In recent years, 3D printing has gradually appeared in people’s field of vision. The addition of wood in thermoplastics improve their some mechanical properties such as tensile and bending modulus without affecting its biodegradability. The decrease in the cost of filaments may enlarge the utilization of biodegradable filaments after the disposal in near future. Smallscale elements used in furniture production, such as connector fittings or fasteners for shelves, may give functional and structural
properties without significant investment. 3D-printed connections are suitable when the the production complex shaped connectors and quick disassembly are required, to reduce the product’s weight and price

Formaldehyde is considered a health hazard, hence the wood-based panels must be within the limits imposed by the strictest regulations regarding the formaldehyde release. New national and international international regulations of formaldehyde emission from wood-based panels widely used in furniture industry were investigated in this study. The results of the study can be useful for the woodbased panel factories to follow the standards and regulations in terms of formaldehyde emission.

Furniture made of corrugated cardboard is environmentally friendly, cheap and allow a construction of complex geometry in design and ergonomics of wide application. They may have functional value, art direction, etc. The application of advanced technological means which support the design process of furniture made of cardboard allows optimization of the complete process of creating a sustainable design.
