Understanding the value of an entrepreneur and their importance in society is one of the main factors we explain in this work. We have created a business plan to demonstrate its viability, but as well as demonstrating it, we are also presenting the business step by step, methods of organisation, planning and control so that the best actions are always taken with as few mistakes as possible. The business plan consists of setting up a company that will commercialise products produced using 3D printing, a kind of 3D printing company, where prototypes and parts will be developed for other companies, thus saving time and money, with the aim of providing customers with ease and savings in their business. It's a market that has yet to be explored, but it's already being used in research at universities. The commercialisation of 3D printing is an innovative venture and fits in perfectly with contemporary market needs, so the studies carried out show that it is a viable business.
