Geometric algorithms for layered manufacturing

Deformation of the Structural Details of the Components Created by the Rapid Prototyping Method

“…For example, Figures 2a and 2b show two triangles of similar dimensions (4 and 6) but having different orientation towards relation to the increment layer of creating the model. Triangle (6), after the slicing process has collapsed, whereas triangle (4) has a slight deformation of the shape. Figures 2c and 2d Figure 3 presents deformation mechanisms for micro-inscriptions that have appeared on the elements made by the rapid prototyping method.…”

“…Although rapid prototyping devices work very precisely, huge differences often happen between a designed element and a manufactured model. Differences can determine the usefulness of the parts produced in rapid prototyping systems, which seems to be an essential problem [5,6]. This paper presents possible reasons for differences as well as suggests actions that can minimize unexpected effects.…”

“…Figures2c and 2dpresent a similar process in which the mesh of triangles is rotated by an angle of 90 o . Other triangles(4,6) collapsed in this position. It causes the deformation of produced components.…”
