International researchers investigate more complex matters in digital fabrication, detailing their latest study in the recently published ‘ Learning to Accelerate Decomposition for Multi-Directional 3D Printing .’

 .

Delving into a subject of great interest for most users interested in creating complex geometries, the authors explain more about recent work designed to use a beam-guided search algorithm to find an optimized sequence of plane-clipping resulting in the need for ‘tremendously less supports.’ In some cases, no supports may be required at all. A 5-DOF multi-directional 3D printing system that can deposit material along different directions: (left) the printer head can move along x−, y− and z−axes and (right) the working table can rotate around two axes (see the arrows for the illustration of A-axis and C-axis). Planar layers with fixed 3D printing direction usually require supports to prevent collapse; however, this added material can be a source of major hassle […]
