Revision of module 1 & 2

My natural pattern of a spiral. My pattern reveals transformation of scaling and movement of the elements. Through the observation of the different elements, we could find them move and scale up to the same direction but different position.

Revision of module 1 & 2

1. Cut several strips of paper and fold them into the shape of semicircle. 2. Prepare an A4 size of paper as the base. 3. Stick all the pieces together from small to big and then make a shape of spiral on the base paper.

Then I start to create my paper model. It is a kind of movement that the small pieces move to different position to create a spiral.

This is the clay model I get the idea from my paper model. But I don’t want to create the clay model by separate pieces of semicircle because the clay is not as easy as the paper to stick them together. Then I tried to make the overall shape of a rise spiral which get smaller progressively and I used nicking tool to carve lines lightly on the surface of spiral. The space between lines is equal. These space looks like the semicircle.

Followed by the first method in Appendix, I made the contour in respect to front view and top view of my clay model. After I finished the digitized model in rhino, I found that there are gaps between each part(the digitized model is separated by the contour lines), it means it's not a whole. And the grid are inside the model as well which is difficult to be developed with paneling tool. Then I found that I should loft the surface of the model in perspective view and swap the inside the surface to outside to set the grids outside the model.

Front view

Top view

Revision of module 1 & 2

On the left is Times Eureka Pavilion which designed with benchmark as the main elements. We could see the light effect gets through the benchmark, the shadow of the irregular shape projects on the ground which is quite beautiful! I want to design my final lantern similarly with this light effect, the light which gets through the pattern of my lantern could make a beautiful shadow. On the left and right are Campus event space in Stuttgart. The light effect is different from Times Eureka Pavilion. The light is inside the pattern and also the lightness is different as well. I like this effect which seems quite comfortable!

These are my design using panel tool. I have tried different effects that to gain the best one so I consider what the light effect I want to achieve.

Revision of module 1 & 2

Precedents of light effects

The process of my final design

I tried pentagon, octagon and finally I decided to use trapezoid because it's easier and more suitable to create a interconnected surface on the model. Thus I developed the model with many same size of tridimensional trapezoids. Then I consider how to achieve a good light effect, I decided to make each surface of the trapezoid get a hole on it so I think when the light get through the hole model which might looks very beautiful. The underneath is the test of prototypes of part of the lantern.

This is my original clay model. We could see there are some strips on its surface and the space between each strip is like a shape of rectangle, so I just think of my final lantern what if change the rectangle into another more tridimensional shapes.

I want to test the light effect so I made just three layers of my lantern. The light effect looks good but it seems quite uniformed because of the same size of trapezoid. Thus I consider how to make it look more interesting like what if the hole of each trapezoid is different size. Then I remade another model with three layers as well.

I modified the model with the same shape of trapezoid again but it's different from the size and shape of the hole. We could see the right one doesn't have hole except the top surface and the hole on the top surface are not square shape like the before one. The new hole consist of different size of triangle so I think the light effect might be looked very interesting which is what I expected.

My final design

I have made just one layer of my final digitized model to test the light effects. Because of the different size of the hole on the top of each trapezoid, the light effect seems quite interesting and the shadow of looks quite different from the first model which has a uniformed light effect.

Unfold the model

At the first time I tried to unfold my model into a set of flat shapes. However, after I unroll the surface the pieces are overlapped with each other. Then I check it whether I put the overlapped command when unrolling the surface. I found that I didn’t, so I tried another way to unroll the surface by using the command of unroll surface. Then I succeed!

I unrolled each layer separately. Firstly, copying each layer into a new layer and then unroll them individually. Next I labelled all of the prototypes and nested them into the rectangle which required.

After I finish unrolled all the layers of my model, I subdivided the unrolled prototypes into units of triangle and delete the surface by using DupEdges command. The right picture is my final 1;1 scale of prototype. Then I nested all the prototypes to put all of them into the rectangle as required and then printed out.

Testing tab dimension and different way to stick together

After I creating the tab, I found there are some intersection between them. I tried to use Grasshopper to make a smaller size but my prototypes are quite dense so if I want to get rid of the intersection, the tab might be very small and difficult to be stick together.

What I did to get rid of the intersection is that I delete one side of tab if there is an intersection. Because I found that actually I could still stick the prototypes together if there is just one side of tab. So I tried to delete and change the size to take off the intersection.

I tried the way that just create one side of tab between two pieces of trapezoid. I found that it is much more easier to stick them together! Because if there are two side of tabs, the separate pieces can not be stick together. Then I considered to put the light inside my model which is easy because my model is like an empty cylinder so just put the light inside without dismantling the lantern.

