How 3D metal printers are impacting traditional casting processing

3D metal printing has some impact on the traditional foundry industry, but it has little impact. It is still difficult for 3D metal printing to be applied to the jewelry industry. Let's talk about the impact of 3D metal printing on traditional casting.

Casting has low cost, mature technology, and many types of applicable materials, while the cost of 3D metal printing is very high, just a piece of equipment will cost millions, generally suitable for some specific materials, complex structures, short processing cycle of parts printing, generally also need complex post-processing. Therefore, traditional casting will still have a wide application market. As for the application of the jewelry industry, the products of direct 3D metal printing require some post-polishing and other treatments, and some hollow structures are difficult to deal with.

The 3D printers used in the general jewelry industry are mainly used to print plastic models, and some can replace traditional wax models to further manufacture metal parts.

3D printing (3DP) is a type of rapid prototyping technology, which is a technology that uses adhesive materials such as powdered metal or plastic to construct objects based on digital model files. 3D printing is usually achieved by using digital technology material printers. It is often used in mold manufacturing, industrial design and other fields to manufacture prototype model proofing.

Therefore, the application and popularization of 3D printing technology has a certain impact on the traditional prototype processing industry. The 3D printer does not require complex maintenance, and the workbench material filament can be cleaned quickly and easily after printing; The completion of ordinary CNC machining requires special personnel to clean the machine tool, clean up the waste, etc., and the time is long (labor cost). Because the early prototype model production was limited by conditions, most of the work was done by hand, which made the prototype long construction period and difficult to strictly meet the size requirements of the appearance and structural drawings.

Now the popularization and application of 3D printing technology, choosing a good 3D printing prototype model manufacturer can avoid various problems encountered before, whether it is delivery time or quality. Shenzhen Tianshunda 3D printing is such a 3D printing technology company.

At present, the application field of 3D printing is mainly based on composite materials, and metal materials cannot be used for 3D printing molding. However, for the metal processing industry, it still has an impact on sample processing and model processing. However, it is still too early to replace the traditional parts processing industry.

First of all, 3D printing, in the case of batch processing, its efficiency is still a problem, and the cost cannot be compared with the cost of traditional metal parts processing, which is much higher, for example, the current automatic lathe processing efficiency is very high, and in the production of lathes, non-printing molding is comparable.

Secondly, materials, as mentioned earlier, 3D printing is mainly made of some composite materials, which are made of the most common steel, iron, copper, tin, stainless steel, alloy materials, etc., which cannot be completed by 3D printing, and the cost and application fields of composite materials are limited.

In addition, 3D printing, only for the processing of some special-shaped parts, has advantages over traditional machine tool processing, and is limited in the batch and large-scale production of the industry.

It didn't make a difference. 3D exclusive printing can correct many loopholes in traditional processes.

I don't think it will have an impact, and it will probably cover some of the flaws of the traditional approach.

It didn't matter, because he printed every print like this.

If anything, it's probably rough in my work.

It will replace the traditional foundry industry, and some people will be unemployed.

3D printing has accelerated the decay of traditional casting.

It doesn't matter, because each has its own advantages.

There is no effect, each has its own characteristics.

With the rise of 3D printing, the traditional foundry industry is gradually eliminated.

3D metal printers expose many loopholes in traditional casting processing.

More than 30 kinds of titanium alloy, aluminum alloy, stainless steel, die steel can be printed! Part performance and forging performance! (Xi'an Bright Special).

Yes, it can be printed.

The first 3D printer that can print metal products is an industrial-grade 3D printer. Also inside is 3D printing capacity.

It is a kind of machine that is different from desktop 3D printers.

How metal 3D printers work: Based on digital model files, objects are constructed by printing them layer by layer using adhesive materials such as powdered metal.

The metal products that can be printed are: parts [airplanes, cars, bicycles], some collectible models, and handicrafts such as rings.

It is possible to print metals at relatively low temperatures. Springs don't.

3D printing in metal.

During the process, various problems can arise, such as porosity.

Residual stress, density, warpage, cracks, and surface finish.

<> capillaries. One thing we need to know is that there will be some small holes in the process of metal 3D printing. When the size of the powder is larger than the layer thickness, or when the laser lap is too sparse, small holes can appear, or the molten metal cannot fully flow into the corresponding area.

Metal 3D printer operators need to adapt equipment for specific materials and tasks. For specific materials and tasks, equipment parameters (e.g., laser power, spot size, spot shape) need to be adjusted to minimize porosity.

