This past week I have decided to dedicate to the technical report. After my tutorial with Paul on Monday, I felt like I might be falling behind and so I set myself the goal of completing the second chapter of a total of five chapters. On Tuesday I was able to finally sort my problems regarding the structure of the second chapter. The chapter had moved from focusing mainly on MIT to outlining the original machines that began the additive manufacture movement and the companies who developed them into an industry. I was able to fully complete the second chapter – The origins of 3D printing and so I began writing the third chapter – The Modern 3D printer. On Wednesday, I was able to flesh out the modern 3D printer chapter, with research from a variety of sources, based mainly on the four 3D printing technologies and the different […]
Since the completion of my technical report first draft, I have been focusing on developing my concept designs for my product design project. I have acquired a set of laser pointers which I intend to test to create an arc shape in front of the bike. I have also developed some CAD prototypes of my four main concept ideas. The laser bubble was also quite successful, though I am unsure about the legality of the use of such lasers on the road.
Today I completed another interim viva in front of my tutorial group. Overall, I feel the viva was quite successful, though I did feel a little under prepared as I had not rehearsed the presentation a great deal. Unfortunately, as I was concerned about remembering what I was saying, I said “Uh” and “Umm” a fair amount of times and I also missed out some key features about one of my designs, which was quite annoying. Overall, I think that with practice, I would have been far more capable of presenting my work well, but the time to rehearse just wasn’t available due o having to work right up to the day of the presentation. I also had my tutorial with Paul regarding my technical report where I was able to tell him that I had completed my report. Paul was fairly pleased at this and we discussed what was […]
This week I have been working on further developing my five concept designs and adapting them perhaps into a single system. Overall however I do feel like I might be accidentally creating a mismatch of product ideas into a system which might not make sense or work well together. I have also been working on creating a testing rig for the 180 Light, which uses light created with LEDs diffused through acrylic to create an arc of light on the front and rear of the bike. The test right does however suffer from some stability issues due to an error in sizing the parts, which resulted in a prototype that was accidentally twice the size intended.
This weekend I have been mulling over some of the prospects for creating a design utilising the research I have attained within my technical report. Overall, I concluded that the future of 3D printing was customisable products, where a product can be customised for each user and created easily using a 3D printer. My current area of focus is revolving around medical products such as casts for broken limbs which could be easily printed per user and provide a greater degree of comfort in comparison to other products. I have also been considering items such as shoes which are often designed for the average user’s foot, but often do not fit correctly causing discomfort. I do however feel as though these products don’t quite match up to the product types chosen by the past examples I have been working from. I feel as though the work I have been doing […]
Today, I have had both my tutorial with Bethan discussing my work on my product design prototypes and my tutorial discussing my technical report design ideas with Paul. Bethan was keen that I further experimented with my prototypes to identify which design elements were successful and which could be cut. She agreed that whilst individually my designs did solve the problems arising from my brief and PDS, we were both unsure as to whether they would work as a fluid system. It is difficult to measure my work against any real criteria as the examples available are only those of my peers, who are all doing very different projects. I feel as though my work isn’t going as well as it could be, a problem I seem to be suffering from greatly this year… Paul was quite pleased with the area’s I had been looking into and proposed the idea […]
Today I have been thinking a little more about what I could be doing for the technical report design section. The idea of glasses came up when talking to a few people, where the glasses could be printed for the size of the wearer’s face instead of having a standard size. Whether this would be an interesting undertaking or not, I am not really sure, but it is an idea… Having started thinking of ideas again however, has boosted my confidence a little when it comes to designing ideas. Whilst I am still slightly dissatisfied with these ideas, it is at least something…
Over the past two days I have manufactured a new prototype for my 180 degree light design. Instead of hand making some of the more complex parts, I decided to 3D print them to get perfect accuracy for holding all the parts. The design is quite simple, with 4 RED LEDs diffusing light through the two acrylic arms. At first, I used a permanent battery pack, however I later decided to hook up the arduino and distance sensor. To test the prototype, a friend and I cycled down the incredibly busy Newport road in Cardiff with a camera watching the back of the bike: [youtube https://www.youtube.com/watch?v=svTkHRqegU8&w=420&h=315]
Today I decided to further develop the laser bubble prototype design, by 3D printing a prototype to attach to the bike. I have previously tested the prototype, but due to the makeshift creation of the original prototype, the laser emitters being used were almost broken. The prototype was printed using ABS which will hopefully prove to be a strong structure, which should keep the lasers from damage. The prototype easily twists and locks into the holder which can easily be attached to the bike on any tubular surface.
Today hasn’t been exactly excellent. Unfortunately, all the lasers that I was using in my laser prototypes have broken and are unavailable to buy again. Since this design is no longer feasible within the time frame I have left, I have decided to turn around the project and focus on the skeleton suit design. I have given more thought as to how the design might work, remembering a technology called electroluminescent wire aka EL Wire, a lighting technology similar in a way to flexible neon lighting. I am going to try to develop this further and see where it takes me…
