UV 3D Crystal Laser Engraving Machine — Inside and Surface

Built for small crystal gifts and mixed-material orders. It engraves portraits, logos, and 3D designs inside crystal, then adds names, dates, or fine details on the surface — without buying a separate surface-marking machine.

Two Engraving Modes

Engrave inside crystal, or mark the surface

Use it for 3D inner engraving in crystal, then switch to surface marking for names, logos, patterns, and fine details.

Mode 1

3D crystal inner engraving

The beam passes through the outer face and releases its energy at the focal point inside the crystal, forming fine points that build the image. Nothing is cut on the outside.

  • Up to 60 × 60 × 70 mm
  • K9 crystal and optical glass
  • Outer surface stays clear and untouched
Mode 2

Surface marking & engraving

Move the focus to the surface instead, and the same laser creates text, logos, frosted patterns, and identification marks on the outside of the piece.

  • Crystal, glass, acrylic, plastic, and coated surfaces
  • Fine text, logos, patterns, serial numbers
  • Send your material — we'll test it before you order
UV or Green Laser?

Which machine fits your products?

We build both. The right one depends on your crystal size, the materials you work with, and how much you produce.

UV laser — 355 nm (this machine)Green laser — 532 nm

The UV model is a good fit when…

  • You mainly produce keychains, photo blocks, small awards, and souvenirs
  • You need both crystal inner engraving and surface marking
  • You also take orders for acrylic, plastic, glass, or coated materials
  • You're starting a personalized gift line and want a compact machine

How It Works

From a file to a finished piece

01

Prepare the file

Import your photo, logo, text, or 3D design into the software. DXF, STL, OBJ, and BMP are supported.

02

Place the workpiece

Set the crystal or part on the table, or in a suitable fixture, and use the positioning function to check the centre.

03

Preview and set up

Choose inner engraving or surface marking, then use the red light to check the position and working area.

04

Start the job

Confirm the layout and settings, then begin. Time per piece depends on the material, size, and level of detail.

Why a red-light preview? The 355 nm UV beam is invisible. The red light gives the operator a visible reference for the position and working area before engraving starts.
Specs & FAQ

Choose the right configuration

Three power options, two cooling methods. Here's what separates them.

10 W
Water-cooled

Chosen when more laser power or longer daily operation is needed. A matching chiller is included.

15 W
Water-cooled

The highest power in the series, for more demanding workloads. Also supplied with a chiller.

Only the 5W is air-cooled. The 10W and 15W use water cooling to hold a stable laser operating temperature. Actual speed and engraving effect depend on the material, design, and settings — send us your material, product size, and expected daily output and we'll recommend the configuration.

Frequently Asked
Which power should I choose?

The 5W suits a compact, air-cooled setup with lighter daily work. The 10W and 15W are usually chosen for heavier workloads or longer daily operation, and come with a chiller. Which one fits depends on your material, engraving size, and expected output — tell us those and we'll advise.

Does it need a water chiller?

The 5W is air-cooled and needs no external chiller. The 10W and 15W are water-cooled and are supplied with a matching chiller, which holds the laser at a stable operating temperature.

What's the maximum inner engraving area?

60 × 60 × 70 mm. That covers small crystal blocks, keychains, souvenirs, photo gifts, and small awards. For larger pieces, our green industrial model goes up to 300 × 400 × 130 mm.

Can it work on materials other than crystal?

Inner engraving is for K9 crystal and optical glass. Surface marking can also be done on glass, acrylic, selected plastics, and coated materials. Different materials react differently to a UV laser, so we recommend sending a sample for testing before you order.

What files can I use?

DXF for vector artwork, STL and OBJ for 3D models, and BMP for images. Photos, logos, text, and 3D designs each need their own preparation before engraving — send us your file and we'll tell you what it needs.

What type of crystal gives the best result?

K9 optical crystal, for its clarity and consistency. Results on ordinary glass depend on its composition and optical quality — send a piece and we'll test it.

Do you provide training and sample testing?

Yes. We test your material or design before you order and send photos and video of the result. Operation guidance, software training, and online technical support come with the machine.

After You Buy

Bought from overseas, still looked after

A factory behind the machine — not a reseller. Here's what you get.

Tested before shippingEach machine completes an engraving test and a full function check before it leaves the factory. We can send you photos or video of that test before it ships.
Training and operation supportOperation guidance, software training, manuals, and video support. Remote assistance when you need a hand with a job.
Reply within one working dayMessage us on WhatsApp and a real person answers — setup, software, parameters, and operation help over video.
1-year warranty on the whole machineNot just the laser — the complete machine, subject to the warranty terms (consumable parts excluded). Replacement parts ship direct from our factory by international courier.
Sample Testing Before You Order

See the result on your own material before ordering

Send us your photo, design, or a piece of your material, with the size and the effect you need. We'll run it on this machine and send you photos and video of the result.
