Common Mistakes And Misconceptions
| Mistake/Misconception |
Correct Viewpoint |
| Additive manufacturing and CNC machining are the same thing. |
While both processes involve creating parts from digital designs, they use different methods to achieve this. Additive manufacturing builds up layers of material to create a part, while CNC machining removes material from a block or sheet of material to create a part. |
| Additive manufacturing will replace CNC machining entirely. |
While additive manufacturing has many advantages over traditional machining methods, it is not always the best choice for every application. There are still many situations where CNC machining is more efficient or cost-effective than additive manufacturing. |
| There are no career opportunities in additive manufacturing yet. |
The field of additive manufacturing is rapidly growing and there are already many job opportunities available in areas such as design, engineering, materials science, and production management. As the technology continues to advance, even more career opportunities will become available in this field. |
| Only engineers can work in additive manufacturing or CNC machining careers. |
While having an engineering degree may be helpful for some positions within these fields, there are also many other roles that do not require an engineering background such as machine operators, technicians and quality control specialists among others. |
| Additive Manufacturing requires less skill compared to CNC Machining. |
Both fields require specialized skills but with different focus areas; 3D printing experts need knowledge on CAD software programs like SolidWorks while machinists must have expertise on programming languages like G-code which makes them equally important professions requiring high levels of technical know-how. |
