Week 12

 This week, we were taught on the use and the importance of the 3D printer. Firstly we learnt about what is 3D printing and some examples that 3D printing was beneficial. 

Digital fabrication is a production process that combines 3D modeling or computing-aided design (CAD) with additive and subtractive manufacturing. Subtractive manufacturing is when a material is cut into its desired shape/form while additive manufacturing builds the desired item from bottom to top. This is known as 3D printing. Nowadays, more people opt to use additive manufacturing than subtractive manufacturing due to advantages that additive manufacturing brings. 

Additive Manufacturing                                                            Subtractive Manufacturing

- More cost and material efficient                                         -    Uses up more materials and money

- Faster                                                                                   - Slower 

With the use of 3D printer, prototyping is now much easier and efficient as performing test and physical evaluation is now faster to do. Replacing different parts of older equipments are also possible by changing the type of material use for 3D printing. One example was replacing aluminum or steel with NYLON 12 carbon fiber. It will be much stronger, cost efficient and faster to make than those counterparts. 

We were now than tasked  to develop teaching materials for a designated topic and present it to the class. For our group, our topic was the slicer settings for quality printout. Here is our slides.

 Hello peeps. This week we carried out an experiment we were assigned called the air-lift pump challenge. we were required to contract the set up with provided equipment.  Here is our equipment and experimental setup  Here are the results we obtained from the experiment Experiment 1 b = 10cm, Y=16.5cm a (cm) X (cm) Flowrate (ml/s) Average Flowrate (ml/s) Run 1 Run 2 Run 3 2 14.5 5.93 5.80 5.71 5.81 4 12.5 4.20 4.13 4.23 4.19 6 10.5 2.82 2.63 2.60 2.68 8 8.5 1.39 1.11 1.93 1.47 10 6.5 0.39 0.37 0.39 0.49 Experiment 2 a = 2cm, X=14.5 b (cm) Y (cm) Flowrate (ml/s) Average Flowrate (ml/s) Run 1 Run 2 Run 3 10* 16.5 5.93 5.80 5.71 5.81 12 14.5 2.89 3.78 3.20 3.29 14 12.5 1.35 1.35 1.20 1.3 16 10.5 0.19 0.19 0.18 0.19 18 8.5 0 0 0 0 20 6.5 0 0 0 0 we used an estimated flowrate of 0 as t water was barely being pumped out. it took too long to collect 100ml of water and it was not feasible for the experimenter to hold the tube for so long. 1.       ...

Week 4 Activity

  Roy, Nigel ,Bjorn, Vernon Group 3 DCHE2A02 Topic: Material Selection for Inner Layer of Thermoflask For week 4, we went to revisit our last year module which was the materials for design and we were tasked to find the right material for the inner layer of a thermoflask. In materials for design, we needed to find the right requirements for the material and from there find different suitable materials. We then use the COWS matrix (Criteria, Options, Weightage and Score) to determine the best material. Here is our findings. Material Requirements In order for the liquid inside the thermoflask to remain hot/cold, the inner layer of the thermoflask must reduce the amount of heat transfer from the liquid to the surrounding. The inner layer thus should have a low thermal conductivity and a high melting point.   Since the inner layer will be in contact with water, it must resist corrosion by any liquid put into it, water and acids from soda drinks. It will be used for drinking, so i...

Week 1 Group Retreat Activity

 Firstly, we went to buy drinks as we were feeling very thirsty and while drinking we were chatting about the stuff we did during the holidays.  After finishing our drinks, we had to use the toilet. We also decided to prank Vernon by taking a wefie with him using the toilet. We were feeling stressed due to the long and hectic day and decided that we needed to distress by playing some mobile games together. We were feeling restless, so we decided to do some pushups together. Despite it being tiring, all of us had plenty of fun together. All in all, this was a fun bonding experience for our group and we felt that this opportunity allowed us to get to know one another better.
