In the not-too distant future, common household mishaps a broken cup coffee mug or a lost screw- wont require. A trip to the hardware store. Instead you will just click template on your home 3D printer and manufacture and replacement yourself. The technology behind the 3D printing is moving fort, and it may be among the next disruptive forces in feilds from medicine to defence to manufacturing to home renovation.
The technology that makes 3D printing possible has roots in experimant that led to the developement of photography 200 years ago. Scientists realised that certain materials would undergo chemical changes when exposed to light. One common method of 3D printing called sterolithography, was first developed in the 1980. It creates objects by exposing light-sensitive polymers, called photopolymers, to UV rays from a laser. Photopolymers starts as a combination of several subtances, A large molecule that may be an acrylic or a form of plastic, a small molecule to keep the mixture in an initial liquid state, and a photoinitiator that , when exposed to light of the roght wavelenght, causes the other two substances to bind into solid form.
3D printing is the process of creating 3D objects from a digital file. It starts with a visual design of the object to be printed-computer software can scan existing items or allow us to createa unique design.
This technology could also open a whole new world to counterfeiters not to mention the disturbing idea of printing homemade plastic gens that could evade metal detecters.Could it also spell the end of craftmanship? Perhaps it is just craftmanship of a new sort.
FAST FACT- 3D printed prosthetic can be customised to fit the wearer’s body, and may eventually be cheaper and more durable than tradition prosthetics. Combined with advances in robotics, These limbs could even move with impulses from the wearer’s nerves.
Medical Application:
Researchers working in the medical feild rely on one of 3D paras printing’s greatest strenght. Customisation of complex low-quality items. Low cost in manufacturing today typically stems from mass production, customisation is expensive. But 3D printers can be used to custom-fit hearing aids, casts and other medical devices. While the technology has two way to go, reasercheres hope eventually to use printed organs for transplants and to screen the safety amd effectiveness of grugs before they are tested in humans.
