A few days ago, John Hart, an associate professor at the Massachusetts Institute of Technology and founder of Desktop Metal, said at the MIT Technology Review that 3D printing has broken the boundaries of plastic toys and is part of the entire product lifecycle. Hart also said that 3D printing is omnipotent, from product conception and sample trial production to final unit production.
3D printing, also known as additive manufacturing, is currently being used in all stages of the product life cycle and in various emerging industries. According to Hart, widespread use is evidence of technological maturity. He has witnessed the successful manufacture and sale of 3D printers by large companies such as Hewlett-Packard, which uses the technology to break the existing supply chain and aerospace companies to use 3D printing to manufacture product parts.
Previously, we traditionally believed that some industries are suitable for 3D printing products, but the use of 3D printing has long been more than that. “Lesson's potato chips use the lowest cost printer to print potato chip geometry samples,†Hart said. “They said that the delivery of potato chips to customers has increased confidence in expanding production.†Although the company is likely to remain Staying in the production of samples, but companies like Bugatti and Chanel have already started using 3D printing to mass produce products.

Hart predicts that 3D printing devices will be fully automated in the next three to five years.
Slow production speeds make people reluctant to use 3D printing, but Hart Labs made great strides in speeding up printing last year. Innovations in real-time sample production rather than rapid sample production have had a profound impact on engineering development, maintenance intervals and emergency operations.

Duplex Stainless Steel Overview
Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.
Today, modern duplex stainless steels can be divided into three groups:
Lean Duplex such as LDX2101
Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex usage
Super Duplex such as Ferralium 255 and Zeron 100 and LDX2507
Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
