Technology has been advancing at an absolutely breakneck pace for the last 20 years. I still recall dialup internet tones and having to wait literal minutes for a picture to download and hopefully, nobody picked up the phone or it would all be a waste. I still remember car phones for God sake. Everything about our lives is in a constant and unending state of flux. The next revolution is just around the corner when everything about our lives will change again. Even something as seemingly simple as printing Pasadena will experience the revolution as the tide comes. There are a few things we don’t tend to think about when we envision the changing tides of technological advancement. The way we eat, printing, and shoes just to name a few innocuous ones. Even those are subject to the changing landscape. Printing, for instance, is edging ever closer to Star Trek-style replicators. Today with 3D additive printing we aren’t far away, just slower than we like. How exactly does 3D printing work? There are a couple of ways that 3D printing works in the current iterations. Excluding the advancements being made for organic printing for the time being. Although that is getting wild to see where we’re printing literal organs and they’re close to working so soon as we’re able to replicate the blood vessel structure for the smaller vessels inside the tissue. Really interesting stuff if you want to go read about that (once we’re done of course). The types of printing that we see are additive printing and subtractive printing. Additive printing works by steadily adding the material the product (usually plastic) to the structure in the right way in order to create the final product. Subtractive works by steadily removing pieces of whatever material you’re working with until the desired form has been manufactured. That’s the incredibly basic one-paragraph explanation of the process. It starts with either a computer-aided design (CAD) or a scan of an already existing 3D object. From there the printer works through the exact way to create the object. It does this by steadily layering droplets of the (for our work it’ll be plastic) plastic in layers. It puts each of the thin layers one on top of the other. Each one either adding to the height, width, and structure of the piece. There are many many ways that this can be achieved but they almost all work in a roughly similar fashion. Droplets of the material are added bit by bit until eventually, you have a completed 3D design, similar to the way an inkjet printer works. 3D printing isn’t just reserved for large factories anymore. It’s attainable even in the consumer space and it’s not overly expensive either. Granted every type of printer is different but they usually cost in the real of $200 up to $500 for smaller printers. The price can go much higher for industrial-grade 3D printers. Currently, 3D printers are mostly used in universities and in workplaces that require them. They aren’t common enough to be featured in printing shops you’d find if you went searching for printing Pasadena . Eventually, they will grasp it as the need increases. It’s all part of the changing evolution.
