FDM technology requires 3D printers and top-grade thermoplastics to create durable, stable parts with repeatable 3D printing technology. FDM 3D printing produces cost-effective prototypes on tight timelines. To achieve a smooth surface and blend in layer lines visible on FDM prints, solid post-processing steps are crucial. The right 3d printing post processing methods strengthen the prototype and produce a uniform behavior in FDM parts.

During injection molding and 3D printing, product geometry may deviate from the desired dimensionality. To counteract this, software modules must compensate with the automated correction of the CAD models.

More Flexibility in 3d Printing Post Processing

Accounting for CAD model correction gives designers and manufacturers more flexibility. Dimensionality correction shows the measuring points compare to the CAD model and the expected deviations for the printed product. Look for software that also takes user experience into account.

Besides the measuring points that allow for a more uniform surface, visualization options are another important factor in the CAD and rendering software components. Via point selection cylinders, the resolution correction can be checked to a high degree of accuracy. Point selection cylinders show the particle deviation but can be faded out to achieve a clearer presentation.

Lettering, ejector marks and other non-functional elements can be included or excluded in the correction in advanced software capable of 3d printing post processing. Several measurements impact the calculation of the deviant element. This enables consistent, efficient correction with few deviations in the CAD model.

Correction of All Rough Patches

With current 3d printing post processing software, corrections are made on the CAD workpiece or directly on a production piece. That means that measured deviations are mirrored from the model, achieving highly accurate rendering on the model and finished workpiece. This occurs along surfaces where the mold contacts the workpiece during injection molding.

Consequently, the only corrections needed include removing or adding material to perfect the finished workpiece. For instance, the workpiece may be too wide or too long, so the material must be removed.

Application

Many aerospace manufacturers use 3d printing post processing to correct modules that require precise cutting as well as structural uniformity. This reduces waste material and the emission of CO2 emission significantly for a win-win scenario.

3D printing has revolutionized the manufacturing of complex parts and post-processing methods continue to advance, promoting faster turnaround times and greater accuracy.
