What is one example of a medium where plastic prints might be found?

Plastic prints, also known as three-dimensional (3D) prints, can be found in substances that can retain the impression of the object that makes contact with them. In this context, putty serves as an ideal medium for plastic prints because it is a soft, malleable material that can easily capture detailed impressions of fingerprints or other markings when pressure is applied. The characteristics of putty allow for the transfer of unique ridges and patterns, thereby preserving the distinct features of the print.

In contrast, other materials such as glass, paper, and metal do not typically yield plastic prints. Glass and metal surfaces are usually too hard for impressions to be formed effectively, while paper is a flat surface that does not retain three-dimensional impressions. As such, putty stands out as the most suitable medium where plastic prints are likely to be found.
