Waterproof print test

thingiverse

This model was designed to determine the water-resistance of PETG prints when used for creating complex shapes. It relies on bridging faults created intentionally beneath objects to form openings where liquids may leak in, ultimately allowing these substances to seep out again. With this approach, users can test and experiment with various top-layer settings, such as the number of layers, extrusion widths, and other parameters to optimize their prints' water resistance. Additionally, testing side walls is also crucial as they contribute to overall print waterproofness. A key feature of this item is its compact size (24mm diameter, 37mm tall), making it perfect for rapid printing. The design can be scaled up according to the printer's capabilities with regard to bridging techniques. For more advanced testing purposes, a 'curve' version featuring a truncated sphere at its base instead of a flat bottom is available. This modified model assesses top infill quality alongside curved surfaces and side walls in one go. To utilize this model effectively, users should refer to the included instructions for information on print settings' effects as well as surface tension adjustments. It is recommended to use isopropyl alcohol (as used by the designer) or dishwashing soap dissolved in water to enhance leakage detection and mitigate surface tension issues encountered during testing prints submerged with liquids like tap water.
