It would seem that researchers around the world are busy chipping away at anything that causes inconvenience or issue in 3D printing, and especially that of metal as so many industrial components are being made today with that specific class of material. Recently, in Dissolvable Metal Supports for 3D Direct Metal Printing, researchers outlined how they were able to dissolve a temporary support for a stainless steel bridged structure with a 90 degree overhang. The support structure is made with sacrificial metal and low chemical resistance. That the supports can be dissolved offers huge potential for the industry as productivity can be increased exponentially through removing the need for post processing, and less materials need to be used overall.
