Here is a good table of mechanical properties of 3D printable materials. PLS actual comes out as very good, except for durability because of its typical failure mode, it breaks rather than deforms.
https://www.simplify3d.com/support/materials-guide/properties-table/ I'll still repeat that good design is FAR more important than selecting some magic materials. A redesign can many times net a 10x or more improvement but swapping materials can only get an incremental increase. Going back to the question, If the goal is dimensional stability, the best solid un-filled plastic is PLA, the stiffest is carbon-filled PLA but the carbon stuff is not as strong and dose not save weight. over plain PLA. If you want a "tough" plastic that does not shatter then you want something flexible. But that was nt the question asked here. My walking robot is made from PLA and motors with hardened steel gears. The biggest design issue I'm having is the gears are wearing out too soon. But large gears are over my budget On Mon, Oct 10, 2022 at 7:37 AM gene heskett <ghesk...@shentel.net> wrote: > On 10/10/22 07:38, andy pugh wrote: > > On Sun, 9 Oct 2022 at 11:10, Nicklas SB Karlsson <n...@nksb.eu> wrote: > >> Polyoxymethylene (POM) https://en.wikipedia.org/wiki/Polyoxymethylene ? > > I have a reel of POM filament.
