The article deals with the modelling of gyroid structure as a base of lightweight component produced by additive technology. Gyroid is one type of so called porous structure that can give to the product extraordinary combination properties such are high strength, stiffness along with low weight and good absorption of energy. This is a reason, why they are widespread not only in mechanical, aerospace or automotive industries, but also in biomedicine. In mechanical engineering, it is possible to produce the gyroids by some of modern additive technologies, because the complex surface of this type it is not possible to produce in another way. The basement of product, which is made by some of additive technologies, is virtual 3D model, so it is necessary to know how to generate it. Three approaches to the modelling have been presented in the article, including the description of the advantages or disadvantages of individual method. Well prepared model can be used not only for gyroid structure manufacturing, but also for simulation its behavior in real practice.
