How to create a giant jigsaw puzzle

how to create a giant jigsaw puzzle

FifeX designs, creates and installs bespoke interactive products, exhibitions and educational resources. They’re based nearby in Tayport. Ken Boyd approached us to help them produce two A2 sized jigsaw puzzles for their customer, REME Museum of Technology. REME wanted to replace two puzzles that were worn out as they had been so well used by visitors.

The museum had two images that they wanted to make into jigsaws. We thought long and hard about the best materials to use and how to cut the pieces accurately, and came up with a plan.

Choosing a material

Firstly, we had to select a material to make the jigsaws from. We settled on 6mm birch plywood because it laser cuts well and wood is a lovely, chunky material to handle. Being pale in colour, the pictures would show up clearly. Also, the wood grain would be visible through the print, a lovely feature. And plywood is robust, chunky and lightweight, very important considerations when the product is designed with younger visitors in mind.

Creating the jigsaw

Once the customer had chosen the material, LaserFlair cut two A2 sized shapes from 6mm plywood and sent them to the printer. They applied the pictures and returned the panels to LaserFlair for cutting into jigsaw pieces.

FifeX found a piece of software for designing jigsaw piece layouts and shapes. It created vector lines that the laser can follow to cut the lines between the pieces. We could select how many pieces we wanted in the x and y axes, and choose regularly or irregularly shaped pieces. We decided on 20 pieces to make each piece the size that the customer wanted, and selected an irregular cutting pattern for more interest. Then we laser cut the puzzle.

The whole process was a great success. This picture shows one of the jigsaws sitting on the laser bed after cutting.
