The MIT 3D-Printed Shape-Memory Structures and its relationship with 3D Printer's Auto-off Switcher

Updated: Oct 28, 2021

In essence, the following is what is going on: Engineers from Massachusetts Institute of Technology and Singapore University of Technology and Design (SUTD) are using light to print three-dimensional structures that “remember” their original shapes. Even after being stretched, twisted, and bent at extreme angles, the structures — from small coils and multimaterial flowers, to an inch-tall replica of the Eiffel tower — sprang back to their original forms within seconds of being heated to a certain temperature “sweet spot.” Of course, the whole article, which is written by the MIT News, can be accessed here:

When it comes to the applications of these shape-memory-polymer-made objects, the authors of this article have already pointed out that they can be made into biomedical devices, soft robotics, wearable sensors, deployable aerospace structures, shape-changing photovoltaic solar cells, and artificial muscles. When I invented my product - the 3-D Printer’s Auto-off Switcher – which can be viewed through here – – I made use of a temperature sensor which acts as a switch that switches on when its temperature is higher than 50℃ and switches off when its temperature is below 50℃. The inside of these temperature sensors can also make use of these shape-memory-polymer-made objects. That being said, the temperature sensors that I am using right now work just fine, and I’m not suggesting that I’ll demand my suppliers to modify them. I’m just suggesting that this is one possibility to make the internal contact points of the temperature sensors that I am using. I also think that these shape-memory-polymer-made objects can be made into electric breakers that are rated at lower than 1 kilo-Volts. That is, instead of responding to heat, those types of shape-memory-polymers that respond to the stimuli of electric current will be used.

So, thanks very much to you, Professor Nicholas Fang, Professor Kevin, Qi Ge, Professor Howon Lee, Ms. Jennifer Chu, and others from SUTD and Georgia Institute of Technology, for doing all of your works.

One more thing: I know how severe the misinformation on the internet is. This is why I do not want to be one of those who spread misinformation. It is also why I really recommend you to contact me and have me starting video meetings with you, or even meeting you in person. This way, you will: a). Get to know whether it is a real person blogging here, and b). Apply your own method to verify how trustworthy I am.
