Wohlers Associates helps organizations take advantage of technologies and strategies that enhance the rapid product development and manufacturing process.
Government officials have been asking how 3D printing will create jobs in their part of the world. The subject came up again last week in Melbourne, Australia when meeting with people at the state government of Victoria. We explained that some companies and businesses would not exist if it wasn’t for 3D printing. An example is Align Technology, makers of the Invisalign plastic aligners that replace metal brackets and wire to straighten teeth.

Align takes advantage of additive manufacturing to produce parts used to thermoform sets of custom plastic aligners. The company involves many additional processes, including CT scanning, special software, 5-axis CNC milling, robotics, polishing, and other methods of manufacturing and packaging. Seeing it in action is impressive. Much of it involves a great deal of sophisticated automation, which has dramatically reduced manual labor, but has also created many jobs. The company employs 3,580 people. Consider also all of the people needed to design, produce, sell, and service the machinery and systems that make everything tick at the company. And, consider the many dental professionals that are impacted by the Invisalign product.
As 3D printing penetrates production applications more deeply, it will involve many upstream and downstream processes. Among them: new methods of design and redesign, data management and IT, and cloud computing and web services. Also, it will involve thermal processes and machining operations, materials and material handling equipment, surface treatment and methods of coating, and inspection and process improvement. Consider all of people and jobs behind these machines and processes.
3D printing is what made it possible for Align Technology to create personalized plastic aligners. It is the enabling technology that will help launch many other new companies and businesses. Organizations of all types and sizes will put 3D printing to work to manufacture custom, limited edition, and even relatively high volumes of products, especially in the future. When viewing it from this perspective, it will create many jobs. A manager at GE put it best when he said, “Additive manufacturing won’t create thousands of new businesses; it will create tens of thousands.” And, behind them will be countless jobs.
