What could be a consequence of selecting inappropriate materials for FDM printing?

Selecting inappropriate materials for Fused Deposition Modelling (FDM) printing can significantly impact the success of the printing process, particularly by increasing the likelihood of print failure. Each 3D printing material has specific properties, including melting point, viscosity, adhesion characteristics, and layer bonding capabilities, which are critical for achieving successful prints. Using a material that does not align with the printer's specifications can cause issues such as poor layer adhesion, warping, or nozzle clogging, leading to incomplete or failed prints.

Additionally, inappropriate materials may not withstand the thermal and mechanical stresses applied during the printing process, exacerbating the risk of failure. Factors such as moisture absorption can also degrade certain filaments over time, leading to erratic extrusion or surface defects in the final product. This choice underlines the importance of selecting the right material for the intended application, taking into account the material compatibility with the printer and the required performance characteristics of the printed object.
