FDM technology printing methods

3D printing technologies were developed almost 30 years ago and one of their main features is that instead of removing 3D printing adds material layer by layer and the elements are created directly from CAD models. This type of technology offers an advantageous ability to produce components that are complex in shape and material, which cannot by produce by the traditional methods. Intensive research has led to significant advances in technology in recent years in the development and commercialization of new innovative 3D printing processes by modeling molten deposition (FDM), including composite printing. This paper outlines the main methods for creating polymer composite structures using FDM technology. Thanks to the constantly increasing quality of the final product produce by the am machine, there is a much greater connection and appearance between it and the prototype. Many components are already manufactured directly in these machines, so it is not correct to label them as prototypes.
