EnvisionTEC Swabs

A shortage of the necessary diagnostic and treatment supplies has been discovered, and while many businesses have jumped in to help, it is 3D printing that may be able to provide real answers for how to combat the supply chain crisis.

Working hand-in-hand with healthcare leaders, EnvisionTEC has identified several areas where their specific strengths in biocompatible materials and fast, precise 3D printing equipment can help to provide replenishment of stocks as well as new, alternative solutions.

Nasopharyngeal (NP) Swabs

EnvisionTEC engineers have designed a collection tip for a flexible nasal swab.  Brian Nilson, of Nilson Laboratories, 3D printed the final design for testing.  He was able to print 400 of the swabs on his Envision One cDLM 3D printer in two hours.  The testing process is comprised of a ten stage mechanical testing, a two-part absorption test, a biological/chemical testing procedure to ensure the swab absorbs viral RNA particles and does not interfere with PCA/reagents, and a sample collection testing procedure.  To pass, a sample needed to use a material that is approved as chemically safe, would bend 180 degrees without breaking, and the design needed to be able to safely collect enough virus particles from the nasal passage to effectively test.

EnvisionTEC worked with Beth Israel Deaconess Medical Center (BIDMC) of Boston’s Biomedical Laboratory, to obtain IRB approval. To read the full manuscript concerning this study as published in the Journal of Clinical Biology,  Click Here
