Abstract:
A novel precision grinding tool has been developed for manual-grinding of samples for analysis in a transmission electron microscope. The tool can be self-made by any scientific laboratory with a 3D printer. Using a simple method, the sample can be precisely aligned with the grinding plane, which enables preparation of samples with highly precise parallel faces. Combined with light weight and low vibration, the device is ideally suited for preparing extremely thin samples even below 10 µm thickness. The paper discusses design principles and materials, and the device is evaluated by preparing samples from magnesium alloy and silicon. Design files are included for 3D printing and CNC milling.
