Plywood for Laser Cutting should have Improved core construction.
Improved core for clean cutting with no burn-out
When check th PO ,first check the quality is Plain or lacquered faces.
Produced with improved build quality, without any open veneers, splits, black and loose knots or knot holes both on the surface and in the core.
When doing basic project work or prototyping, this kind of issue is inconvenient but usually some trimming and sanding will sort things out. When doing a production run for puzzles like was doing, the issue is more serious:
- A jigsaw puzzle with a large number of cuts in a relatively small area has a higher chance of running into any problem spots in the material. If they exist, the laser will probably encounter them.
- Trouble spots in plywood can be on the inside layers, meaning they can’t be detected visually and are only discovered after they cause an incomplete cut.
- Increasing laser power for the whole job is an incomplete solution, as excessive laser power tends to make the cuts uglier due to increased scorching and charring.
- An inspection process becomes needed to check each puzzle piece for problems, which adds time and effort.
- A puzzle that had even one piece that did not cut properly will probably be scrapped because rework is not practical. That material (and any time and money that went into getting the nice artwork onto it) becomes waste.
