How works 3D prototyping for casting of plastic?

The term "prototyping" is a wide concept. The current version of the future car can be called a prototype - this is its functional prototype. The plaster figurine of the product, which reproduces only the geometric dimensions and shapes of the future part, is also called a prototype, although it is rather a layout.

In preparation for production for casting polyurethane products, the prototyping method is also used, or rather 3D prototyping. This is a technique for creating a physical object based on its digital 3D model. At the same time, there are such concepts as "rapid prototyping" and the "prototype" itself.

Prototyping technologies used in Marabu

Among many different technologies, Marabu has chosen for itself the following most demanded on the market:

FDM printing – this method consists in layer-by-layer growth of a product from a plastic filament that has been previously melted. Suitable in cases where a product needs to be made quickly without high requirements for the quality of the final product. In addition, this type of printing is justified when the model has large overall dimensions or large volume. At the same time, it is necessary to carry out a large amount of work on mechanical surface finishing and painting. With a help of this method is difficult to manufacture parts of a complex structure with small elements. But it is already possible to assess the ergonomics, the conformity of the form to the ideas of the designer. You can understand the real weight of the finished product, evaluate the design, and determine the hardness, the required elasticity. In this case, the growing period is measured by hours.
