[quote=ctcataman]I print lots of parts for work, surgical instruments prototypes. More importantly I break lots of them. Be sure the slicer makes them solid. PLA isnt very strong. Its strength is about 16% of the most common aluminum. Use in steering parts should be avoided.
Parts break between the layers, which are weld lines.
The PLA parts feel good when new, and for a few cycles match the load capacity of conventional materials. Then they fall apart.
There are filled materials that are much stronger, some carbon filled. They didnt print well on our machines so I cant talk to their capacity.
I would recommend use in non critical parts only.[/quote]
