“…In the late 1980s, Guo and Leu developed a technique called fused deposition modeling or FFF [ 142 ]. The FDM method is a quick method of prototyping complex geometric parts [ 142 , 143 ]. Computer-guided deposition of molten feedstock material is the basis of the FDM method, according to Cantrell et al [ 144 ].…”

“…The production of functional products must consider the mechanical properties of 3D-printed parts [ 143 ]. Using traditional methods (such as homogenous injection molding) typically results in different mechanical properties than those made using 3D printing, according to Song et al and Kim et al [ 157 , 158 ].…”

Embedded sensors (ESs) are used in smart materials to enable continuous and permanent measurements of their structural integrity, while sensing technology involves developing sensors, sensory systems, or smart materials that monitor a wide range of properties of materials. Incorporating 3D-printed sensors into hosting structures has grown in popularity because of improved assembly processes, reduced system complexity, and lower fabrication costs. 3D-printed sensors can be embedded into structures and attached to surfaces through two methods: attaching to surfaces or embedding in 3D-printed sensors. We discussed various additive manufacturing techniques for fabricating sensors in this review. We also discussed the many strategies for manufacturing sensors using additive manufacturing, as well as how sensors are integrated into the manufacturing process. The review also explained the fundamental mechanisms used in sensors and their applications. The study demonstrated that embedded 3D printing sensors facilitate the development of additive sensor materials for smart goods and the Internet of Things.

“…The findings demonstrate that altering the deposition direction can increase the elastic modulus, yield strength, and ultimate tensile strength of the samples with a vertical orientation by 6.1%, 13.6% and 6.2%, respectively. 21 Ezair et al propose a path planning method by filling the volume with curves. In this way they have completed the printing of a spiral structure in the topological direction of inflammation.…”

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.

“…Three-point bending tests showed maximum load, and flexural modulus increased as the effective density increased for all core shapes, but the rhombus core shape was the strongest. Bin et al [20] used a 3D printer on a robot arm to realize multi-plane layered printing. Compared with the tensile specimen produced by a traditional 3D printer, the elastic modulus, yield strength and ultimate tensile strength of the tensile specimen in the upright printing orientation have been improved.…”

“…It can be seen that, initially, path planning algorithms had the aim to improve the surface quality of AM printed parts, and reduce or avoid support structures. However, path planning algorithms have started to be used to improve the mechanical properties of 3D printing parts, mainly by changing the printing path of flat or curved layers [18][19][20][21][22][23][24]. To our knowledge, no print space path method has been used to increase the mechanical performance of printed parts.…”

Additive manufacturing has been applied in many fields, but its layer-by-layer fabrication process leads to a weak inter-layer bond strength of printed parts, so it cannot meet the higher requirements for mechanical properties of the industry. At present, many researchers are studying the printing path planning method to improve the mechanical properties of printed parts. This paper proposes a method to plan the printing path according to the actual stress of pipe parts, and introduces the realization process of an algorithm in detail, and obtains the printing control G-code. Additionally, a 5-axis material extrusion platform was built to realize the printing of polylactic acid pipes with plane and space skeleton curves, respectively, which verified the feasibility and applicability of the method and the correctness of the planning path with standard material extrusion filaments. Finally, the tensile and bending experiments prove that axial printing enhances the mechanical properties of pipe parts.
