Watertight 3d Model. Air tight and water tight containers such as cups canisters or tanks can now be 3d printed using standard filament 3d printers. Why do watertight solid models matter.
Watertight gives us the ability to store important historical data about the customer s products services as well as the type of relationship that we have had with them over the years. Solid models enable mass properties calculations are critical for 3d printing and finite element analysis and are preferable for machining. From the icon of those two choices you can tell that the watertight model is intended for 3d printing and unwatertight model is more for future editing.
Lab ware such as tubing pipettes measuring spoons and cups and beakers and flasks can also be made.
Most normal 3d prints are not watertight. A non watertight model will generate a problematic stl file when converted. How do you make a group of surfaces into a watertight solid. For most cases this is true.
