3D printing is a method of creating three-dimensional products from a digital 3D model. It employs the use of an additive process rather than subtractive manufacturing which involves taking away layers of material to create an object.
In 3D printing, The material is added layer by layer to come up with an object that has specified dimensions and looks exactly like the digital model.
3D printing has been around for several decades, but it was only recently that the technology became widely available and affordable. The technology has huge potential with the ability to revolutionalise how products are designed and produced.
What are the advantages of 3D printing in manufacturing?
-
Cost-effective
The cost of 3D printing is much cheaper than conventional manufacturing methods. Manufacturers don’t need to invest in expensive machinery or hire skilled labour. They only need to purchase 3D printers and some raw materials.
-
Versatile and customisable
Manufacturers can use 3D printing technology to create any products they want. It allows for the manufacturing of a wide range of items including simple toys and complex machines. The technology also permits the fabrication of objects with complex geometrics that would otherwise be impossible to create.
Because this technology is versatile, manufacturers can customise it to suit their customers’ needs. They can print out unique designs and colours to meet their requirements.
-
Timely
3D printing is faster than most traditional manufacturing processes. Unlike conventional manufacturing processes, products don’t need to wait until the end of production.
-
Eco-friendly
The technology uses less material and produces fewer emissions compared to traditional manufacturing techniques.
Disadvantages in manufacturing
Even though 3D printing is a revolutionary technology in the manufacturing industry, it has its fair share of disadvantages. As much as it can be faster and more accurate than some traditional manufacturing processes, it is not fit for mass production.
Another disadvantage of this technology is that only a few materials can be used in the process. Plastic is the most widely used material since it can easily be melted and layered to create objects. The materials that can be used for this process might not provide the right properties for certain products.
Finally, since anybody can have access to 3D printers, criminals can use them to produce dangerous weapons such as guns. Some people can also take advantage of the technology and produce counterfeit products.
