Introduction
A digital file can be used to create three-dimensional solid objects using additive manufacturing, also known as 3D printing. It is a technology that has developed significantly in recent years and will continue to develop as it improves what it offers.
The phrase "3D printing" encompasses a variety of methods and technologies that provide a comprehensive range of capabilities for the manufacturing of parts and products from a variety of materials. All of the techniques and technologies have in common the manner in which production is accomplished layer by layer in an additive process, as opposed to traditional methods of production employing subtractive procedures or molding/casting processes. Uses of 3D printing are appearing nearly daily, and as this technology continues to permeate more broadly and profoundly into the industrial, maker, and consumer sectors, this trend will only continue. The majority of credible experts on this technology sector concur that the true potential of 3D printing is only now beginning to be realized. We provide you with the most recent perspectives, process breakthroughs, and applications as they emerge in this exciting sector. The purpose of this book is to provide a reliable introduction to 3D printing in terms of what it is (technologies, processes, and materials), its application areas, advantages, and more.
Chapter 1
What is 3D Printing?
A digital file can be used to create three-dimensional solid objects using additive manufacturing, also known as 3D printing.
Utilizing additive processes, 3D printed objects are produced. In an additive process, an object is made by adding layers of material one after another until the object is made. It is possible to think of each of these layers as a thinly sliced cross-section of the object.
Subtractive manufacturing, which involves hollowing out a piece of metal or plastic using a milling machine, is the opposite of 3D printing.
With 3D printing, you can create intricate shapes with less material than with conventional manufacturing techniques.
How Does 3D Printers Operate?
A 3D model is where it all begins. One can be built entirely from scratch or downloaded from a 3D library.
3D programs
The following step is to get the printable file ready for your 3D printer. We refer to this as slicing.
From printable file to 3D printer through slicing
Slicing is the process of using software to divide a 3D model into hundreds or thousands of layers.
Your file is prepared for your 3D printer once it has been sliced. You can use USB, SD, or Wi-Fi to send the file to your printer. Your sliced file is now prepared for layer-by-layer 3D printing.
Industries of 3D printing
Critical mass for 3D printing adoption has been reached, and those who haven't included additive manufacturing in their supply chain yet are now in an ever-diminishing minority. Once solely useful for prototype and one-off manufacturing, 3D printing is now quickly evolving into a production technology.
The majority of the existing 3D printing market is driven by the industrial sector. By 2026, the global 3D printing market is expected to grow to $41 billion, according to Acumen Research and Consulting.
As it develops, 3D printing technology is expected to drastically alter virtually every major business as well as the way future generations will live, work, and play.
Illustrations of 3D printing
As 3D printing is utilized in practically every industry you can imagine, it spans a wide range of technologies and materials. It's crucial to think of it as a collection of many industries with a wide range of potential applications.
a few instances
Dental products, prosthetics, architectural scale models and maquettes, the reconstruction of evidence in forensic pathology, the replication of ancient artifacts, consumer products (footwear, furniture, design), industrial products (manufacturing tools, prototypes), fossil reconstruction, and movie props.
Fast manufacturing and prototyping
Since the late 1970s, businesses have used 3D printers to make prototypes as part of their design process. Rapid prototyping is the process of using 3D printers for these needs.
The benefits of using 3D printers for rapid prototyping.
In a nutshell, it's quick and reasonably priced. It takes days rather than weeks to go from having an idea to having a 3D model in your hands and finally a prototype. Making iterations is simpler and less expensive, and you don't require pricey molds or equipment.
Rapid manufacturing is another application for 3D printing in addition to quick prototyping. Using 3D printers for short run/small batch custom manufacturing, rapid manufacturing is a new way of manufacturing.
Automotive 3D printing has long been used by automobile makers. Automobile manufacturers print end-use components as well as spare parts, tools, jigs, and fixtures. On-demand manufacturing made possible by 3D printing has reduced inventory levels and sped up design and production.
Globally, auto enthusiasts are adopting 3D printed parts to restore vintage vehicles. One such instance involves the use of 3D-printed components by Australian engineers to revive a Delage Type-C. They had to print components that had been out of production for many years in order to do this.
