In this edition of 3D Printing News Briefs, we’re starting with research and moving on to software, and then ending with a fun story about a cool DIY print.

 .

LLNL conducted a study about the droplet ejection process in a new metal 3D printing method. FreeCAD has directly integrated the 3DfindIT.com visual search engine by CADENAS. Finally, a maker used 3D printing to build a bartop arcade cabinet that’s entirely powered by Raspberry Pi. LLNL Simulates Droplet Dynamics in Metal 3D Printing A comparison between the experimentally observed ejected droplet shape at break-up (a) and the simulated droplet shape (b) at various operating conditions approaching the experimental conditions. The simulated droplet shape significantly differs from experiments, highlighting the fact that essential physics appear to be missing from the model. Image courtesy of Andy Pascall/LLNL. A team of scientists from Lawrence Livermore National Laboratory ( LLNL ) published a research paper about the dynamics of droplet ejection that could help advance 3D printing. The researchers simulated the ejection process and breakup dynamics of droplets in a novel AM process called Liquid Metal Jetting, or LMJ, which jets molten droplets of liquid metal from a nozzle to 3D print parts without […]
