How to Engrave 3D Coins for Beginners! | Complete Laser Guide!
Final Optimized Description
Ever wondered how to get that deep, professional 3D relief on a brass coin? In this video, I’ll walk you through the complete process—from start to finish—using an ACMER 100W MOPA fiber laser.
This beginner-friendly guide is designed to help you understand 3D engraving without the guesswork. We’ll cover how LightBurn interprets depth maps (grayscale images), how to choose the right bas-relief artwork, and how to dial in your setup for consistent, high-quality results. I’ll also share my exact LightBurn settings, along with my finishing process using Brass Black and Renaissance Wax to achieve that antique, professional look.
In this video, you’ll learn:
🧠 Depth Maps Explained — How grayscale controls engraving depth
🎯 Image Selection — Why bas-relief images with minimal shading work best
🛠️ Hardware Setup — Using an XY table and coin jig for precise alignment
⚙️ LightBurn Settings — My setup for a 100W MOPA fiber laser
