@ -32,4 +32,13 @@ There are 3 primary categories of PLA alloys:
1. "Tough" PLA
Tough PLA is created by combining PLA with polybutylene terephthalate, or PBT. PBT is commonly used in keycaps for keyboards.
Tough PLA prints and acts similarly to PLA, but it has higher temp
Tough PLA prints and acts similarly to PLA, but it has higher temp and impact resistance, and it's less brittle. This is largely an upgrade to PLA with no real drawbacks.
2. "Matte" PLA
Matte PLA is created by combining PLA with a plant based additive.
Matte PLA has a higher impact and shatter resistance than regular PLA, but it absorbs humidity more easily and is more likely to jam in an extruder during printing. This is largely a side-grade to regular PLA, it makes a slightly different set of tradeoffs.
3. "High speed" PLA
High speed PLA has a lower melting temperature and a reduced viscosity, greatly increasing the speed at which it can be printed at.
