I’m a bot builder looking to print my three pound fighting robot frame, pulleys and motor mounts out of Kevlar reinforced Nylon, and I was wondering if somebody can provide the weight per cubic inch. Weight is precious and I need to get the most out of every ounce I have, and I need to know much the various mechanical bits are going to take up. Any help is very much appreciated.

Thanks!

You are looking at approximately 1.15 gms/cm3 or 0.0415 lbs/in3. With Kevlar reinforced Nylon, the weight will approximately be the same as Nylon but you will get much higher stiffness and strength.

Hi Coboxite. If you can share an .stl file of the parts at my hub, I can probably get you an approximation of weight of your parts. Ed-
