What Is 3D Printing?
Summary
For example, Pankl Racing Systems replaced machined jigs and fixtures with printed prototypes that saved them over $150,000 in production costs. This can be done using computer-aided design (CAD) programs or 3D scanners, and it produces a mathematical representation of the object’s three-dimensional surface that the printer can use as a blueprint. Conversely, 3D printing enables manufacturers to create replacement parts, extending the lifespan of existing equipment and minimizing the need for new purchases. For example, the use of PLA (Polylactic acid), PETG (Polyethylene terephthalate glycol-modified) or PC-ABS (Polycarbonate-acrylonitrile butadiene styrene) for 3D printing can significantly reduce the need for virgin plastic and metals in the production process. Furthermore, the printing of multicolour items – with strategies such as color palette planning, layer optimization and leveraging gradient features – can help minimize the need for frequent filament changes, further decreasing waste.
