Here are the top reasons manufacturers, engineers and designers are switching to additive manufacturing and 3D printers.
3D printing is one of the most popular methods of creating a prototype. It allows producing parts locally, which is especially important for low-volume manufacturing and end-use parts. 3D printing greatly reduces waste materials, since the printing process does not use any support structures or molds. Designers can successively iterate their designs during the development cycle and quickly make changes with 3D printing. This is an advantage over traditional manufacturing techniques where design changes may take months to implement.

3D printing is a process of making a physical object from a digital file. When you have built your 3D model, you will then need to prepare it for printing by performing any of the following: scaling, cleaning up the geometry and adding support structures where needed.
Once this is done, it's time to send your file off to print!
3D printing can make very complex parts that are impossible to manufacture using traditional processes such as machining or injection molding. Some of the things that 3D printing excels at are making small batches of prototypes and end-use parts, creating functional components in hard-to-access areas (for example, inside an engine), and producing customized components quickly.
3D printers typically create objects by fusing together layers of different materials using lasers or ultraviolet light. These layers are usually created one at a time, but some machines use multiple heads to build in multiple colors or materials simultaneously.
3D printing allows producing parts locally, which is especially important for low-volume manufacturing and end-use parts. It is often not possible to find a part in the local market or have it manufactured by a third party on demand. The 3D printer can be used to produce these parts, making them available in your factory or office immediately.
In addition, it is possible to use additive manufacturing to produce unique components that are not mass produced but still needed as part of an assembly line process. For example, you could use 3D printing technology for producing special tools for maintenance engineers working with complex machinery. In this case, the cost savings would come from being able to reduce spare stock requirements and save valuable storage space (and thus money) by using 3D printed tools instead of standard ones mounted in toolboxes or cabinets at each workstation – saving both money spent on actual tools themselves as well as personnel costs involved with maintaining them over time.
3D printing can greatly reduce waste materials, since the printing process does not use any support structures or molds. Instead of creating a mold, 3D printers can create parts that have no need for post-processing. Without having to add support structures and molds during 3D printing, you will save time and money while also reducing your carbon footprint and the amount of waste that goes into landfills or oceans.
Only one-third of products are recycled worldwide; this means that most products end up as trash in landfills or oceans where they take years to decompose and pollute our environment.

A significant advantage of 3D printing over traditional manufacturing techniques is that designers can successively iterate their designs during the development cycle and quickly make changes with 3D printing. This is an advantage over traditional manufacturing techniques where design changes may take months to implement.
With additive manufacturing, designers can make small adjustments to their designs without having to wait for new parts or molds, which would be necessary in traditional manufacturing processes.
3D printing is a promising technology which has several advantages over other techniques.
It allows you to create products that were previously out of reach for most people.
You can make almost any part using this technique, which is not possible with traditional manufacturing methods.
3D printers are suitable for many different types of materials, including metal and plastic. This allows them to be used in all kinds of industries from aerospace to automotive, construction and consumer goods manufacturing as well as healthcare.
3D printing also has its drawbacks; it is still too expensive for mass production purposes or small-batch runs, so it’s not yet cost effective for all applications just yet but cost reductions are expected in future years as the technology becomes more popular.

3D printing is an exciting and promising technology that has the potential to revolutionize how we design, manufacture, and use products. The process has many benefits over traditional manufacturing techniques such as reducing waste materials, allowing for on-demand production of parts and prototypes, making complex structures easier to create, allowing local production of end-use parts and even improving product design through iterative prototyping cycles.
