4D Knit Textile: The Experimental Studies of utilising knit textile as the trigger of 3D Printing’s Self-Morphing

"Since the knit has been chosen as the textile substrate, it can trigger the deformation behaviour of the composite after 3D printing."


Referencing from the definition of 4D printing, which the 3D printing shifts to another level by a time changing element, the hybrid composite with the responsible knit substrate to external stimuli can be defined as 4D textile. According to the use of smart materials as filament for the 4D printing, the figure presents the difference between 3D printing Knit and 4D Knit Textile by using the high performative yarn to make the smart knit textile. 4D Knit Textile has not only extended the boundaries of application for both of the technologies but also provided a new pathway for the exploration of 4D printing with more reachable material. This study has explored the diversity of 4D knit textile and its possible applications by sampling with different types of functional yarn and engineered stitch structure in order to enrich the future research direction of 4D printing.


AddiToy Mask

the finalist of the International Design Award Covid-19 Design Innovation Grant

By collecting the data from 3D face scanning,  the designer can calculate the measurements and make the mask pattern digitally. After translating the pattern with digital software, the knit base for the mask can be done fully-fashioned by the machine with 100% wormwood anti-bacterial yarns. Finally, the designer just brought the knit base to the 3D printer for printing the nose clip and supporting pad. The outcome is made 100% material zero-wasted with perfect fitness and comfort. At the same time, it can be washed and reused up to 50 times.



International Design Award 2018 the Golden Prize of Textile and Materials

Technical Principle  AddiToy is developing a technique of combing 3D printing and knit to create new textile for fashion design.   This innovation introduces a new aesthetics and zero-waste fabrication to the fashion industry by creating customizable products with unprecedented shapes, structures, materials, and texture.

Experimental Process  This technique is a method of direct 3D printing onto knitting, including choosing the suitable yarns and engineering the knitting process, designing the 3D pattern for printing, and choosing the suitable filaments, placing the knit into a right position and printing onto it. For more special outcome, the printed textile can be machine-felted with the certain temperature at a certain time duration.

Application  This new technique has been applied in to my MA final collection with several pieces of products, including a book of samples, garments, accessories, and several pieces of perfume prototypes. All of them have shown the possibility of this technique and how it could be applied to different products functionally.  In the future, AddiToy can provide technical service to design studios for using this technique and products into their collections, Further, AddiToy will be actively participating into the process of upgrading the traditional and resource-consumed fashion industry by developing 3D printers suitable for fashion industry.
