3D Printing

-

For our 3D Printing Session, our objective was to design an object that could not be made Subtractively.

After some failed brainstorming and searching online, I decided to follow this guide on Youtube, where he makes a cool looking pencil holder. This pencil holder cannot be made subtractively as cutting out the design along the curved surface of the pencil holder.

Step 1:

From the Top view, sketch a circle with a diameter of 70mm.


Step 2:

Extrude the circle by 90mm to form a cylinder.



Step 3: 
Use the shell function to hollow the cylinder while leaving a 4mm gap.






Step 4: 
Create a Slot sketch and adjust its position where it is going to go on the pencil holder.









Step 5: 
Use the Emboss tool to emboss the slot design onto the cylinder.






Step 6:
Use the Circular Pattern Function to repeat the slot design all around the cylinder 10 times.











Here's the Finished Design:







In Cura, the product in its original size would take well over our restricted time of an hour's 3D printing time, which required me to downscale it. After a bit of tweaking, I managed to reduce its printing time to 49 minutes. Here are the settings I used:



Here's how the printed product looks:

Reflection:

During this 3D printing practical, I got to utilize the 3D printing software Cura to design and 3D print an object that I designed, and also got to see the 3D printer in motion, printing out my object, which was overall a very interesting and unique experience for me. I had always been interested in 3D printing objects that I find on the internet, and with the introduction of the presence of 3D printing being a possibility in school, I hope that i would be able to find time to come to the lab and 3D print more objects in the future.

Arduino Programming For Arduino Programming, my class was tasked to accomplish 2 things. Firstly, each of us had to complete an individual competency test, and also write a code that would make the wings of a unicorn flap, and a bonus task of combining the flapping with something else.  To start off, my group used an "Sweep" example code provided by the Arduino Software, then tweaked it a little. We changed the Servo's initial position to from 0 to 10 degrees , changed the sweeping angles to go from 10 to 120 degrees and changed the degree increase rate to steps of 10 degrees . We also changed the delay when rotating anti-clockwise to 25ms, and  15ms when rotating clockwise. At first, we set it to have a slower flapping speed, but it was too slow by our lecturer's standards, so we increased it after. Finalized Code can be downloaded  here Prototype Design of our Unicorn We ran into 2 main problems during the Arduino Practical. Firstly,  when we attempted to do the

Our team's Chemical Device Our chemical device is a door handle sanitizer.  It aims to reduce the problem of high infection rates of Covid-19 through indirect contact by an infected person. This can be through everyday objects that have been contaminated such as the door handle. Its function is to detect the hand on the door handle and spray hand sanitizer onto the door handle after a person lets go of the door handle. By doing so, it kills any bacteria or viruses on the door handle which in turns reduces the risk and reduces the rate of Covid-19 infections through indirect contact.
