This paper presents an experimental experience with manufacturing of functional parts of the mechanical system using rapid prototyping. We have designed two different functional parts of experimental instrument for manufacturing by two kinds of rapid Prototyping technology. We summarize a review of dimensional and geometrical differences between CaD data and manufactured parts. We determined that dimensions of the smallest details successfully manufactured using rapid prototyping technology are limited with surface tension of rapid prototyping material in its liquid state. We performed few functional and geometrical tests on fabricated parts, which show full functionality of manufactured parts in designed optomechanical measurement instrument. and Článek prezentuje výrobu dvou geometricky komplikovaných součástí určených pro navrhované laboratorní optickomechanické zařízení. Pro výrobu součástí byly testovány celkem dvě různé technologie Rapid Prototypingu a tři různé typy materiálů. Byly provedeny testy geometrických odchylek mezi daty CAD modelů a vyrobených součástí a také funkční testy vytvořených součástí přímo v realizovaném zařízení. Oba typy součástí se ukázaly po nezbytných úpravách jako plně funkční a výrazně zjednodušující konstrukční řešení realizovaného zařízení.
Bruno Latour’s article challenges the preconceived notions with which the scholars have approached the Great Divide between prescientific and scientific cultures. In order to account for the immense effects of science and technology without assuming a single grand cause for them, he suggests to focus on many, small unexpected and practical sets of skills to produce images, and to read and write about them. However, only those changes that intervene favorably in the agonistic situation in science should be considered. Crucial in this respect is the emergence of numerous “immutable mobiles” - easily transported, accumulated, combined, yet lasting objects - which made possible the mobilization of new scientific inscriptions and of new ways of looking at and presenting them. They help to constitute an optically consistent visual culture with such technologies as printing press. Their combination on the surface of paper and subsequent mobilization of allies can usher in bureaucratic mode of domination over the world and people in the scientific field. The effects of science and technology thus become a question of a shift in power relations enabled by the manipulation of inscriptions., Bruno, Latour., and Obsahuje bibliografii
