Will it disrupt supply-chain logistics and delivery?
3D printing (also known as additive manufacturing) is a computer-controlled process that, using a 3D printer, creates three-dimensional objects from a digital design template and layers of material. This process can produce complex, integrated designs in a one-step process without extra tools or molds, potentially reducing the cost of manufacturing and need for extensive assembly work. A single 3D printer can produce a theoretically infinite variety of designs depending on the capabilities of the printer itself (e.g., size and type of material).
Applications of 3D printing fall into two broad categories: consumer and commercial. Consumer applications at present have tended to focus on making gadgets for hobbyists. The relatively high cost of a consumer 3D printer ($1,500 to $2,000 on average) has thus far limited individual ownership to select hobbyists and enthusiasts. However, the variety of consumer applications is continuing to increase. Some current applications include:
- Customized household items like containers, hooks, and cooking utensils
- Mattel & Autodesk’s allows children to design toys
- Customized jewelry and fashion
- Diverse novelty items such as camera and watch components, musical instruments
Fueling the increasing variety of designs are online platforms such as Thingiverse and Pinshape that share open source digital designs. In addition, there are a growing number of brick-and-mortar fabrication shops (“fabshops”) in urban areas that offer 3D printing access to a wider audience of people through collective use.
Commercial applications initially focused on rapid prototyping and proof-of-concept for manufacturing. However, the commercial applications have evolved to include more complex applications such as:
- Parts manufacturing (e.g., Mercedes-Benz Truck, BMW Group, GE, Airbus)
- Consumer goods production (e.g., Adidas 3D-printed sneakers)
- Individualized healthcare products (e.g., prosthetics and orthotics)
- Automobile manufacturing (e.g., Local Motor’s electric car “Strati” and self-driving electric shuttle “Olli”)
- Delivery drone production (e.g. Amazon)
Possible Impacts on Transportation Planning
Increased commercial and consumer 3D printing use could result in a number of potential benefits and drawbacks related to transportation and travel. Possible benefits include:
Increased local, decentralized production of goods, “just in time” inventory management, and on-demand goods production.
Decreased air pollutant emissions associated with fewer long-distance delivery vehicle trips
Decreased long-distance vehicle trips and vehicle miles of travel due to more localized delivery and a shorter supply chain,
Decreased roadway maintenance costs associated with fewer long-distance delivery vehicle trips
Increased roadway capacity and reduced vehicular delay associated with fewer long-distance delivery trips
Decreased conflicts at at-grade railroad crossings associated with fewer long-distance rail delivery vehicles
Possible Limitations on Transportation Planning
Possible drawbacks of increased 3D printing that relate to transportation include:
Increased shorter-distance vehicle trips and vehicle miles of travel associated with local deliveries of raw printing materials to more, decentralized manufacturing facilities or with increased 3D printing at home
