“…[30][31][32][33] However, in the case of FDM SFRPCs, the mutual effects of voids and bulk anisotropy induced by the reinforcement lead to an infill pattern dependence of the mechanical properties. [34][35][36][37][38] In the present investigation and according to the literature, 35,36 best performance in terms of E and σ m was obtained for raster angle 0 , while the 90 infill pattern produced the lowest properties with a percentage deterioration around 60%. The virgin and recycled AM_F±45 materials show the highest ε b , in agreement with the literature, 35 and approximately three times higher than for the respective AM_F0 materials.…”

“…Several investigations show that the mechanical properties of net polymers such as ABS and PLA are not significantly influenced by the infill direction 30–33 . However, in the case of FDM SFRPCs, the mutual effects of voids and bulk anisotropy induced by the reinforcement lead to an infill pattern dependence of the mechanical properties 34–38 . In the present investigation and according to the literature, 35,36 best performance in terms of E and σ m was obtained for raster angle 0°, while the 90° infill pattern produced the lowest properties with a percentage deterioration around 60%.…”

The static behavior of specimens made of virgin and recycled short glass fiber‐reinforced polypropylene filled with mineral filler has been studied. Specimens were produced by means of pellet additive manufacturing (PAM) adopting different infill patterns to investigate the influence of material anisotropy. For comparison purposes, the mechanical properties of the same virgin and recycled materials were investigated also with injection‐molded specimens. The fracture behavior was investigated by analyzing the damage at a macroscopic as well as microscopic level. As the main outcome, it was noted that both the manufacturing and recycling processes play a crucial role in the damage mechanics of the specimens, thus explaining the different fracture behaviors noted at the macroscale.

“…The FDM 3D printing technology is easy to operate, low cost, and has high material utilization, which is one of the most commonly used 3D printing technologies [ 62 ]. The disadvantage of the FDM 3D printing technology is that there are obvious stripes on the surface of the finished product, and the connection between layers is weak [ 63 , 64 , 65 ]. The conductive composites prepared with conductive carbon filler have excellent mechanical and conductive properties and have great application prospects in structural electronics, supercapacitors, and multi-shape conductive electrodes, etc.…”

Carbon material is widely used and has good electrical and thermal conductivity. It is often used as a filler to endow insulating polymer with electrical and thermal conductivity. Three-dimensional printing technology is an advance in modeling and manufacturing technology. From the forming principle, it offers a new production principle of layered manufacturing and layer by layer stacking formation, which fundamentally simplifies the production process and makes large-scale personalized production possible. Conductive carbon materials combined with 3D printing technology have a variety of potential applications, such as multi-shape sensors, wearable devices, supercapacitors, and so on. In this review, carbon black, carbon nanotubes, carbon fiber, graphene, and other common conductive carbon materials are briefly introduced. The working principle, advantages and disadvantages of common 3D printing technology are reviewed. The research situation of 3D printable conductive carbon materials in recent years is further summarized, and the performance characteristics and application prospects of these conductive carbon materials are also discussed. Finally, the potential applications of 3D printable conductive carbon materials are concluded, and the future development direction of 3D printable conductive carbon materials has also been prospected.

“…Naranjo-Lozada et al [ 23 ] observed small improvements in tensile strength on specimens printed with chopped carbon fiber reinforced PA6 compared to unreinforced ones. Peng et al [ 34 ] observed that the printing bed temperature had a positive influence on the tensile strength of specimens printed with a tailor-made PA6 filament reinforced with 10% short carbon fibers. Handwerker et al [ 35 ] investigated the effect of annealing conditions on the mechanical properties of chopped carbon fiber-reinforced PA6 parts along the build-up direction.…”

Fused-Filament Fabrication of Short Carbon Fiber-Reinforced Polyamide: Parameter Optimization for Improved Performance under Uniaxial Tensile Loading

2022

This study intends to contribute to the state of the art of Fused-Filament Fabrication (FFF) of short-fiber-reinforced polyamides by optimizing process parameters to improve the performance of printed parts under uniaxial tensile loading. This was performed using two different approaches: a more traditional 2k full factorial design of experiments (DoE) and multiple polynomial regression using an algorithm implementing machine learning (ML) principles such as train-test split and cross-validation. Evaluated parameters included extrusion and printing bed temperatures, layer height and printing speed. It was concluded that when exposed to new observations, the ML-based model predicted the response with higher accuracy. However, the DoE fared slightly better at predicting observations where higher response values were expected, including the optimal solution, which reached an UTS of 117.1 ± 5.7 MPa. Moreover, there was an important correlation between process parameters and the response. Layer height and printing bed temperatures were considered the most influential parameters, while extrusion temperature and printing speed had a lower influence on the outcome. The general influence of parameters on the response was correlated with the degree of interlayer cohesion, which in turn affected the mechanical performance of the 3D-printed specimens.
