Intelligent 2D nesting tool

It is very difficult or even impossible for an operator to find an optimal part placement solution manually when placing a large number of parts models. So, we developed this 2D nesting function in Voxeldance software.

Additive manufacturing (AM)is poised to bring about a revolution in the way products are designed, manufactured, and distributed to end users. Due to the layer-based processing characteristic, significant savings in cost and time can be achieved in AM by manufacturing multiple parts in a single setup to achieve efficient machine volume utilization. Intuitively, to improve the machine utilization, more parts should be placed as compactly as possible to harness the build volume so as to reduce the total build time and cost for per machine run. However, doing the part placement manually in a graphic environment is time-consuming, and it becomes more complicated when placing a batch of parts with a large quantity and very complex geometries. Furthermore, it is very difficult or even impossible for an operator to find an optimal part placement solution manually when placing a large number of parts. For the above-mentioned reasons, we developed this 2D nesting function in Voxeldance software.

For 2D nesting, you can adjust:

  • Accuracy: the higher the accuracy, the higher is the packing density
  • Part interval: minimum distance between parts
  • Margin to sides: distance to platform border (XY)
  • Moveparts to Z height: move parts in Z direction to the setting value

1. Do not move parts, keep supports: for parts have supports,     do not move in Z direction.

2. Move parts, support need to refreshfor parts have supports, move in Z direction to the setting value

  • Rotation setting: defines, how many options you have when rotating the part along the z-axis. The more steps you have, the more options and the higher the density you will reach.

Besides these useful settings, we have some more advanced functions.

  • Selection

When you want to nest all the parts, just click All parts, all parts will be automatically nested for you.

When you want to nest only selected parts, just click Selected parts.

1. Whenever you want to place specific parts manually and let Voxeldance nest other parts around those, you can select these additional parts and click Keep unselected parts unmoved. With this option, the unselected parts won’t be moved.

Keep unselected parts unmoved

2. If you want to move unselected parts out of platform, just click Move unselected parts out of platform. All the parts unselected will be moved outside platform, only the selected be nested on the platform.

  • Align parts’ main direction to X-axis

This function is only useful for dental 3D printing. By clicking Align parts’ main direction to X-axis, all the main directions of teeth models will align to X-axis.

  • 2D nesting for round platform

Voxeldance has a special function that is nesting parts for round platform which can been hardly seen in other 3D printing softwares.
