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...

Optimization under uncertainty of a composite fabrication process using a deterministic one-stage approach

Process design under uncertainty has received considerable attention in recent years, and has led to the development of several modeling and solution approaches. These approaches are broadly categorized under stochastic formulations (model parameters with probability distributions), multiperiod formulations (where uncertain parameters are discretized into a number of deterministic realizations)...

Chance constrained programming approach to process optimization under uncertainty

Deterministic optimization approaches have been well developed and widely used in the process industry to accomplish off-line and on-line process optimization. The challenging task for the academic research currently is to address large-scale, complex optimization problems under various uncertainties. Therefore, investigations on the development of stochastic optimization approaches are necessi...
