“…Additional stages of the same size were fabricated using a 3D-printer to compare the maximum stress and first natural frequency of the three cases. The PZT actuators used has a travel length of 60 µ m, a resolution of 1.2 nm and a stiffness of 15 N/ µ m. The maximum stress and maximum rotation are expressed as equations (5) and (6), respectively (Jung and Kim, 2014): …”

“…PZT actuators have been widely used as fine-positioning-devices because of their advantages such as high positioning resolution, high generative force, high response speed and easy miniaturization (Fantoni et al , 2018; Wang et al , 2018; Chen et al , 2019; Jian et al , 2019). Therefore, many studies have been conducted on the design and manufacture of precision-positioning stages using flexure hinges and PZT actuators (Park et al , 2007; Jung and Kim, 2014; Clark et al , 2015; Qin et al , 2019; Tian et al , 2019; Zhang et al , 2020).…”

“…This rapid-prototyping process is advantageous for manufacturing complex shapes that cannot be easily produced by using conventional methods such as CNC lathes, milling machines or wire-cut electrical discharge machines, especially in manufacturing fields for precision engineering. It also has the merits of enabling compact designs at a lower cost and reduced weight and assigning different material properties locally (Jung and Kim, 2014; Shemelya et al , 2014; Laszczak et al , 2015; Christ et al , 2017; Li et al , 2018; Liu et al , 2018; Jayanth and Senthil, 2019; Liu et al , 2019).…”

Purpose This paper aims to propose a method for manufacturing multi-material monolithic structures with flexible materials to construct the elastic body by using a dual-nozzle three-dimensional printer to develop a piezoelectric (PZT)-driven micropositioning stage with three degrees of freedom (3-DOF) and flexure hinges. Design/methodology/approach Polylactic acid (PLA) and nylon were used for the lever structure’s frame and flexure hinge, respectively. Additionally, the stage consisted of three PZT actuators for fine movement in the nanometer scale in 3-DOF (x, y and θ-directions). For the design of the stage, the kinematic analysis model and the finite element method (FEM) analysis was undertaken for comparing between PLA with nylon (multi-material), PLA (single material) and aluminum (conventional-material). In addition, two verification experiments were implemented for the fabricated prototype stage. First, to evaluate various assessments (lever ratio, hysteresis, coupling error and resolution), a measurement is carried out using the three capacitive sensors. Then, a two-camera-vision measurement experiment was performed to verify the displacement and lever ratio over the full-scale working range of the fabricated positioning stage, and the results from the experimentation and the FEM analysis were compared. Findings The authors confirmed enhancements in the properties of the lever structure frame, which requires stiffness and of the hinge, which requires flexibility for elastic deformation. Comparing FEM analysis and experimental results, although the performance as shown by experimental results was lower: the maximum difference being 3.4% within the end-point working range; this difference was sufficient to be a plausible alternative for the aluminum-based stage. Originality/value Multi-material monolithic-structure fabrication has an effective advantage in improving the performance of the stage, by using a combination of materials capable of reinforcing the desired characteristics in the necessary parts. It was verified that the fabricated stage can substitute the aluminum-based stage and can achieve a higher performance than single-material stages. Thus, precise-positioning stages can be manufactured in many kinds of structures with various properties and contribute to weight reduction and low costs for application equipment.

“…The traditional monolithic precision positioning stages are generally fabricated by aluminum alloy material using electrical discharging machining (EDM) method (Jung and Kim, 2014), (Qin et al , 2013). This kind of monolithic structure has the advantage of no assembling errors, however, disadvantages are time-cost manufacturing process and the failure components cannot be replaced.…”

Purpose Generally, the motion range of the micro scale operation is within several hundreds of microns, and the conventional joints cannot satisfy the requirements due to manufacturing and assembling errors, hysteresis and backlash in the joints. The paper aims to discuss these issues. Design/methodology/approach The following issues should be considered: a micromanipulation stage should be designed using a small-dimensional scale driven by the small size of piezoelectric actuator and the components can be replaced due to fatigue failure caused by repeated cyclic loading. This paper proposes a modular design of a flexure-based 2-DOF precision stage made using aluminum (T6-7075) material and Acrylonitrile Butadiene Styrene plastic material. The piezoelectric actuator is adopted to drive the stage for the fast response and large output force. To compensate the stroke of piezoelectric actuator, a bridge-type amplifier is designed with optimized structure. Findings The simulation results validate the advantages of modular positioning stage fabricated by two different materials. Research limitations/implications The stage can be used in micro scale precision’s applications. If it will be used in nanoscale precision, then some sensors in nanoscale of measurement should be used. Practical implications The designed stage can be used in biomedical engineering, such as cell injection testing, etc. Social implications The designed stage will be used in micro/nanoengineering field, such as micro/nanomanufacturing or assembly, manipulation of cell, etc., which will push forward high technology to a higher level. Originality/value Two kinds of materials have been selected to make the positioning stage, which are seldomly found in literature on compliant mechanism field. A modular design concept is proposed for the positioning stage design.

Article history:This paper summarizes the results of an investigation into the environmental factors that have an indirect impact on parts quality, as well as those process variables and modeling information that have a direct impact. The effects of strength, surface hardness, roughness, and accuracy of shape, that is, qualities that users generally need to know, were evaluated with laminating direction experimentally. The 3D printing methods used in this experiment were fused deposition modeling (FDM), stereolithography apparatus (SLA), selective laser sintering (SLS), 3D printing (3DP) and laminated object manufacturing (LOM). The goal was to achieve a high standard of quality control and product quality by optimizing the fabrication process.
