Frequently Asked Questions
What does the HS-GL20P engrave inside?
HS-GL20P is a 355 nm UV subsurface engraver for suitable transparent crystal and glass blanks. It places image points inside the material rather than cutting a surface inscription. Test the blank’s optical quality and internal defects before a production run.
What are the object and engraving size limits?
The listed internal engraving volume is 70 × 70 × 50 mm and the maximum blank size is 150 × 150 × 100 mm. These are different limits: leave enough clear margin around the design within the chosen blank.
Can I use a photo or a 3D model?
The page lists common 2D image formats and GLB for 3D. A photo needs depth mapping or point conversion; a 3D file needs cleanup and scaling. Supply the blank size and desired orientation for a workable layout.
How is HS-GL20P different from surface glass etching?
Subsurface marks are formed inside suitable transparent material, leaving the outer surface largely untouched when the process is set correctly. Choose a surface UV/CO2 system instead when the design must be visible as a surface texture.
What quality checks, warranty and support come with HS-GL20P?
HS-GL20P machines are checked before shipment, including a 48-hour aging test and QC. Free Sample Testing is available when material or mark acceptance needs a physical trial. We provide a one-year warranty on key components. HT Marker provides lifetime technical support for the HS-GL20P. If a fault occurs, send a photo or video, machine serial number and symptom; our engineering team offers remote diagnostics within 24 hours.
How long does HS-GL20P take to ship?
Most HS-GL20P orders are processed and tested within 3–5 business days. Shipping usually takes 5–10 business days depending on destination. We use industrial packaging and can confirm the route and timing for your order.
