Re(Calibrator) Phase8

Recently, Rapid Prototyping (RP, also referred as 3D printing) is becoming a more accessible technique for quick fabrication of a computer generated part or assembly. I decided to try it with the geometry that I have been developing, which would give me a tangible representation of the new structure.

The mesh view of the improved geometry

In order to go ahead with the Rapid Prototyping, the entire geometry of what I have designed so far needed redesigning. I had to make sure that none of the components is thinner than 0.1mm; otherwise those elements would have collapsed during the "printing" process.

The latest geometry in glass

The RP process, is also known as the layered manufacturing, since this is exactly how the solid object is "printed" with the help of layering. The RP chamber uses a particle dust; a thin layer of that powder is spread on top of the printing surface and an inkjet printer then deposits tiny amounts of the binder solution (this is controlled by the software). This solution binds the dust particles only in the places where it is needed, thus creating a 3D object.

It is true however, that the RP fabrications are generally test products, as the RP materials usually do not have enough strength or durability. In very few cases only, the RP models are the end products.

Having said that, there is an emerging trend towards RP in different materials, such as the experiment conducted by the team of engineers and artists at University of Washington.

Powdered glass RP by University of Washington

At the Solheim Rapid Manufacturing Laboratory of Washington University, this team has developed a technique, which they call Vitraglyphic process, which allows them to print tiny particles of glass powder. http://www.physorg.com/news173022660.html  The team came up with a new approach for both the dust and the binder. At this stage, the end product does not look much like glass, however it held together and fused when heated in a kiln. Needless to say that the Washington technique is just one of the explorations of the massive potential of RP fabrication, however at the moment it remains a very expensive and a limited method. 

The desired glass structure to be achieved

The glass structure that I am pursuing, would retains its translucent, reflective and refractive qualities, and I am hoping to achieve this combining the 3D modelling, RP and craftsmanship.
