The knowledge of the mechanical properties of the material used is a necessary prerequisite for the quality design of any structural unit. It applies to components manufactured using Rapid Prototyping technology (hereinafter only RP) multiple times, because it is not enough to only know the mechanical properties of a material from which the components are printed. Other factors affect the component printing, such as the orientation of the printed component, the selection of the component's internal structure, possibility of connection with other materials, etc. The article follows from the previous research of the experimental determination of the bend strength of parts printed by RP technology from polycarbonate, which focuses on bend-testing of samples printed with various internal structures. This article expands on the original research by experimental determination of the bend strength of printed components, which form a unit with another material. The obtained information can be utilised in the design of components manufactured with RP technology using professional printers.

“…The design of the internal structure was executed in Creo 2.0 software [5], where the solid material in the thickness matching multiples of the contour width was clearly defined and subsequent setting of the number of contours in the Insight software for printing achieved the required printing trajectory to obtain higher strength in the direction of the acting tensile forces. The internal structure of the samples was designed with respect to the technological possibilities and findings gained from research into RP printing technology precision [6,7]. The printing parameters of individual samples are shown in Tab.…”

Recently, the Rapid Prototyping technology (RP hereafter) has been increasingly used for a final product, which requires detailed knowledge of designing parts made by the RP technology. In order to apply parts made by the RP technology in robotics, and design in general, in a wider range, one of the most important material parameters is their bend strength. The paper describes an experimental determination of bend strength in parts printed on a 3D printer. The parts were made of polycarbonate. The tests were carried out in parts with various types of internal structure. The achieved results can be implemented when designing parts made by 3D printing provided that professional printers are used.

“…3) from two materials with different internal printing structures. The samples were designed taking into account technological requirements and findings obtained from examination of RP printing precision [6].…”

For the Rapid Prototyping ("RP") technology to be usable in the design of equipment (even if only a prototype is to be designed), the material properties of the component so obtained must be known as early as the design stage. Among important properties of materials is their tensile strength. This paper describes tensile tests of samples manufactured by the RP technology. All of the samples had identical dimensions but differed in the internal arrangement of the structures and in the basic orientation of the print. The results are compared to those obtained in the tensile test of polycarbonate manufactured by the conventional process.I.
