Novel 2D Dynamic Elasticity Maps for Inspection of Anisotropic Properties in Fused Deposition Modeling Objects

Curved Layer Fused Deposition Modeling

Current Fused Deposition Modeling (FDM) technologies deposit material as flat layers. The result is a “stair-case” effect on non-vertical or horizontal surfaces, and compromised part strength because of weakness between the laminations. This paper describes a FDM method through which layers of build material are deposited as curved layers following the shape of the part, thus removing the stair...

Anisotropic thermo-elasticity in 2D. Part I: A unified treatment

In this note we develop tools and techniques for the treatment of anisotropic thermo-elasticity in two space dimensions. We use a diagonalisation technique to obtain properties of the characteristic roots of the full symbol of the system in order to prove L–L decay rates for its solutions.

Anisotropic thermo-elasticity in 2D. Part II: Applications

This note deals with concrete applications of the general treatment of anisotropic thermo-elasticity developed in the first part [M. Reissig, J. Wirth, Anisotropic thermo-elasticity in 2D A unified treatment, Asympt. Anal. ?? (????) ??–??]. We give dispersive decay rates for solutions to the type-1 system of thermo-elasticity for certain types of anisotropic media. 1. Elastic operators and ther...

Dual-color mixing for fused deposition modeling printers

In this work we detail a method that leverages the two color heads of recent low-end fused deposition modeling (FDM) 3D printers to produce continuous tone imagery. The challenge behind producing such two-tone imagery is how to finely interleave the two colors while minimizing the switching between print heads, making each color printed span as long and continuous as possible to avoid artifacts...
