The parametric process allows a very tight design where the zipper is no longer added as an after thought or adapted to fit, but is created to perfectly fit the surface

The process of creating a parametric model started with understanding what are the controllable parameters in the teeth, in the pattern and the zippers head.

Prototyping process: considering the limitation of the printer along with different printable materials and structural limitations

Controlling the shape of the teeth and the size ratio between the rows

Control over the surface tangency, the rows follow the surface and fit the teeth size and shape to "solve" the new form

The zipper can follow different curves

The zipper system had many parameters each can be manipulated and modified

Rethinking the conventional zipper

Zipper | RichRach

The zipper has been in our lives for over a hundred years, but when was the last time we stopped and examine it?


In RichRach project, I am taking a closer look at the zipper's qualities, exploring its mechanism and how it can be manipulated and controlled.

The conventional zipper is linear, flat and symmetrical, but none of these qualities is a must : zippers can still function as a-symmetric, a-linear , angular or even spiral. Moreover, due to the way it's production line is build, it is hard to make modifications and manufacture limited editions or individual pieces.  

First step was understanding the zipper: how does it work? how it is manufactured? what is the formula that defines it? Can it be described mathematically?

Using this knowledge, I created a catalog of fully functional zippers of angular zippers : 0° to 180° degrees , circular zippers : in different radius and curvature, asymmetrical in teeth size, length, width and  all combinations.

Parameterizing the zippers allows it to fit specifically to a design and function and to be customized: controlling parameters such as size, ratio, offsets angle and curvature. The zipper can even fit itself to a surface, Allowing complex structures that can be integrated into the design process in a more organic manner.

Changing the hierarchy between the zipper and its "habitat" transforms the zipper from a secondary addition that is too often overlooked into the center of attention by challenging its shape and mechanical structure.

In addition, using additive manufactioring enables small scale collection of zippers that are customized or personalized in each case according to the needs of the designer.
