Which of the following is NOT a common issue when printing with FDM technology?

Fused Deposition Modeling (FDM) technology is widely used in additive manufacturing, and it is important to understand the common issues associated with this process. Overheating of the resin is not applicable to FDM because this technology primarily uses thermoplastic filaments, such as PLA, ABS, or PETG, which are heated to a specific melting temperature to create the printed layers. Unlike resin-based printing technologies, where overheating can lead to problems, FDM relies on the proper heating and cooling of the filament to achieve layer adhesion and structural integrity.

The other issues listed, such as warping of parts, excessive print speed, and layer adhesion failure, are common challenges in FDM printing. Warping can occur as the material cools and contracts, leading to distortion in the parts. Excessive print speed may compromise the print quality, leading to incomplete layers or misalignment. Layer adhesion failure can result from insufficient heat, improper temperature settings, or material incompatibility, leading to weak bonds between layers which can compromise the final part's strength. Understanding these issues helps operators adjust their settings and improve print quality effectively.
