Slicing 3D CAD Model in STL Format and Laser Path Generation

Munir Eragubi

Abstract— The program in this paper is an essential component of the Rapid Prototyping Machine Manufacturing Project. The process of Rapid Prototyping is an integrated product manufacturing process without human interference. Product data which has been designed by CAD software is inserted into the program, then send directly to the Rapid Prototyping Machine, which manufactures the final product by converting a slice of the raw material powder to solid material, then bond it to the previous layer automatically. The program reads the data of 3D design, which has been saved in STL format file, this requires a decoder for the codes used to store these type of files, the program then displays the design graphically to insure the form and dimensions of the model, then the process of slicing of this model digitally starts from the bottom of the design and finishes at the highest point; the outer contour line of the slice defines the material of the model, the inner contours defines the cavities within the model, a tool path for the laser beam is generated to covers all the areas that represent the material area, this Tool Path is used to generate instruction codes sent to the laser source which controls the direction of the Laser beam, which converts the raw material powder to a solid final product.

Index Terms— STL file format, rapid prototyping, slicing 3D model, laser path.
