We took a look at some of the strongest 3D printing materials, focusing on filaments for FDM, to see how they differ and ...

The downside is that objects printed in PLA tend to be somewhat brittle and have a low heat tolerance ... capable of working with. Industrial 3D printers like the Apium P220 start at $30,000.
