Products for rapid prototyping. Rapid prototyping takes virtual designs from
computer aided design (CAD) or animation modeling software. With additive fa-
brication, the machine reads in data from a CAD drawing and lays down succes-
sive layers of liquid, powder, or sheet material, and in this way builds up the
model from a series of cross sections. These layers, which correspond to the
virtual cross section from the CAD model, are joined together or fused auto-
matically to create the final shape. The primary advantage to additive fabri-
cation is its ability to create almost any shape or geometric feature. The word
"rapid" is relative: construction of a model with contemporary methods can take
from several hours to several days, depending on the method used and the size
and complexity of the model. Additive systems for rapid prototyping can typically
produce models in a few hours, although it can vary widely depending on the type
of machine being used and the size and number of models being produced simul-
taneously. Rapid prototyping is now entering the field of rapid manufacturing
and it is believed by many experts that this is a "next level" technology.


In this abstract forms of shapes are generated by accident. A simple shape was
made (savoy vase) and various parameters of displacement were defined. Afterwards
this "explosion / displacement" was animated. In every second of this amination a
new shape is generated and could be theoretical manufactured.
