CADD 2100 TERM PROJECT PART 2 By: Lazar Savic MECHANICAL APPPLICATIONS OF 3D PRINTING

INTRODUCTION  This is the problem I have encounter while mountain biking.  Nylon-based plastics could not support the load of the crank shaft

THE INSPIRATION  The Applications in the images found online are what gave me inspiration.  The ability to make quick, accurate and incredibly precise repairs to any broken object.  Plastics make a great filler material for connections + they are very malleable before they cure.

THE PROCESS -01 Finding the Right Medium  The answer to this problem was obviously to redesign the object and make it again out of plastic  But what plastic was good enough for what I needed?  What type of plastics do 3D printers use?

THE PROCESS -01 Finding the Right Medium  Assessing the key material for the project was essential  I developed a chart to explore the practicality of each type of plastic  ABS was the best choice because it was most abundent in the classroom

THE PROCESS -02 Dimensional Analysis  The dimensions of the part were found by using a caliper to accurately measure all the sizes  Tolerances and clearances were very important for doing this  This application is called reverse engineering.

THE PROCESS -03 3D Designing  The purpose of analyzing the object was to put the dimensions of the object in CAD software  For parasolids format. Easier to print  Solidworks seemed like the ideal software for such a thing

THE PROCESS -03 2D Designing

THE PROCESS -04 Kinematic & Dynamic Analysis  Rapid analysis and prototyping was something that had to be done  When doing physics analysis knowledge of materials is important.  Software has proved the model and the changes I made to it to be successful

THE PROCESS -04 Kinematic & Dynamic Analysis

THE PROCESS -05 3D Print Process  The file is then converted to.STL format where it can be evaluated  The software used is Catalyst FX  67 cubic cm were used to print the object  The entire part was printed as a water tight parasolid at 100%

THE PROCESS -06 Fitting & Finishing

FINAL PRODUCT

CONCLUSION
