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...
متن کاملEfficient concurrent toolpath planning for multi-material layered manufacturing
S.H. Choi and W.K. Zhu Department of Industrial and Manufacturing Systems Engineering, The University of Hong Kong, Hong Kong Abstract Reviewed, accepted September 10, 2008 This paper proposes an algorithm for planning efficient concurrent toolpaths to reduce the build-time of fabricating multi-material prototypes by layered manufacturing. The algorithm first sorts and partitions slice contours...
متن کاملAnti-aliasing for fused filament deposition
Layered manufacturing inherently suffers from staircase defects along surfaces that are gently slopped with respect to the build direction. Reducing the slice thickness improves the situation but never resolves it completely as flat layers remain a poor approximation of the true surface in these regions. In addition, reducing the slice thickness largely increases the print time. In this work we...

متن کاملIndependent Evaluation of Medical-Grade Bioresorbable Filaments for Fused Deposition Modelling/Fused Filament Fabrication of Tissue Engineered Constructs
Three-dimensional printing/additive manufacturing (3DP/AM) for tissue engineering and regenerative medicine (TE/RM) applications is a multifaceted research area encompassing biology, material science, engineering, and the clinical sciences. Although being quite mature as a research area, only a handful of clinical cases have been reported and even fewer commercial products have made it to the m...
