3D printers are  additive manufacturing machines, that is, they manufacture an object, layer by layer, by depositing, solidifying or agglomerating, respectively, material in filaments, liquid or powder. Unlike classic machine tools, which allow you to make a piece by removing material through mechanical processing, 3D printers create objects by adding successive layers of material. In addition to reducing production times compared to traditional manufacturing processes, such as mechanical processing, 3D printing guarantees high precision in the creation of complex shapes brass polish machine singapore.

Unlike molding, in which it is first necessary to create a mold, these machines operate directly from a digital model that is cut into “slices”, and in which each “slice” corresponds to a layer of material.

What are the main applications of 3D printers?

3D printers were first used in the industrial sector for prototyping, but the medical and dental sectors quickly became interested in this technology, both for bioprinting (fabrication of cellular structures) and for the fabrication of prostheses.

Even industries related to transport , such as aeronautics , aerospace , maritime transport and automotive are increasingly turning to 3D printing because it allows the creation of lighter pieces with equivalent, if not even superior, characteristics compared to those manufactured in the traditional way.

This technology is also widely used in the field of architecture and civil engineering , in the making of models as well as in the construction of buildings and infrastructures, for example in the construction of bridges.
