Introduction In module 2, we explore the idea of personal space where people are able to avoid situation that might cause discomfort in term of personal space. This idea is rather to prevent any upcoming invasion of personal space. This concept then provide the basis to our design, where it prevent direct eye contacts and avoid the movement of shoulder joint to prevent any further body contact, for instance hugging.
M2 PROTOTYPES For M2 prototype, we produce one part of the design, and we choose the head part. The way this design is fabricated by having triangular panel being laser cutted with tabs to join one panels to another. As we having 2 parts in the design, it is questionalble whether it is necessary to have 2 components, whereas it is possible to have both component combined. It is also commented that our design have to much fashion references as the body part is symmetrical. The downside of the prototype also it keeps on sliding while people wearing it, so the design M2, we will be adding more panels so it will not slide off from the head.
Design development + fabrication of Prototype V.2
As it is questionable whether it is necessary to keep the head and body part separated, we decide combined both head and body part for M2. We also add openings to the body part where in the previous design in M2 there is no opening. The opening are in various size in a rondom manner. For the protoype, we still using the 290 GSM ivory card and also we decide to add tranlucent materials in blue and red colour in the openings. The design for M3 is covering the upper body with the heart area exposed. As the concept in M2 is a best friends get into a fight and meet again in the future, we keeps the heart area opened, symbolizing the person is ready to accept the person in their life again.

Digital Fabrication Process - From physical to digital The process of a physical model to digital model is a way of transtation. The geometry of a physical model can be represented by digital form by using several fabrication machines such as Three-Dimensinal scanning. A common method for it is the use of a digitizing posi tion probr to trace surface features of the physical model.Digital Fabrication includes 3D fabrication, 2D fabrication,Subtractive, Addictive and Formative fabrication and assembly. ďżźďżź
Subtractive fabrication It removes a specified volume of materials from solid using electro-, chemically- or mechani cally-reductive (multi-axis milling) processes, for instance laser cutting. Addictive fabrication Addictive fabrication is forming by adding material in a layer-by-layer fashion. It is as the converse of milling. The example of it is 3D printing. However, there is rather limited application in building design and production because of limited size of objects, costly equipment and lengthy production times. Formative fabrication In the formative fabrication process, in order to get the desired shape, mechanical forces, restricting forms, heat or steam are applied to a material.
Reading applied to design We used laser cutting during our fabrication process. It helps us make the digital model to physical model more efficient. It also helps us cutting the material with accuracy and neat clean cut. With such time efficient method of fabrication, it allow us to have time to test different materials and see how it works. We used Ivory card 290 gsm because it is firm and easy to bend. In addition, laser cut allow us to etch curve, so the panels have clear folds which can shows the sharpness of our triangular shapes.

Reading Response Wk 7 Describe one aspect of the recent shift in the use of digital technology from design to fabrication?
With digital technology, the way of thinking and doing, design, fabrication and prototype are being blurred. Therefore it allows a quick design to produce a prototype. It is also mentioned that with digital technology, it allows design to have a complexity and uniqueness and did not significanlty. To fabricate the design, it is also common to use subtractive fabrication like laser cut and additive fabrication like 3D printing which means less labour intensive. As it is also very important to represent the design itself in an orthographic projections, with digital technology it will be easier as people just have to take the section by cutting through the 3D objects.
Reading applied to design Referencing from the lectures and readings, what is the implication of digital fabrication on your design ?
With digital fabrication it allows an in depth apperance on how the design looks like with an accuracy between drawings and 3D models. With those in depth appearance, it enable us review our design without actually fabricate the physical model which saves us a lot of time as our model is built from an individual triangle. After we are satisfied with our design, then we laser cut it and assemble it. Without digital fabrication, to built our object will require a lot of time as we need to measure all triangles one by one and cut it, then assemble which may occurs some errors during the process of measuring and cutting. With digital fabrication, it allow us to skip the measuring and cutting process and just directly to the assembling process.
As in our M2 design, we did not use panelling tools to create the design. So in M3, we wanted to use panelling tools to make our design, however, as our panelling tools is very basic and we are using triangles which somehow harder to use compares to square or rectangle, the outcome of the design using panelling tools did not match with our expectation, as we wanted a more angular design but we cannot create holes and when we create holes, the design is more curvy rather than angular. The triangles generated by panelling tools is made using mathematical sequence and it creates some sort of regularity to the design. Therefore, rather than using panelling tools, we decide to do the design manually.
Prototype Development To fit the personâ€™s body properly without sliding off easily, we decide to add more panels to the back part of the head and body.
Prototype optimisation In M2, we are using white ivory card 290 GSM. We are happy with the material that we used however, we are curious about the outcome if we use thicker materials as it may creates a sturdier. So, during the fabrication of the prototype for M3, we experimenting a 1 mm mountboard. However, we found that the material are tearing when the tabs is folded, even though we already put etching in it, which results a rather messy models. With these material the model become more rigid, however it makes people harder to wear it and prone to tearing the model as it does not gives flexibility compares to ivory card.
One questions that were given to us during M2 presentation is that how are we going to make our design different with othersâ€™ design as there are several group are doing the same concept with us. Then, we are brainstorming about what to add to make our design different with others, and come up with an idea to incorporate colours to the opening. The colour is added by having a transparent coloured sheets. The colour that we choose is blue and red. With the colour we choose, we are able to explain our concept deeper as it is related to the emotion that we wanted to show in our design.
As we experimenting with colours, we wanted to try using black colour as the base by using black optix card 300 GSM. However, we found out that when the glue oozing out from the tab, it very visible compare to using a white materials. This results a messier model compare to white, and we also prefer the contrast between white and the colours compare to black and the colours as with white, the colour is more popped-out.
Initially, we stick the colour sheet in random manner, but then, we try to use the colour to express the emotional aspect from the personal space concept that we have, which results a gradual transition from blue to red. The thinking behind this arrangement corresponding to our personal space concept where friends having a fight and meet again in the future and have to work with each other. The blue represent calmness, and red represent warmth. The purple colour is the transition colour from both colors. The blue colour to calm down the anger in the head, and the red part to warm up the heart to .
In order to have the colour stand out more, we decide to make the opening bigger towards brain and heart. As it is described previously, it corresponding with the symbolic meaning towards the concept that we have.
Problem During Fabrication Process Some problem occurs during fabrication of the prototypes as our model is upside down, where the tabs are exposed. Initially we thought that we are carelessl with the plane in the rhino. This results the unrolled panels are being flipped and when it is laser cut, the direction of the etching becomes the other way around. However, after refering to the 3D model, the problem turned out to be how we join the tabs. Thankfully we are able to notice the problem and fabricate the physical model similar to the 3D model.
