3D printing is also called as additive manufacturing technology. This technology has gained high popularity recently because of its applications. this has potential in every industry like health, manufacturing, toys many other fields.
This is mainly used for prototyping in the initial days, but now the whole product is manufactured by this technology. materials like plastic and metal can be used in this technology based upon our requirement in a filament form.
The process of 3D printing is creating a three-dimensional object from the digital designs using the required materials by adding layer by layer. There are different benefits of 3D printing. It can make easy and very complex 3D objects without any wastage.
Some of the significant issues in 3D Printing
One of the main issues with this technology is the high cost.it is a very high-cost technology in printing and object. The price of the 3d printing machines is very high for a small 5×5 feet device, costing nearly 30,000 to 50,000.it may go higher with some added features.
Not only the device but also the material which is used in the 3D printing technology are more when compared with the traditional manufacturing materials. with high usage, the 3D printers’ price has been coming down in recent years, but the high quality and accuracy machine is costing very high.
The materials used in the traditional method are very high, with different compositions and grades. But in the case of 3D printing, the availability is materials is minimal. The range of the materials is very comparatively significantly less.
This is making a challenge to produce 3D-printed objects with specific materials to meet the existing. For example, to manufacture a high-strength thing that should be able to load high weights or them, high-strength and flexible materials are required. Some of the materials are very expensive and very difficult to get in the industries.
Material Limitations in 3D printing for industries
Quality Control Issues:
Quality control is the central part of the manufacturing industry whereas in the case of 3D printing, it is essential than traditional methods. this technology produces different quality control issues in the case of complex objects with high precision.
The process itself will create many quality control issues such as when there are imperfections and errors in the design, the machine will not place the material layer by layer at the required position, which results in a defective object.Many industries require very high precession and consistency, such as aerospace and medical manufacturing, where the products should meet the desired conditions without errors.
To solve this issue, every industry should implement testing and inspection methods in their manufacturing process to ensure that every product meets the requirements. By implementing robust quality control processes, manufacturers can ensure high-quality objects as end objects.
This is one of the major problems in 3D manufacturing .it can produce good quality and complex objects but take more time when compared to the traditional manufacturing .
To print a single object may take hours in some cases, it may take days based on the complexity of the object and size.
this is the reason many industries which require high volume in less time are not adopting this technology.
Not only does the print process take time to select the suitable material, but preparing the printer also involves a time taking approach.Many researchers are developing to increase the speed and efficiency of 3D, such as multi-materials printing, continuous printing, and high-speed printing.
Impact on the Environment:
The materials and energy required to operate the machines have a high impact on the environment .many materials we use in the 3D print are not biodegradable, contributing to the plastic deposits on the earth, which will affect the environment.
Other than this, the energy required to operate the machines is also affecting the environment. When printing complex shapes of large sizes, it may take even days for this continuous electricity to be needed.
by developing more sustainable materials which do not affect the environment and energy sources such as solar energy have been used to run the machines. By making many changes also, the impact on the environment remains a concern.
Surface finish is also an essential factor in manufacturing .with the traditional method, we can get an excellent surface finish but in the case of 3D printing, the surface finish is not up to the required standards of the industry.
After this process, the extra materials should be removed from the surface and finish processes such as roughing or smoothing .
With a small machine we cannot print large 3D objects based on the size requirement we need to get the device.As we increase the object’s size, the time and complexity will increase parallelly.
To overcome this issue in 3D printing, many companies have started exploring new technologies to print large objects .one such technology is “gantry Printing,” which uses robotic arms to place the material, which allows making large 3D objects.
Intellectual Property Concerns:
Making replicas with this technology is very easy compared to other .scanning the object, creating a digital image, and printing with the 3D machine is very easy.
This has led to concerns about protecting IP rights, mainly in industries where intellectual property is one of the critical parts of the business model.
3D printing has many benefits in creating complex shapes and designs .it also have a share of problems that make it challenging for industries to adopt this technology. challenges like High Costs, Limited Materials,
Quality Control Issues, Slow process, Impact on the Environment, Surface finish, Size limitations, and Intellectual Property Concerns are some major problems in this tecnology. Many others are less significant than these.
Much research is underway that will address these challenges which are including the development of new materials for 3D desing and new technologies. As these efforts continue, 3D tecnology will become a high-value and widely adoptable technology in manufacturing.
What is the problem with 3D printing too fast?
if a 3D printing machine prints slowly then the design will not comes with accuracy, so printing fast makes printer to print the design with 100% accuracy
