The course for introduction to the digital fabrication was floated in order to understand the relation between the machines and the computer data, how the algorithms used to create the forms in computer can be generated using specific fabrication techniques. The main focus of the course was oriented on the recursive geometry, starting with the base geometry which can be aggregated in all directions. Main techniques we are working on are Laser cutting, 3d printing & CNC Milling.

Laser cutting – Tri-nodular formulations

The criteria of design  was to develop a recursive geometric form using laser cutting machine that can be manipulated with complex fabrication perspective. The concept that we had evolved is tri-nodal form with a base geometry that can recurse itself into a much complex polyhedral form based on the  joining parameters. The material incorporated was 3mm transparent Acrylic board with interlockable joinery with specific tolerance setup as per the iterated tolerance markup of the interlockable parts.

The Module had been incorporated engraving on tween lines that would be the face of the overall recursive module.


Aggregation Process:



3D Printing – Modular Growth

The concept was to create a polymorphic non identical nodal form with multidimensional aggregate form in three of the faces.
The nodes that share the same face within the shape are mirrored to create new attachments to continue the recursive

We observed a constrain in printing a specific node as the support anticipated was not sufficient but later on we rectified it on the other node prints


The overall form has 12 different nodes developed as per the overall geometry.

Aggregation Process











The CNC milling project concept was evolved from the natural recursive geometric sphere formulations in terms of crest and trough differentials of  moulds on surface. The aim of the milling project was to achieve a flat extruded geometry with spheres. The shape can be replicated and iterated in three axis  to form the final recursive output.
