Besides, its mass production forces to have a farm of printers. An extrusion is proposed to generate section constant swabs, trying to fulfill all requirements of **collection sufficiency** and **flexibiity requirements**. + +## Geometry proposal + +Based on the shapes that plastic swabs have, I want to try the strategy of generate thin walls of plastic instead of replicate hairs. Those thin walls could have more capacity of holds liquids samples as well as more area to viruses get attached to them. As they are so thin, they will be soft enough to flex as needed. + + + +The section to extrude is composed by a central circular section, in this case of 2.3mm that provides the stiffness needed.

Not every approval plastic has the same range and looking for which material is accepted to be inserted in mouth and nose has been a rabbit hole. The most successful output Ive got here has been research which material uses a conventional medical use NP swab.
