Bamboo Fashion in the FabLab: 3D Printed Molds Mimic Bamboo

dorr_moldBamboo is an appealing material for many purposes and worldwide because it is reliable, inexpensive and grows rapidly in varied conditions. As a 2015 Barrett Scholar undergraduate Civil Engineering major Sara Dorr created unique molds using the FabLab’s 3d printers that mimic the internal patterns bamboo fiber. These molds provided opportunities to experiment with novel distributions of materials like carbon fiber. The potential outcome is newly engineered composites that can be used to optimize lightweight energy harvesting structures such as wind turbines.

In bamboo there is a higher density of structural fibers near the stronger exterior surface; this density gradually decreases in fiber concentration moving inward and away from the exterior. This graded pattern is considered to be the critical contributor to bamboo’s remarkable strength in resisting lateral wind loads.

A challenge in many parts of mathematics is that of visualizing structures that live in four dimensions and higher. Such visualizations are crucial for intuition as often important mathematical intricacies do not arise in lower dimensions. In this project, the CEMS UVM FabLab helped Professor Warrington make a 3D print of a four-dimensional hyperplane arrangement called the rank-3 Shi arrangement.

The project was funded by the Office of the Vice President for Research (OVPR) Faculty Activity Network (FAN)
