Cherry MX Keycap Guide: DSA, PBT, and Custom 3D Printed Keycaps

Custom keycaps are having a moment—Google Trends shows "keycap set" searches up 50% year-over-year and "custom keycap" climbing 24%. Whether you're into Cherry MX mechanical switches or just want to personalize your keyboard, understanding keycap profiles, materials, and manufacturing methods helps you make the right choice. This guide covers DSA vs PBT vs custom 3D printed keycaps, with practical recommendations for every budget.

Understanding Keycap Profiles

Keycap profiles refer to the shape and height of the keycap. Different profiles affect typing feel, sound, and aesthetics. The three most common profiles you'll encounter are:

Cherry Profile

  • Medium height with a sculpted top
  • The most popular profile for mechanical keyboards
  • Comfortable typing angle with good finger reach
  • Widely available in PBT and ABS materials

DSA Profile

  • Low profile with a spherical top
  • Uniform shape across all rows (not sculpted)
  • Popular for custom and artisan keyboards
  • Great for a sleek, minimalist look

SA Profile

  • Tall profile with a spherical top
  • Sculpted rows for ergonomic typing
  • Retro aesthetic favored by enthusiasts
  • Less common and often more expensive

Keycap Materials: PBT vs ABS

The material your keycaps are made from significantly impacts durability, feel, and sound. Here's what you need to know:

PBT Keycaps

  • Durability: Highly resistant to shine and wear
  • Texture: Matte, textured feel that resists fingerprints
  • Sound: Deeper, thockier sound profile
  • Cost: Moderate to premium pricing
  • Best for: Long-term daily drivers and enthusiasts

ABS Keycaps

  • Durability: Develops shine over time with heavy use
  • Texture: Smooth finish when new
  • Sound: Higher-pitched, clackier sound
  • Cost: Budget-friendly, often included with stock keyboards
  • Best for: Budget builds and those who prefer a lighter sound

Custom 3D Printed Keycaps

3D printed keycaps represent the cutting edge of keyboard customization. With a 3D printer, you can create keycaps in any shape, profile, or design imaginable. This has fueled the growth in "custom keycap" searches, which are up 24% year-over-year.

Building Your First Custom Keycap Set

If you're ready to move beyond stock keycaps, here's how to approach building your first custom set:

Step 1: Choose Your Profile

Start with Cherry profile if you want the most options—it has the widest availability and community support. DSA is great if you want a uniform, low-profile look.

Step 2: Select Your Material

PBT is the recommended choice for most users. It resists shine, feels great, and ages well. If budget is a concern, ABS is perfectly fine for getting started.

Step 3: Consider Custom Accents

Mix and match profiles and materials for a unique look. Many enthusiasts use PBT for the main set and add 3D printed artisan keycaps for the escape key and accent positions.

Step 4: Don't Forget Compatibility

Make sure your keycap set supports your keyboard layout. Key things to check:

  • Number of keys in the set (full vs TKL vs 60%)
  • Stabilizer compatibility (Cherry or Costar)
  • Spacebar sizing (6.25u vs 7u)
  • Accent key compatibility (ISO vs ANSI)

Caring for Your Keycaps

Proper maintenance extends the life of your keycaps and keeps them looking new:

  • Regular cleaning: Remove keycaps monthly and clean with a brush
  • Deep cleaning: Soak PBT keycaps in warm soapy water (avoid hot water for ABS)
  • Avoid direct sunlight: UV can yellow light-colored keycaps over time
  • Use a keycap puller: Never pry keycaps off with sharp tools

Where to Buy Custom Keycaps
