3D printing – also known as rapid prototyping – has been advertised on the internet a lot. Some believe it to be true. Many others believe that this is a somewhat exaggerated, bogus promotional product that exists around this exciting technology field. So what is 3D printing and who will use it? and how to apply it?
Who created 3D printing?
3D printing was first proposed by Dr. Kodama in 1980. Charles Hull became the first person to successfully apply for a 3D PRINT license and founded the reputable 3D printing company Systems Corporation.
3D printing is more than 3 decades old, but only officially exploded in 2009, after the FDM 3D printing license expired! By now, almost everyone knows about 3D printing technology and its great uses.
What is 3D printing?
You know normal paper printing, right? It is 2D printing. That is the image is displayed on a page of the paper, temporarily called a layer (layer). Meanwhile, 3D printing is a method of separating the 3D model into layers (layers) stacked. Made through specialized 3D printers, the other “paper layers” are made of plastic, resin, or metal, depending on each type of 3D printing technology.
The thinner the printing layer (high resolution), the smoother the 3D printing pattern
Thus, for 3D printing, it is necessary to prepare the following:
- 3D design file
- 3D printer
- 3D printing ink
3D Printing Technology
In the world there are many 3D printing technologies, from simple to complex, from plastic materials to metals, ceramics, glass … We temporarily classify 3D printing technology into 3 main groups:
FDM is the simplest and cheapest 3D printing technology. Also, the printing technology found in most 3D printers on the market. Essentially, an FDM printer will melt and extrude the plastic filament layer by layer to form a pattern.
Principle of 3D printing FDM
- Pros: Technology FDM in3D cheap, easy to use. Print giant patterns!
- Cons: The smoothness is not high, it is difficult to print complex patterns
- Application: FDM has a very wide range of applicability, with virtually every field fine!
Is the common name of a series of 3D printing technologies based on liquid resin 3D inks. Includes, continuous SLA, DLP, and 3D PRINT technology.
Principle of 3D printing RESIN
- Pros: Technology in3D RESIN for products with the highest fineness.
- Cons: in a resin complex process, should be used to print patterns and delicate baby.
- Applications: 3D modeling jewelry, dental, minature model
SLS is a printing technique that uses lasers to project layers of powder (metal or polymer) to make them melt and stick together to create shapes of objects.
Principle of 3D printing SLS
- Pros: Technology no obstacle in3D SLS may have complex shapes. And is the most efficient full-color 3D printing technology.
- Cons: The SLS printing process is expensive and requires a lot of investment in supporting equipment.
- Applications: Modeling of machine details, benches, architecture, 3D printing of human figures
3D Printing Technology Application
Design clothing, accessories, jewelry
Did you know, during a fashion show of Victoria’s Secret 2013, a lot of sparkling jewelry accessories are used by models? More specifically, they are created from 3D printing technology.
According to fashion designer Iris van Herpen, in the near future, we will be able to use 3D scanners and use 3D printing technology to create clothes that fit individual sizes in a short time. This will be the most impressive breakthrough that changes the fashion industry and fashion accessories.
Medical application, human body feces production

Scientists have applied 3D printing technology and 3D scanner to create prostheses, such as legs, arms, teeth, bones on the human body with perfect precision, and flexible movement. at will thanks to other supporting devices. The most impressive point is that the cost to produce them through 3D printing technology is quite cheap, only a few hundred dollars compared to a few thousand dollars as before.
Better yet, some scientists are seriously working on experimental production of complex feces (organs) through 3D printing and cell separation technology. That is, these organs can “live” and take on the tasks equivalent to the original parts of the human body.

The biggest application of 3D printing technology is probably component manufacturing, any details from simple to complex can be used by 3D printers to create. This will increase productivity and reduce costs compared to the traditional way of production today.
In addition, 3D printing technology also helps users to repair and replace damaged components easily. Whether that savings is rare or is no longer in production. Of course, you need to have the design data file of the components to be fabricated, currently, on the Thingiverse website, there are designs for more than 2,500 spare parts of all objects.
Confectionery is created using 3D printing technology
It sounds unbelievable, but with the breakthroughs of technology, it is possible to produce everyday foods through 3D printers. At the Las Vegas consumer electronics show, 3D Systems showed off a 3D printer that can use chocolate, sugar, and vanilla to create a variety of cakes and candies of different shapes, of course. can eat it.
More interestingly, a company called Natural Machines has taken advantage of 3D printing to produce pasta and many other consumer foods. Of course, you will find it very difficult to distinguish them from appliances manufactured by traditional technology.
A construction company said it used a “giant” 3D printer to build 10 houses in just 24 hours. This is difficult to do according to the traditional method today.
More specifically, they use a 3D printer to spray cement and another substitute for concrete to create a fairly cheap, complete house, just $ 5,000. However, at first, the size of the house is still small and it takes more time to complete.
It can be said that 3D printing technology has no limits, you can print any object, detail, or object that you can think of. Perhaps the only limit is human imagination only.
This proves that 3D printing will be the future of the world when everything for human life will be associated with 3 words “3D printing technology”.
