In the world of manufacturing, two cutting-edge technologies have emerged as game-changers: Metal 3D printing and CNC machining. Both processes offer unique advantages and have revolutionized the way we design and produce metal parts. In this article, we will delve into the characteristics, benefits, cost considerations, and design factors of these two technologies to assist you in determining which one is better aligned with your specific requirements.
Reduced waste, production efficiency and functional gain driven by greater design freedom and flexibility. An increasingly familiar summary of the key benefits afforded by metal 3D printing. Meanwhile, high-volume repeatability, precision surface finishing, particularly in relation to tight tolerances, remain characteristics more closely associated with CNC machining.
What is Metal 3D printing and its advantages?
Metal 3D printers are uniquely suited to fabricate complex parts. From the ultra-complex to process-optimized, they can print everything from generatively designed structures to custom cooling channels. For these parts, 3D printed metal strength performs well in demanding applications.
Metal 3D printing is not only an innovation of business model, but also brings huge benefits to the manufacturing industry. In the aerospace, automotive and energy industries, metal 3D printing technology is playing a more important role. According to the statistics of Xtmadeparts, in the future, industrial-grade metal 3D printing is expected to be considered as the main technology choice.

What is CNC machining and its advantages?
CNC machining, or computer numerical control machining, is a manufacturing process that utilizes computer-aided machines to cut metal or other materials into intricate patterns and shapes. It offers many unique benefits that make it a valuable technology for a wide range of industries.
CNC machining is an economical, efficient, and precise process of manufacturing parts and products. CNC machining also uses fewer raw materials in comparison to conventional machining. Focusing your shop around CNC technology will drastically reduce errors, production expenditures, and product costs.
Among the outstanding CNC machining benefits for machinists is that it allows them to re-shape and redesign existing parts without having to start from scratch. When they do create a part from scratch, they do so through CAD (computer-aided design) software which enables them to make very intricate designs with minimal wasted material. This method of machining can reduce waste and save money thanks to the computer’s capabilities and automation, instead of relying on human operators. Additional valuable differences make themselves plain depending on the application.
- CNC Machining Generates Minimal to No Waste
- CNC Machining Is More Accurate and Has No Defects
- CNC Machining Offers More Rapid and Effective Production
- CNC Machining Makes Assembly Faster
- CNC Machining Separates Machines From People And Reduces the Risk That Would Otherwise Arise
- CNC Machining Uses Little Energy
- CNC Machining Can Reduce Production Costs
3D Printing Definition and Comparison to CNC Machining
The advantages of 3D printing compared to CNC machining are:
- 3D printing delivers parts quickly, whereas CNC machining requires individual setup and (generally) manual programming plus supervision.
- 3D printing is generally a lower-cost method than other ways of making complex net shapes. It requires minimal setup and operational intervention. It’s common for CNC components to be 10x the price of 3D printed parts.
- 3D printers that are office friendly and require only modest skills in setup and maintenance are increasingly common. They are also increasingly capable of satisfying the majority of needs. CNC remains a heavy-engineering and highly skilled process requiring constantly refreshed skills in the operators.
The advantages of CNC machining compared to 3D printing are:
- CNC machining uses engineering materials and delivers the full properties of the materials, undisrupted by the process. 3D printing, on the other hand, can sometimes achieve this, but generally uses weaker material approximations.
- CNC parts are more precise, as machine tolerances can be held closer than 3D print tolerances.
Cost Comparison: CNC machining will carry all of the programming and setup costs and it will be expensive in comparison to 3D printing – often five to ten times the price. However, whenever a series of prototypes with small adjustments are required, the modified CNC-cut parts will carry a much lower setup cost, whereas a second 3D printed part will cost the same as the first.
Speed comparison: Preparation for the printing of a 3D component requires little time to set up before a print can commence. Although printing is slow by some measures, most prints will likely complete within a few hours and be ready to use. CNC machining, on the other hand, requires skilled preparation of programming for cutter selection and cutter path. It often requires custom or modified jigs to retain the part during processing (including possible repositioning of the part). This can consume considerable time before the first cut. Cutting, however, is generally fast, and complex parts can generally be completed in an hour or less of actual machining. Total time for preparation and machining can run into a day or more, depending on complexity.
Volume comparison: When the extensive setup effort can be shared over multiple parts, CNC machining can produce more cost-effective parts compared to 3D printing. 3D printing has fewer volume advantages, as each part takes the same material and machine costs, irrespective of volume.
Materials comparison: In material selection (and successful delivery of material properties), CNC offers better options. Essentially the material choice is open to all engineering materials, up to and including spark-erosion CNC machining of pre-hardened tool steels. CNC-machined parts deliver the native properties of the billet material, largely undisturbed by processing characteristics.
3D printed parts are restricted to those supported by particular processes. The construction methods of the particular 3D print technology impose severe restrictions on the delivery of properties. Prints are often weakened by anisotropic “grain” in the construction method, porosity, poor layer bonding, and the substitution of printable but non-engineering materials.
