Assignment 4 Submission

 For this project we had to create an object that consists of multiple parts by either using the 3D printing technique or the laser cutting technique. I decided that I would use the 3D printing technique and began creating my object using GrassHopper.

The body:

I wanted to create a simple car object which I broke into 3 main parts, the body, axles and wheels which I will 3D print separately and then join together to create a simple car that is fully functional. I used a series of boxes and Boolean union commands to create the first part of the body. I then created a copy of the first body section and began creating cross members in between both sections. I then used the Boolean union command to join all sections of the body together to create one object.

The Axles:

The axles were rather easy to create as I used a simple cylinder that was long enough to connect both sections of the car together but also extend further to allow for the wheels. I made copies of each axle and used the Boolean difference command to create the axle opening between the body of the car and the axles.

The wheels:

The wheels were also created using a cylinder and a Boolean difference command was used to create an opening between the wheel and the axle which I will glue together once I print these parts.

The above screenshot conveys my final script that I developed using GrassHopper to create my simple car.

The above screenshot conveys my baked simple car in Rhino ready to be exported as .stl files for 3D printing.

This particular project has enabled me to think about the design process involved in creating such object. Before I began creating my object I had to analyse the design process and establish how the various components that formed my object were going to connect together.

After establishing the process that I would need to undertake and combined my knowledge of GrassHopper I was able to create my simple car. Throughout this semester I have been able to expand my knowledge on this new technology and I'm also beginning to understand what needs to be considered in order to ensure that the model will work in the real world once produced.
