Consumer 3D printing has revolutionized creativity. As creations are designed to complement our day-to-day lives, knowing how to waterproof your prints can become necessary for some applications, such as holding plants.

Several different methods can be used to make a print waterproof¹. This article will focus on altering the extrusion multiplier towards this in a step-by-step guide. It is worth noting that waterproofing does not mean food-safe; that is a topic in itself that will not be discussed in this article.

My printer settings for waterproofing

Printer settings can vary greatly due to operators finding different constellations of values producing quality prints. My settings are listed here as a reference and are for parameters using Simplify3D.

Nozzle diameter: 0.40

Extrusion multiplier: 1.10

Primary layer height: 0.3000
