Adaptive Slicing for SLS Prototyping

NURBS-based adaptive slicing for efficient rapid prototyping

This paper presents slicing algorithms for efficient model prototyping. The algorithms directly operate upon a non-uniform rational B-spline surface model. An adaptive slicing algorithm is developed to obtain an accurate and smooth part surface. A selective hatching strategy is employed to further reduce the build time by solidifying the kernel regions of a part with the maximum allowable thick...

Direct Slicing of a Point Set Model for Rapid Prototyping

Recently point set model is getting increasing research attention in many geometric modeling application areas including computer graphics and CAD/CAM. This paper presents a novel approach to directly slicing point set model with the focus on making rapid prototyping part out of point set model without making any mesh or surface. Main challenge in handling point set model lies in how to interpr...

SLS-FEMTO: Beam halo formation and maximum repetition rate for laser slicing

Slicing Algorithm of VRML Model in Rapid Prototyping

VRML (Virtual Reality Modeling Language) as an international standard for Virtual Reality, has already been widely adopted for graphical representation of 3D objects over the Web. Adopting VRML model in RP (Rapid Prototyping) can reduce the precision loss which is caused by triangulation in generating STL file. Hence exploring a slicing method and software for VRML model is significant to impro...

Hardware Accelerated Terrain Rendering by Adaptive Slicing

Many terrain rendering algorithms have been developed, which perform a variety of mesh optimizations to achieve interactive frame rates. The most prominent approach is the so called continuous level of detail technique, which approximates a terrain by computing a view-dependent triangulation. One disadvantage of this approach is the fact that the rendered terrain is of course just an approximat...
