“…During the last years, 3D printing has more and more emerged from a rapid prototyping to a rapid printing technology, allowing for producing single objects or complicated shapes which cannot be produced in a different way. One of the problems in the utilization of 3D printing techniques for a broader range of applications is the relatively low mechanical stability due to the layered production process, for which several research groups suggested different possible solutions [1][2][3].…”

3D printing on textile fabrics can be used to create composites with position-dependent mechanical, water-resistant, magnetic or other properties. An important prerequisite to use such composites technologically or for design purposes is a sufficient adhesion between both materials. While previous studies revealed that soft, elastic printing polymers were advantageous to prepare connections with a high adhesion, not much research has been performed yet on the dependence of the adhesion on textile fabric structure, heat post-treatment, and the influence of washing, which is necessary for most applications of such composites. Here we investigate composites from thermoplastic polyurethane (TPU) 3D-printed on two different woven cotton fabrics. Besides the expected strong correlation of the adhesion with the distance between nozzle and printing bed, we find a higher adhesion on the thinner fabric and an increase in the adhesion after one washing cycle.

“…Currently, universal plastics such as acrylonitrile butadiene styrene (ABS) and poly(lactic acid) (PLA) have a wide range of applications in the field of 3D printing 7–12 . However, their lower glass transition temperature means that it is difficult for them to meet the needs of aerospace, electronic appliances and other high temperature resistance fields.…”

Fused deposition modeling (FDM) has been successfully applied to the manufacturing of poly(ether ether ketone) (PEEK) special engineering plastics. However, due to the unavoidable defects caused by FDM technology and the high melt viscosity of PEEK, 3D printed PEEK parts have poor mechanical properties. In this study, the mechanical properties and microstructure of PEEK printed with different nozzle temperatures and having various molecular weights were researched in detail. The results showed that PEEK‐033G with medium molecular weight had good fluidity. With a nozzle temperature of 410 °C and using a high‐temperature chamber 3D printing system, the defects of 3D printed PEEK‐033G were reduced significantly, and the tensile strength and flexural strength could reach 96 and 115 MPa, which is close to the performance obtained using injection molding. In addition, the tensile strength in the Z‐axis direction was applied to characterize the interlayer bond strength. With a decrease of the viscosity of PEEK, an increase of interlayer bond strength ensued. It is expected that these findings could provide more insight for 3D printing of PEEK. © 2020 Society of Chemical Industry

“…A similar issue is described in research [9][10][11][12][13], where the properties and behavior of the ABS-like material were described. This material was subsequently compared also with the PLA material in the paper by the authors Oviedo et al [14], where dimensional deviations of the samples were defined within the tolerances defined by standard test protocols. A comparison of the behavior of materials conventionally used in additive production has also been described by the authors [15][16][17][18][19].…”

Advanced Configuration Parameters of Post Processor Influencing Tensile Testing PLA and Add-Mixtures in Polymer Matrix in the Process of FDM Technology

The present paper focuses on the configuration possibilities of post -processor influencing mechanical properties of a given test sample produced by the FDM printer from different materials. The research consists of assessing the composite material configurations through a static tensile test conducted on 80 samples produced. The samples were produced based on ISO 527-2 standard, type 1A, with a horizontal position and a layer height of 0.2 mm. The individual samples consisted of four basic groups of materials—the pure Polylactic acid (PLA) plastic (reference sample), and three composite samples with admixtures—PLA matrix with a copper admixture, PLA matrix with an iron admixture, and PLA matrix with a steel admixture. The static tensile test was conducted at a test speed of 5 mm/min. During the research, reference samples (pure PLA) were assessed in five orientations. Samples made of the PLA composite materials with admixtures were manufactured, tested, and evaluated only in the 0° orientation. The paper concludes by comparing the results of measurement with the original material, free from additives, and with the researched influence of the orientation of the prints on the resulting mechanical properties of shear samples and their surface structure. In the conducted experiments, the lowest tensile strength has been demonstrated in test samples the orbital transitions and the upper surface layers of which were parallel to the infill.
