Design work related to the implementation of new aerospace elements requires the use of 3D-CAD modelling techniques and rapid prototyping, which makes it possible to significantly accelerate the deployment of new solutions. The article presents the possibility of using some methods of rapid prototyping to produce the research model of a wheel hub forming part of the landing gear. Incremental rapid prototyping methods - JS (Jetting System), SLA (Stereolithography), FDM (Fused Depositing Modelling) - have been characterized with regard to the technology of executing a hub model, the parameters of the manufacturing apparatus, and comparing basic technical data of materials used in the analyzed processes. One of the elements of the process of prototyping was to process data in other equipment for rapid prototyping. This process consisted of the following steps: defining the parameters of model building, determining the appropriate model settings in the workspace of manufacturing equipment, editing the supporting structure, verifying the subsequent layers through the simulation of model building process, generating output numerical procedures for manufacturing equipment. Manufactured prototypes have been evaluated of dimensional accuracy with the use coordinate measuring machine. Also measured the surface roughness. Conducted studies were the basis to determine the applicability of various methods of rapid prototyping in the process of research and manufacturing aircraft wheel hub.
