Rapid Prototyping with Sloping Surfaces
نویسنده
چکیده
TruSurf is a new system for building solid objects from layers with sloping surfaces that closely match the designed surface shape. The advantages of using sloping surfaces over stepped edges are improved surface finish, and decreased build time through the use of thicker layers. TruSurf uses B-spline surfaces to describe the part, and calculate the sloped path of the layer cutting medium. The operation of the system is described in detail, and results from the production of some test parts are presented. Finally, some ways for improving accuracy are discussed, including using principal directions of minimum surface curvature, and using a curved cutting medium to produce layers.

Results of the study of surface roughness of the aircraft engine blade model, produced with various methods of rapid prototyping are presented. Blade models were made with two incremental methods of rapid prototyping: stereo lithography (SLA-250 device) and three-dimensional printing (Z510 Spectrum printer). In incremental methods of rapid prototyping a model is formed by hardening of consecuti...
متن کاملAdaptive Slicing with Sloping Layer Surfaces
An adaptive slicing procedure for improving the geometric accuracy of layered manufacturing techniques is presented. Unlike previous procedures, the present method uses layers with sloping boundary surfaces that closely match the shape of the required surface. This greatly reduces the stair case effect which is characteristic of layered components with square edges. Two measures of error are co...

Three tools for the rapid prototyping of micron and sub-micron scale devices are presented. These tools represent methods for the manufacture of PEMS, or Printed micro Electro Mechanical Systems, and are enabled because they exploit the novel properties of nanocrystalline materials and their interactions with energetic beams. UV contact mask lithography was used to directly pattern metallic nan...
