Overview

Randomized trial investigates homogeneous solidification for yielding uniform inter-layer microstructures in 3D aerogels, suggesting improved manufacturing methods.

Key Points

  • The aim is to develop a solidification strategy for freeze-casting-assisted direct ink writing to enhance uniformity in 3D aerogel structures.
  • Utilized computational fluid dynamics modeling to simulate the freezing process.
  • Incorporated moving substrate conditions and constant-temperature thermal boundaries.
  • Analyzed nanocomposite ink properties as functions of temperature and shear rate.
  • Established a process map to identify substrate-temperature pairs for consistent freezing times.
  • Demonstrated effective mitigation of layer-to-layer thermal variations.
  • Achieved reliable printing of aerogels with even inter-layer microstructures.
