3D printing was a mainstream technology when it first began. There were many predictions as to whether or not it would replace the work of a traditional CNC milling company. Many thought that traditional manufacturing like injection molding would become things of the past. This however has not happened, and the future predictions now state that 3D printing will not overtake traditional CNC milling in the way some thought it would. Below is a look at why.
CNC Milling Company : More than 3D Printing
One of the main reasons that 3D printing has not taken over the work of the traditional CNC milling company is that it is limited. On the surface CNC milling and 3D printing look like opposites. Milling subtracts material, whilst printing adds it. The two actually work very well together, a combination if the two technologies are widely used. They say that opposite attract, and in this case, it is easy to see how. What can be found now, more often, are hybrid machines that combine these two processes. The CNC milling process is used first, the 3D printing finishing the tasks at hand.
So, if you were limited to one of the two technologies, which should you choose? It is a difficult choice and depends on exactly what you hope to achieve. 3D printers are definitely better at finer details. CNC Milling machines on the other hand are still far more commonly used for manufacturing large parts. Although 3D printers can handle structural work, a CNC milling company will not use one for the purpose.
CNC Milling is Quicker and Better
The parts produced by 3D printing are weaker, as they rely on molecular bonds. CNC milling however uses a solid starting block, working it down into the desired shape and form. CNC milling is currently still faster than printing, although advances are being made every day. CNC machining is still more reliable, producing higher precision parts that are more durable.
One industry that has been using 3D printer more recently is the aerospace industry. 3D printing, combined with traditional processes, is allowing for the creation of extremely complex parts. 3D printing provides geometric flexibility, meaning that the two processes work in harmony, side by side, perfectly.
Many modern CNC companies are indeed combining the two methods, the best of both worlds being used to produce the very best parts. There are advantages and disadvantages of both technologies and it can be a hard choice to make when you have to opt for one or the other. If you require precision parts, instead of investing in a milling machine, source your parts from a company that uses the most up-to-date hybrid technology.
With the strength and durability of CNC milling and the flexibility of 3D working perfectly alongside each other, there is no need for compromise.
