Tip of the day
Do you guys want to know how to make your own 3D scanning spray ? great to use on metal parts , easy to clean and not toxic and most important cost almost nothing .
What you will need
- Isopropyl Alcohol.
- Zinc Oxide powder non-nano
- Container for mixing
- Old Spray Bottle or Airbrush Spray Gun, whatever you have available at home
Add the alcohol to the mixing container first, then add half teaspoon of Zinc Oxide powder and mix well until it dissolves and you have milky consistency and color , go slowly , less is better not need to be too dense .
After that you can add the mixture to a simple old spray bottle or airbrush gun for fine results , shake each time and spray from 30 cm a thin layer first and let it dry until the alcohol evaporate , you can use hair dryer to speed the process but go far away with the blow , if needed add another layer , but don’t over spray , your object don’t need to be white
It is great for metal parts and objects that are dark or with shine , it is easy to clean up , no toxic , antibacterial and has a very fine layer . It is touchable after it is dry but not smudge proof
If you want it to be smudge proof in place of alcohol use hair spray , but then you will have to wash your object with water , if you use just alcohol then with a brush you can brush it off easier
this method is great for fine scanning like dental prosthetics and jewelry , it will be very usable with upcoming Revopount MINI scanner for precision scans as regular 3D scanning sprays are too dense for 0.02mm accuracy.
Before and after
you see one layer worked great , the other side without it did not scanned
You can also mix a baby powder with hair spray and use on dark beard or hair for scanning , working better than dry shampoo .
Here is the link to the Zinc Oxide cheapest you can find , I use it for years already .
