The presented research article shows a functionally graded lattice as an infill structure in designing a 3D printed mechanical element—a bicycle crank arm. The authors want to answer the fundamental question: whether the functionally graded lattice structures can efficiently improve structural performance and how they can be implemented in real complex components. Intuitively, everyone senses that using such elements must bring profit. A good example might be nature, which commonly reaches for such a solution in the skeletons of animals and humans. Two aspects determine their realisations: the lack of adequate construction and analysis methods and the limitations of existing manufacturing methods. Thus, the authors used relatively simple crank arm design and design exploration methods for structural analysis. The design exploration method enabled us to find the optimum solution efficiently. A developed prototype was created utilising additive manufacturing. One of the 3D printing methods - fused filament fabrication technology for metals, allowed the prototype of a crank arm with the optimised infill to be made. As a result, the authors developed a lightweight and manufacturable crank arm showing the new construction and analysis method implementable in similar 3D printed elements.

“…In past research, Gutiérrez-Moizant et al (2020) studied comparing the finite element model with the experimental results of a bicycle crank arm. In a universal dynamic test bench, the structural integrity of the crank arm was analyzed to know the component tiredness behavior [4]. Ismail et al (2020) applied topology optimization and surface response methods to optimize the geometry of and experimental validation of the bicycle crank arm [5].…”

The demand for increased performance both in the professional and amateur sectors and the inclusion of the bicycle in the city as a clean, silent, inexpensive, and healthy personal transport, is responsible for the technological growth of the industry. This study aims to analyze the effect of the design parameters on the bicycle crank arm and to find the best design value within the range for minimal defects. The strength of the structure design is significant to ensure the performance of the bicycle crank arms. To solve this problem, several design structures and parameters were studied. The selected parameters in this study are crank arm length, width, thickness, number of cranks spider, and rib design. Von-misses stress, strain, and displacement are selected as dependent variables. Aluminium Alloy 6061-T6 is the selected material in this study. The external load of 1000 N force was applied in the y-direction. The length analysis results show that 160 mm length, 30 mm width, and 10 mm thickness with five crank spiders and pocket design arm have the lowest stress, strain, and displacement. By bringing a new alternative to the crank's arm structure, the cost of the manufacture will be reduced. At the same time, it can help precisely improve the rigidity of producing complex 3D shapes.

The significance of lightweight designs has become increasingly paramount due to the growing demand for sustainability. Consequently, this study aims to demonstrate the potential of utilising a functionally graded lattice as an infill structure in designing an additively manufactured bicycle crank arm to achieve construction lightness. The authors seek to determine whether functionally graded lattice structures can be effectively implemented and explore their potential real-world applications. Two aspects determine their realisations: the lack of adequate design and analysis methods and the limitations of existing additive manufacturing technology. To this end, the authors employed a relatively simple crank arm and design exploration methods for structural analysis. This approach facilitated the efficient identification of the optimal solution. A prototype was subsequently developed using fused filament fabrication for metals, enabling the production of a crank arm with the optimised infill. As a result, the authors developed a lightweight and manufacturable crank arm showing a new design and analysis method implementable in similar additively manufactured elements. The percentage increase of a stiffness-to-mass ratio of 109.6% was achieved compared to the initial design. The findings suggest that the functionally graded infill based on the lattice shell improves structural lightness and can be manufactured.
