Abstract
(EN)
A 3D printed too! (12, 12a, 14, 14a, 14b) includes at least one tool body (30, 30a, 30b, 130, 130a, 131, 131a) extending between first and second ends (36, 38 136, 138) and including at least one loading surface (54, 54a, 54b, 56, 56a, 56b, 154, 154a, 156, 156a) defining an axis (62, 62a, 62b, 162, 162a), at least one support surface (44, 44a, 44b, 46, 46a, 46b, 144, 144a, 146, 146a) configured to receive a clamp, and at least one predetermined structural weakness (70, 70a, 70b, 170a, 170a) positioned along the axis (62, 62a, 62b, 162, 162a) between the at least one loading surface (54, 54a, 54b, 56, 56a, 56b, 154, 154a, 156, 156a) and the at least one support surface (44, 44a, 44b, 46, 46a, 46b, 144, 144a, 146, 146a). The at least one predetermined structural weakness (70, 70a, 70b, 170a, 170a) is configured to cause the at least one tool body to fail (30, 30a, 30b, 130, 130a, 131, 131a) along a predetermined fault line such that the at least one tool body (30, 30a, 30b, 130, 130a, 131, 131a) splits substantially down a middle of the at least one too! body (30, 30a, 30b, 130, 130a, 131, 131a) when overloaded.

L'invention concerne un outil imprimé en 3D (12, 12a, 14, 14a, 14b) comprenant au moins un corps d'outil (30, 30a, 30b, 130, 130a, 131, 131a) s'étendant entre des première et seconde extrémités (36, 38, 136, 138) et comprenant au moins une surface de chargement (54, 54a, 54b, 56, 56a, 56b, 154, 154a, 156, 156a) définissant un axe (62, 62a, 62b, 162, 162a), au moins une surface de support (44, 44a, 44b, 46, 46a, 46b, 144, 144a, 146, 146a) conçue pour recevoir une pince et au moins une faiblesse structurale prédéterminée (70, 70a, 70b, 170a, 170a) positionnée le long de l'axe (62, 62a, 62b, 162, 162a) entre ladite ou lesdites surfaces de chargement (54, 54a, 54b, 56, 56a, 56b, 154, 154a, 156, 156a) et ladite ou lesdites surfaces de support (44, 44a, 44b, 46, 46a, 46b, 144, 144a, 146, 146a). Ladite ou lesdites faiblesses structurales prédéterminées (70, 70a, 70b, 170a, 170a) sont conçues pour amener ledit ou lesdits corps d'outil à se rompre (30, 30a, 30b, 130, 130a, 131, 131a) le long d'une ligne de défaut prédéterminée de façon telle que ledit ou lesdits corps d'outil (30, 30a, 30b, 130, 130a, 131, 131a) se divisent pratiquement au milieu dudit ou desdits corps d'outil (30, 30a, 30b, 130, 130a, 131, 131a) lorsqu'ils sont en surcharge.
