Modification of a new printable material for tribological applications

Original language description

The result is poster presentation on 10th International Conference on Chemical Technology ICCT 2023. Nowadays, 3D printing technology is so advanced that it finds application in almost every branch of human activity. One of the basic technologies of 3D printing is FDM (fused deposition modeling)/FFF (fused filament fabrication). This method is used for prototyping or small series production of plastic parts. In this industry, the additive FDM technology has enormous potential, because the time to make a prototype is reduced from a few weeks to a few hours, there is a minimum of waste, and in addition, the price of the resulting prototype is only several units to tens of EUR. One of the factors limiting the widespread use of this technology in the area of design of tribological structural parts is the insufficient supply of materials with satisfactory tribological properties and the frequent necessity of using special printers with a purchase price of several tens of thousands EUR. In this work, a new composite material was developed, which can be processed on almost all common 3D FDM/FFF printers with a purchase price of several hundred EUR. The composite material was produced by modifying a material based on POM (poly(oxymethylene)) with PTFE (poly(tetrafluoroethylene)). This material is the result of previous research activity. Two fillers were used for the modification – carbon and basalt fibers. Two mixtures were prepared by compounding the fillers with the base material. Filaments were prepared from the mixtures, which were checked for homogeneity. This was followed by determination of parameters for 3D printing, adjustment of the printing pad and verification of printability. The final step was the printing of test specimens to verify the mechanical and tribological properties.
