3D PRINTING

-
I choose the hinge as my 3D printing project because it could not be easily made substratively due to the exist of joint and complex design if using laser cutting.
At first,I sketch the rectangle and a few circle .

Then I extrude the sketch  and then extrude the circle so can make it as a joint.

I construct the blue surface in the figure and make it as the mirror plane later.I use the mirror function so it will become the situation in the figure below.


After that,I create new component from bodies and  set the midplane,I use again the mirror function so the both side will be same design.
Then I copy the model so the two model will exist and I use the joint function to make them joint together. 
I fillet the corner of the model as 4.5 mm

After work is done, I save the file and export it as STL format. I open the Cura software and import the file which in STL format.

I change the setting which is the speed to 60mm/s and build plate adhesion in brim type the click the slice button so it will sow how long the time I need for 3D printing.
For 3D printer,  I preheat for the machine until 200°C  and go to search my file then open it for 3D printing then wait until the work is done. In the process,I have to see the 3D printer carefully so it would not exist any mistakes.

The figures below is my hero shot.



REFLECTION


3D printing is a skill that bring some convenient  to us. For example, we can use this skill when the laser cut skill cannot used to design the model due to a few technical problem. This 3D printing skill also reduce the fee because we can design a small model first and improve it before we make the original dimension model.
In this practical, it is interesting when I am doing the designation. Since I face once failure due to no combine the joint at all  so it motivates me to redo and improve any weakness part. This 3D printing skill is useful for the project in CP5070 because the small model can be created for our project so the project can be tested and be improved so we can minimise the fee.
I used to think that 3D printing skill is just same to laser cutting skill and it is more complex than laser cutting because the model should be designed in three dimension. Now I think that the 3D print is very useful because it provides the integrated structure although in small size. So next I will use this skill for my project as some body or part in the system so I can save the fee spent.

Aurdino Programming

I programme the arduino board by using Arduino IDE app which installed in the laptop.After I connect the USB Micro Port B with arduino board and mt laptop,then I open the Arduino IDE app and go to    File > Examples > Servo > Sweep. Then I adjust the value for pos value in the void loop part, one is used to  control the servo from  0 o  to 180 o  and the other is used to control the servo from   180 o  to 0 o    .Besides I also adjust the value for delay part  .As I finish adjusting these value so I can get the speed of servo motor moving desired. The code below is the source codes I used  #include <Servo.h> Servo myservo;  // create servo object to control a servo // twelve servo objects can be created on most boards int pos = 0;    // variable to store the servo position   void setup() {   myservo.attach(9);  // attaches the servo on pin 9 to the servo object } void ...

Person E (peijie) 2.FULL FACTORIAL DATA TABLE 3.FRACTIONAL FACTORIAL DATA TABLE SCOPE OF THE TEST The human factor is assumed to be negligible. Therefore different user will not have any effect on the flying distance of projectile. Flying distance for catapult A and catapult B is collected using the factors below: Arm length =  __ 28 __cm Start angle = ___ 20 __ degree Stop angle = ___ 60 __ degree Step 1: State the statistical Hypotheses: State the null hypothesis (H 0 ): The catapult that has 20cm arm length and start with angle 20 degree  and stop with 60 degree, the flying distance for both catapult A and B have no difference.   State the alternative hypothesis (H 1 ): The catapult that has 20cm arm length and start with angle 20 degree  and stop with 60 degree, the flying distance for both catapult A and B are different. Step 2: Formulate an analysis ...

DESIGN OF EXPERIMENT

FULL  FACTORIAL DESIGN Stop angle has the largest impact on the distance traveled by the projectile while arm length and start angle are relatively similar in terms of significance. FRACTIONAL  FACTORIAL DESIGN The results are similar to the full factorial design as the most significant factor is the stop angle followed by arm length and start angle. CONCLUSION I would recommend the full factorial. As by having only 16 data points, we already have cut down the number of runs to 2 each. So the data is already not as reliable. If we did fractional factorial, it might not give enough data for us to get accurate analysis and the right interactions. Furthermore, doing a full factorial for 16 data points is not considerably difficult, hence there should be no issues with doing the full factorial.
