Stereolithography Creating a 3D model Using the liquid photocurable polymer--- can solidify when stuck (touched) by laser beam Producing complex prototypes of castings and other objects in hours, instead of days and weeks in traditional ways
The sterolithography process Create 3D CAD model (with a support structure) Slice the model into cross sections of 0.12mm 2.Orient and support to 0.5mm in thickness 1.CAD design 3.CAD interface Download the above CAD data into the sterolithography machine The part(model)is 10.Final cure 4.Slice created from the bottom 5.Interface up,on the platform just 9.Build 6.Merge 7.Utility below the surface of the 8.Prepare liquid photocurable polymer in a vat
The sterolithography process Create 3D CAD model (with a support structure) Slice the model into cross sections of 0.12mm to 0.5mm in thickness Download the above CAD data into the sterolithography machine The part (model) is created from the bottom up, on the platform just below the surface of the liquid photocurable polymer in a vat
The machine's control unit guides a X-Y movement Z movement fine laser beam onto the surface of the UV light source elevator liquid plastic The liquid plastic solidifies wherever Laser beam Liquid it is struck by the laser beam surface After each slice is formed,the Formed platform drops a programmed distance object The above sequence is repeated until the entire model is formed The finished part requires final ultraviolet curing (processing) removed from the platform and the support structure is taken away >The part's surface can then be finished by filing,sanding,and polishing as desired
