Frequently Asked Questions

What exactly is a "Depth Map" or Grayscale image?

A depth map is a 2D black-and-white image where the shades of gray represent physical depth. Black means “carve deep,” and white means “leave the surface raised.” Our LaserEmboss software automatically reads these shades to create a stunning 3D relief. You don’t need to know how to build complex 3D models.

Can the HS-FLD series engrave hard metals like Titanium and Damascus steel?

Absolutely. While traditional CNC micro-milling struggles with tool wear and snapped bits on hard materials, our fiber lasers (especially the HS-FL60D with output power 60W) vaporize titanium, stainless steel, and Damascus effortlessly, leaving razor-sharp edges and clean bottoms.

Which wattage should I choose: 20W, 35W, or 60W?

It depends on your production speed and the materials you use.

  • 20W: Perfect for hobbyists working mainly with softer metals like brass, copper, and silver.
  • 35W: The sweet spot for everyday EDC gear and stainless steel.
  • 60W: The “Production Beast.” It offers the fastest material removal and highest peak power for deep, burn-free engraving on hard titanium and custom coin dies.

How does the Motorized Z-Axis Auto-Compensation work?

When engraving deep 2.5D relief, the focal point changes as the laser removes layers of metal. Instead of you manually cranking a wheel, our motorized Z-axis automatically lowers the laser head by micro-millimeters as it carves deeper. This ensures perfect focus and crisp details on every single pass.

Do I need to learn complex software like ZBrush or AutoCAD?

Zero 3D CAD experience is required! If you can import a photo, you can use this machine. The included EZCAD2 and LaserEmboss software handle the complex layer-slicing automatically.

How deep can the laser actually engrave?

You can achieve highly tactile, deep 2.5D relief ranging from 1mm to 2mm deep (or more, depending on the material and the number of passes). It is perfect for creating deep-textured knife scales, dimensional Zippo cases, and steel dies for pressing custom coins.

Can I use this machine to cut metal blanks?

While the HS-FLD series can cut through thin gauge metals (like thin brass or silver sheets for pendants) using multiple high-power passes, it is primarily engineered for high-precision deep engraving and 3D surface relief, not as a dedicated sheet metal cutter.

What if I don't have my own relief designs yet?

You can start profiting on day one! Every HS-FLD machine includes an exclusive free library of premium grayscale depth maps, we also can suggest AI tool to make depth map photo. Just load a design into the software, press start, and watch your laser create a masterpiece.

Stop leaving money on the table. Upgrade to true 2.5D deep relief today.

Send us your toughest Grayscale Depth Map, and our engineers will engrave it on brass, steel, or titanium for free. We’ll send you an HD video of the process and macro photos of the finished piece. Zero risk, zero obligation.
