3D Nesting

Nesting is a process in which parts are re-arranged within a printer space in an optimal way by translating or rotating the parts (or both), based on predefined directives.  The purpose of nesting is to reduce manufacturing costs by having parts occupy less space and by that saving expensive material and printing time.  This optimization of material usage by nesting parts plays a major role in many manufacturing processes where there is a continuous strive to improve density and lower the height of production batches.  3D nesting has become an essential part of the workflow as more and more service bureaus and manufacturers are improving their production process aiming to increase profitability.

3D nesting, however, brings about tremendous challenges. While box-shaped parts may be relatively easy to nest, in practice the majority of parts produced in the industry have complex and irregular geometries, which make nesting a substantial challenge requiring advanced algorithms and sometimes a great amount of computation power. The 3D nesting by Assembrix is cloud-based and so all computations are done on the cloud saving the heavy lifting on the PC.
Additionally, Assembrix’s nesting tool offers maximum flexibility with the following capabilities:

  1. Selective Nesting: It allows applying nesting only on selected parts (or on the whole assembly) – this is useful when nesting selected parts in a volume that already contains other parts, without having the latter nested again. Service bureaus can add more parts and combine them with an existing printing batch without changing the original build.
  2. Flexible nesting rules: It allows applying special nesting rules (e.g., separation from other parts, allowable transformations) to specific parts or selected group of parts. This means it is possible to create a hierarchy of nesting rules where part-specific nesting rules are taken into account before general nesting rules are applied to the rest of the assembly.
  3. Full-range-orientation: It allows testing for an unlimited continuous range of part orientations, not restricted to increments of fixed degrees. Assembrix’s tool ensure that a full range of possible orientations is checked, in order to achieve the best results or cater to technology-specific requirements.
  4. Parallel nesting: It allows running several different nesting scenarios in parallel, comparing the results and choosing the best one to be printed. With Assembrix’s limitless computing resources, operators can save time and money while getting a broader view on different printing options.
