The UChicago Technical COVID-19 Response Team is comprised of faculty, staff, and students from all across campus (PSD, PME, MRSEC, BSD, UCMC, Arts, ANL, Polsky, Booth) working together to solve urgent technical engineering problems to improve COVID-19 outcomes. We have scientific expertise, design and rapid fabrication capabilities, and connections to like-minded networks worldwide. If you need help or would like to propose a project, please contact us.
We adapted a 3D printable design for hands-free door openers from Materialise to use #8-32 hardware and laser-cut silicone rubber grip strips. Tests with 3D printed prototypes led to cast aluminum parts with the help of Leitelt Bros. Foundry. About 100 are currently installed in the University of Chicago Medical Center.
We created two designs for N95 mask alternatives:
- Anesthesia mask with 3D printed adapter for HEPA filter or viral/bacterial filter (FDA approved components). Based on an idea by Boston Children's Hospital
- 3M 6200 facemask with 3D-printable HEPA filter adapter

Mask designs are provided for informational purposes only. Performance of designs have not been validated and may not be comparable to standard certified N95 masks. Designs are provided 'as-is' with no endorsements and no explict or implied warranties. End users assume all risks and responsibilities associated with use.
These are not final solutions, nor have these adapters been approved for medical use. All regulatory guidelines should be followed related to PPE use, and employers are required under OSHA to provide appropriate PPE for their workers. The devices described herein fall under guidance from the US FDA (FDA-2020-D-1138) “Enforcement Policy for Face Masks and Respirators During the Coronavirus Disease (COVID-19) Public Health Emergency” that is specific to the current COVID-19 pandemic: https://www.regulations.gov/docket?D=FDA-2020-D-1138.

We consulted on the design and fabrication of protective boxes for use during patient intubation procedures created for UCMC by Hero Solutions - Shield Project.
Evaluation and recommendations for open-source faceshield designs created for UCMC by mHub and others.
We are evaluating dual and quad ventilator mutliplexers at the University of Chicago Medical Center. Parts were 3D printed from designs by Colorado Makers Unite.
We evaluated options for creating custom NP swabs in-house and 3D printed NP swabs from several sources.
We are currently monitoring the Covid19-NP Swab manufacturing project.
The CDC now recommends that the general public wear homemade cloth masks to help fight the spread of COVID-19.
CDC recommended for all public settings.
DIY masks preferable to reserve medical masks for healthcare workers.
Cloth face coverings should be snug, secure, and not hamper breathing.
Below we link to designs that you may want to use, including no-sew masks. You can also find homemade masks on websites like Etsy.
Wearing simple cloth masks can prevent people who are infected – even if they are asymptomatic – from sending infectious droplets out into the air. They also provide limited protection to the wearer against larger droplets in the air. By wearing a cloth mask, you are protecting everyone around you, and also protecting yourself.
We are asking everyone to wear homemade or alternative cloth masks because it is critically important that medical / surgical masks remain available for healthcare workers.
Several designs for both sew and no-sew facemasks are available from the CDC.
#GetUsPPE has many design options as well.
We are here to help solve urgent problems. Please send requests for technical help, expertise, and project proposals to: firstname.lastname@example.org and we will let you know how we can help.
