Week 2 (Tutorial) For the lesson in Week 2, we were given an introduction to the various types of laser cutter machines available in the market. Background Information A laser cutter refers to a machine that uses motors that are controlled by a computer to cut and engrave material using a laser beam. Since the type of laser cutter machine used in the FabLab is the carbon dioxide (CO 2 ) laser cutter machine, we will be focusing our scope on the CO 2  laser cutter machine. Working Principles The CO 2  laser cutter machine contains a mechanism called the CO 2  laser tube, which produces the CO 2  laser. It is a glass tube with carbon dioxide gas and some nitrogen gas sealed in it. Figure 1: CO 2  laser tube (HPC Laser, no date) High voltage electricity is passed through the tube, which excites the gas particles and produces a laser beam. One end of the tube contains a partially-reflective mirror, while the other end holds a fully-reflective mirror. The light is reflected back and forth

Week 1 (Tutorial + Activity) For our first activity in Week 1, we were asked to create a keyring with our name on it as a refresher on how to use Fusion 360. This refresher was greatly needed, as over the holidays, I had forgotten how to use Fusion 360. As Fusion 360 (and Computer-Aided Drawing and Drafting in general) is an important skill to master when it comes to this module, this refresher will prove to be very useful in upcoming assignments and reports. 1. Create a new sketch and select a plane to work on. 2. Create a two-point rectangle to form the main body of the keyring. 3. Use the " Fillet " feature to round off the corners of the keyring. Figure 1: Step 3 (Filleting process) 4. Use the " Extrusion " tool to make the object 3D. 5. Apply a " Centre Diameter Circle " for the ring to slot through. Figure 2: Step 5 (Keyring Hole) 6. Create another  extrusion  in the body of the keyring. Figure 3: Step 6 (Second Extrusion) 7. Create a " Text &
