I am starting to hate PLA.
PETG was in the last month my material of choice, so far I can only see two minor drawbacks for me: You need to construct your parts thicker to achieve the same stiffness and cutted threads are quite weak (so using a integrated nut is mostly better for threads which need to hold bigger forces).
Another thing is the avaibility of colors, especially metallic looking (like copper, gold etc) colors are rare. And that lead me to use a PLA again, for a project (https://github.com/callimero/KrystaLED) I wated a nice looking material and used 3DK.berlin Copper (color, not filled) PLA which really looks fantastic.
However my overhangs looked terrible (of course I use my PLA slic3r settings :-)) and my (maybe poorly) constructed battery door snapper either did not print at all (curling and the snap from my buildplate) or did break while using. The layer adhesion seems to be too weak (compared to PETG where I did not manage to break that part) and I can’t construct it any thinner to make it more flexible.
I did try some other PLA I have around but no cigar.
Suggestions welcome, but so far I will stay withe PETG. Or maybe print the case in PLA but the battery door in PETG.
