Design Talk – Better Flange Design and Printing!


In this episode, we will be at designing flange / adapters and I will be sharing some of my tips and tricks with you as this is one of the most common 3D printed solutions which I create to solve household challenges! Also for most part these are printed in TPU (see more here: perimeters ) as this is a super strong as well as stable thermo-plastic.

Note: After editing the video I realized there a couple of additional points worth adding so, I have included them here in the description:

1. The number of perimeters is a function of the pressure. In the video, I discuss 3 perimeters and this is for static pressure or say just gravity feed water. As you increase pressure, you need to also increase perimeters. So three (3) perimeters is only a starting point, not an end point.

2. Annealing: Geometric transitions can lead to leaks because of gaps in filament adhesion. To address we can “anneal” the part and this does not have to be fancy. We typically use a heat gun to soften the TPU which causes the filament to fill in the gaps.
