“…The construction plan used for the PB manufacturing was the XYZ plan, represented in Figure 3 below. Regarding the references of XYZ and YXZ print directions, better mechanical resistance and, at the end of the print, good dimensional precision in the printed body were achieved with FDM technology [23][24][25]. For the manufacture of PB and execution of the tensile test of this work, it was considered as a controlled parameter the density of infill in Tri-Hexagonal format, obtained by Cura Ultimaker software version 3.6.0.…”

“…For assembly and finishing the average time consumed was 3 h. The final weight of the fully assembled device was 263.90 g. The estimated cost of the device is $60.82, which is a low cost compared to the cost of conventional prostheses, with values ranging from $316.30 to $1408.75 [33,34]. In addition, in the global market, there are upper limb prostheses with sophisticated operating systems that cost between $25,000 and $58,000 per unit [25,35,36]. Regarding the weight achieved in the prosthesis (less than 270 g) developed in this project, it is essential for the user in the adaptation process, to have prosthetic devices that have the ability to combine mechanical strength and low weight, being extremely important factors in the rehabilitation process.…”

This work aims to develop a low-cost human hand prosthesis manufactured through additive manufacturing. The methodology used for the development of the prosthesis used affordable and low-cost materials in the market. Tensile testing was performed to estimate the mechanical properties in order to verify the resistance of the printing material used. Afterwards, the mechanical feasibility study executed on the device was performed using finite element method. In conclusion, we can observe fundamental factors that influence the 3D printing process, especially in relation to its printing parameters and mechanical properties. Maximum stress, yield stress, modulus of elasticity, elongation, and hardness are the prominent properties that should be considered when choosing the polymeric material. The numerical simulation showed that the structure of the prosthesis did not present plastic deformations to the applied loads, proving its mechanical viability.

“…Compared with traditional techniques for polymer processing, FFF exhibits great advantages in flexible and moldless manufacturing of customized components with complex shapes, which is also highlighted with a low material waste rate. With the development of the FFF technique, a lot of commercially available polymeric materials, such as polylactic acid, 1,2 acrynitrile butadiene styrene, 3,4 polypropylene (PP), 5–7 polycarbonate, 8,9 polyethylene terephthalate glycol‐modified, 10 polyamide, 11 and so forth, have been already successfully applied.…”

In the present work, microfibrillar composites (MFCs) consisting of polypropylene (PP) and poly(ethylene terephthalate) (PET) were successfully produced by melt extrusion and cold stretching. The resulting filaments were then printed using fused filament fabrication. The morphological results demonstrate that the highly oriented PET fibrils after stretching are still well preserved in the printed components. Since the printing process defines the alignment of the fibrils in the final component the fibers can be perfectly adapted to the load paths. Comparative analyses of the mechanical properties reveal that the PET fibrils act as an effective reinforcement in the 3D printed components, resulting in the superior mechanical performance of the PP/PET MFCs compared to a PP/PET blend and a neat PP. Due to the combination of material and innovative processing, the study opens up a new way of using the morphology‐based enormous potential of polymer fibers for lightweight, cost‐effective and recyclable full polymer solutions in compact components.

One of the most promising emerging innovations in personalized medication is based on 3D printing technology. For use as authorized medications, 3D-printed products require different in vitro tests, including dissolution and biocompatibility investigations. Our objective was to manufacture implantable drug delivery systems using fused deposition modeling, and in vitro tests were performed for the assessment of these products. Polylactic acid, antibacterial polylactic acid, polyethylene terephthalate glycol, and poly(methyl methacrylate) filaments were selected, and samples with 16, 19, or 22 mm diameters and 0%, 5%, 10%, or 15% infill percentages were produced. The dissolution test was performed by a USP dissolution apparatus 1. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide dye (MTT)-based prolonged cytotoxicity test was performed on Caco-2 cells to certify the cytocompatibility properties. The implantable drug delivery systems were characterized by thermogravimetric and heatflow assay, contact angle measurement, scanning electron microscopy, microcomputed tomography, and Raman spectroscopy. Based on our results, it can be stated that the samples are considered nontoxic. The dissolution profiles are influenced by the material properties of the polymers, the diameter, and the infill percentage. Our results confirm the potential of fused deposition modeling (FDM) 3D printing for the manufacturing of different implantable drug delivery systems in personalized medicine and may be applied during surgical interventions.
