Press fit design : force and torque testing of steel dowel pins in brass and nylon samples
… conducted to determine the accuracy of current press fit theory when applied to press fit design. Brass and nylon hex samples were press fitted with hardened steel dowel pins. Press fit force and torque required to induce slipping were measured experimentally. Sample dimensions and material …

Additive assembly of digital materials
… thesis develops the use of additive assembly of press-fit digital materials as a new rapid-prototyping process. Digital materials consist of a finite set of parts that have discrete connections and occupy discrete space. Part geometries were designed and fabricated at different scales from …

Optical Fiber Microstructures for Self-Contained Whispering Gallery Mode Excitation
… the fabrication and function of three new "press fit" spherical resonators. These etched fiber micro-devices were developed to meet the demand for a robust, self-integrated means of coupling light between an optical fiber and WGMs in a microsphere resonator. The etching processes have been …

Standzeitverkürzende Patientencharakteristika und Protheseneigenschaften von aseptisch gelockerten Hüftendoprothesen
… regard to the acetabular components cementless Press-Fit Cups yielded the best results with 12 years survival time, followed by cemented PE-Cups (11years) and Screwing Rings (10 years). With regard to revisions primary revisions had an average survival time for the femoral components of 12 years …

Additive Manufacturing for Robust and Affordable Medical Devices
… the lower cost would allow more people to benefit from inexpensive diagnosis. Also, the GMO biosensors would be contained with a press-fit, ensuring that the living biosensors are unable to escape into the environment without user input. In addition, 3D-printing can also be applied to reduce …

Primary stability in cementless total hip replacement: measurement techniques and aided-surgery
… meant to help the surgeon to decide how much to press-fit the implant. It is essentially made of a torsional load cell, able to measure the extent of torque applied by the surgeon to test primary stability, an angular sensor that measure the relative angular displacement between stem and femur, a …
