#19 - 3D Printing
Prototyping with traditional manufacturing methods takes time. Molding and casting are most cost-effective with larger volumes. New parts require major changes in tools, molds or dies.
3D printing enables rapid prototyping, single-step manufacturing and complex, almost unrestricted designs. 3D printing has developed from a hobby to a serious alternative in industrial manufacturing.
Familiarize yourself with the 2 branches of 3D printing: consumer vs. industrial.
Start a 3D printing shop. An entry-level printer costs anywhere between $200 to $1200. Filament can be as cheap as $25/kg. The consumer printing industry repeatedly reports profit margins ranging between 70-90%.
Carbon - Industrial 3D printers.
ICON - Printed homes.
Desktop Metal - Metal and carbon fiber printing.
ExOne - Metal and sand 3D printers.
Hubs - 3D printing as a service.
The real value of 3D printing is in the ability to create parts that no other manufacturing method can. It boosts the freedom of design. Other key benefits:
Manufacturing components on-demand.
Strong and lightweight designs.
The possibilities in different industries are endless: aviation, medical, automotive, construction, robotics, entertainment and more. 9 Fortune 500 companies that are pioneering the use of 3D printing.
Biggest drawback of 3D printing is still the high price with higher volumes. Standard parts will continue to be made with traditional processes, such as injection molding and urethane casting.
