CNC Machining & 3D Printing: A Mixed Approach To Precision Manufacturing
Peter Jacobs, Senior Director of Marketing at CNC Masters shares how a meaningful combination of CNC machining and 3D Printing can help manufacture even the most intricate parts and boost overall productivity.
The advancing 3D printing capabilities have made it convenient for manufacturers to use additive manufacturing to develop parts from a wide variety of materials. These materials include polymers such as ABS, PLA, TPE, and carbon fibre composites, polycarbonates, and nylon.
Alongside 3D printing, precision CNC machining also enjoys a crucial role in the additive manufacturing process, with a new process called hybrid manufacturing quickly assuming its hold in the industry.
Combining CNC machining and 3D printing can meet all crucial design requirements and eliminate limitations in these individual domains.
Benefits of Combining Machining and 3D Printing
Here’s why the combination of CNC machining and 3D printing is relevant and the benefits that will follow:
-
Conservation of Time
The process of 3D printing a part and then having it delivered to the next section for CNC machining involves too many steps; however, this process is relatively less time-consuming relative to injection moulding.
In Injection moulding, the design and development of a specialised tool must go through every workpiece in the moulding process, making it more time-consuming.
While we can alternatively use 3D printed injection moulds to reduce production time, incorporating the potential of CNC machining can be more fruitful.
We can seamlessly tweak the digital files that end up getting 3D printed as prototypes rather than making alterations to an existing injection moulding machine tool.
-
Higher Tolerance Rate
3D printing has encountered hindrances in its progress due to the tolerances of modern 3D printers. Many end-use parts have specific tolerances and other vital requirements that are only feasible by incumbent manufacturing methods.
Unlike 3D printing, CNC machining is consistent. It offers a more refined product because its equipment does not exhibit sensitivity to heat as a 3D printer, which might warp and distort the product and result in uncertain runs of products.
Merging the two domains provides us with the perks of rapid prototyping brought to the table by 3D printers. It also enables us to dial in the tolerance from 0.1 mm to 0.3 mm as anticipated from a DMLS or SLS 3D printer to about 0.025 to 0.125 mm rendered by CNC Milling Machines.
-
Use a Bigger Workpiece
A congregation of these two domains involves 3D printing a part and then forwarding it to CNC milling to balance the final tolerances and providing it with the desired finish.
There has been excitements about merging these two technologies into one machine. This scenario could result in something that resembles the industrial-scale hybrid milling machines.
Such machines are speculated to harbour a build volume of about 40 feet in diameter and 10 feet in height. These hybrid 3D printing-milling machines can mill the surface of a new 3D print while the operation would still be underway.
With state-of-the-art CNC Benchtop Milling Machines, you can enjoy peak performance while occupying a minimum floor.

The Essential Guide To CNC Milling Machines
For those who may be a new entrant to the industry and would need a refresher, this article explains CNC Milling Machines, how they work, how they compare to CNC Lathes, and when to use such CNC machine tools. Article by Hwacheon.
Focused on milling – the process of machining using rotating tools to gradually remove material from a workpiece – CNC milling machines are a mainstay for factories around the world. These machine tools make use of a variety of cutting tools along one or more axes to remove material from a workpiece through mechanical means.
CNC milling machines are often used in a variety of manufacturing industries: from industries like aerospace, shipping, automobiles, and oil drilling/pumping and refining, to medical, FMC manufacturing, and precision engineering sectors.
Also called CNC Machining Centers, the more advanced CNC milling machines can operate along multiple-axis. These may be fitted with automatic tool changers, advanced machine coolant systems, pallet changers, and advanced software to improve the efficiency and accuracy of machining processes.
In this article, we will be looking at the many different aspects of a CNC milling machine/machining center.
What CNC Milling Machines Are
CNC milling machines are machine-operated cutting tools that are programmed and managed by computer numerical control (CNC) systems to accurately remove materials from a workpiece. The end result of the machining process is a specific part or product that is created using a computer aided design (CAD) software.
These machine tools are normally equipped with a main spindle and three-linear-axes to position or move the part to be machined. More advanced versions may have a 4th or 5th rotational axis to allow for more precise shapes of varying dimensions and sizes to be machined.
CNC milling machines normally employ a process of material cutting termed milling or machining – the milling process involves securing a piece of pre-shaped material (also known as the workpiece) to a fixture attached to a platform in the milling machine. A rapidly rotating tool (or a series of interchangeable tools) is then applied to the material to remove small chips of the material until the desired shape for the part is achieved.
Depending on the material used for the part, as well as the complexity of the machined part, varying axes, cutting head speeds, and feed rates may be applied.
Milling is normally used to machine parts that are not symmetrical from an axial perspective. These parts may have unique curvatures or surface contours, which may require a combination of drilling and tapping, grooves, slots, recesses, pockets and holes to work on them. They may also form parts of the tooling for other manufacturing processes – for example in the fabrication of 3D moulds.
Features of Advanced CNC Milling Machines
In the past, milling machines were manually operated. Operators had to use a combination of machines with different tools to machine a more complex part or product. Or they had to use various settings on one machine just to complete the job.
With the advancement of technology such as CNC and automatic tool changers (ATCs), greater efficiency, flexibility and speed can be achieved – even for more convoluted parts. The provision of digital readouts and measuring systems has also improved the accuracy of CNC machining processes.

High-quality Metal Parts for the Airbus A320 Made with Precise, User-friendly CNC Tech
Find out how Harmuth CNC-Frästechnik was able to overcome sheet-metal aircraft part machining challenges. Article by Stefan Ziegler, Beckhoff Automation.
In aircraft construction, exceptional component quality and precision are crucial, for obvious reasons. However, sheet-metal aircraft parts are often extremely large, making machining and handling problematic.
Working closely with CNC specialist Penta-Tec CNC-Automation GmbH and with milling specialist A&T Manufacturing GmbH—a company that supplies Premium Aerotec, an Airbus subsidiary, with structural components—Harmuth CNC-Frästechnik has built large-format milling machines that use PC-based control technology from Beckhoff to successfully overcome these challenges.
PC-based Control Provides Greater Flexibility for Machine Builders
Harmuth CNC-Frästechnik makes 3D milling machines and specialty systems, the advantages of which come to the fore in applications such as the fabrication of large sheet-metal parts for the Airbus A320 series of aircraft. The parts are supplied by A&T, as Managing Director Marc Bochinger explains, “Airbus, or rather Premium Aerotec, is our biggest customer. Besides supplying all their material (the sheet aluminium), we also form and machine large and complex structural components for them. What sets us apart at A&T is that we concentrate completely on the customer’s needs and come up with an optimized production and logistics solution in as short a time as possible.”
Power and Versatility of Standard Control Technology
“The big challenge at A&T is the need to constantly implement new machine functionality. A&T and Harmuth CNC-Frästechnik work together closely to optimize the machines—more than once, if necessary—to maximize their potential in production. PC-based control from Beckhoff covers all our requirements, not least because we can change the way axes are coupled in TwinCAT if we need to,” says Roman Felber, Technical Director at Penta-Tec.
In 2010, Penta-Tec found that rising functionality demands were pushing the performance of its proprietary control system to the limits. “We needed a new, flexible control system, capable of delivering the performance we needed. After some research and analysis of the controller market, PC-based control technology from Beckhoff soon stood out as the ideal solution,” Managing Director Dieter König says.
