Figure I: Comparison of the deformation and color change of radially aggregated and folded biopolymer prints aged over 1 year with different 2-dimensional geometries and 3-dimensional forms.
Figure II: A series of bilaterally symmetric prints are composed of a pectin chitosan infill base layer with a cellulose lattice surface layer. The cellulose surface layer is generated to align to specific vectors that encourage creasing the surfaces along predefined ridges. Two sets of 3 identical prints are clamped along the wetted central pectin spine to adhere all surfaces together.
Figure III: The cellulose surface layer is generated to align to specific vectors that encourage creasing the surfaces along predefined ridges.The center lines of each print have a region of pectin infill printed above the cellulose lattice. Regularly spaced holes on the print allow the surfaces to be clamped and joined together.

These experiments examine how radially aggregated and folded biopolymer surfaces may deform over time. A series of bilaterally symmetric prints are composed of a pectin chitosan infill base layer with a cellulose lattice surface layer. The cellulose surface layer is generated to align to specific vectors that encourage creasing the surfaces along predefined ridges. The center lines of each print have a region of pectin infill printed above the cellulose lattice. Regularly spaced holes on the print allow the surfaces to be clamped and joined together. Two sets of 3 identical prints are clamped along the wetted central pectin spine to adhere all surfaces together. The edges of each of these surfaces are exposed to a humidifier and creased along the toolpaths.
The visual changes of the aggregate surfaces are tracked for a period of time.
- Exposure to air is recorded during the first month and at 12 months.
- Folded shapes are imaged in plan and angled view.
- Changes in color and shape are visible.
2 folded aggregates of 4 biopolymer surfaces are tested that control for the same materials and print orders but vary the 3-dimensional geometries.
Although the aggregates are shaped symmetrically, they do not deform consistently on either side of a single piece. There is significant color change.
