Defoaming high-transparency silicone for 3D printers
We produce artificial silicone organs and blood vessels with a 3D printer, and use them for our research on blood flow in actual organs to improve surgical precision. It is necessary to make them out of high-transparency silicone so that the internal structures can be seen clearly.
We used to put silicone intended for 3D printers in a vacuum chamber to defoam. However, this task required a lot of time because silicone tended to overflow in the vacuum chamber. We therefore were looking for a new approach to address this issue.
We also had the problem that when the artificial organs we produced were evaluated or observed, laser light diffused inside the organs, significantly reducing measurement accuracy and making it difficult to carry out objective evaluations.
