Ninja Flex is a highly flexible polyurethane based filament ideal for direct-drive extruders such as Ultimakers. Using this material could simplify the production of soft actuators significantly and speed up the process.
We will be investigating the properties of this material, the optimal method of printing it and the possible applications in the field of Soft Robotics. Especially for Soft Robotics it is desirable to create an airtight actuator to gain maximal control of the movements, when pressure is applied. To do so we will experiment with a lot of different printer settings and log our results in this blog.
