Here's How Those Hot Jigsaw Puzzles Are Made (nytimes.com) 81
The rush to get hold of a jigsaw puzzle -- and even stockpiling by regular enthusiasts -- has transformed this quiet hobby and put companies under pressure as demand surges past Christmas levels. From a report: Ravensburger, a German puzzle maker with global sales of about $600 million, has been trying to meet the sudden blizzard of orders even as social-distancing measures have limited the number of puzzles it is able to produce at its factory in the south of Germany. The company can't easily ramp up production, because each new puzzle takes weeks to create.
Each puzzle piece must be uniquely shaped, to avoid one accidentally fitting into the wrong place. That means 1,000 different shapes for a 1,000-piece puzzle, each drawn by hand by workers. Before a puzzle is cut for the first time, each piece is sketched on a sheet of paper draped over the finished image. Pieces of metal are then shaped to form an elaborate cookie cutter made just for that jigsaw puzzle; it takes about four weeks to build one. The cutter can be used only a limited number of times before its edges are dulled. It can be resharpened once and must then be discarded. At busy times of the year, the company will go through several cutters a day. But before any pieces are cut, the company chooses the right image for a puzzle.

At least among the puzzle fans that I got to speak with there's this opinion that every piece should be uniquely shaped for some reason. Personally I do not share that opinion as I think it makes the puzzle easier if you can just go by the shape of the parts and don't also have to pay attention to the print. But I'm not into that kind of puzzle solving, so what do I know?
Anyway those 'low quality puzzles' do have their artistic application in puzzle montages [crevado.com] as well. Which might promote sales of multiple different puzzles that could make a good montage together.
I suppose that's not something Ravensburger is going for and they'd rather take pride in the fact that every piece is uniquely shaped.

The pieces for any particular puzzle can still be uniquely shaped. What I believe the parent was saying - and something I immediately thought of as well - is why not use the same pattern for multiple puzzles. You could then streamline the manufacturing of the cutters, reduce cost and improve throughput.
I can see an argument for unique shapes in the same puzzle, but the argument doesn't really hold up well across different puzzles.

The only problem I can see is that for the real jigsaw addicts, that for something like a 1k piece puzzle, they'll assemble enough of them that if they all use the same cut pattern, that the players will start memorizing piece locations based on shape.
Take something like the corner pieces. 4 unique pieces, each with 2 flat sides, and 2 sides that fit. You could easily have each on be obviously unique - one has to male connections, one 2 female, then the last two one each, but flipped from the other.

Lasers burn the material leaving scorch marks. A high quality puzzle will have the edges of the picture on each piece slightly bent down so that when they fit together, even from a small distance, there are no visible gaps in the pieces and the picture doesn't delaminate when taken apart a number of times.
A Ravensburger puzzle is relatively expensive (~$20 and up) compared to cheap puzzles from the dollar store, but the quality difference is notable.

I generally agree but lasers are used in the paper industry more than most think. A lot of greeting cards are cut that way, especially those with intricate designs cut into the card. lasers can cut like scalpels where there are very little waste between the two sides - in many cases, no more than die cutting the puzzle.
The angle down at the edges is because of the pressure of the cut, not to help the pieces fit together. That is not to say it does not help the pieces fit together :-)

One way to keep the lasers from burning the material is to flood the cutting area with N2 or CO2. No O2, no burning.
But a better solution is digital puzzles. You just drag and drop the pieces on the screen. A big 4K monitor is just as good as a tabletop. Plus, pieces never get lost.

Re: (Score:3)
Laser is a terrible, slow and expensive way to make a jigsaw puzzle.
Besides scorch marks, laser leaves a gap ("kerf") between the cut pieces because of removed material. So the puzzle pieces would not stay together and it would look awful. A sharp die splits the material cleanly so that none of it is lost in the process and the seams are tight. Compensating for the laser kerf is doable but takes work and involves cutting the shapes separately (not nested on the sheet like puzzle pieces) so it uses much more

The answer is simple. Your brain is really good at memorizing patterns.

Because then people who do a lot of puzzles will start learning the locations for particular shapes. E.g. whenever they see a corner piece, they'll instantly know which of the four corners it's for without even looking at the picture.
Unless all four corners of the puzzle share a common color, anyone is going to be able to figure out to which corner a corner piece belongs. I would suggest that by now, the puzzle creators have a huge stock of templates from which to draw. They also should have an equal stock of forms to be used to create the cutters. Go back to a template from 5 years ago and if you find a puzzle enthusiast that recognizes that pattern and complains, I'd fire that customer and move the fuck on.