Density. Good metal 3D powder fluidity is necessary to ensure the flatness and density of powder laying, which will affect the porosity and density of the product. The higher the density of the metal 3D printing powder, the lower the porosity of the part, and the higher the density of the part, the density of the part is inversely proportional to the porosity.

The more porous a part is, the lower its density and the more likely it is to fatigue or crack under pressure. Therefore, for critical applications, the density of the part needs to be more than 99%. 3D printing usually makes parts step by step by melting metal powder by laser or electron beam, because the metal powder of 3D printing is very small, generally 15 microns to 100 microns, when the laser and electron beam irradiate the metal powder, the powder melts and vaporizes, and the gas flows, causing the powder near the molding path to be washed away, which may lead to tiny pores and defects near the powder molding.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

The problem is that 3D printing products are not particularly strong, and may be affected by external forces, will be affected by the impulse of Wenna, will be easy to break, and the quality is not particularly good. Refer to Jane.

It may affect human health, because in the process of operation, a lot of metal powder will be produced, which may affect nerves, may affect the respiratory tract, and may suffocate; If it is serious, Duan Kai may cause a fire, because the metal powder is only after Zheng Mo encounters an open flame, it may burn, and it may mean that the burning song will occur**.

These problems are Gao Draftsen, there will be quality problems of Jing Eggplant, very soft, can not be used normally, can not contact water, the quality is not particularly good, can not be used for a long time, will be out of Qi Mu is now stuck.

It is necessary to pay attention to the density, the fluidity of the 3D metal powder, the flatness, the porosity, and the stability of the transport chain when making it.

Yes,3D printing metal molds are mainly used in conformal cooling mold printing.

Metal mold cooling system is one of the design mold projects, when the plastic raw material of the mold is heated and injected into the mold with a lower temperature, it is necessary to wait for the mold to cool down to obtain the finished product, and then it needs to rely on the cooling system to cool and demould. The cooling system affects the demoulding time, product quality, product appearance, etc., and has a great impact on the quality.

The cooling system of the mold is the water channel, in other words, the design of the water channel affects the heat dissipation quality of the mold. The purpose of the waterway design is to make the product evenly cooled and ejected in a short period of time, the traditional mold cooling uses a simple way, mainly a straight waterway design, the production is simpler, but the heat dissipation time required is longer.

Comparison of special-shaped waterways with traditional waterways

Due to the advent of mold flow analysis software, designers can analyze the heat dissipation of molds and waterways through software, shorten the manufacturing time and improve manufacturing quality. Further, the design of the heat dissipation channel of the mold can also be designed with irregular shapes to improve the heat dissipation efficiency, which is the basic principle of the special-shaped cooling channel.

However, the method of making special-shaped waterway is limited by the existing technology, the way is to drill or cut and weld the mold, not only the construction is very complicated, but the life of the mold will also be shortened because of the secondary processing, so for a long time, the special-shaped waterway design can only stay in the theoretical stage, but after the emergence of metal 3D printing, these problems have been broken through.

Why has metal 3D printing changed the limitations of waterway design? This starts with 3D printing technology, 3D printing is a rapidly advancing engineering technology in recent years, the biggest advantage is that the principle of 3D printing is additive manufacturing, so there is no restriction on modeling, even if it is a complex shape and pipeline within the object, it does not constitute a difficulty for 3D printing, and the mold industry has noticed the value of 3D metal printing.

Whether it is the diameter of the mold waterway, or the internal corner processing that is difficult to be performed by the general lathe, metal 3D printing can be easily achieved, and even better, even if the planning method of the special-shaped waterway is complex, the metal 3D printing can accurately complete the mold and the special-shaped waterway at the same time as long as it is applied in one process.

The benefits brought by 3D printing metal conformal and special-shaped waterway molds, typical case analysis:

Mold design time reduced by 75%.

Manpower on the manufacturing side can be saved by 50%.

Save 14 injection mold production cycles.

Savings of 16% in manufacturing costs were achieved.

There is not much problem, because he is only used as a mold, and will not involve others, like the Aisky Storm S800 sand 3D printer has models of various materials.

The raw materials of metal 3D printing are mainly titanium alloys, aluminum alloys, stainless steels, high-temperature alloys, copper alloys, nickel alloys, etc.

Metal 3D printing technology is selective laser sintering technology, first complete the preliminary graphic design on the computer, in the 3D printer with a high-energy laser to melt plastic, metal or glass powder and other fine particles, so that it becomes the required three-dimensional shape of the slice, the sintering machine through the slices layer by layer accumulation, so as to obtain the required parts.

Copper, iron, steel, titanium alloys. Wait a minute...

As one of the more important components, metal 3D printing is often reused by many people.
