3D PRINTING – Eliminating Wastes and Reducing Carbon Footprint by Abhilasha Satpathy, DCMME Center Graduate Student Assistant

The economic advantages of metal additive manufacturing as an alternative to traditional methods are clear, but the reduced environmental impact may be even more important to the future of industry.

Shipping: An Enormous Carbon Footprint

The flow of raw materials into a manufacturing facility and finished goods out of it require enormous energy inputs allocated to shipping. Given that traditional manufacturing has been heavily reliant on fossil fuels since the Industrial Revolution, this process exacts a major toll on the environment. Together, the transportation sector accounts for over 30 percent of all U.S. emissions. Industrial transportation related to shipping undoubtedly comprises a major segment of this total.Complex, disjointed supply chains result in an end-use product that requires inputs to be shipped from hundreds of suppliers. Further, the completed product goes through multiple layers of distribution before it arrives in its buyer’s hands. 3D printing can’t fix all these problems, but it does have the potential to dramatically cut the number of links in the chain by allowing local, on-demand manufacturing of a huge variety of components. Without a doubt, 3D printing will eliminate millions of component shipping journeys in the coming decade.

Traditional Processes Waste Vital Resources

The largest segment of the metal parts fabrication industry is “subtractive” processes like CNC milling, in which material is cut away from a block to produce a final part.This brings us back to the key word, “subtractive.” The problem with this type of manufacturing is that any of the original block of metal that is cut away is waste. That wasted material represents additional resources that must be extracted from the Earth via potentially harmful mining practices.

Even worse, the final outcome for the scrap material itself involves one of two things:

  1. Additional shipping and processing to take advantage of whatever economic value the cast-off still has
  2. A trip to the local landfill, where industrial overcrowding is already a significant issue

Metal 3D printing, when economically viable, provides a nearly perfect solution to this problem. Because it’s an additive process, whereby material is layered onto itself in an exact pattern, there is virtually no waste associated. Only the metal that actually comprises the final component is used. The unused material can be recycled.This could mean the difference between 95% waste with CNC machining and < 1% waste using metal AM.

Toxic Byproducts are Common in Metal Manufacturing

Certain types of metal manufacturing, most notably CNC machining and metal injection molding, require the use of toxic substances as part of their process. The oils and lubricants needed to ensure CNC machines run properly are often dangerous to the environment. The finishing process for these parts can also make use of fluids that can be damaging if handled incorrectly. These must be handled carefully and disposed of properly.Needless to say, “properly” isn’t a standard to which all manufacturers worldwide are held. Some percentage of the harmful agents used in both CNC machining and metal injection molding will make it into the air, water, or soil that supports the community around a plant. It’s hard to quantify this, but the environmental impact is real.Standards for proper disposal of hazardous chemicals associated with conventional metal manufacturing can vary dramatically by world region.

Metal AM eliminates this concern entirely. The process simply doesn’t generate any toxic byproducts, which guarantees that air and water quality won’t be directly harmed.Conventionally made components can leave a much bigger carbon footprint than 3D printed parts.A less obvious environmental cost of traditional manufacturing lies in the efficiency of end-use products. Recent successes in metal 3D printing have changed what’s possible for fuel efficiency in a variety of places. The technology has enabled huge design improvements that shave off weight without compromising strength.

Lessening the Carbon Footprint Through AM-Enabled Design

3D printing allows for the manufacture of parts with complex internal geometries, often in ways that are impossible for conventional techniques to match. The upshot is that design changes that combine multiple parts into a single component can often be completed without sacrificing functionality–or feasibility. This accomplishes the goal of lowering cost and lead times by simplifying the manufacturing process, but it also comes with significant environmental advantages.

Additive Manufacturing Optimizes Designs & Efficiency

As the world marches toward an increasingly tenuous climate future, the costs of a suboptimal part made through traditional manufacturing must be considered right alongside the more tangible impacts described above. There are countless heavy or less-than-aerodynamic components in applications across every sector that could be improved significantly with the design freedom afforded by metal AM. In aggregate, the emissions reductions that are now feasible through projects like GE’s Advanced Turboprop engine would represent major improvement for humanity’s overall carbon footprint. Metal 3D printing doesn’t yet offer all the answers, but in a growing percentage of manufacturing situations, it’s a step in the right direction for our planet.

