Business is booming, fuel prices are down. So it’s time to start thinking about the next threat to the industry: 3D printing.
Advocates of 3D printing have said it can transform manufacturing. This week, a new startup company announced a new 3D printing technique it says may actually deliver on that promise.
In traditional 3D printing, the machine "prints" layers of material to create a 3D object. This takes time and leaves ripples showing where those layers were laid down. But what if you could "grow" an object out of a pool of liquid, much like the T-1000 rising from a puddle of liquid metal in the movie 'Terminator 2'?
By carefully balancing the interaction of light and oxygen, Carbon3D's new CLIP (Continuous Liquid Interface Production) technology continuously grows objects from a pool of resin. This results in smooth 3D objects that appear to magically emerge from a pool of liquid as a machine draws them upwards.
"CLIP allows businesses to produce commercial quality parts at game-changing speeds, creating a clear path to 3D manufacturing," says the company.
The CLIP process could turn out objects that are more like injection-molded items, with smooth exteriors. And it can be used to create objects from elastomers, which has applications ranging from car parts to athletic shoes.

But that's not all. A few weeks ago, researchers in Australia printed not one, but two metal jet engines. The 3D printing process used the powder form of metals, melting them and fusing them together into objects using a laser.
A Chinese company recently even printed a five-story apartment building!
In fact, a recent report from Eye For Transport found that 19% of manufacturers and retailers are already using 3D printing in their businesses.
3D printing and transportation
What does all of this mean for trucking? Andrew Schmahl, a partner in the global management consultant Strategy& (formerly Booz & Company), recently wrote an industry paper on the topic of 3D printing and the commercial transportation industry.
In short, he says, 3D printing has substantial implications for both domestic and international freight businesses. It will likely reduce the importance of some transportation lanes while possibly opening up new ones.
Schmahl offers as an example General Electric’s jet fuel nozzles. Under the traditional method, this component contained 18 separate parts made from a variety of raw materials. All of these parts had to be machined, cast, brazed, and welded before final assembly. Now, the nozzles are made from a single alloy using 3D printers with a process known as additive manufacturing, in which successive layers of the alloy are melted, shaped, cut with lasers, cooled, and then laid down on top of each other to produce the finished part. These nozzles are lighter, more durable, and more fuel-efficient than conventionally manufactured ones, GE says.
Or consider the Strati, a car designed by Phoenix-based Local Motors, which 3D printed the main structure of the car at the 2015 Detroit Auto Show, right on the floor of Cobo Hall.
The car’s body is made from thermoplastics on a 3D printer. Nonprinted parts include the motor, transmission, wheels, and steering column. You won’t see a Strati on the highway anytime soon (the maximum speed is around 40 mph, and the car doesn’t meet requirements for highway use), but it may not be long before someone in your neighborhood is tooling around in one of these electric vehicles, which will weigh about two-thirds of what a typical car weighs and will sell for between $18,000 and $30,000.
Local Motors plans to build the cars in micro-factories typically located within 100 miles of major urban centers.
"A typical car that Toyota would make is somewhere around 20,000 to 30,000 parts, that have to be moved from wherever they're made to wherever they're assembled," Schmahl told HDT. The Strati car has fewer than 50. Conceptually, what that means is 3D printing has an interesting ability to disrupt supply chains."
When Strategy& looked at nearly two dozen industry sectors, it found that as much as 41% of the air cargo business and 37% of the ocean container business is at risk because of 3D printing. Roughly a quarter of the trucking freight business is also vulnerable, due to the potential decline in goods that start as air cargo or as containers on ships and ultimately need some form of overland transport.
Looking at the 3D printability of various products and transportation cost as a percentage of the total cost of the product, Schmahl found that footwear, toys, ceramic products, electronics, and plastics have the most potential for disruption of the supply chain.
The higher the transportation cost as a percentage of total cost, he said, the more likely someone is going to look to change how and where they produce it.
"Things like food are not going to be disrupted," he said. "Pharmaceuticals, they're not going to be 3D printed because you need chemicals interacting with each other and special chemical processes to happen."
Schmahl points out, however, that 3D printing could open up opportunities in other areas. "The molecule has to get from wherever it comes out of the ground or is made in a lab to the end user," he says. "The question is, does it take the shape of a raw material like a toner which is cheap to move, or is it the finished product, which has packaging and takes up space and air" in a truck or cargo container.
These changes aren't going to happen overnight.
"3D printing has actually been around for quite a while," Schmahl says. "The best use right now is for very low runs of highly customized products, things that are really expensive to do when you have tooling you need to change out.
"The question is, where between one-off custom prototypes and the extraordinarily simple dull mass produced widget will 3D printing infiltrate? I don't know if anyone can predict that with clarity now, but I think it's safe to say more things will be 3D printed tomorrow than today."
What to do next
"It's not 'Chicken Little the sky is falling transportation as we know it is dead," Schmahl says. But it is something to start thinking about when doing long-term planning.
For instance, do you want to start diversifying your customer base so you are hauling fewer of those at-risk type of goods? Maybe you want to look at redesigning networks for more localized moves.
And think about potential for additional freight. If he were a fleet, Schmahl says, he would be asking himself, "If people are going to print in their homes and local factories, how can I get those molecules to those homes and factories?"

Complex goods will always be trucked. People just can’t afford to have complex specific processors, motherboards, unique components that haven’t been certified/tested through general quality controls, just laying around if they aren’t needed. Or afford to.
At the very least these components would have to be shipped to a person if the printer would make the easier parts/frame of an object. Then consider time spent assembling correctly. Not everyone will find it saves them money in the long run.
Maybe small parcels of simple things will decrease. These things are not a Star Trek replicator.
This, a small easy to use, personal 3D printer, is what Apple should be working on right now, not some gaudy watch that replicates my iphone and can be easily spotted by thieves.
It will not effect the trucking industry whatsoever. 3D printing is much more clever than it is a solution for things you need.
...I think I see your point...but curiously Apple has never really tackled printing in any form.
Transportation, information, food, fuel are essentials pretty much perennially...except of course in a global deflationary spiral but that's another topic.
Paging Mcluhan.
About two years ago I posted on LinkedIn my skepticism of the real need for the technology but one guy who was all-out championing it tried to embarrass and humiliate anyone who disagreed with him. Turned out that a big part of his business was to bring 3D printing technology to the masses.
3D printers do not create objects out of thin air. They need feedstock, and that has to be trucked. So it doesn’t matter if you have to truck 10,000 1 lb widgets, or 10,000 lbs of 3D printer material for 10,000 widgets.
Silly article.
A wise but cantankerous equipment operator said everything short of the air you breathe had something to do with a truck moving it.
We also need fewer blacksmiths, telegraphers, and switchboard operators than we did a century ago.
I'm fine with all of that.
Raw material transport unaffected to date, because we can’t recycle 3D printed items into new 3D printed items.
Without efficient and effective recycling of these shapes and materials on site into new items, trash disposal processes are unchanged.
A lot of material transport is unaffected, from wood paneling to wool to food.
Long distance imports of cheap knick knacks from China will drop off with time.
3D printing is a great technology that can greatly reduce design times for just about anything in manufacturing. That said, the impact to the trucking industry will be nominal at best.
3D printing can greatly reduce the number of parts.
How about putting a 3D printer in a truck, and manufacture the item while in the process of delivering the 3D item to its destination? :)
how about quality control of the 3d printed product?
how about a truck based 3d printers for repairs or on site production.
taxes too high? 3d print at some other state or city...
