Generally, 3D printing technologies such as hot melt stacking and photopolymerization are used to "additively manufacture" sample prototypes, offering a wide variety of choices in 3D printing filaments and photosensitive resins . In contrast, "subtractive manufacturing " using CNC milling technology involves shaping the raw material by cutting it with a cutting tool. This completely different manufacturing method and its unique characteristics are revealed below:
CNC (Computer Numerical Control) means controlling a machine tool with "computer numerical values" . It uses the precise calculations of a computer to control the machine tool to perform precision machining. CNC machine tools, CNC machine tools, CNC lathes, and CNC milling machines are all machines that use computer calculations for machining. A milling machine is like a sculptor. Commonly used materials include ABS , POM, metal, nylon plastic, wax molds, PVC plywood, hardwood, and resin. Its high precision and low error characteristics make it suitable for making various functional parts.
Depending on the shape and precision of the object, different types of cutting tools can be selected. Because the machining process involves cutting, a large amount of debris is generated. The Roland MDX50 's automatic tool changer system allows users to simply place the desired tool in the internal tool magazine before starting the operation. During the process, no manual removal or replacement is required; the machine automatically engages with the chuck to change tools, ensuring both safety and convenience!

Resin objects can be easily shaped using a milling machine. To fix the position of the object, there are fixed supports between the finished product and the raw material block, which can be removed after processing.
Using the MDX-540 desktop CNC milling machine , you can quickly process various metal materials to produce high-precision, low-error results with a smooth, non-rough matte finish. The desktop machine is sized to fit any office environment, saving on outsourcing costs and allowing you to complete your work in your own studio!
