The shift from rapid prototyping to rapid manufacturing using 3D printing is prominent after the development of volumetric 3D printing, multi-material printing, and functional materials development. Fused filament fabrication (FFF) is a fast-growing additive manufacturing technology with widespread end-user applications. The key constraints to its growth are the lower surface and mechanical properties compared to conventional manufacturing paradigms. The goal of this review is to look at the numerous pre-processing and post-processing parameters for the property enhancement of FFF. Preprocessing methods included optimization of process parameters (infill percentage, pattern, layer height, nozzle and platform temperature, raster angle and width, build orientation, and air gap) and adaptive slicing techniques.Mechanical (hot air jetting, barrel finishing, sand blasting, laser polishing, etc.), chemical (vapor smoothing, dipping, plating, and painting), and thermal (thermal annealing and normalizing) post-processing techniques were successful in improving the mechanical strength and surface finish of fused filament fabricated parts. This paper outlines the various methodologies a FFF user could incorporate for enhancing the final finished product's properties. The potential future prospects for the development of the 3D printing sector are also examined.

“…Additionally, research on the materials in the field of 3D-printed clothing has also made preliminary progress [ 45 ]. Cakar [ 46 ] measured and analyzed the printed samples made from polylactic acid (PLA (soft)), PLA+ (hard) and Filaflex (TPE, namely, “Thermoplastic Elastomer”). The results show that Filaflex is the best material for the process of 3D printing.…”

Clothing is considered to be an important element of human social activities. With the increasing maturity of 3D printing technology, functional 3D printing technology can realize the perfect combination of clothing and electronic devices while helping smart clothing to achieve specific functions. Furthermore, the application of functional 3D printing technology in clothing not only provides people with the most comfortable and convenient wearing experience, but also completely subverts consumers’ perception of traditional clothing. This paper introduced the progress of the application of 3D printing from the aspect of traditional clothing and smart clothing through two mature 3D printing technologies normally used in the field of clothing, and summarized the challenges and prospects of 3D printing technology in the field of smart clothing. Finally, according to the analysis of the gap between 3D-printed clothing and traditionally made clothing due to the material limitations, this paper predicted that the rise in intelligent materials will provide a new prospect for the development of 3D-printed clothing. This paper will provide some references for the application research of 3D printing in the field of smart clothing.

“…However, as 3D printing is to stack the molten wire layer by layer into 3D parts, bubbles, oxides, and pores cannot be avoided due to the fast cooling speed and weak interface bonding during 3D printing. 12 Both bubbles and pores may become the nucleus of crack and result in the decline of mechanical properties of 3D printing products. Damages such as cracking, debonding, delamination may be induced by repeated large deformation.…”

3D printing technology combined with thermoplastic polyurethane (TPU) is increasingly being used in flexible electronics. However, the defects induced by 3D printing may degrade the mechanical properties of the TPU substrates significantly and result in the decrease in breaking elongation, tensile strength, and waterproof performance. In this article, we investigate the effect of heat treatment on improving the mechanical and waterproof properties of TPU substrate experimentally. The results show that heat treatment can effectively reduce the defects such as bubbles and pores inside the 3D printed TPU structure and increase the bonding area of the filament, and thus making the 3D printed TPU structure dense. After heat treatment at 180 C, the tensile strength and elongation at break of 3D printed TPU samples in the fiber direction (filling angle of 0 ) increased by 67% and 38%, respectively. The tensile strength and elongation at break in the bonding direction (filling angle of 90 ) increased by 100% and 75%. In addition, the waterproof performance of the samples has been enhanced, and the water contact angle of the surface has increased from 90.4 to 95.25 . Therefore, the heat treatment can effectively improve the mechanical properties and waterproof performance of 3D printed TPU samples.
