There are polymers like ABS, PA (Nylon), or PC that can be both CNC machined and 3D printed, so it is a common question when to use polymer CNC machining<\/a> and when to use 3D printing<\/a>. This article will walk you through the main differences between machining and printing polymers and suggests several questions you need to ask yourself to choose the right option.<\/p>\n

Two approaches: subtractive and additive manufacturing<\/h2>\n

While the end results might be similar, CNC machining and 3D printing operate in ways opposite to each other<\/a>.<\/p>\n

CNC machining (subtractive process)<\/h3>\n

CNC machining<\/a> is a subtractive manufacturing process that begins with a solid block of plastic material, cut or shaped into the desired product by excess material using a variety of sharp rotating tools or cutters.\u00a0 \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/strong><\/p>\n

3D printing (additive process)<\/h3>\n

3D printing<\/a> is additive manufacturing, which means the initial material is built layer by layer, rather than removed as in subtractive manufacturing. 3D printing creates three-dimensional objects from reading a virtual computer design and reproduces it into a real and intangible part by using material filaments or powders.<\/p>\n
