    Hi,

    For whoever needs it, I compiled some 3D material densities to add to the materials custom libraries:

    ;; 3D printing plastics
    ;;
    *ABS,1.04,grams,centimeter,Plastic,Plastic
    *ASA,1.05,grams,centimeter,Plastic,Plastic
    *CARBON-FIBER,1.3,grams,centimeter,Plastic,Plastic
    *HIPS,1.03,grams,centimeter,Plastic,Plastic
    *NYLON,1.52,grams,centimeter,Plastic,Plastic
    *PETG,1.27,grams,centimeter,Plastic,Plastic

    Hi Berthold -- (1) The "measures" used in the definition are irrelevant as the volumes, masses, and CG positions are calculated in your defined units of measure. (2) I do not use 3D Printing because of the bad data distributed by the materials' manufacturers. I spent no small amount of time cross-checking them for the USAF and NASA a few years ago and the "published data" can be best describes as fiction.

    Standard molding ABS has a finished density of .0375 lbm/in³. Nylons range from .0397 to .049 (lbm/in³) ranging from Nylon 612 to Nylon 66 20% MoS2 filled. .05 lbm/in³ is a reasonable (average) for such materials. And yes, I think in lbs & inches. -- Lew

    Hi Lew,

    Those values seem quite close . 0.0375 lbm/in³ = 1,038 g/cm^3 as opposed to 1,04 g/cm^3 that was referenced in the online document.
    I made the list mainly, because I needed PETG which is what I mostly print with and SUPRAX glass.
