Textile Fabric

Today, additive manufacturing, also called three-dimensional printing, is used for producing prototypes as well as other products for various industrial sectors. Although this technology is already well established in the automotive, aviation and space travel, building, dental and medical sectors, its integration in the textile and ready-made industry is still in progress. At present, there is a lack of specific application scenarios for the combination of three-dimensional printing and textile materials, apart from fashion and shoe design. Hence, this article presents a digital computer-aided engineering–supported process to manufacture customized orthopaedic devices by three-dimensional printing directly onto a textile fabric. State-of-the-art fabrication methods for orthoses are typically labour intensive. The combination of three-dimensional scanning, computer-aided design modelling and three-dimensional printing onto textile materials open up new possibilities for producing custom-made products. After three-dimensional scanning of a patient’s individual body shape, the surface is prepared for constructing the textile pattern cuts by reverse engineering. The transformation of the designed three-dimensional patterns into two-dimensional is software supported. Additional positioning lines in accordance with specific body measurements are transferred onto the two-dimensional pattern cuts, which are then used as the basis for the design of the three-dimensional printed functional elements. Subsequently, the design is saved in STL (Standard Triangulation/Tessellation Language) file format, prepared by slicing and directly printed onto textile pattern cuts by means of fused deposition modelling. The last manufacturing step involves the assembly of the textile fabric. The proposed process is demonstrated by an example application scenario, thus proving its potential for industrial use in the textile and ready-made industry.

There is a large somatosensory gap between the three-dimensional (3D) printing of clothing and traditional garments due to the limitations (e.g., air permeability and skin-friendliness) of the printing materials. For this reason, the application of traditional textile materials in 3D printing has become a hot topic in the field of 3D printed clothing. Based on the above, this work prepared four kinds of cotton-containing composite solutions and then impregnated thermoplastic polyurethane core yarns in these solutions to obtain four types of 3D printed cotton-containing composite core yarns (3Dp-C-CYs). Afterward, based on the two-dimensional (2D) braiding method, four kinds of cotton-containing 3D printing wires used for fused deposition molding technology were prepared by wrapping low-melting polyester filaments around the different 3Dp-C-CYs. After comparing the printing performance of the four cotton-containing 3D printing wires, the wire containing cotton powders had the best comprehensive performance and was selected to print the cotton-containing 3D printed fabrics. The results showed that the cotton-containing 3D printed fabric has good flatness and contains a large number of cotton powders; in addition, compared with the traditional polylactic acid and acrylonitrile butadiene styrene copolymer 3D printed fabrics, the 3D printed fabric made up of cotton-containing 3D printing wire can provide a closer wearing experience to that of cotton fabric. The 3D printing wire produced by the 2D braiding method offers a new idea for applying traditional textile materials in 3D printing, showing great application potentials in the field of 3D printing of clothing.

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.

AbstractThe molybdenum disulfide (MoS2)-based photodetectors are facing two challenges: the insensitivity to polarized light and the low photoresponsivity. Herein, three-dimensional (3D) field-effect transistors (FETs) based on monolayer MoS2 were fabricated by applying a self–rolled-up technique. The unique microtubular structure makes 3D MoS2 FETs become polarization sensitive. Moreover, the microtubular structure not only offers a natural resonant microcavity to enhance the optical field inside but also increases the light-MoS2 interaction area, resulting in a higher photoresponsivity. Photoresponsivities as high as 23.8 and 2.9 A/W at 395 and 660 nm, respectively, and a comparable polarization ratio of 1.64 were obtained. The fabrication technique of the 3D MoS2 FET could be transferred to other two-dimensional materials, which is very promising for high-performance polarization-sensitive optical and optoelectronic applications.
