Does ABS change color?

The ABS filaments change color at approximately 31°C (88°F). Below 31°C the filaments are one color; above 31°C the filaments are a different color. Therefore, this ABS filament is heat activated. The easiest way to visualize this change is to simply blow a hair dryer on the filament.

Does ABS get shiny?

ABS will get shiny and slick, PBT will not

ABS keycaps will wear with use, causing the surface of the cap to become shinier and slipperier. This shining will cause your keycaps to look inconsistent on the higher use caps. PBT keycaps keep their texture and look for a much longer period of time.
