<![CDATA[SoliForum - 3D Printing Community — Mechanical properties of 3D printing polymer]]> https://www.soliforum.com/topic/736/mechanical-properties-of-3d-printing-polymer/ Sat, 08 Dec 2012 16:40:21 +0000 PunBB <![CDATA[Re: Mechanical properties of 3D printing polymer]]> https://www.soliforum.com/post/6658/#p6658 Here is a link to MSDS sheets for the comman ABS and PLA plastics, PA-747 (ABS) and PLA4043D.  This is from Makergear who sells those plastics, as does Protoparadigm.  As far as I know, those are the only filament suppliers who actually disclose what plastics they use, though other might be the same. 

If you know what the actual plastic used in the filament is, it would make it easier to find out the material properties but most of the time we are in the dark.

What are the polymers that are normally used in 3D printers and are their mechanical properties available anywhere?

ABS, PLA: Common
Nylon, HDPE: Less common
