Making three-dimensional solid items or products out of digital files or using numerical data is known as additive manufacturing, sometimes known as 3D printing. We’ll also compete with the subtractive manufacture of metals like copper, gold, silver, etc., which is an industry that uses 3D printing to carve out or excavate objects. Additionally, with the purchase of a milling machine, it will mostly be utilised by the plastics business.
Every manufacturing sector has created a sizable number of intricate shapes, and 3D printing will assist build them with less material than conventional production processes. Compared to the well-known subtractive machines known as CNC machining or moldable machines known as injection moulding, it is a different method of generating the parts; in these technologies, 3D printing is crucial to manufacturers.
Since its founding, some thirty years ago, additive manufacturing has been expanding steadily. Increased employment in additive manufacturing has resulted from this increase in several different sectors, including the automotive, aerospace, medical, and consumer products industries. Both in the engineering community and the general media, 3D printing has received a lot of coverage.
It’s fair to argue that some of it is hype, but other parts are really helpful, and some of it might even be harmful! We adopt a strictly industry-based strategy and viewpoint when discussing how 3D printing may be used to improve products and generate revenue, in contrast to much of the media frenzy around this technology.
Here, we’ll look more closely at 3D printing to better understand how it may help small manufacturers, CAD designers, and engineering consultants with product creation.
What is 3D printing?
Three-dimensional solid things are formed by the additive manufacturing technique, often known as 3D printing, by layering materials on top of a digital model. To function properly, software, hardware, and materials are necessary for all 3D printing operations.
Businesses can swiftly develop functional prototypes with 3D printing, while individuals can use them to create a variety of household accessories. Even though plastic is still the most popular printing material, additive manufacturing, which employs materials like metal, cement, and even glass, allows for the manufacture of everything from microscopic screws to engine components to complete homes, and it’s only just getting started.
How Does 3D Printing Work?
Making a 3D model on your computer is the first step in the process. This digital design could be a CAD (computer-aided design) file, for example. A 3D model is produced using 3D modelling software or data from a 3D scanner. You can make an electronic replica of an object with a 3D scanner.
Applications of 3D Printing
Rapid manufacturing and prototyping, as well as the automotive, aerospace, aviation, building, and product design industries, as well as the fields of medicine, food, fashion, and movie props, are just a few examples of applications.
Other applications of 3D printing in science and technology include the reconstruction of fossils in palaeontology, the replication of historic artefacts in archaeology, the reconstruction of bones and body parts in forensic pathology, and the reconstruction of severely damaged evidence recovered from crime scenes.
3D Printing Benefits for Small Manufacturing Businesses and Engineers
Traditionally, models of potential products, assemblies, or components were made out of foam, wood, and clay. The issue with this is that it necessitates specialised knowledge, can be fairly expensive, and is rarely finished quickly. This meant that modelling was more of a goal than a reality for many small enterprises. As a result, designs would be transferred immediately from CAD or technical drawings to production. Unfortunately, this frequently led to errors and flaws that needed expensive and time-consuming correction.
The benefits of additive manufacturing and 3D printing are best shown in this situation. Before investing in expensive production tooling and manufacturing, it enables engineers to optimise and validate ideas. In addition, it is readily available, reasonably priced, and has a lot of support. In addition to being rapid and requiring only basic knowledge and skills, these factors are also significant. Just a 3D CAD model will do to get things started. Small manufacturers, therefore, stand to gain a lot from this.
3D Printing Market Trends
From 2013 to 2018, the 3D printing market expanded quickly. By the end of 2018, the 3D printing market is anticipated to generate 12 billion in annual revenues. Future living, employment, and leisure patterns will shift as 3D printing technology gradually penetrates nearly all significant industries.
