Week 8

We received our 3D print this week, it was smaller than predicted but all the pieces came out fine. We have the square base (figure 1), The beginning of the triangle walls withe the middle(figure 2) and the top of the tower(figure 3). there is also a picture of the fully assembled 3D model shown in figure 4.

Week 6

This week was dedicated towards working on our final report draft. Being that this is a mainly research based project we had a lot of transcribing of data as well as resources to site. However we did not have as many deliverables as other groups may have had. We are instead working on a powerpoint to display our research as well as a model which was created using the 3D printer. We had some difficulties coming up with a budget because the project is so research based and the 3D print model is free. So we decided for now to include binding materials for our model such as glue. For the actual final report we will be estimating the cost of the 3D print by finding the volume of the model we created and applying the cost per cubic inch

For the final report, we decided to split the workload into five sections. Steve worked on the “Problem Overview” and the “Existing Solution” section. Liam did the “Abstract” and the “Project Objective” sections. Chen worked on the “Project Timeline” and “Budget” sections. Tilvander worked on the “Final Model” section and organized the resources. Kyle did the “Research” and “Discussion” section.  

Week 7

This week was used to finish the design for the 3D print model in solidworks. The final hurdles to make it over was hollowing out the inside and enlarge the model. The hollowing out was trial and error to see how the cost could be reduced for our print. In order to enlarge the model we ended up printing three different pieces that would be put together when the print was done.

The assembly of the freedom tower is shown above. The assembly consisted of simple mates on the bottom of each piece. The finals dimensions are as follows: 1.5in by 1.5in base, 1in by 1in top face and a total height of 11in. The model is hollowed out to save on the cost of building materials.

Project Overview

The basis of the project is to compare the old world trade center to the newly constructed freedom tower. The task is to research the failings of the first world trade in the 9/11 attacks and see how the design was improved in the freedom tower. Also the design team is going to theoretically improve on the design of the freedom tower to see if further improvements can be made, such as anti natural disaster measures and an anti sway design.
