February 1 Meeting Preview

We will try to invite one of our possible guest speakers: Peter (manager of the demolition crew and civil engineer) or Tim (materials engineer).

If the guest speaker cannot make it to our meeting, we will be in the computer lab upstairs (room 19-124) learning how to use SolidWorks.  Please come to the engineering study room first (room 19-042), then we will go to the lab as a group.

Janurary 25 Meeting Summary

Congratulations to our club officers!  Our final club officers are shown below:

                              Co-Presidents: Chris, Justin
                              Co-vise Presidents: Jason, Jonathan
                              Co-Secretaries: Nicholas, Zita
                              Co-ICC Representatives: Daniel, Ivonne

In addition, our president Justin gave us a brief lecture on how a 3D printer works (see diagram below).



1) SolidWorks/Inventor

You draw out your design or mold of an object in either SolidWorks, which is available on the computers in the computer lab (room 19-124), or Inventor, which is available for download as a student version (http://students.autodesk.com/).  Justin recommends you use Inventor because he is more familiar with that software and thus can answer your questions more effectively; but, SolidWorks is fine as well.  When you are done with your design, please save it as a .stl file.

2) ReplicatorG

You import your .stl file to ReplicatorG, a software that allows you to set the origin, scale, definition, and the orientation of your object.  ReplicatorG then exports the information to G-code, a machine language that tells the print nozzle of the printer where to go in a coordinate system.

3) 3D Printer

Lastly, the 3D printer prints out your object, according to the G-code given, by placing consecutive layers of plastic.

We are thinking of doing the following projects with the 3D printer:
- design a case for Arduino
- make club rings
- create rubber band propelled boats
- build towers that can support a weight on top
- enter a design competition on instructables (http://www.instructables.com/contest/up2013/?show=ENTER) We can win a 3D printer!
