项目摘要

This Research Tools and Instruments (RTI) proposal aims at establishing a novel and customized in-house additive manufacturing (AM) workstation. This critical workstation will allow us to fabricate anatomically-shaped soft tissues/implants, wearable devices and prostheses with heterogeneous internal properties/architectures such as variable density, variable soft materials, conformal channels and varying porosity. The requested components of this novel workstation will establish a critical platform, enabling the group to remove several major obstacles hindering the development of the abovementioned devices. This highly needed setup will add a new dimension to the fabrication of anatomically-shaped soft medical devices by enabling the following capabilities: (i) incorporation of different polymers and soft bio-materials across structures with different viscosities, (ii) creation of conformal passages, (iii) creation of controlled, pre-determined density distributions in desired orientations, (iv) selective injection of polymeric elements on planar and non-planar surfaces, and (v ) insertion of a sacrificial porogen material to control the level of macro-porosity in desired regions of the structures.

该研究工具和仪器（RTI）提案旨在建立一个新颖的和定制的内部增材制造（AM）工作站。这个关键的工作站将使我们能够制造解剖形状的软组织/植入物，可穿戴设备和假体与异质内部属性/架构，如可变密度，可变软材料，适形通道和不同的孔隙率。这一新型工作站所要求的组件将建立一个关键平台，使该小组能够消除阻碍上述设备开发的几个主要障碍。这种高度需要的设置将通过实现以下功能为解剖形状的软医疗器械的制造添加新的维度：（i）在具有不同粘度的结构上掺入不同的聚合物和软生物材料，（ii）产生共形通道，（iii）产生在期望取向上的受控的、预定的密度分布，（iv）在平面和非平面表面上选择性注入聚合物元素，和（v）插入牺牲成孔剂材料以控制结构的所需区域中的大孔隙度水平。
