2. Insufficient Layer Adhesion
3. Inadequate Print Settings
4. Neglecting Post-Processing Techniques

To elaborate further:

1. Improper Material Selection: Choosing the right material is critical for waterproof 3D prints. Materials such as PLA and ABS are common; however, they may not offer the required water resistance. For optimal results, consider using materials specifically designed for waterproofing, like PETG or nylon. According to a 2019 study by 3D Print Materials, PETG has superior resistance to moisture compared to standard PLA.

2. Insufficient Layer Adhesion: Waterproofing relies heavily on how well each layer of the print adheres to the others. If the adhesion is weak, gaps can form, allowing water to seep through. It is advisable to ensure adequate nozzle temperature and bed temperature during the printing process to improve layer adhesion. Research from 2021 by Wang et al. shows that optimized temperatures can lead to 30% stronger inter-layer adhesion.

3. Inadequate Print Settings: Print settings such as layer height, infill density, and printing speed play vital roles in the durability of waterproof prints. A layer height that is too large can create visible gaps, and low infill density might compromise structural integrity. For waterproofing, it’s recommended to use a higher infill density, typically around 50% or more. A 2022 analysis by the Journal of Additive Manufacturing found that higher infill percentages significantly reduce the water permeation rate.

4. Neglecting Post-Processing Techniques: Post-processing can significantly enhance the waterproof quality of 3D prints.
