At last, a spray powder you don’t need to clean up!
We’re going to let you in on a well-kept secret: regardless of what anybody says, using a coat of spray powder on an object for 3D scanning will always help the process; it’s not always necessary, but it an ideal part of the process. A matte white surface allows for ultimate light detection and leads to optimal, quality 3D scan results. This is especially useful if you are trying to scan clear material, pitch-black objects or shiny metal parts.
Here is an example of a highly challenging object scanned with a peel 2—with and without spray powder:
Part scanned directly, without spraypowder.
Same part scanned with a coat of spray powder.
Actual part for reference.
As shown, the difference is staggering and makes a huge difference on how usable the 3D scanning data is.
Convinced? If so, you might now be wondering what options you have.
These sprays are made of a fine powder that sublimates over time; it stays on for a few hours and progressively disappears to leave the part as clean as it was at the start. This is indeed as neat as it sounds.
Both options work equally well and create a highly suitable matte white coat over the surface. The Cyclododecane Spray tends to be a lumpier, somewhat like a thicker, slightly bumpier coat of frost on your object. The AESUB Spray was very uniform, easy to apply and therefore our favorite.
You can see the magic in action here.
Of course, one of the inconveniences of using a vanishing powder is that it will eventually vanish! If you wish to leave it on for a while so you can scan over a few days for example, you should go for a longer lasting option; in any case, you can always wash it off later.
Our favorite option is Magnaflux SKD-S2, easy to apply it spready evenly on the part and leaved a perfectly uniform layer of white powder. Overall this is the best option if you don’t mind cleaning the part up afterwards; it’s also cheaper.
Another alternative that works very well is simply to use primer; white or grey will work best. Of course, primer is meant to stay on whatever surface you apply it to so there’s no cleaning with option. It should still be a consideration that depends on the situation as it is a mess-free solution and the cheapest option.
Armed with these solutions, you should be able to turn about any challenging material into a true 3D scanning work of art.
