We describe rheological protocols to study layered and three-dimensional (3D)-printed gels. Our methods allow us to measure the properties at different depths and determine the contribution of each layer to the resulting combined properties of the gels. We show that there are differences when using different measuring systems for rheological measurement, which directly affects the resulting properties being measured. These methods allow us to measure the gel properties after printing, rather than having to rely on the assumption that there is no change in properties from a preprinted gel. We show that the rheological properties of fluorenylmethoxycarbonyl-diphenylalanine (FmocFF) gels are heavily influenced by the printing process.
我们描述了用于研究分层和三维（3D）打印凝胶的流变学方案。我们的方法使我们能够在不同深度测量性质，并确定每层对凝胶的组合性质的贡献。我们表明，在使用不同的测量系统进行流变学测量时，会存在差异，这直接影响正在测量的结果性质。这些方法使我们能够在打印后测量凝胶的性质，而不必依赖于假设预打印凝胶的性质不会发生变化。我们表明，芴甲氧羰基-二苯丙氨酸（FmocFF）凝胶的流变性质受到打印过程的严重影响。
