摘要
介绍了基于微立体光刻技术制造的三维支架初步模型.由微立体光刻设备制备出了μm级的圆柱阵列式支架和三角孔式支架,整体结构很微小,结构上端为原生代细胞附着区域,下端是细胞培养液的贮液池.支架结构精度较高,可以达到传统快速成型技术不能具备的等级,其微孔之间的孔隙结构达到200μm左右,同时,微孔的数量、大小、分布及形状可人工影响或控制.
This paper presents the principium model of the three-dimension bracket made by micro-solid light chisel technology.The bracket is the structure that arrays of round-column holes,upper end of which is proterozoic cells accrete field,the bottom of which is the store-pool of the foster liquid.Precision level of bracket is higher than that the traditional rapid prototype(RP) technology attached,the distance among the holes is about 200 μm,at the same time,the amount,the size,the distributing and the shape of t...
