Tensile Strength of 3D Printing Plastics

Basics

• Polycarbonate appears to be the strongest - 10000 PSI - [1]
• IC3D boasts of 14000 psi reinforced nylon - [2] - but at $160/kg [3], it is 3x that of PC filament - [4].
• How about adding powdered glass fibers to filament for extra srength? [5] - sounds like that prevents shrinking.
• polycarbonate works as well as fiber-reinforced Nylon X and continuous fiber printed other material - [6]
• Nylon X has 14000 PSI strength - [file:///home/ose/Desktop/MatterHackers%20NylonX%20TDS%20(1).pdf]
