LET’S UNITED TO BATTLE AND OVERCOME COVID-19

Companies and people around the world are making use of the advanced digital manufacturing solutions to help battling COVID-19 while most of the conventional manufacturing factories are temporary closing for safety measures of social distancing.

Check out some of the case studies on how 3D Printing also known as additive manufacturing help during this COVID-19 pandemic.

*3D Systems Material Technology Overview Chart*
We have prepared a Material Technology Overview Chart to identify the best candidates for printer-material combinations for which either Class VI and/or ISO 10993 certifications are possible for COVID-19 applications, including potential solutions to the COVID-19 applications in emergency situations though the materials are not Class VI and/or ISO 10993 certified and customers should conduct their own testing to determine whether certification is possible.

FACE SHIELD FRAME

The Need

There is a shortage of Face Shields at hospitals for medical responders who are testing and treating COVID-19 patients. Medical responders need to be protected from respiratory droplets from coughing and sneezing. Even though many individuals and groups are designing and manufacturing face shield frames for these responders, many of the designs are not optimized for high-density optimized additive manufacturing and cannot be accessed locally.

The Solution

3D Systems have designed a face shield frame that is:

  • A downloadable file to enable local production using any Selective Laser Sintering (SLS) Printer
  • Optimized for high-density nesting
  • Made of medical-grade nylon that is autoclavable and compatible with disinfectant cleaners
  • Comfortable due to its flexible, non-rigid, form-fitting design
  • Compatible with bonnets and bouffants for protection of the forehead and eyes due to the retention tabs

The Outcome

This face shield frame has been manufactured using medical grade nylon on our SLS ProX 6100 machine. The design is a two-part flat pack design that will clip into each other to provide structure while minimizing material usage and maximizing the density of parts that can be manufactured on an SLS machine. At least 400 pairs of parts can fit in a build. They can be disassembled for cleaning.

VENTURI VENTILATOR VALVE

Challenge

For severe cases of COVID-19, patients require intensive care and oxygenation through the use of ventilators. With cases growing everyday around the world, venturi valves for ventilators are in short supply at hospitals.

The Solution

  1. Although there were venturi valves printed in Italy on the SLS ProX 6100 as a last minute solution, more testing is required to validate with newer open-source designs.
  2. We are exploring alternative materials and technologies that can be used for this application that are biocompatible and not reactive.

The Outcome

There was a clinical case where valves were 3D printed and used at a hospital in Chiari, Italy. Traditional OEMs were not able to supply them in such a short amount of time. Parts were reverse-engineered, prototyped, tested and printed in the span of 3 days on a SLS ProX 6100 with medical grade nylon.

LUNG ULTRASOUND

Challenge

Lung Ultrasound is considered an alternative to chest radiography or CT scanning in COVID-19 patients. It is safe, easy and quick for use at point-of-care, repeatable, low cost and radiation-free. Therefore, training physicians to rapidly acquire lung ultrasound skills can be critical for the success of COVID-19 management.

The Solution

Simbionix simulation allows for training to the full extent of the examination and includes practicing of the various lung zones, documentation and clinical reporting in a full clinical environment.

The Outcome

Our team is working around the clock to develop COVID-19 education and training content on the Simbionix U/S Mentor simulator. If you are a physician with relevant experience, we encourage you to join our development efforts.
