“…The 3-D printed objects are used as prototypes, complex aerospace, and automobile components, in visual aids, physically functional parts, and models for educational presentations which covers almost 25% of the AM industry applications. 9–13 According to Wohler’s report, 14 the aerospace industry is utilizing about 18.2% of the total AM market, and thus AM is positively anticipated to carry high potential perspective in the future. Additionally, FDM is showing great prospects for product development with the ability to contest against conventional polymer processing techniques.…”

Laminar composites have widespread applications in the automotive and aircraft industry. This research was aimed to investigate the suitability of fused deposition modeling to produce multi-material laminar composites. Composites comprising of two dissimilar laminates, named as hybrid composites, were printed from acrylonitrile butadiene styrene filament and carbon fiber-reinforced polylactic acid filament (a composite filament) by varying different printing parameters. Tensile tests were conducted to examine the mechanical performance of the produced composite sheet. A detailed analysis of the results revealed that a high ultimate tensile strength is primarily achieved by setting low values of printing speed, layer height, and clad ratio while high elongation is obtained by employing low printing speed, medium layer height, and high clad ratio. The optimum printing conditions were sought out through desirability function with an objective to simultaneously enhance all the considered properties. Further, the composite sheet exhibited a reasonably good combination of tensile properties as compared to its monolithic constituent sheets. Based on the results, it is concluded that the bi-material laminating approach employed herein can produce printed structures with desired properties.

“…Three-dimensional printing has been becoming one of the most rapidly developed and widely used technology in several applications (Rimašauskas et al , 2019). Rapid prototyping, sustainability, flexible production technique and cost-effectiveness are counted as advantages of 3D printing in many studies (Sitotaw et al , 2020; Goncu-Berk et al , 2022; Chakraborty and Biswas, 2020; Jackiewicz, 2017). These benefits make 3D printing even more popular in many different fields including the textiles and fashion industry.…”

Purpose The purpose of this study is to investigate surface treatments and fiber types on adhesion properties polylactic acid (PLA) three-dimensional (3D) parts printed on woven fabrics. Design/methodology/approach The cotton, flax and jute fabrics were exposed to alkali, hydrogen peroxide, stearic acid and ionic liquid treatments to modify surface characteristics before PLA 3D printing. The modification efficiency was assessed with Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) analyses. Then, fused deposition modeling (FDM) printer and PLA filament were used for 3D printing onto the untreated and treated fabrics. The adhesion strength between the fabrics and PLA 3D parts were tested according to DIN 53530 via universal tensile tester. Findings The fabric structure is effective on adhesion force and greater values were observed for plain weave fabrics. Maximum separation forces were obtained for alkali pretreated fabrics among jute and cotton. Hydrogen peroxide treatment also increased adhesion forces for jute and cotton fabrics while decreasing for flax fabrics. Stearic acid and ionic liquid treatments reduced adhesion forces compared to untreated fabrics. Treatments are effective to alter adhesion via changing surface chemistry, surface morphology and fabric physical properties but display different effects related to fabric material. Originality/value This study provides experimental information about effects of different fiber types and surface treatments on adhesion strength of PLA 3D parts. There is limited research about comprehensive observation on 3D printing on cellulosic-woven fabrics.

Biopolymer-based composites, which are being employed extensively in biomedical applications have exceptional physical and mechanical properties. However, printing composites is a challenging task for biomedical applications. The current work highlights the impact of process parameters of fused filament fabrication (FFF) technology, that is, layer height, number of loops, nozzle temperature, and a nonprocess parameter, that is, weight percentage of alumina on ultimate tensile strength, ultimate flexural strength, and ultimate compression strength of polylactic acid (PLA)-alumina composite. Response surface methodology (RSM) has been implemented to construct the tests. The regression model demonstrated how various parameters and their interaction affected output responses. The surface plots for noticeable interactions have also been plotted. The outcome revealed that parameter control and optimization have vital impact on mechanical properties. The optimum value for maximum mechanical strengths has been obtained at layer height 0.1 mm, number of loops 4, nozzle temperature 195 C, and weight percentage of alumina as 1.5%. Later a case study has been performed with obtained optimized parameters with porous structures for biomedical applications and found that the properties such as surface finish, and dimensional accuracy were unaltered during the optimization process.
