Open Source Nutating Mixer

myminifactory

Users can create their own open source desktop nutating mixer with a fixed 20° platform tilt angle, providing gentle three-dimensional agitation of chemical or biological samples without foam formation. The custom components for the nutating mixer are designed using FreeCAD software to enable customization and modification. All non-readily available components can be fabricated with a low-cost RepRap 3-D printer using an open source tool chain from common thermoplastics. Users have access to all designs, which can be configured to add more functionality in the future. Assembling this device is relatively simple and accessible to both science students and researchers. The total cost of fabrication is just US$37, a fraction of what proprietary nutating mixers with similar capabilities would cost. This open source device can be easily repaired or upgraded using digital files, as well as accommodate custom sample sizes and mixing velocities at minimal additional costs.
