Beschreibung
Zusammenfassung:	Provided herein according to some embodiments is a polymerizable liquid useful for the production of an energy absorbing three-dimensional object comprising polyurethane, polyurea, or a copolymer thereof by additive manufacturing. The polymerizable liquid may include components having soft segments (e.g., polyol/polyamine midblocks, chain extenders) of different number average molecular weights. Selon certains modes de réalisation, l'invention concerne un liquide polymérisable utile pour la production d'un objet tridimensionnel absorbant de l'énergie comprenant du polyuréthane, de la polyurée ou un copolymère associé par fabrication additive. Le liquide polymérisable peut comprendre des constituants ayant des segments souples (par exemple, des blocs médians de polyol/polyamine, des allongeurs de chaîne) de différentes masses moléculaires moyennes en nombre.
