Abstract
EN Stereolithography (SLA), Digital Light Processing (DLP), and Fused Deposition Modeling (FDM) technologies have evolved a lot in the last decade, making 3D printers more and more accurate, faster, and at more and more affordable prices. The precision of the parts obtained through these technologies has reached the order of microns, and the materials used by these technologies are increasingly versatile, from classic PLA, ABS, PEEK plastics, reinforced plastics with metal particles or wood particles, respectively different types of photopolymerisable resins. The software used by SLA, DLP, and FDM technologies is numerous and very sophisticated because it allows the manufacture with very great precision of 3D prototypes, identical to the designed 3D model, through modern additive manufacturing techniques. These 3D printers are used to make three-dimensional parts that can be used in different industries such as: aeronautical and aerospace, automotive, tooling, electronics, robotics, medicine, architecture, and design. The quality and mechanical strength of the prototypes obtained using 3D printers are very good, these technologies permit to realize of very fine lattice structures of the parts. In this article were realized different SEM, EDS and Mapping analysis for simple and composite photopolymerisable resins, and PEEK materials to determine the morphological structure, the qualitative and quantitative chemical composition, and the distribution of chemical compounds in the structure. The objective of the work consists of the design and 3D printing of a functional prototype in the architecture field to determine the processing precision and to compare the optimal processing variant depending on the type of additive manufacturing process, material, and desired precision.
