Which of the following indicates a good quality FDM print?

A good quality FDM print is characterized by the absence of defects throughout the print. This means that the final product should have consistent dimensions, smooth surfaces without blemishes, and a well-defined structure that adheres to the design specifications. When a print is defect-free, it demonstrates that the printing parameters, such as temperature, speed, and material flow, have been optimized effectively, which allows for better strength, appearance, and functionality of the printed object.

In contrast, uneven surfaces, poor layer resolution, and over-extrusion all indicate issues with the printing process that can compromise the quality of the final output. Uneven surfaces may lead to a visually unappealing product, while poor layer resolution can affect the detail and accuracy of the print. Over-extrusion can cause excessive material to be deposited, leading to undesirable shapes and poor finishes. Therefore, the presence of defects or inconsistencies undermines the overall integrity of the print quality, which is why defect-free prints are the hallmark of a high-quality FDM output.
