3D printed items were not made to be indestructible, as they are built with Polylactic acid (PLA) aka plastic. PLA is a thermoplastic polyester that is economically produced from renewable resources. With its low melting point, high strength, low thermal expansion, good layer adhesion, and high heat resistance make it an ideal material for these prints, but still not invincible.
Caution: Not suited for children ages 4 years and under due to small pieces. Not meant for rough play.
