Narrative review demonstrates the impact of process parameters on biopolymer extrusion, highlighting technical challenges for advancing additive manufacturing.
Additive Manufacturing represents a well-known and fast growing material processing technology. Printed part is formed by adding material layer by layer until the part is finished without requiring any additional molds. Therefore, using Additive Manufacturing can save time and costs in comparison to commercial production methods particularly when manufacturing complex prototypes or small batch series. Another advantage of Additive Manufacturing is its freedom of design. This review is focused on material extrusion, a specific Additive Manufacturing technology. It begins with a short overview of the most common materials processed with this technology. Subsequently, we discuss several processes and machine parameters in material extrusion as well as their influence on the printing process and on the final properties of the printed part. Based on this knowledge, various challenges in material extrusion are also identified. These challenges must be resolved in order to improve the material extrusion process.
