The paper presents the studies on the reliability of printer Rebuild v3 during the implementation of the order of the Institute of Construction Technology. The object of the study was printing out of three miniature houses for fire tests and evaluation of burning ability of printouts made from the concrete. All the houses were printed during one session, lasting for 27h. Apart from the process of producing the objects, it was also possible to check the reliability and behaviour of the printer in so long and non-interrupted process.

Artykuł przedstawia badania niezawodności drukarki REbuild v3 w trakcie realizacji zlecenia dla Instytutu Techniki Budowlanej. Przedmiotem badania było wydrukowanie trzech miniaturowych domków do testów ogniowych i oceny palności wydruków z betonu. Wszystkie domki zostały wydrukowane podczas jednej sesji trwającej 27 godzin. Poza samym procesem wykonania obiektów, udało się sprawdzić niezawodność i zachowanie drukarki w tak długim i nieprzerywanym procesie.

The article describes two versions of a gripper's fingers that utilize compliant revolute kinematic pairs in their operation. The goal in designing the gripper was to create a universal structure that allows for easy adjustment of torsional stiffness and maximum rotation angle as needed. Two compliant revolute joints were proposed and applied in the creation of two versions of the gripper’s fingers. In both joints, one geometric parameter was selected for variation. Finite element analysis was conducted to calculate the statics within the parameter range. Based on the calculations, stiffness charts were created as a function of parameter values. Subsequently, using 3D printing technology in resin, two gripper fingers were produced. Experimental tests were conducted on these fingers to assess their torsional stiffness. The computational and experimental results were compared. The designed fingers are best suited for pneumatic grippers. When using them, complex force control can be eliminated because the gripping force increases gradually in accordance with the compliance of the gripper, rather than abruptly. The fingers also exhibit different stiffness characteristics depending on the direction of the grip - outward or inward.
