“Double-Shot” - this term always dances around you every time you are looking for a set of keycaps to embellish your keyboard. Don’t skip it as you will be surprised with what we are about to reveal right here!

So what are double shot keycaps?

Keep reading! This post will reach all the nooks and crannies of double-shot keycaps from their nature, and why it has become the top choice for discerning users. 

What do double shot keycaps mean?

Before answering “What are double shot keycaps?”, first get clear the term “double-shot”. It refers to the method used to manufacture keycaps for mechanical keyboards.

Unlike standard single-color keycap making, double-shot keycaps are made of two separate layers of plastic, one for the legend and one for the keycap housing.

What are double shot keycaps?
Double-shot keycaps consist of two different layers of plastic
  • Outer shell layer: The first shot forms the outer shell or the keycap's body, which defines the overall shape and look of the keycap.
  • Inner legend layer: The second shot creates the legends that appear on the top surface of the keycap. It is fused together with the outer layer. These legends are "shot" or molded into the keycap to ensure their long-term integration with the keycap's structure.

As you can see, the legend of the double-shot keycap is not on the same layers as the outside layer, instead, they are a separate layer put inside. They are not printed or painted on the top surface to avoid fading or wearing off over time,  keeping the keycaps looking clean and polished.

How double-shot technique came to be?

This two-shot keycap manufacturing method was introduced in the 1970s and 1980s to address the shortcomings of other keycap printing methods such as pad printing or laser etching.

The debut of double-shot keycaps revolutionized the mechanical keyboard industry by offering a balance of longevity and aesthetics. These days, double-shot keycaps have remained a top choice among keyboard enthusiasts in the ever-evolving world of mechanical keyboards.

Alright! We thoroughly explained what are double-shot keycaps. Move to the next part! We will tell you the secret behind this two-tone effect.

How are double-shot keycaps made?

Double-shot keycaps are created through a specialized two-shot molding process. Here's a step-by-step process of how they are made.

Step 1: Design and mold creation

To begin, the manufacturer has to prepare the molds. These are precisely built to create the keycap shape, size and legend design that perfectly fits the keyboard switches.

The mold is then made, with two cavities: one for the main keycap outer shell and one for the legends.

The first shot is typically made of a solid and durable plastic material like ABS or PBT. The second material is usually a different color and is made of a softer, more translucent plastic, often POM or TPR.

Step 2: First shot

The first mold for the outer shell has the missing legend "cut out" at the top. This layer is also thinner than standard keycaps as it will add the legend layer underneath. Keycap manufacturers have different molds for different legends.

Step 3: Second shot

Once the first shot has solidified, the mold is ready for the second shot. The second mold for the legend layer is made to go beneath the first shot and precisely placed into the concave areas on the keycap surface.

This mold is filled with a different colored plastic material, which will form the legends on the keycap's top surface. The legends are physically attached to the main body and ultimately become an inseparable part of the keycap.

Step 4: Cooling and finishing

After ensuring the seamless integration of the legends into the keycap, the mold is cooled to make the keycap material solidify. Once it has hardened, the finished double-shot keycaps can be removed from the mold.

The two-shot molding process allows the two plastic materials to be injected together to produce an all-purpose keycap that fulfills the criteria set forth for durability, aesthetics, and consistency.

Wondering which material is best for your keyboards and fingers feel? Let us make a comprehensive comparison for you to choose the perfect keycap material.

ABS double-shot Keycaps

ABS, often shortly called "acrylic", is the widely used material for keyboard casings and keycaps.

ABS plastic is relatively soft compared to certain plastics but still offers durability and crack resistance. It is praiseworthy for its smooth texture, making it excellent for every pleasant touch during typing sessions.

ABS double-shot keycaps are often cheaper yet less durable than their PBT counterparts which jointly dominate the keycaps market with ABS.

What may let you down about ABS keycaps is that they turn yellow and develop a little greasy or shiny appearance over time as a result of natural oils from the fingertips. Even so, some users still adore it for its unique feel and glossy look.

After all, ABS double-shot keycaps are the best balance between durability and cost-effectiveness. For anyone wishing to spice up their keyboards with eye-catching looks without breaking the bank, ABS double-shot keycaps will be a great deal.

PBT double-shot Keycaps

PBT double-shot keycaps may be the most formidable player, who can usurp all other materials.

This premium material stands out for its exceptional level of toughness, and resistance to abrasion and heat. They can withstand the rigors of intensive typing and gaming sessions without degrading their original texture or legends.

The best feature that makes PBT more long-lasting is that it is more resistant to the acids and oils from your fingers than ABS.

When it comes to feel and texture, PBT double-shot keycaps feel more fulfilling and premium than ABS keycaps. This is due to they have a sandy textured and matte finish that provides excellent grip during typing.

As more high-quality plastic itself, PBT keycaps tend to produce a slightly deeper and more pleasing sound compared to ABS keycaps.

However, given their superior performance, PBT double-shot keycaps often cost you more than those made of other materials.

Choosing between two rivalries: ABS and PBT may always leave you with an uneasy feeling. Then let us clarify through this in-depth comparison between PBT and ABS to help you discover the ace for your keyboard.

PETG double-shot Keycaps

This material might not have received much attention. Yes, PETG is a material that is a little less prevalent for keycaps, but as 3D printing technology develops, you'll see more and more PETG double-shot keycaps.

In terms of aesthetics, PETG double-shot keycaps offer a unique look. The translucent outer layer allows for vibrant RGB lighting to shine through, creating stunning visual effects on backlit keyboards. 

PETG is a kind of thermoplastic polyester that resembles PET (Polyethylene Terephthalate), which is commonly found on water bottles and food containers. PETG has got hallmarks for its clarity, sturdiness, and impact resistance. That's why it is a great input for 3D keycap printing thanks to its ease of use and superb layer adhesion. 

POM double-shot Keycaps

POM, a high-performance engineering thermoplastic, sometimes appears in high-end double-shot keycaps. It is set apart by its outstanding mechanical properties, including high rigidity, low friction, and resistance to heat, chemicals, solvents, and abrasion. These ensure POM double-shot keycaps will not scratch and fade.
