TEM Kikuchi Sphere Models (HCP)

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)
