Beschreibung
Zusammenfassung:	In accordance with aspects of the invention, provided herein are resins that: (a) are suitable for use in additive manufacturing techniques such as bottom-up and top-down stereolithography, (b) produce bioabsorbable articles, and (c) produce flexible or resilient articles (preferably at least at typical room temperature of 25 DEG C, and in some embodiments at typical body temperatures of 37 DEG C). Such resins may include: (a) a bioabsorbable polyester oligomer having reactive end groups; (b) a non-reactive diluent; (c) optionally, a reactive diluent; and (d) a photoinitiator. 根据本发明的各方面，本文提供了树脂，所述树脂：(a)适用于增材制造技术诸如自下而上和自上而下的立体光刻术，(b)生产生物可吸收性物品，和(c)生产柔性或弹性(优选地至少在25℃的典型室温下，并且在一些实施方案中在37℃的典型人体温度下)物品。此类树脂可包括：(a)具有反应性端基的生物可吸收性聚酯低聚物；(b)非反应性稀释剂；(c)任选的反应性稀释剂；和(d)光引发剂。
