How 3D printing can help businesses go green

3D printing has a lot of potential impacts and uses in business. Prototyping to producing intermediates and making end use 3D printed parts are just some of the application areas where 3D printing is seeing large-scale implementations at the moment. One of the touted benefits of 3D printing is its ability to let companies produce in a more environmentally friendly way. How can 3D printing help companies go green?

Using Less Material

Compared to traditional manufacturing technologies such as CNC, 3D printing often uses less material to make the final part. Rather than starting with a one-kilo block of material and then cutting most of it away, 3D printing builds up an object layer by layer. This means that less material is used in the final part and less material is wasted. Just how much material is saved by using 3D printing depends a lot on the geometry of the part and what it needs to do. Individual 3D printing technologies also would work very differently, which would influence how much material can be saved. In some cases metal 3D printing instead of casting has saved manufacturers 20% or more in raw material. In using FDM (Fused Deposition Modeling, FFF) some industrial parts can be made that overall use 40% less material or more. There are knock on effects of this as well; using less material means buying less and storing less which also saves on shipping and storage costs. Aerospace companies often look at buy to fly ratios to determine cost advantages of parts. A buy to fly ratio is how much material that needs to be purchased versus how much material is used on the final part in the aircraft. 3D printing often comes out as a very advantageous technology when compared to others in this way because so much of the used material ends up in the final part. This is just one of the reasons why the aircraft industry is so interested in the technology.

3D printing will change the way we make things and design them in 2017

Great article by Mike Scott in Forbes:

Much of the focus in the technology world currently is on artificial intelligence, machine learning and big data – and how they will affect the way we use products and how machines operate.

But developing just as quickly, although with slightly less hype, is 3D printing, or additive manufacturing (AM), which is going to have at least as big an impact on how we make things as AI et al. The process creates products by depositing layers of material, generally ground metal or plastic, to a template, lasering that material into place and repeating the process to build the required product – anything from replacement hips to jet engine parts.

Siemens says the technology is a “game-changer,” with benefits including a 30% cut in greenhouse gas emissions, a 63% reduction in resource use and a shrinking of the time it takes to bring products to market by 75%

3D printing our way to a greener world

3D printers are the most powerful machines ever invented because they can make finished products—with all their parts—fully assembled. They may also be the greenest machines ever built.

Green 3D PrintingDriven by a digital blueprint, these printers build layer upon layer of fused ceramics, glass, sand, plastic, metal, or other materials. In contrast, traditional manufacturing depends on assembly lines, lots of low-cost labour and mass production. Today, much of that manufacturing takes place in far-off lands, and products must be shipped in long and complex supply chains that extend around the world. All of this has a large energy footprint.

3D printing (also known as additive manufacturing) eliminates assembly lines because a single machine can make an entire part or product, and one worker can run an entire room full of 3D printers. 3D printing allows parts to be made near the point of need. Regional manufacturing, distributed all over the world, shortens supply chains and reduces shipping and warehousing.

In addition, it is no more energy-expensive, per part, to 3D print one part vs. a million parts, to customize every part instead of making them all the same, and to make highly complex parts. Using traditional methods, making complex, one-off, and customized parts is an energy hog.

Can 3D printing spark a green revolution in consumer products?

With 3D printers becoming increasingly accessible, less expensive, and able to create objects out of a range of materials, the additive manufacturing industry is poised to change the way we think about the goods we produce. And with this new technology comes questions about the implications—how will it affect people, the environment?

John Hornick, partner and litigator with the Finnegan IP law firm and author of 3D Printing Will Rock the World, believes that 3D printing will “herald a green industrial revolution.” TechRepublic talked to Hornick to learn four reasons why.
