Best Practices For Engraving Keycaps
Choose the Right Keycap Material
Keycaps are made from different materials, and not all are suitable for engraving.
- PBT Keycaps – Best for laser and CNC engraving due to their durability.
- ABS Keycaps – Can be engraved but prone to melting if high heat is applied.
- Metal Keycaps – Ideal for CNC or chemical etching but require specialized tools.
Use a Guide or Template
If using a manual engraving tool, stencil guides or templates help ensure precision and uniformity in your design.
Secure the Keycap Before Engraving
Using a vise or clamp to hold the keycap in place prevents movement and ensures more accurate engraving.
Test on Scrap Keycaps First
Before engraving your primary keycaps, practice on spare keycaps to perfect your technique and tool settings.
Work in a Well-Ventilated Area
Engraving plastics can produce fumes, so ensure proper ventilation, especially when using a laser engraver or chemical etching.
Post-Engraving Finishing Touches
After engraving, enhance the design with:
- Acrylic Paint – Fills the engravings for a colored effect.
- UV Resin – Seals the engraving for a glossy finish.
- Sandpaper (Fine Grit) – Smoothens rough edges.
Conclusion
Engraving keycaps is an excellent way to personalize your keyboard and enhance its aesthetics. Whether you choose laser engraving, a Dremel tool, CNC engraving, or chemical etching, selecting the right tools and following best practices will ensure high-quality results. Experiment with different methods and unleash your creativity to craft a one-of-a-kind keyboard that reflects your unique style.
