A new miniature pump — compact, valveless, and operated magnetically — demonstrates the broad capabilities of devices manufactured by 3D printing. Measuring only 1 centimeter in volume, the pump was fabricated in 75 minutes in a single process using multiple materials that cost less than $3.89 per unit. It can move both liquids and gases using less power and experiencing less clogging than standard manufactured pumps of this size. One of the pump designs is the first demonstration of a magnetic, multi-material pump 3D printed monolithically — all in one…
