Science封面故事: 快速3D打印技术

2015-03-25 佚名 生物谷

最近著名的《科学》杂志以封面文章的形式报道了革命性的3D打印技术。这种技术在连续的液态界面上利用可调控的光化学反应将3D模型变成一个实物模型,比如封面图片中的埃菲尔铁塔。紫外光可以触发液态树脂发生光聚合反应,然而氧气的存在却会抑制这样的反应。通过在这两者之间寻找一个平衡,研究人员可以从一个液态树脂中生长出一个物件来,相比于传统一层一层的3D打印技术,该打印的速度可以提高25到100倍。 六分

3D打印帮助医生完成高难度连体婴儿分离手术

近日,美国德克萨斯儿童医院由30名外科专家组成的医疗团队花了整整26个小时,通过手术成功分离了一对10个月大的连体双胞胎。ElysseMata是在第19周才发现她怀上的是连体婴儿。12周后,即2014年4月11日,她生下了连体姐妹KnatalyeHope和AdelineFaithMata。 这对双胞胎姐妹的胸壁、肺、心包(心脏的衬里)、膈肌、肝、肠、结肠和骨盆全都连在一起。10个月后
