Survey Respond about 3D Printing

Most of the answers tell us that people like 3D printing and soon it will be very common in industry. 

PRESENTATION PREPARATION

In this class, our teacher divided into groups of 3. I was with Alina and Abdul. So, we was grouped randomly to present our preparation of presentation. However, no one way ready at that time because, Alina and Abdul had their presentations in last week. But mine was before last week, so I break the ice and started to speak. I explain about my main idea and talk about how to manage my time. Then Alina show confidence and began. She told us about the concept of her presentation topic and also she talk about time management. Now, that was Abdul's turn, he had his topic but he was not confirmed about his main topic. So, he discuss rather than present. but he talk about his research and said that he going to decide soon about his topic.

Natalia gave us feedback on it as well. 

3D PRINTED DRESSES

INTRODUCTION OF CASE STUDY

An Israeli fashion designer proved that, “forget shopping, soon we will be able to download our clothes” (Peleg, 2015). Danit Peleg born in 1988 in Israel. Danit Peleg is a fashion designer based in Tel-Aviv which created the first commercially available, 3D-printed clothing. Peleg studied Fashion Design at the Shenkar College of Engineering and Design. Her dissertation researched the possibility of 3D-printing clothes. In 2014, she designed her first 3D-printed jacket, the Liberate, after a lot of experimentation with different materials and setups. After this initial success, she created more designs to create a complete collection. After graduating in 2015, she started her own studio, via which she provides custom, 3D-printed designs for clients. In 2016, she designed a 3D-printed dress for Amy Purdy, who wore this dress during a dance performance during the opening ceremony of the Paralympics of 2016. In 2017, a limited edition-set of 100 Bomber jackets were created. For $1500 apiece, clients could get their own customized jacket printed. Peleg organized a three-day work shop on 3D-printed fashion in 2018, where 15 students from all over the world could learn about her design process. That year she was also recognized as one of Europe's 50 most influential woman in tech by Forbes.

CASE STUDY

In this class, Natalie introduce us about Case study. She told us that, we need to select a topic and prepare our case study. After that she gave us some time to research about our topics, then she divided us into groups of 3. This time I was with Adaku and Alina. Adaku starts the conversation and told us about her research, she had a lot of research, me was a bit shocked that she completed her plan in no time. Well Done Adaku!
Now, Alina told us about her topic and she also had some research on voice recognition. She said that, she did some research and she have a few good examples to add. Between this conversation Terez join us and she showed us her case study, that was a sample of case study which was well written and almost a perfect example. She also offer that if anyone want this I can send, then she leave.
Then I started to speak, I had no idea about, How to write a Case Study, So, I told them it's my first time. Then Adaku explain me about the concept of this report study. Moreover, I already had research on my essay, So, I managed to speak about my Case Study.
 

EXTRATERRESTRIAL PRINTED STRUCTURES

The printing of buildings has been proposed as a particularly useful technology for constructing off-Earth habitats, such as habitats on the Moon or Mars. As of 2013, the European Space Agency was working with London-based Foster + Partners to examine the potential of printing lunar bases using regular 3D printing technology. The architectural firm proposed a building-construction 3D-printer technology in January 2013 that would use lunar regolith raw materials to produce lunar building structures while using enclosed inflatable habitats for housing the human occupants inside the hardshell printed lunar structures. Overall, these habitats would require only ten percent of the structure mass to be transported from Earth, while using local lunar materials for the other 90 percent of the structure mass.

The dome-shaped structures would be a weight-bearing catenary form, with structural support provided by a closed-cell structure, reminiscent of bird bones. In this conception, "printed" lunar soil will provide both "radiation and temperature insulation" for the Lunar occupants. The building technology mixes lunar material with magnesium oxide which will turn the "moon stuff into a pulp that can be sprayed to form the block" when a binding salt is applied that "converts [this] material into a stone-like solid." A type of sulfur concrete is also envisioned.

Tests of 3D printing of an architectural structure with simulated lunar material have been completed, using a large vacuum chamber in a terrestrial lab. The technique involves injecting the binding liquid under the surface of the regolith with a 3D printer nozzle, which in tests trapped 2 millimeters (0.079 in)-scale droplets under the surface via capillary forces. The printer used was the D-Shape.

A variety of lunar infrastructure elements have been conceived for 3D structural printing, including landing pads, blast protection walls, roads, hangars and fuel storage. In early 2014, NASA funded a small study at the University of Southern California to further development.

the Contour Crafting 3D printing technique. Potential applications of this technology include constructing lunar structures of a material that could consist of up to 90-percent lunar material with only ten percent of the material requiring transport from Earth.

NASA is also looking at a different technique that would involve the sintering of lunar dust using low-power (1500 watt) microwave energy. The lunar material would be bound by heating to 1,200 to 1,500 °C (2,190 to 2,730 °F), somewhat below the melting point, in order to fuse the nonparticipant dust into a solid block that is ceramic-like, and would not require the transport of a binder material from Earth as required by the Foster+Partners, Contour Crafting, and D-shape approaches to extraterrestrial building printing. One specific proposed plan for building a lunar base using this technique would be called Sinter Hab, and would utilize the JPL six-legged ATHLETE robot to autonomously or telerobotically build lunar structures.

3D PRINTED BRIDGE

In Spain, the first pedestrian bridge printed in 3D in the world (3D BRIDGE) was inaugurated 14th of December of 2016 in the urban park of Castilla-La Mancha in Alcobendas, Madrid. The 3D BUILD technology used was developed by ACCIONA, who was in charge of the structural design, material development and manufacturing of 3D printed elements. The bridge has a total length of 12 meters and a width of 1.75 meters and is printed in micro-reinforced concrete. Architectural design was done by Institute of Advanced Architecture of Catalonia (IAAC).

The 3D printer used to build the footbridge was manufactured by D-Shape. The 3D printed bridge reflects the complexities of nature’s forms and was developed through parametric design and computational design, which allows to optimize the distribution of materials and allows to maximize the structural performance, being able to dispose the material only where it is needed, with total freedom of forms. The 3D printed footbridge of Alcobendas represented a milestone for the construction sector at international level, as large scale 3D printing technology has been applied in this project for the first time in the field of civil engineering in a public space.
