![]() Price cutting and technical development of 3D printing systems: Additive Manufacturing Systems became more interesting and affordable due to a higher demand, advanced technique and further development. The inhabitation level and reserve in connection with computer therefor increased drastically. Some people even see another industrial revolution as well as decentralising and/or democratisation of products.īetter Access and vaster understanding for computer systems: Due to continuous computerisation over the last decades, computer systems and as a consequence thereof (3D)software experienced a massive increase in users. Inspired by Maker-, DIY- and Open Source-Philosopies and fascinated by Star Trek’s “Replicator”, this technology became increasingly popular. This can be explained by the following reasons:Įxpiry of patent on Fused Deposition Modelling (FDM): A few years ago the patent on the priting method FMD (former FFF) expired and allowed for the open source 3D printer RepRap to emerge.įascination Technology: The pure imagination of printing ready to use products at home is fascination for many people and boosts the current trend. 3D Printing (3DP) actually describes just one of the many processes, however it is used commonly as a synonym for additive manufacturing.Īlthough technologies have been existing for a long time, Rapid Manufacturing systems have been experiencing a real boom during the last few years. The narrowing line between prototype and end-product coined the terms Rapid Manufacturing and Direct manufacturing.ĭuring the last years mainly the non-technical term “3D Printing” has evolved in everyday language, being used for all additive manufacturing methods. Some Processes allowed not only the production of objects serving as prototypes but also as a final product. However, over the years quality has significantly and gradually improved through advanced machines and material as well as with the aid of high-performance computers. Being only used as illustrative models, requirements in regard to durability, quality and stability have not been particularly demanding in the beginning. Formula One) employing Rapid Prototyping. Initially theses methods were used to create inexpensive prototypes for product development (e.g. This method was commercialised only years later and further processes like 3DP and FDM evolved and were patented. As a result money and time can be saved during product development.Īs early as 1984 the first additive method called Stereolithografie was developed by Chuck Hull (founder of 3D Systems). Instead of manual model making by using cardboard and foam or modelling design drafts from clay, templates for manufacturing are created using computers. Whereas models and prototypes were once manually built, nowadays automated manufacturing processes are being employed. This term describes all other processes which cannot be clearly categorised or consist of several techniques.įrom Rapid Prototyping to Rapid Manufacturing This is done by either folding, pressing or moulding. a CAD file) which is translated into a machine readable code serves as a template in this process.īesides additive and subtractive processes, further following two methods are being distinguished:Īn object is being formed by applying mechanical or thermal forces. CNC machines) and other processes like electrical discharge machining additive manufacturing deals with adding, applying and depositing material. Fields of application for AM-technologies (partly experimental):Īdditive Manufacturing was described as “ process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies, such as traditional machining” by ASTM International (2012).Ĭontrary to subtractive fabrication, where raw material is being removed by milling, machining, drilling (e.g. ![]() From Rapid Prototyping to Rapid Manufacturing.Additive Manufacturing (AM), Generative Manufacturing.
