The advent of 3D printers shows that information technology comes out of several stages 5

The incorrect description of 3D printing technology is that 3D printing is a rapid prototyping technology, and the printing speed is very fast, and it often takes only a few minutes to mold.

3D printing technology appeared in the mid-90s of the 20th century, and it is actually the latest rapid prototyping device that uses technologies such as light curing and paper lamination.

The printer contains "printing materials" such as liquids or powders, and after being connected to the computer, the "printing materials" are stacked layer by layer through computer control, and finally the blueprint on the computer becomes a physical object.

In layman's terms, a 3D printer is a device that can "print" real 3D objects, such as printing a robot, printing a toy car, printing various models, and even food.

The reason why it is colloquially called "printer" is to refer to the technical principle of ordinary printers, because the process of layered processing is very similar to inkjet printing.

Now the technical ability is constantly updated, technology and equipment have been greatly improved, because only continuous progress will not be eliminated by the society, now there are more and more 3D printing processing industries, now it is not only 3D printing processing and 3D printing processing services, because it can bring greater benefits to enterprises, so it will be so popular, so, let us know what are the advantages of 3D printing?

1。There is no additional cost to make cluttered items. In the case of traditional production, the more chaotic the shape of the object, the higher the production cost.

For 3D printers, it does not increase the cost of manufacturing objects with messy shapes. Making a gorgeous object out of cluttered shapes doesn't take more time, technology, or cost than printing a simple box. Creating a chaotic project without increasing costs will break the traditional form of pricing and change the way we calculate production costs.

2。Product diversification does not increase costs. 3D printers can print many shapes, and each time they can make different shapes like a craftsman.

Traditional manufacturing equipment has fewer functions and is limited in shape and variety. 3D printing saves the cost of training mechanics or buying new equipment, and the 3D printer only requires a different digital blueprint and a new batch of raw materials.

First of all, 3D printing realizes the three-dimensional printing, which can be said that the model we create in the software is perfectly printed, including the selection of materials. In addition, it is more creative, and now there are even 3D printed cakes and so on.

Regarding 3D printing technology, the following statement is incorrect ().

a.It can directly output the 3D graphics held in the computer as 3D plastic parts.

b.It enables controlled fabrication from microstructure to tenancy macrostructure.

c.It also has the disadvantages of low manufacturing efficiency and high cost.

d.Its market size accounts for more than 50% of the global manufacturing market.

Correct answer: d

Hello, I am glad to serve you and give you the following answers: powder sintering technology is the key technology that makes 3D printing bright fiber technology widely used. Powder sintering is a technology that makes three-dimensional objects by means of thermoforming, which can sinter powdered materials into tightly structured objects.

The basic steps of powder sintering technology are: first, the powder material is put into the sintering machine, and then the imitation powder material in the sintering machine is heated to make it into a molten state; Next, the molten powder material is evenly stacked on the mold to form a layer; Finally, the molten powder material in the mold is cooled and allowed to solidify to form a complete three-dimensional object. The advantages of powder sintering technology are:

It can manufacture fine three-dimensional objects, and it can also manufacture complex structures, which makes 3D printing technology can be applied to more fields. Personal tip: Powder sintering technology is a very effective 3D printing technology, which can create fine three-dimensional objects and complex structures, so that 3D printing technology can be applied to more fields.

Therefore, when using powder sintering technology, attention should be paid to controlling the sintering temperature to ensure the uniformity of the molten powder material, as well as the cooling rate of the molten powder material to ensure the curing effect of the molten powder material.
