Brief History of Additive Manufacture and the Effect of Patents

In the present article, the author presents a study of the history of patents, as well as the effect of this on the progress of additive manufacturing. This brief history of additive manufacturing, aims to be a mandatory reading for all that researcher, scientist or company manager, who wants to be able to situate the current moment of additive manufacturing, and be able to judge the effect that patents have had on the development of this technology. Therefore, it should be noted, that the expiration of the patents that protected some Additive Manufacturing technologies, thus allowing the entry into the market of universities and small companies manufacturing and marketing personal printers economically very affordable

Modelling of Information for Additive Manufacture (AP242) and Comparative with Other Existing Models

With the advent of new technologies, there has been a revolution in recent decades that is not alien to companies. Nowadays, the organization of the company is subject to a series of information and/or qualities that are convenient to organize. In order that the information of a company can be used by other collaborating companies, some standards that allow communication have been created. The ISO 10303 standard, better known as STEP, is the international standard that is fulfilling this objective of standardizing the methods that allow what is called "interoperability". Very recently, different solutions are being articulated to those proposed ones in this study, aimed at providing solutions to the same problems, such as using the model based on STEP - NC. The purpose of this research is to develop a proposal that incorporates the AP242 standard (ISO 10303) in the information model for a manufacturing technique that is growing at great speed, known as "Additive Manufacturing"; for this purpose, the feasible project methodology is used, in addition to making a comparison with other existing models
