Abstract

In recent years, additive manufacturing has gained growing importance in industrial, healthcare, and prototype development. FDM (Fused Deposition Modeling) and resin tech-nologies dominate desktop 3D printing, offering diverse materials, including PLA (polylactic acid) and PETG (polyethylene terephthalate glycol). PLA is biodegradable, compostable, and recyclable, while PETG offers higher impact and heat resistance, making it better suited for industrial applications despite being non-biodegradable. The potential of 3D printing extends beyond polymers, with applications in metalworking and mechanical engineering. While wood-containing PLA filaments are available, the use of additive manufacturing in the woodworking industry remains underexplored. This review, complemented by original re-search, seeks to develop proprietary wood-based filaments for additive manufacturing. Key considerations include material strength, weight, surface quality, hygroscopicity, and dimensional stability. The cost-effectiveness and eco-friendliness of FDM technology make it widely accessible, yet demand persists for stronger, lighter, and sustainable materials. Cur-rent wood-based materials allow for high-quality, aesthetic products, but limited data on wood species, concentration, and particle size distribution presents opportunities for further research to optimize material performance. In this paper there were also compared some typical wood-based filaments available on market.
