A simple plants propagation bowl with a practical holder. How to Make a Watertight 3D Print?💧
-
Use PET-G or PCT-G filament: PET-G is perfect for watertight prints due to its excellent layer adhesion and low shrinkage.
-
Increase wall thickness: Use at least 3 perimeters.
-
Lower layer height: Print at 0.1mm-0.2mm layer height for smoother surfaces and fewer micro-gaps.
-
Adjust extrusion settings: Slightly over-extrude by increasing the flow rate by 2-5% to improve layer bonding.
-
Seam alignment: Set seam alignment to random to avoid a continuous line along the same seam, which can cause leaks. If your slicer allows it, try using the Scarf Joint Seam, which overlaps layer transitions, creating a stronger, watertight seal.
-
Seam gap settings: Ensure seam gap settings are tight or set to zero to minimize any gaps at the seam for better watertight integrity.
-
Slow down print speed: Print at 30-50mm/s to allow better control of material flow and prevent gaps.
-
Use 100% infill for the base: If printing a container, solid infill prevents leaks at the bottom.
