# Swabs Rapid Prototyping
## Swabs Extruder
- Project Link:
## Hair STL Ecporter
- Demo Link:
- A tool to export STL (and later SLC) files to test the vaiability of using CBA's Stratasys Object260 Connex3 printer for printing hair like structures.

- Tom Lutz progress here
## FDM Approaches
- Jack Forman have been leading the effort to see how we can use FDM printers to print har like structures.
- The first suggestions is to follow an approach similar to the "furbrication" project:

- Another idea Jack just tested is to use his 3-D Printed textiles approach to 3D print pseudo-foams (basically under extruding volumes instead of sheets).
- This is a photo of the first attempt with PLA. There are some quick optimization that can be made to this (extrude even less to make more porous, print inside out, etc.); however, the ultimate issue is the PLA is too crunchy/brittle, there is a possibility it migh break off in someone nose.
- Jack will be moving next onto **TPU**, which he had luck printing super tough flexible textiles with [in the past]( (since that video he has gotten the pattern to be more homogenous). The biocompatibility is not as good as PLA, but we do not know how much of an issue that is since its a quick swab.
## Jifei's STL
- [Formlabs response](
![Formlabs Swabs](img/formlabs-tests.png)
- Jifei said their STL design has been tested at Beth Israel, and Formlabs is getting ready to scale that. We could add our Form printers to that fleet, I'll ping Max.
## Foams
- In Neikl's review of fab lab projects, there was a note that foams work well for swab sample collection. There might be a quick approach to stamp out foam cylinders.
