How did the 3D printer come about?

Let's not bore you too much with dates and briefly retell the history of 3D printing.

The harbinger of 3D printing. In the early 1980s, Dr. Hideo Kodama developed a rapid prototyping system using photopolymer, an acrylic-based liquid substance. The printing technology was similar to the modern one: the printer printed the object according to the model, layer by layer.

First 3D printing

The production of physical objects using digital data was demonstrated by Charles Hull. In 1984, when computers were not much different from calculators, and ten years before the release of Windows-95, he invented stereolithography, the forerunner of 3D printing. The technology worked like this: under the influence of an ultraviolet laser, the material solidified and turned into a plastic product. The form was printed on digital objects, and this became a boom among developers - now it was possible to create prototypes at a lower cost.

The first manufacturer of 3D printers. Two years later, Charles Hull patented the technology and opened the 3D Systems printer company. It released the first machine for industrial 3D printing and is still leading the market. True, then the printer was called differently - an apparatus for stereolithography.

The popularity of 3D printing and new technologies

In the late 80s, 3D Systems launched mass production of stereolithographic printers. But by that time, other printing technologies had also appeared: laser sintering and deposition modeling. In the first case, the powder was processed by the laser, not the liquid. And the majority of modern 3D printers work according to the fusing method. The term "3D printing" came into use, the first home printers appeared.

Revolution in 3D printing

At the beginning of the 2000s, the market split into two directions: expensive complex systems and those that are available to everyone for printing at home. The technology began to be used in specific areas: for the first time, a bladder was printed on a 3D printer, which was successfully implanted.

How a 3D printer works

Basically, Best resin 3d printer under 500 consist of the same parts and are similar in design to conventional printers. The main difference is obvious: a 3D printer prints in three planes, and in addition to width and height, depth appears.

Here are the parts that a 3D printer consists of, not counting the body:

  • an extruder, or print head, heats the surface, measures the exact amount of material using a gripping system and squeezes out semi-liquid plastic, which is fed in the form of threads;
  • desktop (it is also called a working platform or printing surface) - on it the printer forms parts and grows products;
  • linear and stepper motors - set the parts in motion, are responsible for the accuracy and speed of printing;
  • clamps - sensors that determine the print coordinates and limit moving parts. They are needed so that the printer does not go beyond the desktop, and make printing more accurate;
  • frame - connects all the elements of the printer.
