3D printing is an additive manufacturing technique that involves stacking and fusing layers of material together, such as metal parts or plastic ones, to form functional objects. This process is used for fabricating both metallic and nonmetallic parts alike.
Technology is being applied in virtually every industry and classroom settings through printed dinosaur bones and robots, providing hands-on learning.
1. Reduced Costs
3D printing offers companies significant material cost savings. Compared with subtractive manufacturing techniques that require cutting, drilling and milling to remove material, which 3D printing does through layering powdered material like plastics, metals and ceramics into 3D structures resulting in lower raw material consumption resulting in decreased costs for production.
3D printers offer several advantages over traditional methods for producing parts: smaller batch production, less storage and transport costs, use of more cost-effective materials like ceramics compared to their steel and aluminium equivalents, lighter weight production volumes.
Industrial 3D printing helps companies reduce assembly costs with part count reductions and simplified geometries that improve functionality in final products. For instance, General Electric (GE) has used 3D printing to mass produce jet fuel nozzles with enhanced strength-to-weight ratios that have allowed mass production at scale; these could lower jig and fixture costs, worker ergonomics issues and improve efficiency – this trend being enabled by 3D printing technology in manufacturing supply chains.
2. Faster Production Time
3D printing technology offers faster manufacturing time because a new design can be printed and ready for use in hours compared to days or even weeks with traditional machining, speeding time-to-market and saving on tooling costs.
At the same time, 3D printing helps reduce inventory and supply chain costs as items are created as one piece instead of multiple pieces assembled together. This capability has proven particularly valuable to aerospace industries as they can use 3D printed parts such as blisks to lighten aircraft weight for fuel savings and reduced environmental impacts.
Companies can utilize 3D printers’ on-demand capabilities to produce units only when necessary, which is especially helpful when introducing new products into the market and can reduce risk. If engineers in plants around the globe need to use a fixture or jig that was developed somewhere else, this digital version could be sent digitally across the globe in hours at a fraction of the cost and with none of the paperwork associated with traditional shipping services.
3. More Customizable
Subtractive manufacturing uses machinery like milling machines to cut or hollow out pieces of metal or plastic; 3D printing lays down layers layer-by-layer. This allows designers to produce complex geometric parts using traditional manufacturing techniques – but creating them would not always be viable.
Once a design has been digitally modeled and “sliced”, its file is fed to a 3D printer which uses layers of wax or plastic-like polymer to build its final form step by step, providing almost limitless opportunities for customization of each individual part.
3D printing makes producing tailored products at scale possible for the first time ever, making a true revolutionary breakthrough possible. PepsiCo used one to quickly prototype different sizes of Ruffles chips before testing with consumers before rolling out its new designs. Furthermore, being able to print numerous items speeds up development cycles and shortens time-to-market by speeding time-to-market timelines.
4. Reduced Waste
Many 3D printers can print using recycled plastic, and replacing worn out parts of machines or vehicles means less waste in landfills and less energy required to build new ones.
Also, manufacturing sites located close to customers can reduce pollution-causing warehouses and shipping distances while cutting carbon emissions.
3D printing makes it easier than ever before to design products with minimal maintenance needs, thanks to its design freedom. This enables simpler assemblies using materials that are lighter and stronger than traditional components; plus it eases disassembly when replacing components, so the replacement process becomes faster and smoother.
3D printing allows companies to manufacture items locally, which reduces shipping and handling costs as well as carbon emissions by eliminating the need to fly, drive and ship products across oceans or continents – an invaluable advantage for organizations striving to become more eco-friendly. This represents an incredible advantage to those striving for greater sustainability.
5. Increased Flexibility
Additive manufacturing, commonly known as 3D printing, involves creating objects by layering material to them layer by layer. As opposed to subtractive methods that remove material from blocks in order to form shapes, 3D printing builds objects by depositing materials according to computer files deposited from layer by layer. This technology has launched a manufacturing revolution enabling almost anyone to become their own manufacturer.
Plastics and metals are among the most frequently utilized materials for 3D printing; however, there is a diverse selection of other options that include water-absorbing resin to nitinol for strength and heat resistance, to gold for heat resistance. This versatility also enables companies to print parts with specific properties like increased fuel efficiency or weight reduction that cannot be accomplished using traditional manufacturing processes.
3D printing offers businesses increased responsive design capabilities, allowing them to adapt designs as soon as inspiration strikes or customer feedback surfaces. This enhances innovation while decreasing risks associated with mass production processes and production delays. Printing also allows businesses to quickly produce prototypes compared to conventional production methods reducing lead times significantly.
