3D design week - day 4


Today was the last day in the 3D design week concerning practical work. The tasks today were to create a structure out of spaghetti sticks and also to later cost them with paper in ways so that we could do a strength test.

Reflecting:

Firstly looking at the first task of the day of creating a structure, we were asked for this structure to have the specification of holding 3 plastic balls without them falling or being in contact with the ground in any way. When I began this task I found it extremely difficult as I had never even thought about working with spaghetti sticks to create a structure. When prototyping I found it very difficult to use blue tac with these pieces as they kept slipping and sliding away from the blue tac, which did not seem to hold the sticks in place no matter how much pressure I applied to it. However at the end of the task I feel that I eventually got on quite well, as I successfully completed the structure withing my time limit. I was very happy with what I achieved. As it was firstly not a boring cuboid shape it a triangular one, which made it more appealing than a simple box structure . Also, it successfully fulfilled the deoxidiser ion that was required of us to nearly hold 3 plastic play balls on its structure without falling or toppling over, or breaking the structure in any way. When I asked my peers for feedback, the main piece of feedback that I received was that the triangular prism structure dos indeed make it look more interesting than if it would have been a cuboid one. Also I received positive feedback on the structure of the ball holders, which were all angled downwards so that the ball could not move from side to side, keeping it very secure from falling. From my tutor Geofd I was given feedback that I should have somehow incorporated playing cards into the structure as levels or walls, because it would help to represent me more, ideally mixing graphics along with 3D design together, which would have made it very eye catching. From the overall task the main thing I learnt was proper usage of a glue gun which I had never used before. I learned this through the construction process with help from a friend, who showed me the safety measures that should have been in place like placing cardboard on the table surface before glueing ect.this will affect my suture work in a way that if I am ever doing another 3D graphics project, I will use superglue to hold orbit as it provides a very strong bond between the spaghetti sticks, and this strong holding property could come in handy for many other future projects involving creating structures. 

Looking at the second part of the day, we were given the task of having a limited umm we of 4 A4 sheets and 4 A3 sheets of paper, to create a barrier or another internal structure within our spaghetti onesx that it could withstand the weight of a ball that would be dropped onto it. I got on with this task fairly well as well, seeing as it only involved cutting paper to a certain height and width, and then adhering it to my structure. I feel that I achieved my goals slightly as when tested, my structure did not fully break, but mainly went flying to the side of the ball after the impact. Upon looking inside of it I found that the rolled up tubes I placed inside were the cause of this survival of the main structure as they were thick enough to not crumple up when hit by the ball. I received positive feedback on my cylinder/rolled up tube comes that I placed inside the structure,, which also gave an India to a few others in my class to employ the same methods in trying to strengthen theirs. However the only negative pont was that my tubes did not stand up right completely, meaning that the strength distribution was not equal along the structure. From this task I learnt that to ensure maximum resistant strength is present in a structure, the supports inside cannot be dangling around or wobbly, as this will not add to the strength and in turn will have no effect on it.from this task I learnt that it would most likely be easier to create my structures within the framework of my structure first rather than after hthe paper walls were placed on. Because I did not do this I spent a large amount of time trying to adhere the cylinder tunes inside the structure without damadging it. 

Analysing:
I think that the most successful part of my work was how the structure managed to hold the 3 balls without toppling over, as I found that one side was raised higher than the other. However this had no effect and was only off balanced by a fration. I was happy with this as if the balance was more off, it could have possibly resulted in my structure falling, smashing, and me having to create it once again. In addition to this I found my way of coating it with paper slightly successful as it still held some strength when the package was dropped onto it.  Even though it had collapsed upon impact, closer look at the internal structure tubes I put in place showed that they had not been damadged very much and managed to withstand the force dropped on top of it. This means that my structure most likely could not withstand the force due to poor positioning of the internal structures, and this is why it still managed to have about half of it break. I was not happy with how my internal protection structures were placed. Due to the nature of my structure which was triangula/prism it meant that positioning of extra parts inside was extremely difficult, as it was difficult to correctly position my internal pieces without breaking the spaghetti which was very delicate. I believe that if I had managed t to use a different structure shape eg cuboid or rectangular it would be easier to position my internal protection structures within this. Leading on from this I found that the coating of the outside in paper was easy, but creating the internal structures on the inside was very difficult as mentioned due to the configuration of my initial spaghetti structure. Although not difficult, I found it quite tedious when I was wrapping the structure up with paper for the second part of the challenge as the slightest bit of pressure could have possibly caused it to snap and break in various places, meaning I would have to create it again. I overcame this problem by leaning the structure on its side instead of upright, which also ensured that there was no wobbling which would make the coating process go wrong. Overall I found the paper coating task and creation of internal protection structures the easiest task as it was more or less adding to my existing work. Also as I worked with architecture and structures during my Product design graphics GCSE in 2012, I had some experience on what would be the best way to hold something like this together with a fair amount of strength. Creating the structure in the first place was extremely difficult due to the nature of spaghetti and the many troubles adhering it.  

Time management and planning:

Concerning my time management over the course of the day, I had trouble with the first half of creating the initial structure due to the difficulty of working with my material and sticking it together with others. I feel that I could have improved my methods of planning for this structure creating by perhaps creating a 2 or 3 different models with some sticks before I go in to the real thing so that I may finish it quickly. However as this would be time consuming to create, I done a similar task by doing a quick few sketches in my sketchbook before hand, using them as models to build upon. With the second part of the task (paper coating) I did not have any problems with time as I had finished my initial structure before deadline which was at 1:30pm, giving me extra time for the second task. I could learn more from my current patterns by continuing to finish my tasks as fast as possible, in which in the extra time I have I could make alterations/variations on the existing model or develop a completely brand new one. Enhanced planning and time management will help me in my future projects by allowing me to save making time by properly planning ahead, and using this extra time to evaluate my final product, allowing me to see any changes that I may need to make or mistakes that I need to correct.
