Simulation of Pre processing for 3D printing
                    1. The motive behind _____ a 3D model is to transform the model into guidelines for the 3D printer
                  
                  
                  
                    2. By which preprocessing, we can print the object vertically upward, vertically downward and in horizontal plane.
                  
                  
                  
                    3. _________ helps in to improve the printed surface quality, shape accuracy and infill distribution quality
                  
                  
                  
                    4. First step in pre-processing is
                  
                  
                  
                    5. _____________ are required where the objects are unable to get printed directly
