W niniejszym artykule przedstawiono pierwszy etap prac, który dotyczył zrywania próbek wykonanych w różnych ustawieniach wybranymi metodami RP: FDM (Fused Deposition Modeling) z czystego ABS, LOM (Laminated Object Manufacturing) z foli PCV, PJM (PolyJet Modeling) z żywicy akrylowej, 3DP (3D Printing) z proszku na bazie gipsu infiltrowanego żywicą epoksydową. Celem pracy jest zbadanie wpływu parametrów technologicznych metod RP na parametry wytrzymałościowe wytwarzanego obiektu.

In the paper, the author provides a proposal of a quick prototyping environment for algorithms controlling homogenous, autonomous mobile robots. The solution proposed enables monitoring of the operation of a group of mobile robots consisting of the recording of motion parameters and signals from distance detectors as well as of controlling the drive units. Furthermore, the solution is flexible, enabling work with various numbers of robots as well as modification of their settings, and conforms to the real time system requirements assumed. In the course of the development process, AmigoBot mobile robots manufactured by ActiveMedia Robotics were used. The control and measuring environment proposed has been verified based on the sample behavioural task of "running in the middle of a free space".

The research focused on the production of prototype castings, which is mapped out starting from the drawing documentation up to the production of the casting itself. The FDM method was applied for the production of the 3D pattern. Its main objective was to find out what dimensional changes happened during individual production stages, starting from the 3D pattern printing through a silicon mould production, wax patterns casting, making shells, melting out wax from shells and drying, up to the production of the final casting itself. Five measurements of determined dimensions were made during the production, which were processed and evaluated mathematically. A determination of shrinkage and a proposal of measures to maintain the dimensional stability of the final casting so as to meet requirements specified by a customer were the results.
