Depending on your area of interest, "FFFM" can refer to a specific type of 3D printing or a category of biological fermentation. 1. Fused Filament Fabrication Method (FFFM)
: This community of microbes is specifically responsible for product synthesis and metabolic functions, such as substrate utilization [18, 19]. Depending on your area of interest, "FFFM" can
: The succession and activity of these microbes are primarily driven by environmental factors like moisture, acidity, and humidity in early stages, while oxygen content becomes critical during middle stages [18, 19]. Depending on your area of interest
: The high manufacturing temperatures can limit its use for certain sensitive biological cells [29]. 2. Fermentation Functional Microbiota (FFM/FFFM) such as substrate utilization [18
