3D Printing

-

Overview

During our end of term holiday, we were tasked to create an object which cannot be made subtractively. This means that  a model that cannot be easily made by trimming unnecessary parts from an original object. Objects that cannot be easily made subtractively are whistle, ball in a box and hinges etc. We then had to return to campus to 3D print out the designs.

Hence, the 3D object that I have made is a simple hinge. Below is my embed link of the hinge that I created which is able to turn 180 Degrees.



Steps

Now, here is a step by step guide to create this design :) 

Step 1: Create a Rectangle with 0.25cm Breath and 5cm Length



Step 2: Create a 2 point circle with diameter of 1 cm and center diameter circle with 0.4 cm 


Step 3: Extrude the base as follows


Step 4: Turn on visibility of sketch and extrude the circle as follow


Step 5: Select "Create" then "Rectangular Pattern"
and change right window "Faces" to "Features". 


Step 6: It should look something like this and you have to activate the main component


Step 7: Hide Component 1 followed by extruding base again and finally unhide component 1, results are as follows


Step 8: Extrude the cylinder as follow and join them all up


Step 9: Activate main component and it should look something like this


Step 10: Move component 1 away and ground it


Step 11: Select "Joint" and Click on the holes of the cylinder as indicated in the picture below


Step 12: Hit "Flip" on the right window to make it look like this 


Step 13: Right click on the joint and hit edit joint limits. Put in minimum 0 degree and max 180 degree

Reflection

In my opinion, I had a lot of fun for this activity. Initially, when I arrived at the venue, I was unsure of how to operate the machine. However, after learning what does each option on the 3D machine does, I am confident that I am able to operate the machine on my own. Through this activity, I get to know what a software called Cura Slicer is. It is essentially a software that converts the STL files and many other formats into layers. It can also determine the print characteristic of each layer and convert it into gcode. The gcode is then transferred to the 3D printing machine through a micro SD card. To my mind, I think that learning how to operate the 3D printing is a very good skill to have. In the future, I think that many objects and items even including human organs or food can be 3D printed. To sum, I had a very enjoyable learning experience under the guidance of TEs.

Arduino Programming Task Overview For this week, week 5's practical, I learned about what an Arduino is and what is Arduino programming. I also learned about the different parts of an Arduino board as well as different components that can be used with an Arduino board. This includes LEDs etc. We were tasked with 4 activities. They include:  a. Interface a Potentiometer Analog Input to maker UNO board and measure its signal in serial monitor Arduino IDE  b. Interface a LDR to maker UNO board and measure its signal in serial monitor Arduino IDE  c.  Interface 3 LEDs ( Red , Yellow , Green ) to maker UNO board and program it to perform something (fade or flash etc)  d.  Interface the DC motor to maker UNO board and program it to on and off using push button on the board Potentiometer Analog Input This is how it looks like on Tinkercad ! After the assembly of the setup, I proceeded with copying and pasting the code that was provided by Tinkercad. However, there...

Overview In today's CP5070 lesson, we were given a refresher course about Fusion360. So what is Fusion360? It is basically the one and only tool that connects the entire product development process into a single CAD/CAM/CAE cloud-based platform. It is able to work well on both Mac and Windows. What we had to do for today's lesson is re-creating a keychain using Fusion360 with our name on it. In my opinion, I find such programme fun and exciting to use and we can get to explore and create our very own products. After we are done with the products, we are able to send it to a 3D Printer to get it printed out using an assortment of different materials. To my mind, learning to use such programme and 3D Printing is a very crucial skill as I believe this field of technology would continue grow and play a very important parts of our daily lives. An example is in the future, I believe it is possible to even print out functioning human organs and this would greatly benefit those who tru...

Overview  Hello, welcome back to my blog ! For this week's blog entry, it is about Design Of Experiments (DOE). So what is DOE? DOE is essentially a statistics based approach to designing experiments. Documentation of case study  For Case Study 1, I was appointed as the CEO by my group and I was tasked to complete this case study together with my friend, Nikkisha who is the CFO. Part 1:   Determining effect on single factors and their ranking Recreating the table shown in the PDF, into an Excel file. It looks something like this Where, A = Diameter of bowl   B = Microwaving time C = Power However, for ease of convenience. I have replaced the + and - signs to their respective high and low values. Next, I used this template and filled in the Bullets into the "Average" Column. It is shown as follows This is the data that I got for filling the values in the above table With the data that I arrived at, I tabulated the graph and it looks something like this The ranking mos...
