One laser-cutting file can combine cut contours with line and area engravings. After uploading, you assign an operation to each line colour. The difference is what the laser does with the path or shape.
Cutting: through the sheet
The laser follows a vector path through the full material thickness. It creates outside contours, holes, slots and cut-outs. A part that must come free needs a complete cutting contour.
The cut removes material. For fitted parts, account for kerf and actual sheet thickness. Read about tolerances and fit.
Line engraving: a path on the surface
Line engraving makes a shallow mark along a vector path. It suits outline drawings, part numbers, simple text and subtle details. The interior of a shape is not filled.
A line logo can take less time than the same logo as a large filled area. Visibility depends on material and surface.
Area engraving: filling a closed shape
The laser processes the region inside a closed vector contour. It suits filled logos, broad letters and pictograms. The area has a substantial influence on processing time.
A fill colour in your drawing software is insufficient: give the closed shape a line colour. Combine overlapping engraving shapes and preserve openings that should remain clear. Read about preparing area engravings.
A colour for each operation
Use the same colour for paths requiring the same operation. You decide which colour means cutting or engraving in the portal. The drawing guidelines show supported colours and examples.
Material shapes the result
Engraving wood looks different from engraving clear or opaque acrylic. On mirror acrylic, the reflective face is the front. Supply the desired reading direction; you do not need to mirror the file yourself. Read about mirror acrylic and the visible side.
