This paper presents the manufacturing processes using additive technologies, various types of materials used in manufacturing with additive technologies (3D and 4D printing). The advantages and disadvantages of individual manufacturing methods and smart materials that occupy the present day are mentioned. The historical development of 4D printers is discussed, answering how and why they were created, and why 4D printing is considered the beginning of a new industrial revolution. 4D printing is environmentally friendly, which is extremely important in today's time. However, along with all the advantages it brings, it also presents numerous potential dangers and problems. The aim of this paper is to present the benefits of additive technologies and 4D printers to the reader in the simplest and most understandable way possible. Of course, the disadvantages of these technologies are also mentioned. Additionally, the types of materials used and the manufacturing process using additive technology are outlined. Finally, the author provides their conclusion on the paper
