Transparent Acrylic PC / PMMA Plastic Rapid Prototype High Polishing Part
In plastic CNC machining (Digital Computer Control), the part is manufactured by machining in the mass of a plastic block by digital milling machines. This rapid prototyping technology is suitable for unit production in the context of functional testing.
CNC machining of plastic prototype parts is a so-called “subtractive” method because there is removal of material. A wide selection of resins allows parts to be obtained in the “right material”, thus allowing mechanical properties close to the injection-moulded part (ABS, PC, PP, PVC, POM, PMMA, PA 6/66).
This is the most efficient and economical technology for the rapid manufacturing of fewer than ten prototypes or plastic models.

In manufacturing, computer numerical control (CNC) or simply numerical control (NC) is the automated control of machining tools (drills, boring tools, lathes) by means of a computer, in which a NC machine operates on a piece of material (metal, plastic, wood, ceramic, or composite) to transform it to precise specifications. NC machines combine a motorized maneuverable tool and often a motorized maneuverable platform, which are both controlled by a computer core, according to specific input instructions. Instructions are delivered to an NC machine in the form of graphical computer-aided design (CAD) files, which are transformed into a sequential program of machine control instructions, and then executed.
As with CNC subtractive methods, the computer-aided-design – computer-aided manufacturing CAD -CAM workflow in the traditional Rapid Prototyping process starts with the creation of geometric data, either as a 3D solid using a CAD workstation, or 2D slices using a scanning device. For Rapid prototyping this data must represent a valid geometric model; namely, one whose boundary surfaces enclose a finite volume, contain no holes exposing the interior, and do not fold back on themselves.
In other words, the object must have an "inside". The model is valid if for each point in 3D space the computer can determine uniquely whether that point lies inside, on, or outside the boundary surface of the model. CAD post-processors will approximate the application vendors' internal CAD geometric forms (e.g., B-splines) with a simplified mathematical form, which in turn is expressed in a specified data format which is a common feature in additive manufacturing: STL (stereolithography) a de facto standard for transferring solid geometric models to SFF machines. To obtain the necessary motion control trajectories to drive the actual SFF, rapid prototyping, 3D printing or additive manufacturing mechanism, the prepared geometric model is typically sliced into layers, and the slices are scanned into lines (producing a "2D drawing" used to generate trajectory as in CNC's toolpath), mimicking in reverse the layer-to-layer physical building process.
