3D Printing Crowdsourcing to Help Hospitals Experiencing Supply Shortages Linked to COVID-19
As the virus continues to spread worldwide and breaks supply chains, 3D printers and expertise in additive manufacturing can lend a helping hand. Potential sources identify themselves using an online directory.
When a Northern Italian hospital needed a replacement valve for a reanimation device and the supplier had run out with no way to get more in a short time, a company in the area, Isinnova, had an immediate solution. After a phone call from Massimo Temporelli, founder of the FabLab in Milan, CEO Cristian Fracassie brought a 3D printer directly to the hospital, as the 3D Printing Media Network reports, and redesigned and then produced the missing piece.
After the first valves were 3D printed using a filament extrusion system, on location at the hospital, more valves were later 3D printed by another local firm, Lonati SpA, using a polymer laser powder bed fusion process (photo below) and a custom polyamide-based material.
Many people from around the globe have meanwhile reached out to offer help in producing these parts and others, donating their AM skills. In a public document hundreds of 3D printing professionals and hobbyists, companies, design engineers and doctors have signed up willing to share their printers or design expertise to help fill the gap in supply shortages linked to COVID-19.
Medical contract manufacturer Tangible Solutions shares a titanium 3D printed spine implant with an unusual lattice structure in this episode of The Cool Parts Show.
Hip stem implants must support the mechanical loads of the patient’s lifestyle, but should also avoid stress shielding. A team from Altair leveraged simulation, topology optimization and 3D printing to design an optimized hip stem that meets both conditions.
Jabil is getting ready for additive manufacturing to take its place as a production option in addition to conventional processes such as molding and machining. AM can and will fill this role, the company says — the focus now is on controlling cost and assuring quality and reliability.
