Advanced Topological Design for Vibration Dampening in Cryogenic TEM Systems Using Lattice Structures and Additive Manufacturing
Cryogenic transmission electron microscopy (Cryo-
TEM) requires precise control of vibration
dampening to maintain imaging quality, particularly
in the 20-50 Hz frequency range. Conventional
vibration dampening approaches often struggle
with achieving the required precision and
adaptability for such specialized equipment. This
project focuses on the topological optimization of
vibration dampening components using lattice
structures, advanced CAD tools (e.g., Fusion360),
and AI-based design methodologies, validated through Laser Powder Bed Fusion (L-PBF)
manufacturing.
This project aims to deliver a validated framework for designing and manufacturing
advanced vibration-dampening components for Cryo-TEM systems, enabling enhanced
performance and reliability.

Key aspects include:
• Designing lattice structures optimized for vibration dampening in the 20-50 Hz range.
• Investigating the impact of material selection (steel and magnesium) on dampening
performance.
• Exploring the effect of magnesium infiltration into lattice structures.
• Prototyping with a shell design containing loose L-PBF powder for enhanced
vibration isolation.
• Comparing these approaches using Finite Element Analysis (FEA), manufacturing
prototypes, and experimental testing.
