Professional 3D Printing Service

Produzione additiva, also known as 3D printing, is a manufacturing process that creates three-dimensional objects by adding material layer by layer. It is a transformative technology that has gained a great deal of attention and adoption in various industries. Here is a professional explanation of additive manufacturing:

Additive manufacturing begins with a digital 3D model of the object to be produced. The model can be created using computer-aided design (CAD) software or obtained through 3D scanning technology. The digital model is then sliced into thin cross-sectional layers that serve as instructions to the 3D printer.

The 3D printer builds the object layer by layer as instructed by the sliced model. Each layer is typically a thin cross-section of the final object, ranging in thickness from a fraction of a millimetre to a few millimetres, depending on the chosen printing technology.

There are various additive manufacturing technologies available, each with its own specific process and materials. Some common 3D printing technologies include:

1. Modellazione della deposizione fusa (FDM) or Fused Filament Fabrication (FFF): This technology melts and extrudes thermoplastic filament through a nozzle, which moves in a controlled manner to deposit the material layer by layer.

2. Stereolitografia (SLA): SLA uses a liquid photopolymer resin that is hardened by a light source, such as a laser or UV projector. The object is built by selectively curing the resin layer by layer.

3. Sinterizzazione laser selettiva (SLS): SLS employs a high-powered laser to selectively fuse powder materials, typically polymers or metals, strato dopo strato, creating solid objects.

4. Sinterizzazione laser diretta dei metalli (DMLS) or Selective Laser Melting (SLM): These technologies use a high-powered laser to selectively fuse metal powder particles, strato dopo strato, to create metal objects with high precision.
