Open Source Nutating Mixer

thingiverse

Scientists and researchers have developed a 3-D printable, open source desktop nutating mixer that provides a fixed 20° platform tilt angle for gentle three-dimensional agitation of chemical or biological samples without foam formation. Custom components for the nutating mixer are designed using free OpenCAD software to enable customization. All non-readily available components can be fabricated with a low-cost RepRap 3-D printer using an open source software tool chain from common thermoplastics. Designs are open sourced and can be configured to add more functionality in the future. The device is easy to assemble, accessible to both science education for younger students and state-of-the-art research laboratories. Overall, the open source nutating mixer can be fabricated with US$37 in parts, which is 1/10th of the cost of proprietary mixers with similar capabilities. The open source nature of the device allows it to be easily repaired or upgraded with digital files, as well as accommodate custom sample sizes and mixing velocities at minimal additional costs.
