+# Materials
+
+bss's random thoughts and notes on 3D printing materials.
+
+## Bambu Lab PLA
+
+### Basic
+
+* In general, nice texture, but under direct light, you can see a bit of the infill pattern through the walls. Not super
+  distracting, but it's there.
+
+#### White
+
+* Walls are practically translucent, you can almost always see the infill. Do not use for major components.
+* Looks perfectly good for thin things like the Neutrik plates, decorative pieces, that kind of thing.
+
+### Matte
+
+* I don't like the texture as much, but they do produce nice non-primary color colorways, and you don't see the infill.
+* Seems like their plastic treatment leaves some plate residue, so be better about cleaning it or you'll get ghosts.
+
+## Hatchbox PLA
+
+* Haven't done a lot of this yet, but my wife really likes the blue.
