“…Production processes such as 3D printing technology are perfectly suited for the production of organic molds. Organic shapes are now increasingly used in the world because these shapes are perceived as optimized compared to traditional designs [5], [6]. Aircraft, cars, spacecraft and other weight-dependent segments will be made easier thanks to this rapidly evolving technology.…”

Generative design uses machine learning to emulate nature's evolutionary approach to design. Designers and engineers put design parameters such as material, size, weight, strength, manufacturing methods and costs into generative design software that explores all possible solution combinations and quickly generates hundreds or even thousands of design options. The article describes the production of a design backrest of the chair by combining several rapidly developing technologies. The selected backrest of the chair was digitized and subsequently subjected to design modifications in the Generative Design module of the Creo Parametric 7.0 system. The new design of the product was produced by means of a 3D printer to point out the possibility of saving the used production material of the design properties of the product while maintaining the required strength properties in the waste-free production method by additive technology.

Lattice structures are regularly employed in different industries ranging from biomedical to automobile and aircraft due to their excellent mechanical properties, outstanding load carrying and energy absorption capabilities, and better strength-to-weight ratio compared to traditional structures. On the other hand, fused deposition modeling (FDM) is a cost-effective method of additive manufacturing (AM) vastly used for plastic materials which are biocompatible, biodegradable, and environment-friendly in nature. The main aim of this study is to investigate the effect of FDM printing parameters, namely, layer height, nozzle temperatures, printing speeds, and bed temperatures, on a simple cubic lattice structure printed from PLA filament. The design of the experiment is conducted through L16 orthogonal array. After conducting compression tests, four significant outcomes, namely, modulus of elasticity, compressive strength, fracture strain, and modulus of toughness, are calculated from the stress–strain curves. Furthermore, an ANOVA (analysis of variance) test is carried out to find out the influence of each parameter. The analysis revealed that layer height is the most crucial parameter for modulus of elasticity and compressive strength. Secondly, the study also demonstrates the signal-to-noise ratio (S/N) analysis of each parameter and suggests the best manufacturing parameters, such as the layer height, printing temperature, printing speed, and bed temperature as 0.1 mm, 210 °C, 30 mm/s, and 60 °C, respectively, for the highest compressive strength. An SEM (scanning electron microscopy) analysis is carried out to examine the defects of the optimized lattice structure and found that the optimized structure has fewer defects in comparison to the non-optimized lattice core. Finally, based on these optimized parameters, a bone scaffold model is proposed for future biomedical applications. Graphical abstract
