Filamentous fungi create complex structures, such as mushrooms, using filaments made of fungal cells, called hyphae. Previous research shows that the presence distinct types hyphal can affect mechanical properties mushrooms they form. This study characterizes structure and a monomitic white mushroom (one type filaments) dimitic maitake (two filaments). characterization includes on micro‐ macroscale imaging, compression testing, nanoindentation. Using this experimental data imaging observation, stochastic cellular is proposed simulated 3D Voroni structures. Compression test simulations are conducted to investigate effects filament orientation these filamentous network Five main angles used: horizontal (0°), 30°, 60°, vertical (90°). These result in variable stiffness without addition fibers different properties, suggesting be manipulated alter fungi‐based or fungi‐inspired materials. lays foundation for designing structures with tunable directions.

Purpose In this study, response surface methodology (RSM) is applied to a three-point bending stiffness analysis of low-cost material (PLA) specimens printed using FDM technology analyze the performance different internal lattice structures (Octet and IsoTruss principally). The purpose study extend definition from discrete (lattice) model an analytical one for its use in subsequent design phases, capable optimizing type cell be used defining parameters find best stiffness-to-weight ratio. Design/methodology/approach representative function their mechanical behavior extrapolated through two-variable polynomial based on size thickness beam elements characterizing it. obtained thanks several tests performed according scheme RSM. An estimation errors due discontinuities physical also conducted. Physical showed some divergences virtual (ideal) specimens. Findings allowed validate RSM models proposed predict system as size, cells vary. Changes weight follow linear quadratic models, respectively. This generally allows optimal points where ratio at highest. Originality/value Although literature provides numerous references studies parameterizing structures, industrial/practical applications concerning are often still detached theoretical research limited achieving functioning rather than ones. approach here described aimed overcoming limitation. software nTop. Subsequent have validated reliability derived method’s application.
