<p>Is there a difference between 3D printing and additive manufacturing if any then explain?</p>

As worded by <a href="https://www.additivemanufacturing.media/columns/additive-manufacturing-and-3d-printing-are-two-different-things" rel="nofollow noreferrer">Peter Zelinski</a> in August 2017:</p>\n<blockquote>\n<p>To be sure, the terms overlap. They can be used in ways that make them\nsound like synonyms. But the relationship between them and the\ndifference between them is this: <strong>3D printing is the operation at the\nheart of additive manufacturing</strong>, just as “turning” or “molding” might\nbe the operation at the heart of a conventional manufacturing process.\nIn short, <strong>additive manufacturing requires and includes 3D printing,\nbut it also entails more than 3D printing, and it refers to something\nmore rigorous</strong>.</p>\n</blockquote>\n'}, {'answer_id': 7452, 'author': 'Trish', 'author_id': 8884, 'author_profile': 'https://3dprinting.stackexchange.com/users/8884', 'pm_score': 3, 'selected': False, 'text': "<p>Yes and No at the same time:</p>\n<h1>3D Printing is a subset of Additive Manufacturing</h1>\n<h3>but treated as a synonym at this time</h3>\n<p>3D printing is a process that takes some material, in a fluid state that fuses with the model to shape an object from it. The material could be plastics, ceramic paste or even metal. The fluid state could be the normal state, or just be present for the fusing process (think powder and resin based systems), or be a transitional phase (as in filament based systems).</p>\n<p>Additive manufacturing is just a slight bit bigger: at the moment most, if not all, AM processes are some sort of 3D printing. But AM could include other processes that don't fit 3D printing. For example, an automatic bricklaying machine could, under some view, be Additive Manufacturing, but it is not 3D printing in the traditional sense.</p>\n<p>So: All 3D Printing is Additive Manufacturing, but not all Additive Manufacturing is necessarily 3D Printing.</p>\n"}, {'answer_id': 7539, 'author': '42Z0GqNNz', 'author_id': 4183, 'author_profile': 'https://3dprinting.stackexchange.com/users/4183', 'pm_score': 3, 'selected': True, 'text': '<p>I see several answers to that.</p>\n\n<p>A lot of persons say <em>3d printing</em> while they really mean <em>additive manufacturing</em>.

But it is up to anyone using these words, I just think that a serious person wouldn\'t use "3d printer" given all the mismatch that it could generate. I think we should use the exact process\' name instead (like FDM for low-priced additive manufacturing polymer machines), or if you refer to the overall technology, use <em>additive manufacturing</em>.</p>\n'}]
