3D Printed Lightguide Array for Optical Imaging
This technology is a collection of transparent glass or polymer elements (a lightguide array) for routing light to an array of sensors for use in spectral imaging.
Background:
Spectral imaging combines traditional optical images with spectroscopy, to capture the spectral properties at each part of an image. This technology is useful because it can...

Improved Fused Filament Deposition 3D Printing Using Filaments Coated With Thermoreversible Thermosets
This invention demonstrates a new polymer to coat the spool of thermoplastic filament used in fused deposition modeling (FDM) 3D printing with a thermoreversible thermoset. The goal is to provide a layer that will liquefy in the hot printer nozzle to produce a lower viscosity liquid polymer. This coats the melted filament and increases the wetting and...
