Area of Science:

  • Materials Science
  • Polymer Science
  • Additive Manufacturing

Background:

  • Controlled deformation of shape memory polymers (SMPs), especially cylindrical ones, presents significant challenges.
  • Existing force application methods lack precision for homogeneous compression of cylinder-like SMP samples.

Purpose of the Study:

  • To develop a material-based solution for controlled deformation of SMPs using four-dimensional (4D) printing.
  • To enable homogeneous compression of cylindrical SMP foam samples through a novel tooling approach.

Main Methods:

  • Utilized fused filament fabrication (FFF) to 4D-print a thermoresponsive tool from polyether urethane (PEU).
  • Employed differential scanning calorimetry (DSC) to determine the glass transition temperature (Tg) of PEU and melting behavior of polyester urethane urea (PEUU).
  • Integrated a laser-cut PEUU foam cylinder within the 4D-printed tool for compression and shape fixing via thermal cycling.

Main Results:

  • The 4D-printed PEU tool successfully compressed the PEUU foam sample upon heating to 75°C, transferring internal stresses.
  • The compressed foam shape was fixed upon cooling to -15°C and maintained its programmed shape for 900 days at 23°C.
  • Reheating to 75°C successfully recovered the original shape of the PEUU foam, demonstrating shape memory recovery.

Conclusions:

  • 4D printing offers a viable material approach to create custom thermoresponsive tools for precise SMP programming.
  • This technique overcomes limitations in deforming cylindrical SMPs, paving the way for complex shape programming.
  • Future applications include diverse 4D-printed tool geometries for programming various SMPs and other programmable materials.
