Science surprises us every decade with many inventions and discoveries that make our lives easier and more enjoyable, as the invention of airplanes that made our travel faster, more comfortable and easier, and the invention of the hard disk that made us store millions of information and files on a portable hard disk for us to use anywhere.
But have you ever dreamed of making a house or a piece of art in a short time, not more than a day or a week at most, imagine if we used it in our life a lot, how it will change our life or change the way we think about doing things, I think it would be nice Using them we can save a lot of money and a lot of time to do these things.
I think this became a reality after 1981 after Hideo Kodama invented a method for creating solid objects using ultraviolet lights, which was the beginning of lithography .
This is a method that depends on the use of limestone in printing and not mixing oil with water, and this method was found in the 18th century for printing two-dimensional shapes, but after 1981, it began to print several two-dimensional layers and mount them on top of each other to create three-dimensional models.
This technology has affected the future of many medical, military, artistic, academic, architectural and construction fields ... etc., it has had a positive impact in these areas and made it easier to work with, but it also possessed negative aspects in all fields as well and in the fields
The work of three-dimensional printing is heavily involved in the engineering field to design miniature models of engineering tools and objects that the student who studies engineering needs or needs after graduation at work.
- Use them in the construction process
Many buildings have been built completely using this technology, which made it easy to build and very quickly, and it is mentioned that this process was used in building many buildings quickly in developed countries and other countries such as Saudi Arabia, Dubai and others.
This technology has opened a wide field for the architect's thinking, as it has become easy to build the buildings that the architect dreams, and the architectural student may use this technique to build the models that he models on the architectural programs quickly, so that it becomes easy to understand for the teacher or professor.
But the negative side of 3D printing in this field is the loss of many builders and their jobs and occupied their place, and this also affects the unemployment rates in the world and this is negative in all areas, and also one of the drawbacks of this technology is the reduction of creativity among engineering students and engineers, which makes them depend on this machine Majorly to get high grades and this thing does not produce competencies from students to get work.
It became easy to manufacture weapons, just model them on the computer and give a print order, which the machine will print according to the material that you use for weapons and you will save a lot on the armies of countries in general.
This technology also has a negative in this field, so if we think that if this technology reaches the evil people of the world, they will manufacture many weapons and quickly because they do their criminal acts, and this also affects the security of societies in the world.
It will be easy to manufacture the sculptures that need a lot of time to do them, or even for fine arts students who want to show their work in a more beautiful and clear way, but also if we come to it on the other hand, it will spoil the general taste because of the manufacture of many art forms quickly, which makes them worthless. Her when people.
The medical field
It is one of the greatest areas in which 3D printing can work because it will change the life of a person for the better. It may be used in the construction of artificial limbs and may also be used to reduce deformities in some patients.
Just imagine if this technology spread in the world how it will change our life, but everything has positives and negatives so we have to be careful in using it or only the people who deserve it are the ones who should use it.
It may also be used in building artificial teeth for the elderly and those who have lost their teeth.
