The outer ear can be printed with a veriety of TPU materials
STL files are scaled and oriented for printing. Enable support only on outer edges.
The middle ear files can be printed with common PLA filament.
The outer ear file will need to be printed with a flexible filament.
Ninjaflex 85A ispreferred, with 2 walls and 10% infillhttps://ninjatek.com/ninjaflex/
Sainsmart TPU can be substituted for printers which cant handle ninjaflex, using 1 wall, no infillhttps://www.sainsmart.com/products/all-colors-tpu-flexible-filament-1-75mm-0-8kg-1-76lb
3D printable myringotomy trainer developed by David Bracken MD, Charles Coffey MD, and Scott McAvoy at the UCSD Library Digital Media Lab.
CT imagery was segmented and formated as a 3D volume, then further segmented in Blender to create three separate components, The outer ear is separated to be printed with flexible material, then adhered to the middle ear with CN glue. The middle ear is separated into two pieces at the eardrum, where a square of nitrile glove can be placed to simulate the tympanic membrane. The two halves are held together with reuseable zip ties
The 3D file can be previewed here:https://sketchfab.com/3d-models/myringotomy-trainer-0199301ff51e4da4b72f3deca1a39ff5
