2. Inconsistent Diameter: Inconsistent diameter refers to variations in filament width, which interrupt the flow during printing. This issue can lead to under-extrusion or over-extrusion. Research conducted by J. Wang (2020) found that filaments varying by as little as 0.1 mm can cause significant problems in large prints, affecting accuracy and fidelity.

3. High Likelihood of Jamming: High likelihood of jamming happens when cheap filament clogs the nozzle. This is often due to poor material quality or contamination. Experts suggest regular maintenance and monitoring, particularly with lower-quality filaments, to mitigate this risk (A. Roberts, 2022).

4. Difficulty in Adhesion to Build Plate: Difficulty in adhesion occurs when the filament does not stick well to the print bed. Cheap filaments may require specific temperatures or surfaces, which complicates the printing process. A recent survey by 3D Print Magazine indicates that users often struggle with initial layer adhesion, resulting in failed prints.

5. Increased Chance of Warping: Increased chance of warping happens when the printed object cools unevenly, causing it to lift from the plate. This can occur more frequently with budget filaments, especially when printing larger items or those with flat surfaces.

6. Limited Color and Material Options: Limited color and material options restrict creativity and adaptability in projects. While high-quality filaments are available in a variety of types and colors, cheaper options may only offer a small range, reducing the choices available to users.

7. Poor Strength and Durability: Poor strength and durability means that prints made with cheap filament may break or deform under stress. This is primarily due to lower-grade materials such as recycled plastics being used, which lack the structural integrity of better alternatives (R. Johnson, 2023).

8. Incomplete Melting of Filament: Incomplete melting of filament can lead to blockages or weak spots in the print. This issue often arises from poor heat distribution or inconsistent materials.

9. Variability in Melting Temperature: Variability in melting temperature indicates that the filament may melt at different rates. This can complicate printing settings and affect layer adhesion, leading to structural issues in prints (H. Lee, 2021).

10. Odor During Printing: Odor during printing is common with low-quality filaments, as they may release unpleasant fumes. Many users report discomfort due to the chemical smells emitted when using certain cheaper materials, raising health concerns.

These points illustrate several problems that users may encounter with cheap filament, underscoring the balance between cost and quality in 3D printing.
