At the beginning of Terminator 2, Sarah Connor has a surreal moment when she realizes she must trust her previous nemesis, played by Schwarzenegger, to protect her son from a newer-version Terminator sent back by Skynet to kill her child.
The audience already knows Schwarzenegger’s model 101 Terminator android is outmatched. The newer T-1000 prototype is made from a ‘mimetic polyalloy,’ a liquid metal that can change shape at will. As incredible as Schwarzenegger’s Terminator might be, the audience realizes this new machine is far superior, and that Sarah and John are doomed.
Spoiler: The audience is wrong.
3D and 4D printing have a similar relationship as the two Terminators have with each other: they both offer incredible improvements over today’s standard technology, and one is a more futuristic prototype based upon the technology of the first. And while 4D printing literally has the ability to change shape as needed (read more about that below), both technologies can have a surprising effect on your supply chain. Like the original Terminator, 3D printing has powerful assets of its own to offer.
The Advantages of 3D Printing
3D printing, otherwise known as additive manufacturing, has a forecasted annual growth of 24% through 2024. It is now used for everything from sneakers and beer brewing parts to aerospace applications. More and more industries are embracing the technology as a powerful complement to traditional manufacturing. Some reasons for this impressive growth include:
● Improved process flexibility. 3D printing shortens lead times when changing over production from one product to the next. Manufacturing time for each product is also typically shorter, which means faster response to customer demand.
● Distributed manufacturing. Local builds are possible through on-demand files sent securely to local 3D printing facilities. This option may reduce logistics and transportation time, as well as associated costs.
● Lowered labor costs. Additive manufacturing typically uses fewer parts and assembly pieces than traditional methods. This allows a reduction in overall staffing costs.
● Less waste. Since 3D printing adds material layer by layer as needed, in many cases it will reduce the amount of raw material used as compared to that used in subtractive manufacturing methods.
These advantages will smooth out any kinks in your current supply chain, offering a balance of growth, performance, and innovation while driving revenue with minimal risk.
What You Should Know about 4D Printing
4D Printing is still moving through early-stage research and development, but you will likely be hearing more about it in the coming decade. 4D is considered an extended step beyond 3D printing using the same kind of additive manufacturing processes, but with materials designed to react to specific external stimuli. These materials already have a history of use in things like smart clothing and drug delivery systems, so the technology itself isn’t new, just how it’s being applied in this kind of manufacturing.
So how is 4D different? Researchers have mapped and learned how to harness the responses of certain materials, such as the swelling and stiffness properties of a composite hydrogel material made of cellulose fibrils, which can be ‘programmed’ to react in a specific way to changes in temperature, pressure, or waterflow. Imagine water pipes that can self-heal, valves that can self-seal, or pipes that will change their diameter according to environmental changes happening around them.
Other materials can also be “programmed” to be responsive to light, heat, or electrical response. As research moves forward on 4D applications, this may lead to structures that can be printed and shipped flat to be ‘restructured’ on-site with the application of the proper stimuli, rather like Marvin the Martian’s “10,000 Instant Martians (just add water)” army. This could also lead to parts that have a known end-of-life key-code that will break them down for a simple removal and recycling option.
The primary benefit of 4D printing will be its ability to create adaptive and customized products for the entire product life cycle, not only during the product’s maturity stage, but from introduction through decline.

Hello. I intended to take a moment to express my enjoy discovering your post. This piece was a delight to read as well as you supplied a great deal of fantastic information. Considering I have actually been investigating this subject myself, I can not send sufficient “say thanks to yous” your means.
Pretty nice post. I simply stumbled upon your blog and
wished to say that I have really enjoyed browsing your blog
posts. In any case I will be subscribing to your feed and I’m hoping
you write again soon!
Usually I don’t learn article on blogs, but I wish to say that this write-up very pressured
me to try and do it! Your writing style has been amazed me.
Thanks, quite great article.
I believed I was the only one who wanted to know regarding this subject. It is comforting to know that others are interested. I really hope that you will remain to discuss it so that myself and also others can find our answers easily.
An intriguing discussion is worth comment. I believe that you should publish more on this subject, it may not be a taboo subject but generally folks don’t talk about such issues.
To the next! All the best!!
