Protecting Facets in Layered Manufacturing

Geometric Algorithms for Layered Manufacturing

This research project was funded by the German Academic Exchange Office (DAAD) and the National Science Foundation (NSF). Our project partner was Prof. Ravi Janardan (Department of Computer Science, University of Minnesota, Minneapolis). Initially, funding was given for the years 1998 and 1999. Then the project was extended to the year 2000. In this report, our original project description and ...

Tailoring Material Properties in Layered Manufacturing

This paper discusses an approach for tailoring material properties in parts fabricated using Layered Manufacturing (LM). Solid model of the part is subdivided into various sub regions based on stress analysis. All subdivided regions are fabricated together by using Rapid Prototyping with process parameter values assigned as per their stress values. As mechanical properties are varying with proc...

Thin-Wall Calculation for Layered Manufacturing

We describe a new algorithm for making partially hollow layered parts with thin, dense walls of approximately uniform thickness, for faster build times and reduced material usage. We have implemented our algorithm and tested its output on a fused deposition modeling (FDM) machine, using separate build volumes for a loosely filled interior and a thin, solid, exterior wall. The build volumes are ...

Layered Manufacturing: Current Status and Future Trends

This paper reviews the emerging field of layered manufacturing. This field is little over 10 years old but a significant amount of research has been conducted and results to date are quite promising. We consider three broad topics namely, design systems for heterogeneous objects, layered manufacturing processes, and process planning techniques. Several applications/examples are included in the ...
