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
