Figure I: Comparison of the deformation and color change of radially aggregated and nested biopolymer prints aged over 1 year with different 2-dimensional geometries and 3-dimensional forms.
Figure II: Toolpaths from printed biopolymer sheets in set.
Figure III: A series of bilaterally symmetric prints are composed of a pectin chitosan infill base layer with a cellulose lattice surface layer. The center lines of each print have a region of pectin infill printed above the cellulose lattice.
Figure IV: A set of 10 different 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 folded into adjacent surfaces.
Figure V: Renderings and drawings of folded biopolymer schematic design.
Figure VI: Composite pie chart circle diagram comparing ingredient volum and cost of materials for each single material print (8 swatch types).
Figure VII: Diagram comparing volume of material, print duration, and cost for differen biopolymer formulas used in each print in the series.

These experiments examine how centrally aggregated and nested 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 center lines of each print have a region of pectin infill printed above the cellulose lattice. A set of 10 different 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 folded into adjacent surfaces.
- Exposure to air is recorded during the first month and at 18 months.
- Folded shapes are imaged with and without backlighting in plan view.
- Changes in color are visible.
1 nested aggregate of 16 biopolymer surfaces are tested that control for the same materials and print orders but vary the 3-dimensional geometries: https://designedecologies.com/U-Fold
Although the symmetrical aggregate does not experience major deformation, portions have cracked due to internal pressures. There is significant color change
