Once these factors are known, a strong foundation can be built for a profitable 3D printing business. If this is one of your first print jobs, the easiest option is to use someone else’s work. Sites like Thingiverse, Yeggi, STL Finder, and GrabCAD provide millions of free digital designs for a variety of objects including ice scrapers, side tables, and even working watches. Many files allow you to customize a design to the measurement, resolution, or weight you need. For this reason, it’s important to engage with an experienced 3D design and fabrication team early in your project’s lifecycle.
In general, parts that are oriented parallel to the build platform will print faster than those that are oriented perpendicular to the platform. This is because the printer head can move more quickly when it is traveling in a straight line. In addition, parts that are oriented parallel to the build platform are less likely to warp or deform during printing. As a result, parallel orientation is often the best choice for large or complex parts. The slicer will have a hard time keeping up with the movements of the print head, resulting in missed steps and a less precise print.
3D printing enables manufacturers to cost-effectively produce small quantities of spare parts in ways traditional manufacturing methods cannot. Companies can decrease warehousing and manufacturing costs, shorten lead times, reduce risk, and stay agile by 3D printing spare parts. Variances between machines and materials can significantly affect the outcome of a project. Many of the factors that influence not only how fast your project can be produced but also its overall strength and quality are determined at the digital design stage.

An industrial fused deposition modeling (FDM) printer that uses filament additives, will build at an average rate of 100 mm per hour, but may be adjusted to produce up to 500 mm per hour.
Who invented 3D printing?
Compared to 3D printed plastic parts, those produced through injection molding tend to exhibit higher strength and better mechanical properties. This difference is primarily due to the continuous nature of the material in injection-molded parts, which minimizes the presence of layer lines and weak points.
Sea, Land, and Sky: How 3D Printing Impacts Transport
This forces operations and logistics teams to balance the number of parts on hand with the cost of storing them. 3D printing probably won’t replace many of the usual assembly-line methods for building standard products. Boeing has already used 3D printing to make more than 22,000 parts used on civilian and military aircraft flying today. Although less common than comparable technologies, the 3D printing process of material jetting is highly accurate since it does not require the application of heat, which causes deformation like warping. Photopolymerization printing technologies like SLA and DLP cure photosensitive resins using a light source such as a laser or a projector.
3D printing (also called additive manufacturing when done in an industrial setting) has been steadily increasing in popularity over the past ten years. The 3D printing industry was valued at $13.7 billion in 2020, according to a recent Mordor Intelligence report, and it’s projected to reach $63.46 by 2026. The skills that 3D printing teaches include prototyping and iteration, design and modeling, problem-solving, attention to detail, as well as an understanding of material science. A well-balanced mix of properties has seen PETG grow to become one of the most widely used 3D printing materials. It could easily be classed as an ‘engineering material’, but it’s also a good option for beginners thanks to good printability.
Metal powder fusion processes like SLM use a laser to melt or sinter metal powder particles. The technology is accurate, and there is no consumer-level version of it. However, metal additive manufacturing typically requires extensive post-processing. Selective laser sintering is a 3D printing technology that uses a laser to sinter particles of powder, typically nylon. SLS printers are accurate, although their main selling point is their ability to fabricate complex geometries, since they do not need to print support structures. As the layers of the print build up, the printer can bind together different types of material to create a more solid structure.
An ultraviolet laser beam is directed, with a mirror, across the surface of the resin, converting it to a solid on contact. Powdered material such as ceramic or polymer is loaded into a container. A nozzle precisely applies a small amount of an adhesive binder in the shape of that particular layer before it is covered with powder and the process repeated. If you have ever made sandcastles at the beach, you would have noticed that mixing sand with water forms a stronger structure. In a simplified way, this is the principle behind 3D printers that use binder jetting. Using an electrically charged deflecting plate and an electromagnetic field, a stream of drops can be precisely positioned on a platform. The next layer is deposited above and the process repeats until the final model is completed.
The techniques used here are highly varied depending on the scanning modality, anatomical subject, and image quality. Traditional approaches require significant time and expertise but programs with advanced segmentation capability such as Simpleware software can expedite this process. There are many applications for 3D printing in the medical industry, and each year doctors and scientists come up with new and creative ways to use this fast-growing technology. The speed and versatility of 3D printing makes it perfect for developing customized prosthetics and implants and patient-specific replicas of bones, organs and blood vessels. It is also used for 3D printing surgical tools, anatomical models, personalized medical equipment and a range of other life-saving innovations. The two main methods of 3D modelling are ‘solid modelling’ and ‘surface modelling’, and there are different CAD software packages for each approach. Solid modelling refers to the creation of virtual objects through defining and joining 3D shapes that are usually predefined and to which refined surface details are added later.
It slices CAD into layers, corrects model issues, and showcases a user preview of the final output. Its premium features are handy for enterprise heavy-use 3D printers. This solution by MatterHackers is an all-in-one printer host, slicer, and CAD software for desktops. Once the model is ready to print, MatterControl 2.0 can be used to directly monitor and control printing via a USB connection or over a Wi-Fi module. DMLS increases the temperature of the particles only up to the point of fusion, whereby they combine at a molecular level.
