3D Rapid Prototyping

3d rapid prototyping is precisely categorized as array of technologies through which the production of a specific model of any component is possible. The selection of component can also be done with more advanced CAD (3-dimensional computer aided design) data.

To be precise and clear, the computer generated design generated using the 3D design software package is quickly translated into highly specialized thin horizontal layers. The process of creation of layers is done one at a time and a precise picture of real physical model is designed.

The Possibilities of 3D Rapid Prototyping

Rapid 3d prototyping is based on the process of - "What you see; is what you get," meaning, the virtual model is similar or almost near to the physical model. The rapid 3d prototyping technology provides fundamental advantage in comparison to traditional types of techniques.

With the use of this creative technology, it is possible to produce highly effective geometric feature or shape of any kind. The best thing to note about 3d rapid prototyping is that geometric shapes can be created in variety of colors as well as structures.

The word Rapid used in rapid 3d prototyping has significance in the sense that there are some specific 3D printed models, which can be generated in just matter of hours. The time taken for building a realistic model is directly proportional on the complexity, size as well as the technique put into practice.

Several types of methodologies are used for deposition of the materials. Few of the prominent ones used are:

  • Stereolithography (SLA)
  • Selective Layer Sintering (SLS)
  • 3D Printing (3DP)
  • Fused Deposition modelling (FDM)

All the above methods need support material which will result in the production of tapered surfaces as well as overhangs. The support material is available in variety of forms, the significant ones include specially designed powder, wax, liquid, and model material, which later on be removed and cleaned from the model afterword. There some printing machines which generate the support material with the help of specialist software.

One of the many interesting facts about the rapid prototyping is that the models generated have superior production value and high finish. In addition, the prints can be used as production parts in a particular scenario.

You could easily think of the machines that are advanced and too compact to fit on the desktop and even quite big in shape that have the capability to print the entire engine block, without even doing any hard labour.
