In DigiFabster, you can set "per-sheet" costs, like "sheet loading time" and "per sheet start-up costs". Initially they will be calculated per line item, based on the bounding rectangle of the parts and the size of the selected sheet. When multiple copies are ordered, the number of needed sheets are calculated and the resulting figure is used to multiply the "per-sheet" costs.
Example: This part:
210 copies of this part, given a sheet of 2000x1000, would require 2 sheets, so the per-sheet cost would be counted twice per line item.
Once the 210 parts are ordered, they can be nested, here:
After a minute, you can refresh the page. After the refresh, you will notice that the "manufacturing" price has dropped. This is due to the fact that
a. All copies fit on one sheet
b. The resulting pattern allows two copies to take up not 200, but 150 cm2, so material consumption per part also drops.
