As part of my dissertation, which I have titled “CTRL P – The Next Industrial Revolution”, I was testing ways of 3D scanning and printing my hand for the front cover of my hardcopy dissertation. The hand is making the movement one does when pressing ‘ctrl + p’ on a keyboard.

Carl Deckard (left) and Joseph Beaman (right) invent the printing process SLS (Selective Laser Sintering) in 1987; just 4 years after the inception of 3D printing, with Charles Hull patenting STL (Stereolithography). It is incredible to think that this technology has been around for over 30 years and has only just entered the wider consumer market. However, today it’s been said to be the Next Industrial Revolution, a revolution after all.

After reading and hearing about the infinite possibilities of complex structures using a 3d printer one would think it is quite easy to simply create a complex structure layer by layer. Most 3d printers available for the general consumer are based on FDM. However, what happens if there are overhangs, arches, etc? The printing material would simply drop into emptiness until it hits something solid (the base platform or part of the already printed object). The solution for this is SUPPORT MATERIAL, usually a softer material, different to the object material so it can be easily removed or a water soluble material (i.e. PVA, Poly-vinyl alcohol).
This is my first 3D printed object; using my friend’s 3d printer and CAD program we printed a letter K (for Kiera). I was able to learn about the program and print process and got a clearer understanding of the different aspects one has to consider when 3d printing, i.e defining the thickness of each layer (in this case 0.3 mm), the fill density, infill speed, travel speed, nozzle diameter, etc.

I just recently went to see the film ‘Elysium’ in the movie theatre, a science fiction action-thriller film depicting the state of the world in the year 2154, over populated and taken over by androids and robots. After reading about this project by German based firm ZA Architects the story doesn’t seem as sci-fi anymore…
Unlike rival proposal by Foster + Partners, which involve building layers of soil up around an inflatable frame, the SinterHab concept is based on a system of rigid modules that can be pieced together to form a structure. Inspired by the formation of bubbles found in nature, the architects have developed a process that will enable the construction of flat walls and surfaces, based on the geometric rule that neighbouring bubbles must be in equilibrium.
