Engraving and Finishing Steps
Traditional carving and mechanical engraving shape material by physical contact; laser engraving does the same work with a tightly focused beam of light. Now you learn about laser engraving. Hold your material tight in the machine. Check your settings again. Start the engraving and watch it carefully. Laser engraving makes clear, lasting marks on many things. You can change how deep the engraving goes for different looks. Laser etching is like engraving but makes lighter marks, which is good for soft items.
Keep the area aired out and use a fume extractor if needed. Air assist helps blow away smoke and makes your marks better. When you finish, take out your item and look at it. Clean the engraved part to get rid of dust or dirt. For metal, you might use these finishing steps:
| Technique | Purpose |
|---|---|
| Spray lacquers | Protects from rust and damage |
| Light sanding | Makes sharp edges smooth |
| Black paints/inks | Makes engraved parts darker and easier to see |
| Lacquering/sealing | Adds a layer to protect and make it look nice |
You can also use anodizing or powder coating to stop rust and make your engraving look better. Always test your settings on a sample before you start the main job. This helps you not make mistakes and get the best results.
Laser engraving and laser etching are both clean and good for the environment. These ways use less energy and make less waste than old methods. HeatSign’s laser machines use new technology to give you strong, high-quality marks on all kinds of metals and other things.