Aviation is a big fan of additive manufacturing, in large part because of the promise of stronger, lighter structures that 3D printing offers. Recently, the aviation industry has experienced a ton of advances, including the emergence of printed versions of more vital components.
Generator Center Frame
The turbine center frame, which was printed by GE as part of the EU Clean Sky 2 initiative, was one of the biggest components manufactured this year.
The Advanced Additive Integrated Turbine Centre Frame (TCF) is a 1-meter-diameter part that GE and a team from the TUHH, TU Dresden, and Autodesk printed in nickel alloy 718. One of the biggest single metal parts printed for aircraft is this one.
Vast the middle of the turbine.
These kinds of components are often cast, and they have several sections. In the case of the 3D printed variant, there was only one piece needed instead of the original assembly's 150 components. The printed version gains from a 30% decrease in cost and mass as well as a lead time reduction from 9 months to just 10 weeks.
EASA-Certified Metal Parts
The first load-bearing metal component that had been authorized for use in aviation was claimed to have been developed by Lufthansa Technik and Premium AEROTEC back in June 2022.
The new A-link, which was created utilizing LPBF, outperformed the conventionally forged variant in terms of tensile strength.
In order to verify quality and repeatability for certification, a significant number of test parts were produced and put through testing at Premium AEROTEC's facilities in Varel, Germany.
Titanium A-links with print
The printing of the part resulted in a cost reduction for the component and paved the way for the use of this manufacturing technique in the future to produce metal parts of structural importance. Also, it was utilized to evaluate the procedure and show how to certify load-bearing AM parts.
Injector for hypersonic fuel
The following printed object was never meant to be mounted on an aircraft; instead, it was created to be set up in a laboratory for analyzing flow conditions at supersonic speeds.
The air traveling around the vehicle is tremendously hot and the pressure goes up dramatically when flying at Mach 5 or higher speeds. These circumstances may make the air itself chemically reactive, which affects the operation of fuel-burning vehicles.
In order to reproduce the flow conditions, researchers at Purdue built a massive burner to simulate the hot, fast, high pressure seen in hypersonic flight. Simulating flow conditions with CFD is computationally expensive (if not impossible), so to replicate the flow conditions. They essentially constructed a rocket nozzle and tested the test parts by inserting them into the exhaust plume.
Printed-on-demand fuel injectors
To generate particular turbulent flow patterns and a steady flame, the injectors they 3D-printed deliver fuel and air into the combustion chamber.
Hastelloy X, a superalloy with improved temperature resistance, was used to print the injectors. The crew quickly printed a variety of injectors, tested each one in the burner, and determined which one performed the best.
At a fraction of the cost (and risk) compared to doing it kilometers above the Earth's surface, they can now simulate hypersonic conditions for flying on Earth. This is advantageous for both spacecraft and rapid airplanes like scramjet-powered ones.
Consumer Products
There are many instances of 3D-printed consumer goods in use today.
Eyewear
By 2028, it is expected that the market for 3D printed eyeglasses would be worth $3.4 billion. The category of end-use frames is one that is rapidly expanding. Considering how simple it is to include an individual's dimensions into the finished product, 3D printing is an especially good production technique for eyewear frames.
But did you know that lenses may also be printed in 3D? When traditional glass lenses are cut from a considerably larger block of material called a blank, roughly 80% of it is wasted, they don't begin out thin and light. 80% of those figures is a lot of waste when we consider how many people wear glasses and how frequently they need to buy a new pair. Also, in order to accommodate their customers' needs for customized vision, labs must maintain substantial supplies of blanks. But 3D printing technology has now developed sufficiently to offer premium, customized ophthalmic lenses, eliminating the waste and inventory expenses of the past. The VisionEngine 3D printer prints two pairs of lenses per hour without any polishing or other post-processing using a UV-curable acrylate monomer. Also, the focal points may be fully adjusted so that a particular region of the lens can offer superior clarity at a distance while another region of the lens can offer better vision up close.
