Ruled Surfaces with Silkworm

OLYMPUS DIGITAL CAMERA

Some tests done with Silkworm based on parametric line geometries generated with a simple  grasshopper definition. The principle is to create a solid structural outer shell which supports inner lines that span between different points of the perimeter. The inner lines define a ruled surface while the outer shell is a prism with an n-sided polygonal base.

 Use the definition above to generate uniform ruled surfaces:

 For more customization options and to get non-symmetrical shapes, the definition above can be used:

First Silkworm Release!

Announcing the first release of the Silkworm plugin for Grasshopper!   This release includes components to convert Grasshopper geometry to paths, edit the GCode properties of paths, create and preview a print model and convert this to GCode for 3d printing.   As an introduction to the Silkworm workflow we have included this short video tutorial for the 3d spiral tutorial:

 

 

Manual and Plugin can be downloaded from here:

Example Files can be viewed and downloaded here:

To follow also will be a component to send the GCode directly to the printer (in development).  For now, you can use an external interface such as Pronterface.  Please note, at the moment we have only developed this for Rep Rap firmware, but we are planning to extend to other variants.

In addition we are developing a techniques wiki where people will be able to create, edit and share techniques they have developed using silkworm.   It is hoped that we will be able to curate a large repository of 3d printing techniques through Project Silkworm that will aid designers in continuing to push the boundaries of 3d printing and digital fabrication.

If you are interested in contributing to this project or have any questions, please get in touch.
