4D printing Programmable Textiles

Posted on Updated on

 

According to the comments from the videos, ” 4D printing Programmable Textiles looks like, Lays potato chips are made. Once they’re produced on 3D printers, objects made of programmable materials continue to take shape, folding, unfolding or assembling themselves in response to outside stimuli such as light, movement, heat, pressure or water.

The programmable Materials consist of material compositions that are designed to become highly dynamic in form and function, yet they are as cost-effective as traditional materials, easily fabricated and capable of flat-pack shipping and self-assembly. These new materials include self-transforming carbon fiber, printed wood grain, custom textile composites and other rubbers/plastics, which offer unprecedented capabilities including programmable actuation, sensing and self-transformation, from a simple material”. 🙂

The bone repairing with 3D Print

Posted on

The bone repairing is very important. Due to the age and other factors, bones suffer from bone defects and disorders.
According to the Journal of Materials Chemistry,”The aim of this study is to set out to solve these problems by applying a modified 3D-printing method to prepare highly uniform CS scaffolds with controllable pore structure and improved mechanical strength. The in vivo osteogenesis of the prepared 3D-printed CS scaffolds was further investigated by implanting them in the femur defects of rats. The results show that the CS scaffolds prepared by the modified 3D-printing method have uniform scaffold morphology. The pore size and pore structure of CS scaffolds can be efficiently adjusted. The comprehensive strength of 3D-printed CS scaffolds is around 120 times that of conventional”.

Cleft lip surgery using 3D Printing

Posted on Updated on

My Father In-law was the famous surgeon for doing cleft lip surgery. According to the Scientific Reports volume,”Computer-aided design and computer-aided manufacturing (CAD/CAM) technology have been implemented in the treatment of cleft lip and palates (CLP) by several research groups. This pilot study presents a technique that combines intraoral moulding with a semi-automated plate generation and 3D-printing”.

Custom building envelopes straight from the 3D printer

Posted on Updated on

According to Moritz Mungenast, he is Associate Professor of Architectural Design and Building Envelope, “Custom building envelopes straight from the printer and not only is the facade element very stable, it’s also translucent and multi-functional. For example, cells inside the element provide stability while at the same time creating air-filled cavities for optimum insulation. Waves in the material create shadows. Thin embedded tubes let air circulate from one side of the element to the other, ensuring the best possible ventilation. And the micro-structured surface provides for perfect acoustics. All these functions are scalable and can be adapted to accommodate individual requirements at no extra cost”.
