EnvisionTEC Swab


EnvisionTEC engineers have designed a 3D printed collection tip for a flexible nasal swab that has completed testing in an IRB-approved clinical trial for use in this unprecedented time. In order to be given this approval, a rigorous, multi-phase testing procedure was required. This testing of both the design and the material included several rigorous mechanical and chemical tests. This was done to ensure that the swabs pick up viral RNA particles and do not interfere with PCR/reagents, that they are chemically safe, that they would bend 180 degrees without breaking, and that the design would be able to safely collect enough viral particles from the nasal passage to effectively test.

Formlabs Swabs


Nasopharyngeal (NP) swabs are flexible sticks with a bristled end that are inserted into the nose to the back of the nasal cavity and swept around to collect material that sticks to, or wicks up, the bristles. The swab is then placed into a vial that contains a culture, medium swab sticks have an intentionally weak point 7-8 cm from the bristled tip, which allows the stick to be broken to the correct length so that the vial can be capped before its is transported to a lab for testing.
