Doubleshot vs. Dye Sublimation: Understanding the Differences in Keycap Manufacturing Techniques
ABS (acrylonitrile-butadiene-styrene) and PBT (polybutylene terephthalate) are two types of plastic that are commonly used to make keycaps for mechanical keyboards.
ABS doubleshot keycaps are made by injecting two layers of ABS plastic into a mold, with one layer being the color of the keycap and the other layer being transparent. This allows the keycap to have a more durable, long-lasting design because the legend (the symbol or letter on the keycap) is actually a part of the keycap itself, rather than being printed on top of it. However, ABS keycaps are prone to shine and wear over time, and they can feel slippery to the touch.
PBT dye sublimation keycaps, on the other hand, are made by dyeing the plastic with a sublimation process that infuses the color into the keycap. PBT keycaps are more durable and resistant to shine and wear than ABS keycaps, and they have a slightly rough texture that many people find more comfortable to type on. However, they are typically more expensive than ABS keycaps and may require more force to actuate the keys due to their denser material.
Overall, the choice between ABS and PBT keycaps comes down to personal preference and budget. Both types of keycaps have their own unique characteristics, and both have their own advantages and disadvantages.
