Best FDM Materials for Outdoor Use

0
1

Hello everyone. I plan to print parts in fused filament deposition for outdoor use, so I need them to be resistant even if they will not undergo any particular load. I thought of materials like ASA or ABS, knowing that I would like the parts to be colored. I also considered the SLS process because the surface quality is still better with fused filament deposition, but I have doubts about the durability of nylon for outdoor applications. Would anyone have advice to give me on the choice of material and why not the technology?

For parts intended for outdoor use, and for fused wire deposition, I recommend ASA. This material is very resistant, both to weather and to sun and aging due to UV rays. And it is available in many different colors. ABS is also a robust material, but its properties are not as good as ASA's when it comes to outdoor conditions. Otherwise, PETG can be a good alternative. It is robust and offers good resistance to UV rays. And it can be found in various colors. As for Nylon, and in particular PA12, it is indeed an excellent material with good mechanical properties, but preferably with SLS technology (or MJF if we stick to powder bed technologies). Associated with fused wire deposition, PA12 is not as resistant.
