Which characteristic is essential for a successful FDM print?

• A. Inconsistent layer adhesion
• B. Accurate dimensions
• C. Surface roughness
• D. Excessive stringing

Answer: (B)

Accurate dimensions are critical for a successful Fused Deposition Modeling (FDM) print because this characteristic directly affects the fit and functionality of the printed object. In applications such as prototypes, mechanical parts, or final products, ensuring that the printed dimensions match the intended design is essential for proper assembly and operation. If the dimensions are not accurate, parts may not fit together as intended, leading to potential failures or malfunctions. Inconsistent layer adhesion, surface roughness, and excessive stringing detract from print quality. Inconsistent layer adhesion can result in weak parts, surface roughness can affect the aesthetic and functional properties, and excessive stringing can lead to messy prints with unwanted threads, all of which compromise the overall reliability and performance of the final product. Accurate dimensions, on the other hand, form the foundation of a successful and functional 3D printed item.
