“…In the case of S 1 being 0, the cylinder model represents a unidirectional deposited part that is entirely deposited in the axial direction. It is now clear from equations (2)(3)(4)(5)(6)(7)(8)(9) and (2-8) that the elastic modulus E 2 of the substrate determines the mechanical properties of the cylinder model.…”

“…6 A great deal of research has been done by scholars worldwide on 3D printing of CFRP. Ramesh et al 7 and Ramesh and Niranjana 8 investigated the effect of various process parameters on the 3D printing of fibre-reinforced composites.Hou et al have designed samples of variable stiffness structures and tested bending properties of the samples. Experimental results indicate that the flexural modulus and impact strength of a suitable variable stiffness structure are increased by 70% and 65% respectively compared to a homogeneous structure.…”

Continuous fibre reinforced polymer (CFRP) have a distinctive anisotropic character. In traditional 3D printing processes, deposition direction cannot be adjusted. As a result, the performance of CFRP parts is deficient in the fixed direction. To address the issue, this paper proposes a variable deposition direction (VDD) 3D printing process for CFRP. The process optimises the mechanical properties of the moulded part by adjusting the direction of deposition. The principles and processes of the VDD 3D printing are described in detail. Then, using the hollow cylinder as an example, a mathematical model of the variable deposition direction structure is developed, and subsequent simulations is conducted to evaluate its mechanical properties. In the experimental part, the composite material used has a fibre content of 20% and consists of PETG and carbon fibres. The VDD hollow cylindrical parts have been printed to verify the feasibility of the process. And performance testing experiments were carried out on a variety of test specimens of different structures with VDD. The results show that adjusting the deposition direction of the CFRP can greatly improve the tensile properties of hollow cylinder. The tensile properties of a suitable structure with VDD were improved by a factor of 69.4 compared to a single deposition direction structure. And the actual tensile situation is consistent with the simulation. To summarise, the proposed method can effectively solve the defects of the traditional process and optimise the mechanical properties of the moulded parts.

“…The strength limitation becomes even more critical for designing lattice structures that combine lightweight and high specific strength 5,6 . FFF of fiber‐reinforced thermoplastics offers an effective route to achieving the high strength and modulus needed for structural applications 7–9 . In this work, we experimentally investigate the performance of solid and lattice parts made of chopped carbon fiber reinforced polyamide (PA) to assess the feasibility of these novel structures for load‐bearing applications.…”

This article investigates the mechanical behavior of polyamide and carbon fiber‐reinforced (CFR) polyamide structures produced by Fused Filament Fabrication. CFR improves solid polyamide's tensile strength and modulus by more than 200% and 800%, respectively. The enhancement is highest in the parallel raster due to the alignment of the fibers in the printing direction. The compression tests of gyroid, honeycomb, and Voronoi cellular structures revealed the effect of geometry and fiber reinforcement on energy absorption performance. CFR gyroid infill offers the best performance with a specific energy absorption capacity reaching 10 kJ/kg and an efficiency close to 50%. Fiber reinforcement improves energy absorption by a factor of four or higher while increasing the weight by only 10%. The energy absorption capacity of the reinforced polyamide offers enormous potential for developing new lightweight load‐bearing and impact‐absorbing structures.

Additive manufacturing (AM) has been gaining pace, replacing traditional manufacturing methods. Moreover, artificial intelligence and machine learning implementation has increased for further applications and advancements. This review extensively follows all the research work and the contemporary signs of progress in the directed energy deposition (DED) process. All types of DED systems, feed materials, energy sources, and shielding gases used in this process are also analyzed in detail. Implementing artificial intelligence (AI) in the DED process to make the process less human-dependent and control the complicated aspects has been rigorously reviewed. Various AI techniques like neural networks, gradient boosted decision trees, support vector machines, and Gaussian process techniques can achieve the desired aim. These models implemented in the DED process have been trained for high-precision products and superior quality monitoring.
