Gospel in the field of printing: 3D printing technology

[ppzhan] The advancement of technology has brought new developments in the field of printing. "3D printing" is the darling of the printing industry from the concept of conception to the real use in production, because it can realize the intelligent printing, which will greatly reduce the enterprise's Cost of production.

"3D printing" makes the production of single items almost as cheap as mass production, which will certainly have a weakening effect on economies of scale. Its profound impact on the world may be comparable to the emergence of the factory of the year.

It works like this. First, you build a rough 3D model on your computer and make the necessary corrections to its shape and color. Then you just need to press the “Print” button, and the nearby machine will start working quietly, making a slight whirring and printing your model a little bit. Whether filling the nozzle with a material or using a glue or laser to hold a thin layer of plastic/metal powder is done by the machine itself.

Since the finished product is gradually materialized, that is, only one layer at a time, this technology has a separate name called "additional manufacturing technology." Through this technology, auto parts, lampshades, and even violins can be made with a level of detail that is stunned.

The advantage of this technology is that it does not require a factory to operate, small items can be made by machines like desktop printers, which are easy to place directly in the corners of coffee shops, shops and even homes; and slightly larger items such as bicycles Frames, car panels, aircraft parts, etc., require more machines and space.

So far, the technology has some limitations, such as materials limited to plastics, resins and metals, the precision can only be a few tens of millimeters.

Like computers in the late 1970s, there are only a handful of college or special industry enthusiasts and workers using 3D printing technology. However, just like computers, with the continuous advancement of this technology, the cost is constantly decreasing, and it is rapidly spreading. The current price of a basic 3D printer is even lower than the price of a laser printer in 1985.

This “add-on manufacturing technology” has many advantages over simply pressing the “print” button compared to traditional production methods. Since the production line is not required, it reduces the production cost and greatly reduces the waste of materials, and the materials are even only one tenth of the original. At the same time, it can also produce special shaped items, but traditional methods are difficult to achieve, such as aircraft wings. Heat exchangers and so on. In short, this technology makes the manufacture of individual items cheaper and faster, and designers can quickly modify them and immediately “print” new samples.

For many years, 3D printers have been used in the manufacture of samples, particularly in the aerospace, medical and automotive industries. Once the design is complete, the production line will be built and will be responsible for the subsequent production and assembly of the parts. However, 3D printing technology has been continuously improved and has been used in the post production process. In the project of manufacturing thousands of products, it is enough to compete with injection molding technology, and as technology continues to mature, it will certainly be suitable for larger-scale production. And because each product is created independently, rather than being produced from a single mold, each product can even be slightly different without incurring additional production costs.

In short, the mass production of 3D printing technology will make scale customization possible, whether it is children's products, shoes, eyes, and even kitchen utensils.

By reducing the barriers to mass production, 3D printing can drive innovation. If you've designed a model on your computer, you can print a dozen to see if you have market needs, then print 50, distribute it to some users, and collect their feedback to modify your design.

This is undoubtedly a huge benefit for inventors and start-ups, and the risks and costs of developing new products will be greatly reduced. Moreover, just as open source programmers share software code when they collaborate, engineers have begun to collaborate on the open source design of 3D modeling and hardware appliances.

Reducing labor demand A profound technological change will make a huge change in the factors of production. Some people think that it will completely disperse the business and thus change the urbanization pattern brought about by industrialization. According to this logic, when each village has a manufacturing machine that can produce various parts at any time, the big factory will no longer be needed. Perhaps this is true to some extent, but the economic and social benefits of the city go far beyond attracting labor to the production line.

Others insist that by reducing the demand for labor in factories, 3D printing will weaken the competitive advantage of low labor costs and low-wage countries, thus causing a large number of manufacturing industries to “move back” to developed countries. This is indeed possible, but like other manufacturers, Asia is ready for this new technology. Moreover, even if 3D printing technology really “turns back” manufacturing to developed countries, it is unlikely to create too many jobs because it is less labor intensive than standard manufacturing.

The technology will not only affect capital and employment, but will also trigger intellectual property (IP) rules. When any product can be condensed in a digital file, they will become easier to copy and distribute, and naturally more susceptible to piracy, except for the music industry. Imagine that when a toy, or a pair of shoes, is transmitted to the Internet, the author's chances of losing intellectual property are higher.

In the future, there will be some regulations for 3D printing, and related intellectual property laws and litigation will continue to improve. With the advent of open source software, new non-business models will also surface. It is unclear whether 3D printing will make existing rules more rigorous (possibly constraining innovation) or more relaxed (possibly encouraging piracy). There is no doubt that the lawyers are gearing up and ready to move.

One thing, at least, seems clear: although 3D printing will create winners and losers, in the short term, this will expand the realm of industry and imagination in the long run.

The impact of great inventions was unpredictable at the time, the steam engine of 1750, the printing of 1450, and the transistors of 1950. Today, we still can't predict how 3D printing will change the world in a long time. But this technology has arrived and will change every area it touches. Companies, regulators and entrepreneurs are the time to think about it.

At least one thing is certain now: although 3D printing technology may cause "some people are happy and stunned" in the short term, in the long run, it will open up new areas of the industrial kingdom and greatly enrich the imagination of industrial production. force.
