Life Saving Engineering Ideas That Changed The World

For hundreds of years engineers have been working on medical projects that are designed to make our lives easier and healthier. These life saving ideas came to be after much research, and they continue to change our lives in so many ways.

3D Printing

Just like the online Roulette Australia has to offer, 3D printing is a game changer in so many ways, and has been making huge strides in the medical field. It is being used to print organs; prosthetics and parts for pacemakers, and engineers are constantly working on other ways to adapt it to their purposes in the medical field.

The use of 3D printing in the medical sector could lead to saving of lives in so many cases, and could even help deaf people hear again, or help blind people see.

Tinned Food

This is quite a jump from the high tech world of 3D printing, but canned food is one of the greatest engineering feats ever. The canning process was invented in 1810 by Frenchman Philippe de Girard, and his invention led to the first canning factory opening in London a few short years later.

Since then, tinned food has become a staple, and has been responsible for keeping soldiers alive when at war, and sustaining the navy while at sea. It allows for food to be preserved for extended periods of time and keeps it fresh.

The Microscope

The microscope’s history goes all the way back to 1665 when Robert Hooke’s images of Micrographia were used in a book. The microscope has been used for everything from detecting disease to cultivating antibodies to help cure it, and it continues to be one of the most valuable objects in scientific engineering.

Without the ability magnify cells and bacteria so many times, the human race could even have been wiped out by an innocuous virus by now.


Today, having an X ray is a quick and painless process and there are even 3D machines such as the Panorex that takes a 3D X ray of your upper and lower jaw while you stand still. The first X ray was discovered in 1895 when Wilhelm Conrad Roentgen accidentally realised that different exposures caused different reactions.

He was able to apply these principles to film, and thus the first X rays were made. X Rays soon became an integral part of the medical world, as previously, doctors had simply had to guess whether or not a bone was broken, where and how badly.


An ECG or EKG can save your life as it picks up the electrical activity of your heart and can detect any abnormalities. The electrocardiogram was invented in 1895 by Willem Einthoven and he was awarded the Nobel Prize for his discovery.

ECG’s have become increasingly more sophisticated and hi-tech over the years and have been integrated into other medical equipment, but they retain at their core the same functionality and principles engineered by Einthoven over 100 years ago.
