covid-19-respirators's Introduction

Jet Propulsion Laboratory, California Institute of Technology (NASA JPL)

JPL Designed 3D Printable COVID-19-Respirators

figs/overview-respirator.png JPL designed and tested 3D printed respirators to help with the COVID-19 pandemic response. The designs and instructions for three different types of respirators and the resulting detailed test data is published here. In addition, designs and instructions for custom filters are also included. These designs were tested according to many criteria, including fit checks, breathability, comfort, etc, and the test results are available. Note that these respirators are not certified by NIOSH or any medical institution, so use at your own risk.

These designs, instructions, STL files, and JPL's initial test data are released to Open Source with the hope that companies and individuals who have access to 3D printers, and who want to help, can print or create these for those who need them. ​We are purposefully not using materials in the normal medical supply chain as it should be kept free to create commercial and certified respirators. We expect and hope that these designs will be commented on and improved by everyone during and after this pandemic.

To decide which respirator is right for your use, please consider these questions:

  1. How are you planning to use the mask?
  2. What tradeoffs between comfort and sealing are right for you? (See the test results)
  3. What materials do you have available?
  4. Which printers do you have access to?
  5. What’s your face shape?
  6. What’s your face size?

Below are sections for three different respirator designs that are intended for different uses, how to make your own cartridges and filters, how to test them, a disclaimer, and acknowledgements.

covid-19-respirators's Issues

Stringing and jamming with Cheetah TPU configuration file

The default Cheetah-TPU.ini configuration file results in stringing and jamming when loaded for the Prusa Mk3s w/ Cheetah TPU.

I was able to get clean and consistent results after applying the following changes:

  1. Disabled retraction
  2. Slowed all speed variables to 20mm/s
  3. Increased the extruder temp to 240C

To those unfamiliar with flex material (like I was before trying to print this), I recommend applying a glue stick to the work area prior to printing. Otherwise removing the print will likely result in warping or tearing.

Here's a photo of the comfort print after making the changes mentioned above.

Scale issue in the performance respirator wiki

I believe that the meton-sellion length in the performance mask wiki picture (mask size selection) has a scale issue. I believe it should either be divided by a 10 scale factor, or set in mm (~102-125cm seems really big for a face portion).

A call for community feedback!

If you have any comments or have tried one of these builds please let us know your feedback.
We are especially looking sizing and fit comments, or build issues.

Thank you!

Got an idea? Let us know...

Different applications can lead to different requirements. We have started to collect feedback from our local users and would like to hear from anyone that can have an idea or issue that we may be able to help with. Wearing a respirator might just become part of the norm for now so let's get creative and make the best of things.

Examples;
Styling
Voice Module
Active mood emojis
Respirator status monitoring
Accessories

Hope to hear from you!!

Cleaning Document

I know the 4 designs are all a bit different, but not all of them discuss cleaning the mask. I'd like to see a document on that topic. (my mother-in-laws nursing home is asking me about cleaning these, as we try to determine if they will meet their needs).
