3D printing has transformed the aerospace and automotive industries, helping companies design prototypes. While it was limited to specific sectors, 3D printing in logistics has caught the attention of business entrepreneurs.
Components manufactured with 3D printing machines mimic the properties of manual systems. This helps companies cut production costs as they stop relying on outsourcing. Let’s understand the nitty-gritty of 3D printing and its exciting possibilities in the supply chain industry.
But, first, understand what 3D printing technology is.
What is 3D printing?
3D printing, also known as additive manufacturing, is the process of creating three-dimensional objects from a digital model by layering materials atop each other. Unlike traditional manufacturing, 3d printing creates objects layer-by-layer allowing complex designs and shapes.
3D printing in logistics has caught significant attention because it shapes innovative ideas. Here’s how this printing technology works.
- Model Design – The process starts with using computer-aided(CAD) software. The digital models are downloaded from online repositories.
- Slicing – The digital models are ‘sliced’ into thin layers using slicing software. This slicer creates the instructions the printer will follow to create the visual model.
- Printing – The 3D printer follows the instructions layer by layer, depositing materials like resin, metal, plastic or even biocompatible substances until the final object is built.
- Post-Processing – Once the printing is complete, the object may require curing, cleaning, or additional steps based on the material used.
Next, let’s focus on the types of 3D printing in logistics technologies.
Types of 3D Printing Technologies
3D printing has different technologies suited for different functions based on material, object size, and precision. Here are the main technologies fueling the growth of logistics and other industries.
1. Fused Deposition Modeling(FDM)
FDM, also known as Fused-Filament Fabrication(FFF), uses a computer-controlled extrusion head to deposit a thermoplastic filament in layers to create a 3D object. It heats the filament through a nozzle, moving in a pre-programmed pattern to layer the material step-by-step to create an object.
This 3D printing in logistics method is ideal for prototyping and developing functional parts for low-cost manufacturing.
2. Stereolithography(SLA)
This is a technique to create three-dimensional objects, using computer-controlled laser beams. The 3D printing in logistics method uses a UV laser to collect liquid photopolymer resin in a vat. The laser draws the object layer on the resin’s surface, hardening it.
The models are created using photochemical processes through which light causes chemical monomers and oligomers to cross-link together to form polymers. Complex prototypes, highly detailed models, and jewelry pieces are manufactured through SLA fabrication.
3. Digital Light Processing(DLP)
Similar to SLA 3D printing in logistics, DLP uses a digital light projector to cure liquid resin. The projector flashes the light immediately making it a faster alternative for printing materials than SLA.
DLP uses an arc lamp rather than a laser beam, to cure the entire layer at once. The DLP machine runs on DLP chips – precision devices made of millions of microscopic mirrors to reflect the image. This machine is suitable for injection moulding, thermoforming, and building assembly components. DLP products design intricate details previously considered impossible.
4. Binder Jetting
3D printing has reached the stage of advanced technology in logistics, with binder-jetting being a prime example. It involves depositing a liquid-binding agent onto a bed of powder( usually metal, ceramic, or sandstone) layer by layer. The roller spreads the powder and the process repeats till the object is built.
The printed components go through a process called infiltration to fill the void left by the binding agent. The powder needs to achieve high density to strengthen the object material.
Now, let’s move to the recent innovations shaping 3D printing in logistics industries.
5 Ways 3D Printing Will Change Logistics
The long-awaited trend of printing digital models is moving into the mainstream supply chain sector. Let’s look at its immense potential in the coming years.
1. Mass Customisation and Decentralized Production
Major industry players are investing in 3D printing in logistics technologies. The disruptive nature of 3D printing shouldn’t be underestimated because the trend of customisation is gaining record pace. The future belongs to customised designs as manufacturers won’t keep large volumes of standardised products in stock.
Instead, they will opt for flexible manufacturing based on the “made-to-order principle” to accommodate customer order requests.
2. The Initial Increase in Last-Mile Shipping
Many experts predict localised production sites will gain importance in the coming decades. The volume of custom manufacturing will grow and 3D printing in logistics will get closer to the customer with goods no longer requiring to be shipped halfway around the world. This means last-mile shipping will boom as people will want 3d printed materials delivered straight to their home.
3. Warehouse Optimisation
3D printed models lower logistics costs and shorten delivery time by bringing the product closer to the final point of use. Additionally, warehouses can store digital designs instead of physical inventory, reducing storage space. Companies can customise products and quickly adapt to changes in demand.
4. Sustainable Production Processes
Unlike traditional manufacturing techniques, the future of logistics technology will change due to 3D printing. Companies will eliminate mass-production and excess inventory, minimising waste and overutilisation. This will encourage widescale adoption of sustainable practices in the supply chain domain.
5. Spare Parts and Reverse Logistics
Companies no longer need to hold large inventories of spare parts, printing goods on demand to reduce spoilage and obsolescence risk. This is highly useful in aerospace, automotive, and machinery supply chains.
FAQs – 3D Printing in Logistics
How is 3d printing used in logistics?
Printing materials on demand will give companies the flexibility in managing supply chain, optimizing storage space, and achieving shorter storage lead time. This is done through customized 3D printing solutions for printing precise and detailed components.
What is 3D logistics?
This refers to the integration of 3D printing into supply chain operations, transforming how goods are produced, stored, and delivered in the supply chain ecosystem.
How 3D printing works?
Three dimensional printing creates a 3D object from a digital design. The machine layers down thin materials in liquid or powdered plastic/metal/cement and binds them together.
What material is used in 3D printing?
3D printing materials vary widely with options including plastics, resins, rubber, metal, and carbon fiber. These materials are easily customisable, durable, and are promising options for many parts, from aerospace and industrial machinery to customer goods.
What are the advantages of 3D printing over traditional manufacturing in logistics?
3D printing offers advantages such as reduced production lead times, cost-effective manufacturing, on-demand production, and the ability to create highly customized products. It also minimizes waste and lowers the need for physical inventory storage.
How does 3D printing impact supply chain efficiency?
By decentralizing production, 3D printing improves supply chain efficiency by reducing transportation costs and lead times. Digital inventories allow companies to produce goods closer to demand points, streamlining operations and cutting down on logistics expenses.
What are the challenges of adopting 3D printing in logistics?
While 3D printing offers significant benefits, challenges include high initial setup costs, limitations in material variety and strength for large-scale production, and the need for specialized skills to operate and maintain 3D printers.
How does 3D printing contribute to sustainability in logistics?
3D printing reduces material waste, promotes energy efficiency, and supports local production, thereby decreasing the carbon footprint associated with global shipping and traditional mass manufacturing.
Conclusion
The integration of 3D printing into logistics has opened up exciting opportunities for businesses to rethink their supply chain strategies. By enabling decentralized production, mass customization, and on-demand manufacturing, 3D printing transforms how goods are designed, produced, and delivered. Companies benefit from reduced inventory costs, optimized warehousing, and faster response times to customer demands.
