Module 3- Week 8 Evelyne Setiono Student No: 579870 Semester 2/2012 Group 3


Lecture and Reading This week's lecture is presented by Paul Loh and he talked about the Power of Making. This was related to the phase of this project which is fabrication. He explained about the importance of prototyping before making the actual model by giving some examples of his past projects with different scales of prototype. Creating prototypes is useful to know the dimension and the material of the actual model, and also to reduce mistakes in the final model. Prototypes can be physical or digital. Physical prototypes are models which resemble the model in real life, while digital prototype is creating the model in computer using digital software, such as Rhino and Grasshopper. From this lecture, I learn that prototyping is very important to measure the success of the final model. The reading “In Fab: The coming revolution on your desktop- from personal computers to personal fabrication� by Gershenfeld, N tells a lot of information about the digital technology of fabrication process. Nowadays, due to the development of technology, fabrication can be done using computercontrolled cutting tools which provide quick thrill in physical fabrication. One of these tools is laser cutting. High-powered laser cutter can cut thicker and stiffer materials, such as metal or stone than low-powered cutter. The laser cutter can be useful in fabricating many and large objects, however, it can also be dangerous if it cuts flammable materials or toxic-emission materials.


Evaluation Based on the evaluation I made from the final model I've created on Rhino in module 2, I decided to refine the model to suit its function. Some evaluations that I made are: 1. Less opening/ holes This can be done by changing the body part into solid panelling. This way there will be sufficient light for the lantern. 2. Choose suitable materials used for the lantern I decided to use black card as the material. 3. Try different prototypes 4. Size and scale I have to think about how the lantern is worn/ held, for example measuring the width of my neck or shoulder. 5. Improve presentation method I can do this by having a chronological explanation, explaining some interesting observations and analysing more in the process.


Refinements

For the first refinement, I began in the first process again which is creating the point grids and splitting the model into three parts. The above pictures are the result of the splitting.


Refinements After that, I refined the head and tail parts' pattern so that the folding lines are not too thin. In order to solve this problem, for the head part, I moved the triangular holes closer together by 30mm. Then, I extrude the surface by 10mm. The finished pattern then place on the head part on the model as 3D custom panel.


Refinements I did the same thing for the tail part, however this time, I offset the triangles by 15 mm and move them closer by 50 mm each. I wanted to make the triangles smaller so that there is significant difference with the head part.


Unrolling After I did all the refinements needed, I found out that the body part was a little bit tricky. When I wanted to panel it using 2D custom panelling, the result showed no surface on the panel. However, when I tried to panel it using basic panelling, such as box and triangles, the result showed different result. It showed the surface and the panelling is successful. Therefore, I decided to concentrate on unrolling the head and tail part first because these are the main point of the lantern.

Tail

Head


Unrolling The tabs are 10mm away from the unrolled section. This is the same distance as the thickness of the 3D pattern of the model. The unrolled sections are shown below:
