PP is the more flexible, fatigue-resistant option, while POM provides the stiffer and more dimensionally stable sliding surface. POM is usually the stronger starting point for precision bushings, gears, rollers, and guides, but it is… 

PP handles repeated bending and wet environments with less property drift, while Nylon is usually the stronger choice for loaded joints, gears, bushings, and wear-prone functional parts. The decision is not simply flexibility versus strength:… 

PP is lighter, more chemically resistant, and far better suited to repeated living-hinge movement, while PETG is easier to print with lower warping and more predictable dimensional accuracy. The practical choice depends on whether the…
