Despite the massive technological advancements that made 3D printing more accessible to the public, 3D printers are still pretty expensive. There are companies all over the world that provide 3D printing services at various price points. Nearly all forms of 3D printing require an STL file.
An STL file is a specific format of 3D model that allows 3D printers to conveniently and effectively slice up the object into the individual layers used in the actual printing. Just like regular printers use different techniques for printing, so do 3D printers.
There are many different types of 3D printing techniques, but here are some of the most common. SLA is the first 3D printing technique that was developed. It creates objects out of thin air by printing layers and layers of a particular photopolymer on top of itself. The material begins as a liquid and changes to a solid when hit by a concentrated ultraviolet light beam. DLP is similar to stereolithography in that it uses light to harden a liquid into a solid.
However, in digital light processing, the object starts as a vat of full liquid. A portion of the liquid is exposed to light, which hardens, then the build plate is lowered by a small amount. Another shot of light hardens more of the liquid, and this process repeats.
Any leftover liquid is drained, leaving behind a solid model. SLS uses a high-power laser to fuse material particles e. Using a foot long printer, New Story is able to churn out a square-foot home , complete with walls, windows and two bedrooms in just 24 hours.
Instead of the traditional organ donation process, doctors and engineers are teaming up to develop the next wave of medical technology that can create hearts, kidneys and livers from scratch.
This breakthrough technology has the ability to change the medical industry as we know it and reduce the drastically high number of patients on the organ donation waitlist in the US. Perhaps most impressively, 3D printing technology has even fast-tracked production and durability of prosthetics while reducing costs, like how GE Additive has produced over 10, hip replacements through 3D printing from through Will the future of space travel rely on 3D-printed rockets? Companies, like Relativity Space in California, think so.
The company claims that it can 3D print a working rocket in just a few days and with one hundred times fewer parts than a normal shuttle. The rocket will be custom-printed using a proprietary alloy metal that maximizes payload capacity and minimizes assembly time. The total payload capacity for this rocket reaches 1,kg about the weight of an average Rhinoceros.
Not bad for something that came out of a printer. Not only are 3D printed materials easier to manufacture quickly and at lower costs but 3D printing also provides a way to reduce the total number of parts that need to be welded together while also significantly reducing weight and increasing strength. Spare parts, tools, jigs and fixtures can all be produced on an as-needed basis while providing flexibility that would have been unimaginable to previous generations. Additionally, 3D printing provides a way for automotive enthusiasts to customize their vehicles or restore old cars with parts that are no longer in production.
Automotive repair shops can even utilize 3D printing when faced with unusual repair requests. Consumer products, without a digital or electronic build quality, such as footwear, eyewear, jewelry and more, can all be mass-produced through 3D printing. While various other products can have their body or frame manufactured through 3D printing, any item that can be produced within a mold can also be produced through 3D printing.
What Is 3D Printing? How Does It Work? The U. Is Desperate for Ventilators and N95 Masks. Can We 3D Print Them? Not exactly. Even medicines, bones, organs and skin made to treat your injuries. After all, the notion of doing your supermarket shopping on an iPad was like something out of Star Trek 20 years ago. But, like so many household technologies, the prices will come down and 3D printer capabilities will improve over time.
Like all new technologies, the industry hype is a few years ahead of the consumer reality. Join thought-provoking conversations, follow other Independent readers and see their replies.

However, 3D printing is better suited for small-scale, limited production runs or prototyping. Depending on the use, there are some other advantages of 3D printing over other production processes.
