MIT is attempting to make a portable 3D printed rotary peristaltic pump for a mass spectrometer. Essentially they’re trying to develop the tricorder. To do this they need a compact and low cost peristaltic pump and in this case they made a rotary one. They 3D printed a Fiberology FiberFlex 40D TPU tube and wrapped it around what is essentially a fidget spinner. The rest of the components were PLA, made on a MakerGear M3-ID modified to run multilateral.  The paper is Compact Peristaltic Vacuum Pumps via Multi-material Extrusion.

Norwegian firm Visitech is a leader in optics for vat polymerization and powder bed fusion. Due to “explosive” growth in the US they’ve expanded their US factory and hope to double revenue by 2025.
