“…Here, another method of additive process of FDM technique is unworkable to print glass reinforced Nylon-6 gears. Because the research work is underway on the development of Nylon-6 filament [39][40][41][42] which is to be used in existing original equipment manufacturer (OEM) FDM system without changing hardware/software of the system. Due to this reason, it is not readily available in Indian market.…”

Effect of strain rate on the single tooth strength of nylon-based gear has been investigated using a newly designed testing fixture. An adjustable single tooth testing fixture has been designed and developed for the purposed of single tooth loading test which is able to accommodate the gear with varying thickness. Injection molded nylon-6 and SLS (selective laser sintering) printed glass filled nylon-6 standard involute and asymmetric gear tooth have been investigated for their single tooth loading test at three different strain rates of 0.0003, 0.003, and 0.01 per sec. Single tooth strength for both injection and printed gear is found to increase with the increase in strain rate. Injection molded single gear tooth undergone bending failure whereas SLS printed gear tooth shows fracture failure. Resistance to single tooth deflection at higher strain rate has drastically increased for injection molded standard involute (IS) gear tooth by 23% whereas, asymmetric gear tooth IA20 followed by IA34 shows slight increment. SLS printed asymmetric gear tooth PAG20/34 exhibits maximum single tooth strength among all three types of printed gears at all the three strain rates. At higher strain rate of 0.01 per sec, single tooth strength dominates by tooth profile geometry whereas, at lower strain rate of 0.0003 per sec, it dominates by tooth profile geometry and microstructure.

Background. Additive technologies based on Fused Deposition Modeling (FDM) modeling methods attract a lot of attention from both industry and research groups, which is explained by low investment costs, ease of production, etc. If the processing parameters are correctly selected, products with mechanical properties close to products obtained by traditional technologies can be obtained. Objective. Practical implementation of the modernized technology for 3D printing of Polylactid Acid (PLA) samples reinforced with continuous Kevlar fiber using the FDM method and determination of their mechanical properties. Methods is based on experimental and theoretical studies of the limit of tensile strength and modulus of elasticity of the composite and includes testing of samples on the SHIMADZU AGS-X testing machine and solving the inverse problem. Results. Experimental samples of thermoplastic composite (PLA+Kevlar fiber Æ0.3 mm) were tested for tension. It was found that the tensile strength of the reinforced composite compared to the unreinforced one with a Kevlar volume fraction of about 12% increases by 2.38 times, and the modulus of elasticity increases by 1.45 times. With a confidence interval of 0.68, the error of determining the ultimate tensile strength is 3.5%, and the modulus of elasticity is 4.5%. A theoretical dependence was obtained for predicting the modulus of elasticity of thermoplastic composites in the range of changes in the degree of reinforcement up to 15%. Conclusions. The application of additive technologies based on FDM for 3D printing of thermoplastic composites with increased mechanical properties is substantiated.

“…Pipes, plastic wires, 3D printer filaments, plastic film, and wire coating are applications of single screw extrusion. [34][35][36] This type of extruders is far more inexpensive and possess less shear as compared with other screw extruders. They have high throughput and wide range of materials can be processed due to ease in operation.…”

Fused deposition modeling (FDM) is one of the leading emerging technologies of Industry 4.0, which has been employed to develop sustainable engineering products, customized implants and sophisticated biomedical devices. However, the mechanical strength and durability of 3D printed parts is still lower than its conventional counterparts, which restrict its widespread use. In this regard, the use of short fibres (i.e. natural or artificial) and advanced nanomaterials to reinforce the existing polymer matrix has been drastically increased to improve the load bearing capacity of FDM printed parts. Hence, this article aims to provide a systematic review on thermoplastic composite structure prepared through FDM technology and summarizes the current knowledge about the use of various additives to improve the overall quality FDM parts. Moreover, the common defects associated with FDM printed composite structures and the methods required to improve the quality of FDM composite parts are discussed in this article.
