Plastography, also known as plastic printing or additive manufacturing, is a manufacturing technique that consists of creating three-dimensional objects by layering successive layers of material. It involves the use of computer-aided design (CAD) software to design the object, followed by the use of a specialized printer that deposits thin layers of molten plastic material on top of each other to form the final shape.
The process of plastography begins with the creation of a digital model of the desired object using CAD software. This digital model is then sliced into multiple layers, which are subsequently sent to the plastography printer. The printer reads each layer and deposits a liquid plastic material, usually in the form of a filament, onto a build platform. The material is hardened or cured using various techniques, such as cooling or exposure to ultraviolet light, to solidify each layer.
Plastography has gained significant popularity due to its versatility, cost-effectiveness, and ability to create complex geometries that would be challenging or impossible to manufacture using traditional methods. It finds applications in a wide range of industries, including aerospace, automotive, healthcare, architecture, and consumer goods.
The use of plastography enables rapid prototyping, customization, and the production of small to medium-sized batches of components with reduced waste and lead times. Additionally, it allows for the integration of functional features, such as cavities, hinges, and internal structures, directly into the object during the printing process. However, it is important to note that plastography is limited by material properties, as not all plastics are suitable for the process, and the final objects may exhibit lower strength or durability compared to conventionally manufactured parts.
