Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Quality assurance and production are the same thing in 3D printing. | Quality assurance and production are two distinct roles in 3D printing. Production involves creating the physical object, while quality assurance ensures that the final product meets certain standards of quality. |
| Quality assurance is not necessary for 3D printing because it’s a simple process. | Quality assurance is essential for ensuring that the final product meets specific requirements, such as dimensional accuracy, surface finish, and mechanical properties. Without proper quality control measures, there may be defects or inconsistencies in the printed parts that could compromise their functionality or safety. |
| The role of quality assurance is only to catch errors after they occur during production. | While catching errors during production is an important part of quality control, it’s equally crucial to prevent them from happening in the first place by implementing robust design guidelines and testing procedures before starting mass production runs. This proactive approach can help identify potential issues early on and minimize waste and rework costs down the line. |
| Production takes precedence over quality assurance in 3D printing since speed is critical to meet demand. | While meeting deadlines is undoubtedly important for any manufacturing process, sacrificing quality for speed can lead to costly mistakes down the road if defective products make it into customers’ hands or cause delays due to rework needs later on. |
