Nesting is the merging of several parts into one drawing.
Do you have a lot of small parts? Or parts that fit well next to each other. Then nesting can be advantageous.
Nesting is not beneficial for all types of parts. Here we explain everything you need to know about nesting.
When to nest?
Nesting can be beneficial when you need several parts of the same material, especially if they are small parts.
Nesting can also be beneficial when parts fit easily next to or inside each other. It can save costs by reducing residual shape in a drawing, or by sharing cutting lines and reducing production time.
Nesting is not a requirement.
When not to nest?
Nesting is never a requirement. But it may be more advantageous to put parts together on a plate.
Need multiple copies of the same part? Even then you don't need to nest. Upload the drawing of the part and choose the desired quantity in the ordering process. The website automatically calculates the quantity discount; the unit price goes down for higher quantities.
Only if your parts are shaped to fit together conveniently is it sometimes more economical to nest yourself anyway.
How to nest?
You create a nest in the same way as a regular laser drawing. Use the correct layer name and line color, as described in the drawing rules.
- Enlarge your artboard or drawing area, note the maximum material size
- Copy the parts to the nest drawing
- Find an efficient layout, leave 2 mm between parts
Leave a space of at least 2 mm between parts to prevent burn-in and smoke deposits.
For foams, this should be at least 4 mm.

Share cutting lines
You can put parts against each other so that they share one cutting line.
For example, if you put two rectangles against each other, you can theoretically cut two parts loose with one line. This saves costs because the total cutting length and production time is then shorter.
Remove duplicate lines from your drawing after you put shapes together.
Share cutting lines is not possible in the following cases:
- Small parts (precision cannot be guaranteed).
- Precision parts (precision cannot be guaranteed)
- Round corners
We cannot guarantee dimensional accuracy on parts with split lines.
