3D printing (3DP) has transformed engineering, manufacturing, and the use of advanced materials due to its ability to produce objects from a variety of materials, ranging from soft polymers to rigid ceramics. 3DP offers the advantage of being able to print at a variety of lengths scales; from a few micrometers to many meters. 3DP has the unique ability to produce customized small lots, efficiently. Yet, one crucial industry that has not been able to adequately explore its potential is textile manufacturing. The research in 3DP of textiles has lagged behind other areas primarily due to the difficulty in obtaining some of the unique characteristics of strength, flexibility, etc., of textiles, utilizing a fundamentally different manufacturing technology. Textiles are their own class of materials due to the specific structural developments that occur during the various stages of textile manufacturing: from fiber extrusion to assembly of the fibers to fabrics. Here, the current 3DP technologies are reviewed with emphasis on soft and anisotropic structures, as well as the efforts toward 3DP of textiles. Finally, a potential pathway to 3DP of textiles, dubbed as printing with fibers to create textile structures is proposed for further exploration.

The article reviews the literature focused on investigating the adhesion strength between the 3D-printed polymers and the textile substrates, and its dependence on different factors related to materials, printing parameters, and fabrics type and structure. 3D printing (3DP) onto textiles is a domain in expansion as it allows developing products with new functionalities by gathering the advantages of design freedom, tailor-fit, comfort, variety, and mass customization provided by both the textiles and the additive manufacturing technology. In this context, it becomes important to document and understand how the adherence of different 3D-printed molten polymer to diverse textiles substrates can be improved for obtaining products more resistant to specific conditions, such as washing, wear, or ironing.

Additive manufacturing (AM), also known as three-dimensional printing (3DP), has been widely applied to various fields and industries, including automotive, healthcare, and rapid prototyping. This study evaluates the effects of 3DP on textile properties. The usability of a textile and its durability are determined by its strength, washability, colorfastness to light, and abrasion resistance, among other traits, which may be impacted by the application of 3DP on the fabric's surface.

3D printing (3DP) technology for tissue engineering applications has been extensively studied for materials and processes. However, clinical application to the vascular system was limited owing to mechanical inconsistency and toxicity. Here, we characterized 3D templated artificial vascular grafts (3D grafts), which were fabricated by an integrative method involving 3DP, dip coating, and salt leaching method.

This study purposed to develop conductivity 3D printed (3DP) fingertips and confirm their potential for use in a pressure sensor. Index fingertips were 3D printed using thermoplastic polyurethane filament with three types of infill patterns (Zigzag (ZG), Triangles (TR), Honeycomb (HN)) and densities (20%, 50%, 80%). Hence, the 3DP index fingertip was dip-coated with 8 wt% graphene/waterborne polyurethane composite solution.
