Design Through Making

PopUpPrints is an ongoing exploration of the material qualities, geometrical possibilities and range of potential uses of inflatable objects based on the making process.

While traditionally, three dimensional inflatable objects are hand welded in a process similar to manual sewing, this project is based on the innovation of using the up to 300°C hot nozzle of a 3D printer to seal two layers of elastic TPU foil together in specific patterns.

Developing distinct geometries through an iterative design process opened up the possibilities of using this 2D production process to create objects that emerge into 3D shapes when inflated.

To demonstrate the potential and possible precision of this process, a series of hinges and objects with predefined bends and kinks were created. 

Potential applications include the possibility of creating incredibly lightweight 3D structures from flat packed, easy to ship flexible sheets in a matter of seconds, without any tools or equipment by injecting expanding polyurethane foam.

An alternative use is the simplification of moulding and casting methods by using geometries where one of multiple chambers of an object is filled with a curable material in it’s liquid state and the others are then inflated to push and hold the material into the desired three-dimensional shape until it is cured and stable on its own.

The Procrastinator is a machine made of a welded steel frame and a stepper motor and a brass sharpener on a slider, that relentlessly sharpens every pencil you feed it to the point of beautiful destruction. 

Originating form mechanisms of procrastination and the small, unnecessary habits we fall into when trying to distract ourselves from working, the procrastinator explores the ambivalent principle of sharpening pencils. In order to create value in form of a sharp and usable pencil, you have to shave off more and more of the wood, slowly destroying it in the process until it ultimately is not usable anymore. To show and exaggerate both mechanisms, the sharpener, driven by a motor and gravity, pointlessly sharpens the already sharp pencil, turning one after the other into one giant pile of pencil shavings.
