Tutorial 2
Second tutorial
Shoes - Interdisciplinary Skin
Process
Step one - Create the real model for the object
In this step the main principal is similar like the first tutorial that i have been presented before. Form 123d catch, meshmixer to the 123 make and finally use the illustrator and laser cut machine to generate the basic skeleton model.
Step two - make the metal surface
Before showing the main part of this metal sheet making, i want to use the simple word to say the initial process.
1. Select the right the aluminium sheet with the appropriate thickness.
2. use the marker to draw the basic shape of the object on the surface of the sheet
3. cut the shape with the cutter that exist in the worklab
Main part
For this new shape, instead of using the round hammer as the starting point to bend the sheet like what i showed in the first tutorial, i decided to use the roller first then use the hammer.
Use this hammer to shrink the outer sheet moves inward
Then dividing the sheet into 3 different parts and treating these three different parts with different making methods
First part - bottom part of the shoes
First part - bottom part of the shoes
Use the iron ball as the supporting equipment to help us make the bottom round surface
Second part - middle part of the shoes
use the wooden stake dolly and the hammer to create this part
Third Part - Top part of the shoes
In this case there are two steel dolly that will being used the first one is to generate the general bending for this part while the second one which is much smaller is used to adjust more detailed part.
Final result
Tutorial 1
First Tutorial
Snail - Bionic architecture
Step one: Create the 3d model through the 123d catch
1. Download the 123d catch app from the phone's store
2. Create an autodesk account to make sure that you could have your own database to store your 3d models.
3. Watch the tutorials that have been given on the Internet to understand how to use this software.
(Below is the link of the tutorials)
http://www.123dapp.com/howto/catch
Step two: Create the real model
1. Open your account from the 123d make official website and download your selected model
2. Fix the model's problems by using another software which is called as the Autodesk MeshMixer to make the model becomes a solid one instead of a skin model
( in this case you could change your model shape as well to generate a more beautiful one)
3. Open your finilised model with the 123d make
(In this case red pieces mean there are something wrong with this model and we have to change the numbers of the cutting pieces through the vertical and horizontal way until there is no red appears.)
Another important thing that i want to mention is the thickness option in the 123d make. In order to make it easier to assemble the model the selected thinkness should be a little bit bigger than the thickness of the material that you are going to use. Like setting 3.2mm gap to suit the 3mm thickness materials,otherwise it is quite hard to assemble the model.
4. Export the finilised sheet to dxf files and change the lineweight and color with the adobe illustrators. - Change the cutting line to red and the number line to blue; change the line weight to 0.001.
5. Assemble the whole pieces and got the final model
The new made metal surface
The original one
Process
Draw the appropriate shape on the sheet
Fix the position of the sheet until the line, cutter and your eyes at the same level
First cut the square shape with the lager cutter then use the smaller one to trim it
Cut the rest part of the sheet with this cutter
Get the final round shape
Draw the circule at the center and use the hammer that i showed above to bend it
as the first step to create a dome like shape
(Tip: hammer from the center to the outside, round by round)
use some other equipment in the work lab to help us create the shape
Pictures show how to use these two equipment
(Tip: Please notice the difference between the hammers that i used before, the circular shape hammer is being used to create the first bend as the starting point while the hammer that i showed above has the smaller and rectangular shape at the top which is being used to push the sheet move inward more deeply)
The basic shape has been created
using the Roller and shrink to make the beautiful skin
Pictures show how to use this two equipment
(Tip: for the roller remember to change the gap between two roller to suit the thinkness of your selected sheet; for the shrinker we need to do it slowly and carefully otherwise it will be quite easily causing the sheet to crease too much. If it is over-shrinking, it is very hard to fix.)
The dome like shape then could be generated
Use the marker to draw the whorl on the surface
Get the suggestion from the staff in the workshop and he taught me a good way to make the whorl, which is using the club to pat the surface.
Here is the result.
Then these three hammers will be quite important for the rest metal making
Pictures show how to utilize these three different hammers
(Tip: For different whorl gap we need to select the suitable hammer to achieve the different purpose like use the big and round one to suit the starting point of the whorl while using the smaller one to create the top of the whorl and each two hammers could being used together by cooperating with the equipment that showed in the third picture)
Also here is another tool that could being used
Final Stage: Using the square shape hammer to clean the surface of the sheet
- try to remove the hammer markers on the surface
- use the methylated spirits to clean the marker evidence
- use the sandpaper to clean the surface
( Tip: the most important thing in this case is the sandpaper, only if you have quite successfully used the square hammer to smooth the surface, then do not use the sandpaper to clean the surface. Otherwise the surface will looks very ugly

Reflection
Compared
with my first Project which is to create a dome-like metal sheet to cover the surface
of the shell, the new one for the shoes is much more difficult than I expected.
And the reason for this is for my first one, there’s only one main making principal
which is to hammer the surface from the inner centre circle to the outer
surface and make the whole flat metal sheet moves inward. All I need to do for
the main part is to be more patient and hammer the surface slowly in a circular
way. Also by cooperating with the round iron equipment that exists in the
workshop, the final purpose could be easily achieved.
While for
the new one, it can be easily noticed that there are a lot of curved like surface
on the shoes and more importantly, the curved direction for some part of the surface
are in the opposite way like one part of the surface requires to make the round
surface moves inward while for the rest attached part needs to move outward. In
the case, the intersecting part of the metal sheet could be easily broken up. In
order to solve this kind of conflict, I always used the maker to draw the
auxiliary line on the surface with the laser cut object and slowly hammer the
surface to make it as accurate as possible to suit the object.
Although
the final result is not as good as what I expected. I still think that if I have
another chance to make this surface, I could do it better and maybe I could
change another way to make the surface like to make another solid and rigid timber
model for the object then I could hammer the sheet directly on the surface of the onject. I guess through this way the final surface will be better to suit.
Overall the
new one gives me a quite different experience for the metal sheet making. After
this project, it actually helps me improve my metal sheet making skill and push
me to learn more equipment inside the workshop.
Porject 2
Process one
Paired up and get the model
Paired up
Cooperating with another student who study the interior architecture course. We simply shared our own adobe illustration files for the first project. For his first one. His chosen object is the basketball shoes, which was being used as the inspiration source to explodee ‘Highlight in the dark' concept for his second year restaurant interior design, with the idea of the curved surface and the dotted light.
Assembly
When started to combine every units into the whole. The first thing that we need to do is to classify two groups, one of which is called the 'Z' group with the capital 'Z' half cut on the surface. This group will be assembled in the horizontal way later for the final model. Another group is called as the 'Y' group which will be assembled in the vertical way. Then we need to interlock each two pieces with the same number like Z-1 intersect with Y-1 and etc. And after we interlock all of the different units. We will finally get the final model.
Process two
Working Process - make the skin
1. Choose the right material and cut it at the appropriate scale.
2. Use the roller and the hammer to make the initial curved like shapes, case marker will be used to guide the way to show where the hammer should go. And the picture showed below is my initial approach.
3. Use other iron ball equipment to help me get the more detailed curved surface
