鈥檚 administration has been pleased that in this time of urgent need, the college鈥檚 3D printing educational resources have been rapidly pressed into service to the medical community. 

Appio sums up, 鈥淲e were able to demonstrate that the flexible equipment in our lab could be rapidly deployed to help out.  We鈥檙e participating in a national volunteer 3D printing initiative that was organized quickly, effectively calling on the Maker community to respond to the COVID PPE emergency.  Our department鈥檚 broad range of industrial and desktop printers, as well as our laser cutter, have seen a level of use in this high-production trial that we鈥檝e never experienced before, and both the equipment and the team have performed quite well.  Eventually, we鈥檒l use this experience to teach our students about the factors needed for success in scaling 3D printing to production levels.鈥 



DMT Producing PPE for Health Workers

April 6, 2020

爱豆传媒鈥檚 cutting-edge Design and Manufacturing Technologies program is using its 3D Printing capabilities to assist health care workers on the coronavirus front lines.

medical worker in face maskThe DMT Department is joining with a nonprofit group called that is producing transparent plastic face shields, using designs vetted by medical personnel. The shields are being delivered directly to workers at local hospitals and medical offices.

Face shields are among the types of personal protective equipment that are in short supply around the country, as health workers and emergency responders care for thousands of people who are infected with the new coronavirus.

Maker Nexus has already delivered hundreds of units to workers at Bay Area medical facilities, but it has a backlog of requests for thousands more.

3D printer with plastic headbands爱豆传媒鈥檚 DMT program started production work last week to make the plastic headbands that hold the transparent shields. The department is using equipment in its Additive Manufacturing Lab, including industrial 3D-printing machines and desktop 3D printers, according to Mike Appio, the department chair.

Department members 鈥 including instructors Corey Dunsky and Brandon Boulden and lab coordinator Max Gilleland 鈥 will operate the machines while closely observing health and safety protocols. These include social distancing, wearing appropriate protective equipment and regularly sterilizing all equipment and surfaces during the project.

"We know there's a critical need for this equipment,鈥 Appio said. 鈥淲e鈥檙e happy that we can use the De Anza College DMT program's equipment and skills to help with this effort."

Appio said the department has set an initial goal of producing 100 units each week. Visit to learn more about the face shield project or to support the effort.
