The fact that it can only print concrete and not steel bars is the most significant limitation of 3D printing concrete. Either start by printing the concrete and then inserting the rebar, or do it the other way around and start by printing the concrete and then adding the rebar. This is not too dissimilar from the conventional method that we use to construct. At this time, members of the international community have started investigating the possibility of producing such functional materials without the use of steel bars as supports. The solution at this point is nanoconcrete. Printing in multiple dimensions is also possible with this material, which works with the intelligent printing method that was just described. It is able to print a variety of forms to cater to individuals' specific requirements, accomplish three-dimensional printing in the air using the robotic arm, and more. In the event that these issues are resolved, it will be feasible for the house to have an irregular shape.

A house is a system that consists of many different structures and must go through many different processes before it is complete. Some of these processes include die casting defects causes and solutions waterproofing, insulating, decorating, and others. Figuring out how to combine them will enable the construction of the house to take place, which will bring us one step closer to the industrialization of the building process. When it comes to printing the house, the question of what kind of equipment to use takes precedence over everything else. Now, in order to build something using 3D printing, regardless of the size of the structure, it requires a portal frame that has a printing head attached to it. When printing with one layer and two layers, the structure can be seen through the frame that is created. The portal frame is very high, so you need to consider the mechanical possibility if you want to print high-rise buildings or print buildings that are taller than they currently are.

Casting and forging have a long history in China, going all the way back to ancient times. Casting is the first step in the production of an ingot, followed by the forging process. A single round of forging is not sufficient to complete the process; additional rounds are necessary. The grains can be made fine and uniform through repeated forging, which can also eliminate casting defects. The same is true of modern technology, and concurrently, in this process, continuous heating is required to ensure that the metal is in a state that can be forged.

The open processing method uses a lot of heat and is a method that produces a lot of pollution. Casting the material first and then forging it is a Metal Plating production method that is widely used all over the world. The process is very time consuming, repeated forging uses a lot of energy for heating, produces a lot of pollution, and because of the trend toward requiring overall lightweight manufacturing, it relies on very large forging machines that are continually growing in size (anywhere from 8,000 to 150,000 tons). The investment is very significant. To begin, the ingot needs to be cast, which involves including all of the dimensions of the part. Furthermore, in the final part, many parts need to be cut off, which is especially important in aerospace devices, which have a very low rate of material utilization. At the same time, a component needs to make use of a variety of materials in accordance with the functions it serves.

There is casting without forging, the performance and possibility are not as good as forgings, and it is difficult to suppress deformation and cracking when using 3D printing technology. This is the primary barrier preventing the widespread implementation of 3D printing technology in industry. On the other hand, the efficiency of the current process is inferior to that of the conventional one, and the price cannot be brought down.

Casting and forging need to be integrated into one process, and forging should take place while the material is still in the melting stage so that defects in the technology can be overcome. Changing the traditional domestic and foreign manufacturing methods that separate casting and forging is one way to do this. Forgings can be produced using a single piece of machinery, a metal wire, and a very low amount of pressure, resulting in a greener manufacturing process with fewer steps, a lighter workload for each machine, reduced energy consumption, and reduced waste. Conquer the challenge posed by the fact that traditional casting and forging cannot be digitally formed along the contour, and bring about the digital integration of milling, casting, and forging processes. Casting and forging that previously required a lengthy process and multiple devices can now be obtained with just one device that inputs wire. In the past, this was not possible.

In the traditional casting process, ordinary cast and forged parts have an extremely high risk of cracking during the cooling phase, and as a result, the yield is lower than 10%. Using such technology, it is possible to produce an item that is flawless in every way. The casting and forging techniques that have been refined over the course of thousands of years have been given a new lease on life thanks to the development of 3D printing technology.

The technology of 3D printing may also be used for the stamping mold of the automobile fender. This type of mold recognizes that the surface of the mold is mold steel, and that the majority of the interior is cast steel, which results in a significant reduction in cost; the majority of them use general materials, and only a few of them use good materials. Molds and valves, both of which make use of very expensive materials, have an overwhelming advantage in terms of competition simply due to the cost of the materials. The inherent crystals of 3D printing are transformed into fine crystals that are uniform and equiaxed, the shape and quality are created in parallel, and the performance is superior to that of traditional forgings.

The field of 3D printing is a technical one that is highly reliant on materials and equipment, and the growth of the entire industry is largely dependent on the ability to locate materials that are both less expensive and easier to work with. In the beginning stages of the growth of the industry, 3D printing should take a step back and concentrate on a few specific areas rather than trying to develop everything at once. At the same time, it is necessary to use industrial means to solve the problem of individualization in order for the 3D printing industry to be able to develop into a normal industry that has potential for growth. In conclusion, and most importantly, the development of 3D printing is still in its infancy, and effective standards have not yet been established in many different fields. This means that a certain amount of time is required to investigate and practice using the technology.
