First Post (Parametric Weaving)

This blog has been created to record my experiments in digital fabrication and share them with the maker community. My primary interest is to explore the possibilities of digital modeling techniques by producing physical studies through the use of various fabrication mediums like 3D printing, Mold Casting, CNC routing, Laser cutting, etc. My goal is to make this blog an open conversation about Digital tools and techniques, and how they each relate to design.

To kick it off I want to share some observations from a recent 3d printing test in Parametric Weaving.

Following a parametric modeling tutorial designed to recreate the form of the Beijing National Stadium I wanted to test the 3d printers ability to handle different weaving densities at a small scale. Link:

The Grasshopper model has a slider built in to adjust the amount of section cuts that are taken from the template shape to determine each spanning element.

The first test was with the medium density form (30). Although there was a lot of stringy filament in-between members the overall form shows through.

Print Settings:

- .05 mm

- 100% infill

- Rectilinear infill

On the second print I tried to do two at a time with less successful results. Members snapped on the small density form (10) several times during the print. Additionally the stringy filament bridged between pieces and eventually caused the High density piece (50) to pull from the bed.

Med Density (30) High Density (50)

Next time I might try doubleing the size of the prints and thickening the members.
