3D printing is used to produce individual objects or to print on different substrates to produce multi-component products. In the textile industry, we encounter various 3D printing technologies in fashion design, functional apparel manufacturing (protective, military, sports, etc.), including wearable electronics, where textile material is functionalized. 3D printing enables the personalization of the product, which in the apparel industry can be transformed into the production of clothing or parts of clothing or custom accessories. Additive technology allows a more rational use of the material than traditional technologies. In the textile industry we meet different uses of it, one is the printing of flexible structures based on rigid materials, another is the printing with flexible materials and the third is the printing directly on textile substrate. All rigid, hard and soft or flexible materials can be integrated into the final design using 3D printing directly on the textile substrate. We speak of so-called multi-material objects and systems, which have many advantages, mainly in the increasing customization and functionalization of textiles or clothing. The article gives a broader overview of 3D printing on textiles and focuses mainly on the influence of different parameters of printing and woven fabric properties on the adhesion of 3D printed objects on the textile substrate. In our research we investigated the influence of twill weave and its derivate as well as different weft densities of the woven fabric on the adhesion of printed objects on textile substrate. Therefore, five samples of twill polyester/cotton fabrics were woven and their physical properties measured for this research. 3D objects were printed on textile substrates using the extrusion based additive manufacturing technique with polylactic acid (PLA) filament. Preliminary tests were carried out to define printing parameters and different methods of attaching the fabric to a printing bed were tested. T - Peel adhesion tests were performed on the Instron dynamometer to measure the adhesion between 3D printed objects and textile substrates.

Abstract Although direct deposition of polymeric materials onto textiles through 3D printing is a great technique used more and more to develop smart textiles, one of the main challenges is to demonstrate equal or better mechanical resistance, durability and comfort than those of the textile substrates before deposition process. This article focuses on studying the impact of the textile properties and printing platform temperature on the tensile and deformations of non-conductive and conductive poly lactic acid (PLA) filaments deposited onto polyethylene terephthalate (PET) textiles through 3D printing process and optimizing them using theoretical and statistical models. The results demonstrate that the deposition process affects the tensile properties of the printed textile in comparison with the ones of the textiles. The stress and strain at rupture of the first 3D printed PLA layer deposited onto PET textile material reveal to be a combination of those of the printed layer and the PET fabric due to the lower flexibility and diffusion of the polymeric printed track through the textile fabric leading to a weak adhesion at the polymer/textile interface. Besides, printing platform temperature and textile properties influence the tensile and deformation properties of the 3D printed PLA on PET textile significantly. Both, the washing process and the incorporation of conductive fillers into the PLA do not affect the tensile properties of the extruded polymeric materials. The elastic, total and permanent deformations of the 3D-printed PLA on PET fabrics are lower than the ones of the fabric before polymer deposition which demonstrates a better dimensional stability, higher stiffness and lower flexibility of these materials.

The technology of additive manufacturing results in 3D printing of conductive traces in radio frequency circuits. This creates a plethora of possibilities in realizing flexible and wearable electronics. While the prototypes of microstrip transmission lines and antennas have been recently reported, there is now a need of Electromagnetic Compatibility based study of such 3D printed conductive traces. This paper presents a comparative study on the near end and far end unintentional crosstalk components between a pair of microstrip transmission lines made of Copper in the presence of a 3D printed conductive trace made of a commercially available conductive filament, Electrifi. Any physical contact with the 3D printed trace has been purposefully averted to discard the high contact resistance between the trace and such contacts.

In this study, tough and conductive hydrogels were printed by 3D printing method. The combination of thermo-responsive agar and ionic-responsive alginate can highly improve the shape fidelity. With addition of agar, ink viscosity was enhanced, further improving its rheological characteristics for a precise printing. After printing, the printed construct was cured via free radical polymerization, and alginate was crosslinked by calcium ions. Most importantly, with calcium crosslinking of alginate, mechanical properties of 3D printed hydrogels are greatly improved. Furthermore, these 3D printed hydrogels can serve as ionic conductors, because hydrogels contain large amounts of water that dissolve excess calcium ions. A wearable resistive strain sensor that can quickly and precisely detect human motions like finger bending was fabricated by a 3D printed hydrogel film. These results demonstrate that the conductive, transparent, and stretchable hydrogels are promising candidates as soft wearable electronics for healthcare, robotics and entertainment.

The ability to directly print compliant biomedical devices on live human organs could benefit patient monitoring and wound treatment, which requires the 3D printer to adapt to the various deformations of the biological surface. We developed an in situ 3D printing system that estimates the motion and deformation of the target surface to adapt the toolpath in real time. With this printing system, a hydrogel-based sensor was printed on a porcine lung under respiration-induced deformation. The sensor was compliant to the tissue surface and provided continuous spatial mapping of deformation via electrical impedance tomography. This adaptive 3D printing approach may enhance robot-assisted medical treatments with additive manufacturing capabilities, enabling autonomous and direct printing of wearable electronics and biological materials on and inside the human body.

The application of additive manufacturing, well known as 3D printing, in textile industry is not more totally new. It allows is giving significant increase of the product variety, production stages reduction, widens the application areas of textiles, customization of design and properties of products according to the type of applications requirement. This paper presents a review of the current state-of-the-art, related to complete process of additive manufacturing. Beginning with the design tools, the classical machinery building computer-aided design (CAD) software, the novel non-uniform rational B-spline (NURBS) based software and parametric created models are reported. Short overview of the materials demonstrates that in this area few thermoplastic materials become standards and currently a lot of research for the application of new materials is going. Three types of 3D printing, depending on the relation to textiles, are identified and reported from the literature—3D printing on textiles, 3D printing of flexible structures and 3D printing with flexible materials. Several applications with all these methods are reported and finally the main advantages and disadvantages of the 3D printing in relation to textile industry are given.

Biodegradable polymer microneedle (MN) arrays are an emerging class of transdermal drug delivery devices that promise a painless and sanitary alternative to syringes; however, prototyping bespoke needle architectures is expensive and requires production of new master templates. Here, we present a new microfabrication technique for MNs using fused deposition modeling (FDM) 3D printing using polylactic acid, an FDA approved, renewable, biodegradable, thermoplastic material. We show how this natural degradability can be exploited to overcome a key challenge of FDM 3D printing, in particular the low resolution of these printers. We improved the feature size of the printed parts significantly by developing a post fabrication chemical etching protocol, which allowed us to access tip sizes as small as 1 μm. With 3D modeling software, various MN shapes were designed and printed rapidly with custom needle density, length, and shape. Scanning electron microscopy confirmed that our method resulted in needle tip sizes in the range of 1 – 55 µm, which could successfully penetrate and break off into porcine skin. We have also shown that these MNs have comparable mechanical strengths to currently fabricated MNs and we further demonstrated how the swellability of PLA can be exploited to load small molecule drugs and how its degradability in skin can release those small molecules over time.
