Final Assignment

For our last assignment we worked with the same principals as assignments 5, adaptive formwork. We wanted to test how to make a more complex form than we did in assignment 5 so we decided to cast an animal more specifically a dog, Scottish terrier. We choose this method because it was able to give us a given form.

 

From a porcelain figure (pic 1) that we photographed from different angels we attached it into a 3D program called silo (pic 2). Then we used pepakura to unfold the pattern onto a layout (3). We laser cut the pattern on sheets of milk paperboard and folded it together to a dog Lasse-Babak (4,5,6).

Then we placed the paper formwork in a bucket and filled the bucket with small aggregate and the form with large aggregate (7,8).

 

From our previous experience from assignment 5 we realised that we needed to adjust the recipe. When mixing the slurry we added about twice the amount of suggested water to get it flowable, more precisely 450 g of water per kilo cement (9). We also did this in different layers because we resonated that it will be the smartest way to get the slurry to pass through the large aggregate in all the small parts.

Since the bucket was a little too small for our formwork, we stabilized the sides using plastic cups filled with sand. (10)

Two days later we removed the formwork and Lasse-Babak was born (11-16).

Assignment 5

For the form we used hard plastic to fold a diamond shaped form.
When mixing we realised it was too dry, so we added water little by little, eventually ending up with twice the suggested amount.
We thought that the slurry would be able to flow through the aggregate, but when we took it out of its form only the upper half had successfully been shaped after the form, the lower part was unfortunately not reached by the slurry.

Assignment 4

For the forth assignment we chose the topics “Impressions” and “Textures”.
We started by doubling the default recipe. After mixing we thought the mix was very dry and almost doubled the amount of water ( +250 g) and that made it smooth and easy to pour into our forms.
Impressions: For this category we used a silky fabric and placed to cups in different heights. The result was a smooth surface with quite good detailing.
Textures: Here we used a laced fabrique with quite big holes and a sheer fabrique under to keep the mixture from leaking. In the result you could clearly see the pattern of the lace.

Assignment 3

We started by mixing the default mix and then dividing it in three parts, keeping one as it was and adding different amounts of water to the other two mixes.
mix 1 – default
mix 2- default + 6 g water
mix 3- default +  13.3 g water
We then “poured” half the mixes on top of plastic cups and kept half.
An hour later we poured the rest on cups. The first mix (1.2) did not change much. The second (2.2)  had become more fluid and the third (3.2) had become less fluid.

Group 4 – Assignment 2

Mix 1

Cement           62,5 gr

Sand               168 gr

Water             25 gr

 

Mix 2

Cement           62,5 gr

Sand               187 gr

Water             25 gr

 

Mix 3 – Blue

Cement           62,5 gr

Sand               187 gr

Water             25 gr

Pigment          2,5 gr

 

Mix 4 – Red

Cement           62,5 gr

Sand               187 gr

Water             25 gr

Pigment          2,5 gr

 

Mix 5  – Black

Cement           62,5 gr

Sand               187 gr

Water             25 gr

Pigment          2,5 gr

 

All of the five mixtures were basically the same mix (default mix) except for the first, which had a bit less sand in it. It was not more fluid and than other ones and all of them were not fluid, they were more stiff and grainy. Because of the scales lack of precision we accidently poured too much pigment in mix 3-5. We learned that for next time; get more accurate result, we need to have larger proportions and/or better scale.

Dune

Made by: Rainer Mutsch

Material: Fiber cement

Process: Produced by the company Eternit fiber-cement is a very durable, fully recyclable material consisting of 100% natural materials like cellulose fibers and water.

Each Dune element is 3D-molded out of one whole fiber-cement panel, the cut-offs are thereby reduced to a minimum.

Botanical Casts

Made by: Rachel Dein

Material: clay, plaster

Process:  She makes impressions in wet clay, and then pours plaster directly over it. The clay captures the most intricate details. Each clay mould can only be used once, making every piece unique.
