UV systems still need files
Glass and crystal workflows still begin with customer-photo conversion.
UV vs green laser file prep
Everyone argues UV vs green. The paid job still needs a 3D file.
Wavelength matters. Glass response matters. Machine cost matters. But the customer still sends a flat photo, and that photo still needs depth before it can become a crystal engraving file.

The machine comparison misses the file bottleneck
A better laser does not magically turn a flat portrait into depth.
UV and green lasers can differ in wavelength, source behavior, optics, glass response, software, and shop economics. That comparison matters. But neither machine class automatically turns a customer portrait into usable 3D depth. The shared bottleneck is still photo to 3D engraving file.
Green systems still need files
Established subsurface workflows still depend on usable depth.
Same customer reality
Portraits, pets, memorial images, and gifts arrive as flat photos.
Same flat unlock
Approve final files for 5 credits each after previewing the result.
Workflow
Compare machines, but test the customer photo now.
UV may change the machine/material path, and green may keep an established crystal workflow running. The file-prep sequence stays familiar: photo, generated depth, approved outputs, then machine-specific verification.
Upload the customer photo
Start with JPG, PNG, or WEBP from the actual order.
Generate the 3D depth mesh
Review the generated shape before spending credits.

File and output details
The laser decision and the file decision are different decisions.
UV vs green changes the machine and material workflow: wavelength, focusing behavior, fixture strategy, software import, and settings can all differ. The shared bottleneck is still the customer image. 3DConversions turns the 2D photo into reviewable 3D depth and approved OBJ plus DXF, CAD, and CBF exports for one flat 5-credit unlock.

Caveat
Material behavior, optics, fixtures, software import, power, focus, and calibration remain machine-specific.
Example result
Before the wavelength debate, test the photo.
Preview the generated 3D depth first. If the face, edge, or subject shape is weak, do not unlock final files. If it is ready, approve and continue with the UV or green laser process you trust.

FAQ
UV vs green laser crystal engraving questions.
Is UV better than green for crystal engraving?
It depends on your machine, material, optics, software, fixture, settings, and job type. This page focuses on the shared file-prep problem: turning customer photos into 3D engraving files.
Can 3DConversions tell me which laser to buy?
No. 3DConversions is not a laser vendor. It creates photo-derived 3D file outputs you can inspect before approval.
Do UV and green laser workflows use the same file type?
Not always. File import depends on the machine and software. 3DConversions provides OBJ mesh plus DXF, CAD, and CBF point-cloud exports after approval.
Why mention 355 nm and 532 nm?
Those wavelengths help distinguish common UV and green laser discussions. They do not by themselves determine whether a customer photo is ready to engrave.
What is the safest way to test?
Upload a photo, review the generated 3D depth mesh, and approve only when the result is ready. Uploading, processing, and previewing are free.
How do credits work?
Each approved file uses 5 credits. Free signup includes 25 credits, enough for 5 approved files, and 1 credit = $1 USD. Credits are used only when you approve and unlock final files.
Compare machines, but test the file now
Do not let the UV-vs-green debate delay the next customer file.
Upload one real customer portrait and see whether the 2D-to-3D file problem is solved. Your free account includes 25 credits, enough for 5 approved files.
