Process-Induced Fiber Orientation in Fused Filament Fabrication

Colored fused filament fabrication

Fig. 1. Our technique enables color printing with precisely controlled gradients using a filament printer. Le : The printer is equipped with an o -the-shelf nozzle that inputs multiple filaments (three in the picture) and outputs molten mixed plastic through a single exit hole. Such devices cannot directly be used to print gradients: the transition between mixtures takes time, and this timing v...

Solid Freeform Fabrication of Transparent Fused Quartz Using a Filament Fed Process

Glass is a critical material for many scientific and engineering applications including optics, communications, electronics, and hermetic seals. Despite this technological relevance, there has been minimal research toward Additive Manufacturing (AM) of glass, particularly optically transparent glass. Additive Manufacturing of transparent glass offers potential advantages for lower processing co...

Simple and Versatile 3D Printed Microfluidics Using Fused Filament Fabrication.

The uptake of microfluidics by the wider scientific community has been limited by the fabrication barrier created by the skills and equipment required for the production of traditional microfluidic devices. Here we present simple 3D printed microfluidic devices using an inexpensive and readily accessible printer with commercially available printer materials. We demonstrate that previously repor...

Fused Fiber Couplers: Basic Theory and Automated Fabrication

Review of Fabrication Techniques for Fused Fiber Components for Fiber Lasers

Fused fiber components are the key building blocks that enable reliable and efficient operation of high power fiber lasers. In this paper, we review fabrication techniques for the manufacture of such devices, including mode-field adaptors, fiber tapers, fused couplers, and fused combiners. We present the basic equations governing both the optical performance and fabrication requirements for the...
