These 3D models represent the three-dimensional Kikuchi bands observed in hexagonal (HCP) materials in transmission electron microscopy. Intended both for education and as a visualisation aid, they include all principal basal, prismatic and pyramidal bands (modelled using the lattice parameters for alpha-zirconium). The versions included are; A 'solid' opaque version (with a void in the centre for reduced material cost) A 'hollow' skeletonised version (with a hexagonal prism suspended at the centre, to represent the HCP unit cell). These have been test-printed on a Bambu Labs A1 Mini 3d printer, using PLA through a stainless steel 0.4mm nozzle. The extrusion setting is '0.08mm Extra Fine' as per the specifications in Bambu Studio. Print settings (Solid): Recommended infill: 5-10% (gyroid) Wall thickness: 5 loops Supports?
