optimization of process parameter is one of the ideal goals in laser sintering. the results of this process were measured as output parameters like: density, micro hardening, macro hardening, tension, roughness, stiffness, balling. in this paper, the influence of input parameter such as laser power, scan speed, material powder and etc are surveyed on output parameter like balling affection and ...

today radiology and imaging are the only and main method to generate geometrical data from body. 3d model of the body will give us the best and reliable information for better understanding and diagnostic. on the other hand with development of cad/cam and rapid prototyping, the 3d printers were born to build 3d models without considering the geometry. today the 3d printers are able to makes a 3...

normal 0 false false false en-us x-none ar-sa stereolithography process limits wider applications due to low dimensional accuracy comparing with cnc. to improve accuracy and reduce part distortion, understanding the physics involved in the relationship between the setup input parameters and the part dimensional accuracy is prerequisite. in this paper, a model is proposed to find and optimize im...

Rapid software prototyping is an iterative software development methodology aimed at improving the analysis, design, and development of proposed systems. This paper describes rapid prototyping at the system and 'software levels and reviews the characteristics of computeraided prototyping. We then describe the state-of-the-art in rapid prototyping and discuss technologies that improve the future...

Researchers have provided a number of different definitions, process models and classificatory schemes for both prototypes and prototyping approaches over the past two decades. Because there tends to be some confusion in the use of prototyping terms, in this review we attempt to place prototyping in context and delineate evolutionary prototyping approaches from other kinds development approache...
