UV lasers can mark almost any surface, but the feature that really makes them stand out is the ability to engrave inside glass and crystal. In this video I walk through the full process of turning a photo of a person into a crystal engraving using a UV laser — the kind of floating 3D crystal photo you see sold as memorial keepsakes, wedding gifts, pet tributes, and personalised glass blocks.

If you’ve been searching for how to put a photo of a person into a crystal, how to engrave a person inside glass, how to make a 3D crystal engraving from a photo, or how to convert a picture of a person into a 3D crystal model for laser engraving, this guide breaks down exactly how it works.

Because here’s the truth: you don’t actually want a traditional 3D sculpt.

Most people searching for “3D crystal photo of a person” or “convert photo to 3D crystal engraving” are really looking for a point cloud depth conversion — a layered internal engraving that creates the illusion of a floating 3D person inside a crystal block. I show the difference between using a real 3D model versus generating a depth-based render from a 2D image, and why many built-in UV laser tools produce low-detail, ghostly results that don’t look professional when lit.

From there, I cover the full workflow using Cockpit 3D and Fastpass to generate high-detail inner crystal engravings. That includes uploading your image, background removal, improving older or low-resolution photos of a person, enhancing memorial images, adjusting depth, controlling resolution, exporting correctly, and importing into UV laser software without breaking dot spacing.

Whether you’re using the xTool F2 Ultra UV or another modern UV laser that supports GB or STL files, the process applies. We go through crystal block preparation, lens selection, cleaning tips, matching Z layer height to resolution, avoiding voxelation, and choosing the correct inner engraving settings so your person inside the crystal looks clean, sharp, and properly lit — not like a horror movie under-lighting experiment.

This tutorial covers:

– How to engrave a photo of a person inside a crystal
– How to put a person inside glass using a UV laser
– How to convert a 2D photo of a person into a 3D crystal engraving
– How point cloud crystal engraving actually works
– How to make memorial crystals of a loved one
– How to engrave pets, couples, families, and groups inside glass blocks
– How to prepare files for inner laser engraving
– How to avoid common mistakes when resizing crystal files

We also break down the real costs of producing a laser engraved crystal photo block. That includes Fastpass credit pricing, crystal block sourcing, discounts when buying in bulk, and what your raw per-unit cost looks like if you’re making and selling 3D crystal engravings as a business.

If you’re looking at UV laser crystal engraving as a side hustle, small business, Etsy product, funeral home partnership, pet memorial service, or live market stall offering, I run the numbers on what it costs to turn a photo of a person into a crystal and what these typically sell for online.

This isn’t just about making something that works. It’s about producing professional-looking crystal engravings of a person that light correctly, hold detail, and are genuinely good enough to sell.

If you’ve ever wondered how people create those floating 3D photo crystals on Etsy or Amazon, or how to laser engrave a person inside glass using a UV laser, this is the full process from image upload to finished polished crystal block.
