Polyphenylene sulfide (PPS) is a high-performance, low-cost special engineering polymer. The mechanical properties of three-dimensionally (3D) printed PPS samples are affected by the mass melt extruded filament and printing pattern in inner layer. present study demonstrates effects extrusion alignment parameters on tensile, bending, impact strengths 3D samples. results indicate that increasing parameters, tensile bending can be improved internal voids between adjacent filaments eliminated....
In this paper, a novel piezo-driven rotary actuator with the changeable clamping radius is developed based on inchworm principle. This mainly utilizes three piezoelectric actuators, flexible gripper, block, and rotor to achieve large stroke rotation high resolution. The design process of gripper consisting driving unit described. Lever-type mechanisms were used amplify micro displacements. amplifying factor parasitic displacement lever-type mechanism in was analyzed theoretically...
This paper presents a novel piezo-driven rotary actuator based on the parasitic motion principle. Output performances of were tested and discussed. Experiment results indicate that using only one piezoelectric simple sawtooth wave control, reaches rotation velocity about 20 097 μrad/s when driving voltage is 100 V frequency 90 Hz. The can rotate stably with minimum resolution 0.7 μrad. verifies feasibility principle for applications actuators, providing new design ideas precision actuators.
Abstract Fused filament fabrication (FFF) printing had the advantages of simple structure, low cost, and process. As requirement for high‐performance special engineering plastics was increasing progressively, FFF 3D technology with Polyether‐ether‐ketone (PEEK) as typical material also developing rapidly. It worth noting that there were unavoidable defects caused by comprehensive factors forming conditions equipment. Therefore, main aim this study to investigate most reasonable composite...
Polyetheretherketone (PEEK), a high-performance special engineering plastic, has gradually been used in bone substitutes due to its wear resistance, acid and alkali non-toxicity, radiolucency, modulus close that of human bone. However, stable biphenyl structure determines strong biological inertness, thus artificial interventions are required improve the activity fabricated PEEK parts for better clinical applications. This study developed novel strategy grafting bioactive glass (BAG) onto...
