Many factors are involved in the process: Lighting, color of the piece, brightness…Here we will
learn how to control them
How can I obtain a good scanning?

Ambient Lighting
Lighting should be uniform, indirect and medium intensity. Thus, the appearance of reflections and
shadows are avoided.

A commendable idea is to set a direct light from the back, with some dispersion and not
concentrated

Object material
Objects with glossy finishes are difficult to scan because they can produce glare. But that does not
mean it is not possible

The next piece is a metal screw. It may seems impossible to scan

But there is the possibility of applying a watercolor or acrylic paint water-soluble covering the
piece and remove all metallic sheen, making it matte

The result of scanning once this part is as follows:

A next step would be the possible re-design of the piece (applying a smoothing with a 3D software
for example)

Another metallic example, which was painted and then scanned:

Object color
The laser beam is red, so that color objects can cause problems when it comes to recognition.

Object color
Light-colored objects can cause problems, especially in high brightness environments. In these
cases it is recommended to decrease the brightness

In the same way that dark objects, the results can be inaccurate, especially in environments with
little light
