Application of Water-Based Magnetorheological Fluid in the Production of Stereoscopic Printing Grating

As one of the intelligent materials, Magnetorheological Fluid is dispersions composed of soft magnetic particles, carrier liquid and additives. The apparent yield strength of Magnetorheological Fluid can be changed significantly within milliseconds by the application of an external magnetic field. As the key elements of the three-dimensional imaging, the three-dimensional grating is a special material composed of cylindrical lens. Because water-based magnetorheological fluid has a unique magnetorheological effect, good rheological properties and environment-friendly performance, it is applied to the production of three-dimensional printing grating, through the change of the magnetorheological fluid to control the exact distribution of the soft magnetic particles, so as to achieve the desired accuracy, light transmittance and stability of printing raster, and finally present a ideal three-dimensional effect after laminating the grating and three-dimensional images.

In this study, a soft structure with its stiffness tunable by an external field is proposed. The proposed soft beam structure consists of a skin structure with channels filled with a magnetorheological fluid (MRF). Two specimens of the soft structure are fabricated by three-dimensional printing and fused deposition modeling. In the fabrication, a nozzle is used to obtain channels in the skin of the thermoplastic polyurethane, while another nozzle is used to fill MRF in the channels. The specimens are tested by using a universal tensile machine to evaluate the relationships between the load and deflection under two different conditions, without and with permanent magnets. It is empirically shown that the stiffness of the proposed soft structure can be altered by activating the magnetic field.

Ossifying fibroma (OF) is a rare, benign, fibro-osseous lesion of the jawbone characterised by replacement of the normal bone with fibrous tissue. The fibrous tissue shows varying amount of calcified structures resembling bone and/or cementum. The central variant of OF is rare, and shows predilection for mandible among the jawbone. Although it is classified as fibro-osseous lesion, it clinically behaves as a benign tumour and can grow to large size, causing bony swelling and facial asymmetry. This paper reports a case of large central OF of mandible in a 40-year-old male patient. The lesion was treated by segmental resection of mandible. Reconstruction of the surgical defect was done using avascular fibula bone graft. Role of three-dimensional printing of jaw and its benefits in surgical planning and reconstruction are also highlighted.
