What is 3D Printing
What is meant by 3D Printing.
La Stampa 3D, also known as additive manufacturing, is a particular technology that allows you to create physical objects in three dimensions starting from a digital model, usually from an STL type file. This process occurs through the deposition of materials layer by layer, to form the desired object.
3D printing has revolutionized many industries, including the design, Medicine, architecture and the manufacturing industry. Thanks to its flexibility and its ability to produce customized objects, it also opened up new possibilities for rapid prototyping, small-scale manufacturing and custom manufacturing.
This additive technology can be used to make prototypes, replacement parts, custom items, gadget, toys and much more. There are different types of 3D printers and materials, depending on the printing process and desired properties.
How 3D Printing Works.
3D printing works by exploiting the different technologies available today, each with its own characteristics and performance. Some types use rigid materials such as ABS, the PLA, it PET-G, RUBBER type such as TPU and others also called TECHNICAL. come il Nylon, Carbon and Polycarbonate. The most advanced and expensive models, instead they can print with metallic materials, ceramic and even organic, for food use and for contact with skin and mucous membranes.
The most popular 3D Printing Technologies.
FDM (Fused Deposition Modeling): it is the most common process and involves heating and pushing a plastic filament through a nozzle, moving along the X axes, Y and Z to create the desired layer. The plastic material therefore melts with the previous layer and solidifies quickly.
SLA (Stereolithography): it is the older process which consists of exposing a photosensitive resin to an ultraviolet light source, and by UV-induced polymerization, in specific areas, it hardens only in the irradiated areas. The build plate gradually lowers into the vat of resin to build layer upon layer. In this case the most used plastic material is the resin in the liquid state.
SLS (Selective Laser Sintering): it is the most versatile process and consists of melting a special powder with a thin laser beam, that follows the contour of the model to be printed. In this 3D printing technology the most used materials are nylon and polyamide.
The 3D printing process also requires a 3D drawing software for the creation of the digital model of the object which is usually saved in a file with the extension STL.
Then with another specific software named SLICERS, the digital model will be sliced into thin horizontal layers commonly named “layer” Each layer can typically have a thickness between 0,1 e 0,3mm and for each of these srtati, the paths that the extrusion head of the 3D printer will have to execute will also be created.
The invention of 3D printing.
3D printing was developed by Charles W. Hull in 1983. Hull founded 3D Systems Corporation and introduced the first 3D printer, chiamata “stereolithography apparatus (SLA)”, which uses ultraviolet light curing technology to create three-dimensional objects. This invention thus marked the beginning of the great revolution of 3D printing.
In particular, la stampa 3D FDM (Fused Deposition Modeling) it was invented by Scott Crump in 1988. Crump founded Stratasys Ltd., a leading company in the 3D printing sector, and introduced the first FDM printer, called "Modeler". This technology uses filament deposition of molten material to create three-dimensional objects by depositing plastic material layer upon layer. FDM 3D printing has rapidly spread and has become one of the most popular and accessible techniques for producing three-dimensional objects.
3D printing has different applications in different industries, including designs, rapid prototyping, production of custom parts, medicine, electronics, architecture and jewelry, just to name a few examples.
This technology has the advantage of considerably reducing the costs of prototyping and small series production, it also allows the creation of complex and personalized objects, also reducing material waste. However, on this process there are still challenges in development, such as increasing the printing speed while maintaining the good quality of the details.
In short, 3D printing is an ever-evolving technology that is revolutionizing the way we create physical objects, offering creative possibilities and also the development of new unprecedented businesses.
3D printing in industry.
3D printing is revolutionizing the industry in many different ways. Thanks to its ability to create complex objects quickly and cheaply, 3D printing is used in many sectors of industry for the production of customized parts and components. For example, in the automotive sector, 3D printing is used to produce customized replacement parts for vehicles, reducing production costs and improving delivery times. In the aerospace industry, 3D printing is used to produce lightweight and strong aircraft parts, helping to reduce the weight of aircraft and improving fuel efficiency. Furthermore, 3D printing is also used in the medical industry for the production of customized prosthetics and anatomical models for surgical planning. In general, 3D printing is revolutionizing manufacturing in many sectors of industry and is expected to continue to do so in the future, helping to improve efficiency, the customization and sustainability of production.
