Sažetak
Compliant mechanisms are often used in micro and nano positioning as they can provide highly precise linear and rotational motions. Traditionally used manufacturing methods for production of compliant mechanisms are machining, stamping, as well as laser, water and EDM cutting. Stamping and cutting technologies are most commonly used but they are generally limited to two-dimensional geometry designs. More complex mechanisms can theoretically be produced using multi-axis machining, but deformation of the stock during thin wall machining creates problems in production and limits accuracy. In contrast to traditionally used technologies, additive manufacturing allows simple production of the complex geometries. This does not only allow production of currently unfeasible geometries but also speed up the design process.Compliant mechanisms for scales manipulation were designed with required displacement ranges as main objectives and additive manufacturing as production technology. Mechanisms displacements were measured with Mahr Millimar P2004 inductive probe. In horizontal direction displacement of 338, 7 µm was achieved and in vertical displacement total displacement of 105, 2 µm. Through whole range of motion, displacement resolution of under 100 nm was achieved. The results confirm feasibility of using additive manufacturing for production of complex alignment mechanisms in field of metrology.
