In the process of work under some serious architectural or engineering project it is often difficult to identify the various mistakes and shortcomings of using only the screen and, besides, not everyone can easily navigate in three-dimensional projections. Once you have a real physical model of the future product, you can identify and resolve various mistakes, correct the design process. The prototype can be used for marketing purposes, for advertising, when determining the cost of manufacturing, as well as to find common ground between designers and clients quickly, thereby reducing time-to-market.

Usually to obtain some models people do it by hands or by special machines. But to manufacture this model few weeks to several months are spent, resulting in higher costs for new product development and delay in the release of new products.

With penetration into the area of design technology 3D-graphics appeared and actively developing new computer technology of the so-called Rapid Prototyping, or three-dimensional printing. They provide an opportunity to receive physical details and the model without instrumental production that is by automatically converting data from 3D-representation in the physical model by pressing just one button. Thus, at the completion of the virtual 3D-model can give the command “Print”, similar to how we do it in a text editor, and a few hours or days, depending on the size and complexity of the project, obtain a physical model.

After old methods of prototyping, pre-mid 80-ies, RP-system ushered in a revolution in technology. Instead of waiting for the model for several weeks, designers can now receive them in a few hours or even minutes.

Currently on the market, there are various RP-system, producing models with different technologies and from different materials. However, all systems for quick prototyping, available today, operating on similar principles of construction of physical models, which are as follows:

• reading of three-dimensional geometry of the 3D-system (usually a solid model from CAD-systems or models with closed surface contours);

• partition of 3D-models of the simplest components or layers in cross section with a special program that comes with hardware for 3D-printing;

• construction details in the bulk structure of the polymer or layer by layer until, until will be received physical prototype.

On professional market a number of RP-printers are offered, which vary by class, price and opportunities. The cheapest are monochromatic 3D-printers, which make the model of a small amount for use in conceptual design and rapid prototyping. Prices of these systems begin with a few tens to thousands of dollars. The most expensive is a production-oriented system, which make accurate color models of large volume. The cost of such machines is hundreds of thousands of dollars.
We hope that this article helped you to understand how 3D scanning work and why it’s so popular in the modern world.

Over the recent decades rapid prototyping services managed with solving lots of tech problems happening when trying to present a product, design or model. Have you ever experienced such a problem too? Then you are welcomed to check out this rapid prototyping methodology site.

And remember that we live in the world of high technologies. Keep in mind that modern web technologies offer you a unique opportunity to try and to find anything you might require. Take advantage of them to search for cheap rapid prototyping. If you want to be aware of the latest publications on the topic subscribe to the RSS feed on this blog.
