4D printing materials are known as 'smart materials' or 'shape-memory polymers'.

So, how does 4D printing work? To understand this, we need to look at the materials used in the process. Gradually 4D printing technology is used in many industries such as robotics, aerospace, construction, etcĪfter all, still, a lot of research is going on 4D printing and materials used for 4D printing and a lot of applications can be found in future.If the pipes are made up of 4D printing then the water flows through the pipes can adapt their thickness depending upon provided conditions, then if we can control those conditions that mean we can control the pressure and velocity of the water.If the car seats are made up of 4D printed material, depending upon the pressure inside the car it can change its thickness and change the comfort level automatically.4D printing is also used for smart packaging.4D printing is used to minimize the size of objects such as safety bags, which under accident conditions expand due to high disturbance.Most of us have heard about touch me not plant, THEY RESPONSE TO TOUCHĤD printing is not only limited to health care industry but these materials can be used in various industries for example 4D printing is a technology where we build 3-dimensional objects by adding smart material layer by layer which can further change its shape and size with respect to time depending upon various factors such as temperature, pressure, electrochemical solution, humidity, light, electric field, magnetic field, etcīut when it comes to 4D printing, we use materials such as ' shape memory alloy s'which have the ability to change their Shape and size depending upon the provided condition or factors with respect to time, That means they change their shape and size after 3D printing under the required factors, Here is where 4th dimension can be observedįor a real-life example, when we put dry beans in water their volume and weight increase gradually with respect to time