Fabrication and material usage

This is the ivory white paper card I used for cutting cuter. I have used two ivory paper cards because I have two templates of prototypes.

The right pictures are the material I used for fabricating my lantern include scissors, scalper, solid glue stick and ruler. I don’t use liquid glue stick because it is difficult to control how much I need to use and it might makes the paper very dirty.

As well as the tape and cutting mat. As my lantern is formed by tridimensional shapes so when I use glue stick to stick them, the paper will explode. Then I used tape to stick them. Though it doesn’t look very neat, it is the only way to stick the lantern.

Prepared for FabLab

Then I started to prepare for FabLab and using paper cutter. Before I put the files into paper cutter, I need to set different layers for tabs, fold, cut, page and pen and make different lines of the prototypes into different color as required. Then stick the paper on the paper cutter to start cutting.

Process of fabricating the final model

After cutting all the prototypes by using paper cutter, tried to take them out of the paper card. Sometimes the cutter is not sharp enough so I need to use scalper to re-carve them. And then fold the prototypes followed by the dash lines to prepare for the step of sticking.

After finishing folding all of the pieces, I tried to stick them together. In my case, one prototype means one layer of my lantern, so I started to stick each layer separately and finally put them together. The trapezoids are difficult to be formed because when I stick them together they are easily explode out so I used much tape to stick them. The tape might makes the final lantern looks very messy but it is still useful to fabricate the whole lantern.

Final model with light

Because of I only have one LED light so the effect does not very apparent, but we could see the general effect that the light get through different size of model makes the shadow looks interesting. It is also a trouble to me that how to connect three LED lights together and make it hang inside the lantern, so I think if I put three LED lights together within the lantern the effect must be very good.

Process of creating vector image

Response to the reading

Architecture in the Digital Age - Design and Manufacturing /Branko Kolarevic. Spon Press, London, c2003. The digital fabrication processes start with the translation from physical to digital. Through scanning the ‘point cloud’ in the conversion software to produce the structure of the model, then setting the NURBS curves to create the surface by using lofting. Recalling the process of the fabrication of my lantern, it is quite similar that creating the surface by tracing the contour lines and then using the command loft. CNC cutting means Two-dimensional fabrication which is a very common fabrication technique. By using the water jet to cut. Laser-cutters use beam of infrared light to melt or burned the material. However, Laser-cutters could only cut the material which absorb light energy. The subtractive fabrication is to remove the specific volume of solids by using milling process. The additive fabrication is to add material through the process of converse of milling. The process is like layer manufacturing which is generated in a layer-by-layer fashion. Formative fabrication uses heat or steam to reshape and deform the shape which desired. Finally, the model could be assembled with digital technology. The cut cutter requires accuracy in my prototype in rhino, but it saves lots of time to make the model by hand and it is precise.

Digital fabrications: architectural and material techniques / Lisa Iwamoto. New York : Princeton Architectural Press, c2009. One aspect of the recent shift in the use of digital technology from design to fabrication is folding which converse a surface into tridimensional one. Folding fulfills that to create a structure and new space. The way of folding is simple and direct to be used in design that could always make new shapes and without repetition. The way of folding helps me to create the tridimensional shape of my lantern. Through folding different surface, the lantern could be formed and looks more interesting.

Reflection

The lecture of power of making outlined the ideas of scaling, making the prototypes and consider the design ways in using of architectures and the material usage. This lecture helps me to gain some information of how to create the prototypes within my model and form the ideas that what the effect I want to achieve. The lecture of digital fabrication outlines various ways and machine to fabricate our final models. It helps me choose the way which I used to fabricate my model. I used paper cutter to cut my prototypes, it is quite precise and convenient. I like the presentation of Augmented Space which presented by Roudavski. It displays some new and interesting skills which used in the computer and other technologies to create an innovative structure and models. Roudavsk also considered the problem of how to design these architectures and use the material with reference to sustainability. The idea of the design is quite interesting which opens my horizon a lot and makes me re-think the way of designing my lantern. The lecture contain the skills of using Grasshopper which is quite useful to edit the model. It helps me become more familiar with Grasshopper and gain much knowledge of how to use this tool. The reading also cover the detailed process of digital fabrication and the ideas of design by using the computer and technology. The way outlined the in the reading of Architecture in the Digital Age is also similar with the way I created my model in Rhino. A futher analysis in the reading helps me deeply understand the whole process and its function. Fabrication is the most difficult part for me that I met many problems then, like how to unroll the prototypes and set them into paper cutter, or the light effect is not I expected after I test the part of prototypes so I have to redo it. The process of trying, thinking and fabricating is very tough, however, it’s interesting as well because I feel really happy when I solve the problem and it is exciting to test the light effect every time.
