All over the world, people are discovering that 3D printing can take them to new heights.  With the help of 3D printing, an individual can design their custom products. Providing capability, customizability, and accessibility of affordable production, 3D printing is rapidly changing the dynamics of how we make things. You must always think about the best tools and processes to finish your design when you want to develop a product prototype. The three main ways to design prototypes are
- subtractive manufacturing (CNC machine parts).
- injection molding (designed to pre-produce prototypes).
- 3D printing.
It is pivotal to understanding the differences between these three types of product development methods to pick the right technology for your project and determine if 3D printing is the best option.
Difference between Subtractive Manufacturing, Injection Molding, and 3D Printing
Subtractive manufacturing is a product development process used to create 3D objects by continuously cutting material from a solid block of material such as metal. This can be carried out manually or with a CNC machine. Injection molding, on the other hand, is a manufacturing process for producing products in large volumes. It can be used to do initial product prototypes but is mostly used in mass-production processes where one production part can be created thousands if not millions of times in succession.
3D printing is also known as additive manufacturing, which refers to the process of producing 3-dimensional solid objects from a computer file. Printing happens in an additive process where a solid object is developed through the successive layering of material. There is a wide range of materials to choose from including plastic and metal. The procedure starts with the creation of a 3D digital file such as Computer-Aided Design.
What is 3D Printing?
3D printing can be defined as a process of creating a three-dimensional solid object from a digital file. An object in an additive process is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes in the 1990s and a more appropriate term for it at the time was rapid prototyping. 3D printing is different from subtractive manufacturing which is cutting out/hollowing out a piece of metal or plastic with for instance a milling machine.
Benefits of 3D printing technology:-
3D printing has been adopted by many companies. The remaining company has plans to adopt the technology and replace traditional subtractive manufacturing. And that’s why recent research shows that over 70 percent of manufactures have now adopted 3D printing.3 D printing can provide many benefits both for individuals as well as for businesses. Here are five significant benefits that 3D printing provides:-
As compared to conventional manufacturing 3D printing is quicker including injection molds and subtractive production. In 3D printing faster design and prototype production is achieved means more time to iterate the prototype and find product-market fit before competitors. 3D printing production takes just hours.
Accessibility of 3D printing is more and can be used by a much wider range of people than manufacturing setups. 3D printing is almost fully automated requiring little to no additional personnel to run, supervise, and maintain the machine, making it much more accessible than other manufacturing systems by a good margin.
As traditional manufacturing methods are easy but the design is very poor, and therefore poor quality prototypes. In 3D printing, the step-by-step assembly of the object is done, which guarantees enhanced designs and eventually better quality objects.
For small production runs and applications, 3D printing is the most cost-effective manufacturing process.
Another big advantage of 3D printing is that any given printer can create almost anything that fits within its build volume. The design of 3D printing, is fed into slicer software, needed supports added, and then printed with little or no change at all in the physical machinery or equipment.
Innovation in 3D printing:-
3Dprinting innovation has come on leaps and bounds in recent years, when we talk about 3d printing we no longer talk about just printing small scale models for the fun of it, but we are talking about producing realistic prototypes and end-use parts, for many different industries such as medical, consumer goods, manufacturing, aerospace and automotive, just to name a few.3D printing is changing lives for the better, for example, 3D printing in surgeries, aerospace parts, and dental applications.
