Non Planar Strategies
- Printing extreme variegated conditions
Print Strategy: Initial attempts were more frequently in pursuit of whole models, were over reinforced and were constructed on pre morph schwartz surfaces prior to the print path iteslf undergoing a morph. Though this resulted in the earliest successes with freestanding intact modules, its efficacy was inverted on the type 4 tests which experienced extreme compression in some areas.
As a result of this testing and research, key printing techniques were adopted to function “in situ” beginning slicing procedures withing the morphed module, despite the high level of unpredictability that accompanies that approach.
Idealized Outcome: Box morphed Schwartz surfaces from an early iteration of the base mesh, given a steeper sloap and more reciprocally leveled top with the intent of fabricating a model to the scale of a small stool (about 20” tall)Design Premise: Vaulted mesh inflated using Kangaroo simulation in Grasshopper. Mesh is offset with its lowest order sorted and confined to 0 on the Z-axis.Design Parameters: Mesh detail is halved. Larger twisted boxes are more relevant to the project scale. Will also aid in developing outer parameter limitations, r.e. degree of twist/ level of non-planarity.*Digital Model of print geometry/knot variation across components based on evaluated slope at individuated normals.Physics-based quad mesh is thickened to form matrix. Dimensional cells receive twisted box variations of minimal surface based modules. Slicing was attempted in both sequences i.e. before and after module translation. Schwartz surfaces were selected for their unique difficulty and capacity to resist polar compression when threaded with tensile connections (chord through shared walls and printed cores.)Instatiation Process And Slicing Procedure: The quartered, boxed volume showing the four unique volumes and their mirror. In the bottom is the build platform. at 0,0,0 all parts, having been morphed, are reoriented to slice the geometry relative to how it will be printed. The boxes are sequenced in ascending order, 1-4. Each successive box is more distended, more warped, and has a greater deformation in refards to its overall planarity.Polar Slicing: About the “axis” of the twisted boxDispatched Support Structure + Aperture: Mesh detail is halved. Larger twisted boxes are more relevant to the project scale. Will also aid in developing outer parameter limitations, r.e. degree of twist/ level of non-planarity.Exterior “Weave” Patterning: Mesh detail is halved. Larger twisted boxes are more relevant to the project scale. Will also aid in developing outer parameter limitations, r.e. degree of twist/ level of non-planarity.ToolpathsPrint Taxonomy“G”“H“Module Type B-1
Note how the texture of the knot pattern shifts vertically and how the respective patterns used maintain a persistent correllation to surface normal despite their discrepancies in pattern and magnitude
