3-D printing has moved far beyond prototyping, rapid tooling and trinkets. Companies like GE, BMW and Honda are now using metal 3D printing services for industrial production.
Exorbitant lead times are not good for lean operations. However, producing parts on-demand with 3D printing eliminates a step in the process and can reduce lead times by weeks.
1. Rapid Prototyping
The prototyping phase of product development is a critical stage in the design and production process. It allows teams to create physical prototypes of their digital designs, executing quick revisions based on real-life testing and analysis. This helps teams develop more user-friendly products that are ready for market faster than ever before.
Prototypes can range from rough paper sketches to interactive simulations that look and work like the final product. The key to a successful prototyping phase is focusing on customer pain points and issues. This can be done through research, previous support tickets, or even through a customer feedback platform. Once the team has a good understanding of what users need, they can start creating high-fidelity prototypes and simulations that will allow them to get valuable user feedback.
3D printing enables rapid iteration of prototypes with the ability to produce multiple iterations quickly and inexpensively. This makes it easier to test for fit, function, and manufacturability. This can help eliminate costly tooling and save time in the production process by allowing engineers to make changes before investing in full scale manufacturing. It also enables part consolidation or amalgamation, where parts that would have needed to be welded, bonded, or attached with fasteners can be printed as one finished piece. This reduces assembly costs and weight while improving durability. 3D printers offer a wide variety of materials and finishes to meet all needs.
2. Enhanced Design Flexibility
The design flexibility of 3D printing lets companies make a wider mix of products, and optimize the supply chain to minimize tax and tariff costs. In addition, manufacturing localized parts based on the customer demand reduces shipping costs.
This is why many manufacturers are embracing MaaS (Making as a Service) business models that offer an in-house fleet of 3D printers to produce high-quality components on demand. This eliminates the need to invest in costly new equipment that could rapidly become obsolete, and it allows manufacturers to shorten the lead times between a product’s final design and its delivery.
3D printing also helps streamline production by reducing the number of individual parts that are needed for a single item. This makes assembly much faster and simpler, while also reducing maintenance costs. It can even be used to print jigs, molds and other fixtures that are typically produced in multiple steps, such as CNC machining, to streamline repair and increase productivity.
This is also why a company like Local Motors was able to print a good-looking roadster (including wheels, chassis, body, roof, interior seats and dashboard, but not the drivetrain) in just 48 hours. And with the rapid evolution of materials science creating new, printable substances, it is not unreasonable to imagine a future in which we print entire cars from a single machine. Similarly, this process could be used to print concrete buildings that are more durable and cost-efficient than traditional methods.
3. On-Demand Production
When manufacturing on demand, businesses are able to produce parts and products that match customer specifications exactly. This eliminates the need for costly tooling and reduces production lead times. It also minimizes the need for inventory storage and distribution, reducing logistics costs. It's the ideal solution for companies looking to improve their bottom line and stay ahead of the competition.
On-demand manufacturing has already begun to disrupt the traditional economy in several ways. For example, a company called Winsun is using 3D printing to build houses, allowing people who can’t afford to buy traditional homes to live in them. In addition, a startup is developing 3D printing technology that is 10 times faster than current metal printing processes. This could allow for on-demand production of metal parts and components for vehicles and other large industrial equipment.
3D printing is already widely used in industries such as aerospace, automotive and healthcare. It can help create components with complex geometries that are difficult or impossible to produce with traditional methods. It can also enable the consolidation of multiple parts into a single component, resulting in weight savings and shortened design and development cycles. In the field of medicine, hearing aids and prosthetics have been produced on-demand using 3D printing, saving both time and money. One such organization, e-NABLE, has created over 8,000 free prosthetic hands for people around the world.
As on-demand manufacturing continues to grow, companies will need to develop new digital platforms that can support the entire process. These platforms will need to enable design sharing, fast downloading, and quality control. They will also need to orchestrate printer operations, ensure consistency, and provide real-time optimization of printer networks.
4. Customization
As the industry evolves, manufacturers will increasingly be expected to deliver personalized products. This requires them to structure their production processes for small batches and one-offs where they were previously structured for mass production. This shift is difficult, especially when these small batches need to be manufactured in the same amount of time as a product they would make through traditional manufacturing.
3D printing services can help. They can eliminate tooling costs and allow for multiple design variations to be produced on the same machine without retooling. This enables supply chains to be more agile and resilient, and accelerates time to market.
Consumers can also benefit from customization as it creates more of a sense of ownership and belonging to the end product. For example, 3D technology has helped to revolutionize the $271 billion toys and games industry by allowing for custom toy printing, either from companies looking to differentiate themselves or by savvy consumers with a home printer.
5. Cost-Effectiveness
The use of 3D printing services helps reduce the overall manufacturing/production cost. This is accomplished through a number of ways, but they can be boiled down to three key advantages: zero tooling costs, lower part complexity and reduced labor costs.
3D printers are able to produce parts that would be difficult or impossible to manufacture using traditional methods. These include part consolidation and the ability to eliminate fasteners. This can lead to a significant reduction in assembly time and costs. 3D printing also allows for a significant reduction in the weight of the finished product. This can help lower shipping costs and improve fuel efficiency.
In addition to reducing costs, 3D printing also enables a significant increase in productivity. This is achieved through part consolidation and streamlined processes. It also enables companies to produce a large number of different products within the same location. This can help to lower production and shipping costs, as well as enabling faster response to demand fluctuations in the supply chain.
Finally, 3D printing can also help to reduce operating expenses by eliminating the need for a large human workforce. This can lead to a reduction in labor costs and can also help to avoid the need for costly relocations of manufacturing operations. This could have important implications for countries that rely on cheap labor for their economies, but it may also provide opportunities for them to create new forms of economic value-production.
6. Reduced Waste
While 3D printing is not only revolutionizing full-scale production, it’s also reducing waste in the form of material, labor and time. The use of 3D printers eliminates the need for traditional assembly line tooling, which reduces manufacturing costs and speeds up production times. Additionally, the ability to print on demand eliminates the need for inventory or storage space and allows for rapid repurposing as market demands change.
The use of 3D printing technology has given schools a leg up when it comes to STEM education, with students using 3D printers to design and print their own creations. Teachers have been using the technology to incorporate innovative designs into lesson plans and encourage creativity in the classroom. The ability to print in multiple colors and materials gives teachers the opportunity to add visual elements to lessons that can reinforce core concepts while engaging students.
Many companies are taking advantage of the speed and agility of 3D printing by outsourcing their manufacturing needs to service providers. This allows them to focus on core competencies and eliminates the risk of having to keep up with ever-changing technology and obsolescence risks.
The healthcare industry has found a variety of uses for 3D printing services as well, including the printing of prosthetics. For example, the e-NABLE community has printed more than 8,000 prosthetic hands and arms for those in need. Additionally, dental tools that have traditionally been hand-carved can now be printed, saving time and money for dentists.
