Industrial Application Of Artificial Intelligence In 3D Printing

The field of additive manufacturing is expanding rapidly, with new materials, technologies and solutions constantly being developed. From identifying the best material for a job to improving the quality of a product’s build by eliminating human error, machine learning (ML) is playing to its unique strengths.

Before a 3D printed object can be used for real, it must be repaired to eliminate holes and other defects, which often requires a lot of manpower and material resources, but now these difficulties can be automatically identified and solved by ML, saving time and money, because It eliminates the need to reprint the entire product or spend hours manually repairing each component. By making small changes based on experience, machine learning can be used to optimize the design, maximizing high-quality output. Predictive maintenance uses ML algorithms to be able to predict when parts will need to be replaced or repaired before they fail completely, helping to organize plans and avoid costly repairs or downtime while waiting to replace components. Using machine learning, companies can leverage consumer data to create goods that meet their needs. In short, AI and ML have several advantages when used in conjunction with 3D printing.

1.AI fault remote monitoring

Detecting failures during 3D printing is essential. The journal Processes describes a novel AI-based computer vision method for evaluating the quality of fused filament fabrication (FFF) 3D printing projects during the printing process.

By analyzing video captured during the process, a neural network is built to spot 3D printing issues throughout the printing process. During the printing process, 3D printed items are likely to have defects, such as stringing. These defects are usually associated with one of the printing parameters or the geometry of the object. In this case, an AI framework (Deep Convolutional Neural Network) is developed and implemented in a real-time environment to perform the detection process and prediction on the live camera stream.

2.How AI-enabled 3D printing is shaping the future of orthodontics

Similar to other industries, innovative digital technologies have transformed the healthcare industry and orthodontic practice. Recent breakthroughs in artificial intelligence (AI) and 3D printing technology have important implications for enhancing orthodontic diagnosis and treatment planning, as well as building algorithms and manufacturing personalized orthodontic products.

Artificial intelligence holds great promise for diagnosing dentofacial abnormalities and designing orthopedic surgical procedures. A convolutional neural network approach showed that orthognathic surgery significantly improved the appearance and aesthetic appeal of most patients. AI technology improves clinical accuracy in orthognathic surgery, treatment planning using 3D models (3D fabrication of surgical orthoses), as well as treatment follow-up and picture overlay.

3.AI-based printability inspection

In theory, the 3D printing process is capable of creating any 3D object. However, compared with traditional production processes, the development and utilization of 3D printing is still limited due to its topological properties and special material requirements. A recent article in the Journal of Basis Applied Science and Management System introduces readers to the Printability Checker (PC) program, which determines whether an object is suitable for 3D printing or other production methods.

It consists of Feature Extractor (FE), Printer Manager (PM) and Validator Engine (VE). The PC makes judgments based on the result of the standard complexity value. Computational complexity depends on the choice of several metrics, such as the running time of the tests. Specifically, the goal of finite elements is to retrieve scientifically testable characteristics of a given 3D object. The PM is responsible for managing the printer with the applicable restrictions and then sends the printer configuration file to the VE. At the same time, VE can match the characteristics and limitations of FE and PM, and verify the printability of 3D objects according to the final complexity results.

4.How will artificial intelligence affect 3D metal printing of aerospace parts?

Journal of Physics: Conference Series includes an article on the integration of artificial intelligence in 3D metal printing has been seen as a potential development and thus a basis for technological advancement in aerospace. 3D printing combined with artificial intelligence is enabling aerospace manufacturers to produce more accurate and precise aerospace parts at lower cost and with less waste, with increased design freedom. Sensors and cameras are installed within the 3D printer, usually near the nozzle where the powder feedstock and laser beam combine to form a solid layer, to provide process control and monitoring. The data is then sent to specialized software that evaluates and interprets various phenomena in real time, recognizing problems and harnessing the power of artificial intelligence to solve them.

Challenges of Artificial Intelligence in 3D Printing

Data-driven numerical simulations are known to be computationally more efficient than physics-based numerical simulations using ML methods. In situ analysis and closed-loop regulation are highly computationally dependent. Inspection of pools with high-speed cameras requires more processing resources due to the larger dataset. Such applications using large data collections require improved machine learning algorithms. Computational cost is a significant barrier to implementing AI in additive manufacturing.

Data exchange is critical to the development of the large databases required for ML algorithms to function. As more research groups focus on the creation of novel materials and processes, standards for data collection and preprocessing will ensure data sharing and foster collaboration within the AM community. Many ML frameworks are not compatible with each other. In order to disseminate ML models in the research community, it is crucial to have a consistent framework. The lack of standards is a major problem that requires immediate action to address it.

The performance of machine learning (ML) algorithms is only as good as the quality of the input data. Sensing devices used in 3D printing processes involving fusion processes must have fast refresh rates and excellent resolution in order to gather information from the melt pool. Despite the wide variety of sensors used, each field monitoring method has limitations that hinder its application in actual production lines.

The Future Outlook Of AI 3D Printing

Artificial intelligence is providing advantages to the additive manufacturing industry, and future research should focus on:

  • Incorporates AI-based printability testing, slicing, and route planning to accelerate parallel slicing and optimize 3D printing paths.
  • Use a service-oriented architecture (SOA) to improve the adaptability, integration and personalization of 3D printing through a cloud-based design and production system.
  • Improving ML-based computational prefabrication (process planning) through exponential techniques, parallelization, and improvements in slicing algorithms, further opening the way for rapid global industrialization.

In short, the intersection of artificial intelligence and 3D printing has become a recipe for success, with institutions all over the world investing in this particular field.
