SLS 3D Printed Stopgap Face Mask Comes In Rescue


Challenges:

A shortage of PPE for protective face masks is creating a hazardous situation for frontline workers and secondary support service health care professionals. Face masks that are intended for a medical purpose in the United States are regulated by FDA (see guidance). When FDA-cleared masks or respirators are unavailable, healthcare professionals may choose to improvise PPE. Similar situations are likely to arise in jurisdictions not regulated by FDA.

Solutions:

3D Systems worked with engineers and clinicians at the Veterans Health Administration to develop an emergency Stopgap Face Mask (SFM). The SFM is available in multiple sizes and is printed from a biocompatible nylon material – Duraform PA or Duraform ProX PA, using Selective Laser Sintering technology. The SFM is comprised of the 3d printed mask and filter cover, two elastic strips, and a rectangular patch of filter material. The SFM can be reprocessed using disinfectants and/or autoclaved.

Benefits:

The Stopgap Face Mask is to be used for medical purposes when standard PPE is unavailable or for less critical non-medical environments that do not require compliant PPE. The SFM design has undergone review in a clinical setting and is recommended for use when manufactured according to the guidance and used as instructed in the IFU.
