Slicing algorithm for rapid prototyping data processing

Aiming at the accuracy and efficiency in rapid prototyping parts,the slicing methods and slicing profile precision were analyzed.Using the STL initial file which was widely adopted by rapid prototyping manufacturing systems,a data processing algorithm utilizing extended approximation to reconstruct slicing profile and progressive thinning slicing was proposed.An accurate slicing profile was obtained,step effect error was effectively reduced and slicing efficiency was improved.In comparison to current adopted direct slicing and adaptive slicing algorithm,this algorithm had higher prototyping accuracy and efficiency.Simulation results and practical processing proved its validity,practicality and system adaptability.
