3D Printing and its many areas of application

3D printing is an innovative technology that has revolutionized the way we create objects. This technique consists of creating three-dimensional models by successively adding layers of material, which can range from plastics to metals, to more advanced materials such as concrete and biological tissue. In simple terms, 3D printing is a process that allows you to create physical objects from a digital model. The basic principles include:

• Digital design: using 3D modeling software to create a virtual model of the desired object;
• Layering: the model is then divided into horizontal layers, allowing the printer to build the object layer by layer;
• Materials: different types of materials can be used, depending on the needs of the project and the properties required for the final object.