How Augmented Reality is disrupting supply chains. – Abhilasha Satpathy

With over one billion AR enabled smartphones and tablets already in use, companies don’t have to wait for low-cost augmented reality glasses to start reaping the benefits of augmented reality. Here are five ways that AR is transforming the supply chain into a nimble tool for global distribution:

1) Pick-and-Pack Services

Augmented reality is being used in warehouses to more efficiently locate products and pack them in outgoing boxes. One of the costliest parts of running a “pick and pack” service is training new workers to navigate a large warehouse and find the one product they are searching for. AR glasses can paint an imaginary line on the warehouse floor to simplify the searching and training. During the peak holiday season, temporary workers need to be on-boarded quickly. AR shortens the learning curve by providing new hires with constant feedback on their glasses about how they are doing and what can be improved. Field tests of AR pick-and-pack systems have reduced errors by as much as 40%.

2) Collaborative Robotics

Robots are the ultimate human augmentation. Workers sitting comfortably at their desks can wear AR glasses that let them see what a robot in the warehouse sees. AR glasses can now chart the paths of robots through warehouses and use their strength to lift and move heavy cargo. Dangerous or repetitive tasks, such as loading a truck, can be delegated to robots that operate with human guidance when it comes to how to best load the items to achieve the maximum load. Additionally, logistics robots are able to scan each product for damage, check its weight, and abide by any package shipping instructions. By connecting robots with managers, customers can be automatically alerted if any products that aren’t available before the truck even leaves the warehouse.

3) Maintenance

Fixing a problem before it happens is the most cost-effective form of maintenance. With many aircraft engines now transmitting usage data via Wi-Fi when they are on the ground, augmented reality is assisting maintenance crews in reducing engine downtime by comparing engine data with the past history of other similar aircraft with avionics systems. These algorithms then suggest maintenance before a problem is likely to occur. For planes that spend most of their ground time at distant locations, AR can also enable more experienced maintenance teams at the airline’s hub to see what local technicians are dealing with and provide timely live support.

4) Last Mile Delivery

In logistics, the last-mile of delivery to customers is the most expensive. AR can save money by cutting the time spent on last-mile delivery nearly in half. According to a DHL report, drivers spend 40% to 60% of their day searching inside their own truck for the correct boxes to deliver next. Instead of having to remember how their truck was loaded that morning, augmented reality is used to identify, tag, sequence, and locate every parcel. Combined with artificial intelligence, AR glasses can also navigate the driver to the proper door or building gate for delivery. These systems will record each and every delivery so that new drivers will benefit from past driver experiences. In the near future, every driver will be given a graphic overlay of each building they encounter.

5) Procurement

The distributed ledger capability of blockchain is being combined with augmented reality to bring transparency and traceability to procurement. The entire supply chain falls apart when customers can’t be assured of a product’s origin or authenticity. Each year, billions of dollars’ worth of counterfeit pharmaceuticals are distributed to patients, and tens of thousands are dying. Using AR to identify and track each shipment from manufacturer to end user is a way to help solve this deadly problem. Recording each transfer of ownership on a blockchain can also assist in tracing the origin of fish or the source of harvested crops.

Big data drives the decision making behind the world’s distribution of products throughout the supply chain. Augmented reality is now poised to exponentially increase the speed at which data can be analyzed and acted on. The insights augmented reality bring to the supply chain can be used to power the next generation of the supply chain, which will feature autonomous vehicles and delivery drones.

How 3D Printing Impacts Logistics and Supply Chains- by Abhilasha Satpathy, DCMME Center Graduate Student Assistant

In recent years, 3D printing has brought manufacturing capabilities to several remote, hard-to-access areas across the globe. DHL, for instance, tells us that the U.S. Navy 3D prints drones on-demand on board its oceangoing vessels. NASA, meanwhile, is working to develop a 3D printer for the International Space Station. Shell is also experimenting with this remote manufacturing method on offshore oil platforms.

Pay-for-use or nonprofit fabrication shops are becoming more popular as well, offering public access to 3D printing tools, and some websites have begun aggregating 3D printing designs, allowing customers to compare and select printing services that work for their specific needs.These initiatives are disrupting the traditional manufacturing supply chain in several ways. In researching warehouse stocking practices in Amsterdam, DiManEx found that approximately 80% of stored products were sold only twice yearly, which led to write-offs, scrapping, and wasted materials. With on-demand, on-site printing, companies can move away from having to store excess spare parts and can instead deliver parts quickly and efficiently, whenever they’re required. Mercedes-Benz Trucks, for instance, allows customers to 3D print more than 30 cargo truck spare parts.

