Abstract:

: Additive manufacturing (AM), also known as 3D printing, encompasses a wide range of techniques for applications ranging from on-demand production to functional prototypes. 3D printing is mainly used in industrial sectors such as aerospace, automotive, medical, dental, construction, art and fashion. Fossil fuel-based materials, such as plastics and metals, as well as concrete, etc., are widely used to produce 3D-printed products. More recently, innovative 3D technologies using new bio-based renewable materials have shown promising results for everyday applications, opening up new opportunities for sustainable 3D printing in the future. This review reports on developments in the 3D printing of bio-based materials, direct or partial printing on textiles, etc., providing considerations, challenges and future outlooks.