As 3D printing becomes more and more prevalent, expect to see increased supplier consolidation as well. For instance, logistics providers may offer added value by being the ones to process, print, and deliver 3D parts quickly and cheaply. In this way, the typical months-long process of designing, sourcing, and producing component parts can be cut down drastically. In the future, 3D printing warehouses may also take on the responsibility of material sourcing in addition to 3D end-to-end design, production, and delivery. As an example, consider Amazon’s bet on this technology: The company has patented a truck fitted with 3D printers that would allow for sophisticated mobile manufacturing capabilities. Increased responsiveness is also likely, as 3D printers allow for smaller batch sizes, which can positively impact quality control and open the door for expedited product development.

Finally, this kind of technological innovation is likely to bring about advanced customization options, as users will be able to select various aspects of the design, material, shape, size, packaging, and so on. And in gaining the power to make and deliver their own 3D-printed products, customers will no longer be limited to what suppliers themselves design and produce.

Disruptive Innovations and their applications in Supply Chain Management – by Abhilasha Satpathy, DCMME Center Graduate Student Assistant

Procurement and supply chain are at the cusp of a disruption with AI, IoT and blockchain technology. A digital transformation is ensuing with the promise of greater efficiency in business processes, operations, transparency and security.

Spend analysis

Spend analysis used in strategic sourcing, needs a shift from the traditional descriptive analytics model to more predictive and prescriptive analytics. Organizations can develop tools to enhance their spend analysis with public domain data — from social media, weather data, demographics, suppliers, competition and logistics to name a few — to help uncover insights that can save money and improve supply chain.

 

Supplier lifecycle management

The traditional supplier lifecycle management platform, when augmented by big data from the public domain, can offer meaningful information on suppliers and supply chain risks. An IoT solution can be employed to track the quality of the product at various stages of the supply chain thus improving the efficiency in the process and providing the metrics for supplier evaluation.

 

Strategic sourcing

Supplier bids are collected using online sourcing events, but a large part of the sourcing evaluation and award process is manual in nature. Using blockchain for through all steps of the process — proposals, quotes and bids — or auction, can offer greater efficiency and transparency.

 

Contract management

A blockchain platform and its smart contract framework coupled with IoT and AI, can help facilitate greater efficiency in compliance and obligation management. AI can help develop smart wizards to build contracts based on responses to specific questions and can further be enabled for pattern recognition to identify changes to standard clauses or introduction of non-standard clauses.

Order management

The traditional order management system is internal to any organization and facilitates the fulfillment process. Blockchain platform powered with AI and IoT can drive greater efficiency in orchestrating and streamlining purchase orders, shipment details, trade documents, goods receipts, quality assurance documents, returns and accounting.

Logistics

The logistics industry is an early adopter of AI, IoT and Blockchain, and is already reaping great business benefits. IoT in the logistics ecosystem can provide great insights on inventory management, shelf life, storage temperature, delivery routes, real-time tracking of freight and more

Sharing Economy in the Manufacturing Sector

According to the article (‘Can product manufacturers benefit from the sharing economy?’ <!–

by Hannah Furlong)  consumers buy less when they are provided option of sharing.

Manufacturers can benefit if they strategically design pricing and increase quality to meet customers’ needs. Research found that sharing of products that have low marginal costs can result in decreasing revenue for companies who manufacture those products since number of customers will be reduced.

For high cost products, manufacturers can charge higher prices because increased perceived value due to sharing economy business model. Manufacturers can make more efficient and durable goods to capture these opportunities.

Can product manufacturers effectively realize this opportunity? What manufacturers should prepare for these changes? What industries can be the most benefited?

Sharing Economy in the Payment Industry

Sharing Economy in the Payment Industry  

According to the article (The sharing economy is doing amazing things for mobile payments, written by ), Business based on sharing economy is conducted by peer to peer payment through mobile payment technology.

Many of sharing economy business models depend on customers being able to make mobile payments. PwC projected that the sharing economy will grow from US$15 billion in 2013 to US$335-billion in 2025 which means high potential to grow.

Does the payment industry will grow as sharing economy grow? How the payment industry should prepare for this change given the rapid growth in the technology? How customers are adopting for these changes?
