1.The board game Save the Planet is an open source, cooperative game that is adaptable and customizable, making it an educational tool that grows with kids and enables creative freedom with everything from its “Good Deeds” cards to personalized game play figurines. The total cost with both 2-D and 3-D printing came to $2.89. 2. Legos
Cheap, plastic toys – no manufacturer necessary. The 2020 toy and game market is projected to be $135 billion, and 3D printing brings those profits home. People have scoffed that 3D printers are simply toys themselves. But they probably didn’t realize how much money is made off playthings. DIY manufacturing – making goods at home with a 3D printer using open source designs from a free online repository – has a multimillion-dollar impact on the overall toy industry.
The research team, led by Joshua Pearce, a professor of materials science and electrical engineering at Michigan Tech, focused on how much a desktop 3D printer could save consumers. The study investigates the 100 most popular downloaded designs from MyMiniFactory, which is one of dozens of repositories where people freely share 3D printable designs online. They used 3 different printing materials to analyze the potential costs of printing on an open source Lulzbot 3D printer – commercial filament (spaghetti-like strands easily purchased online), pellet-extruded filament (cheaper option to make filament at home), and post-consumer waste plastic (converted to filament using a recyclebot).
When a commercially available toy was available for comparison, all filament types saved consumers more than 75% of the cost and the recyclebot filament saved more than 90%. In total – and just using the data from 100 toys (less than 1% of MyMiniFactory’s repository) – people offset $60 million dollars per year in toy purchases. An important added value emerged as well: the ability to make novel toys and games that are not commercially available.
Pearce and his team also used case studies to delve more into the potential impacts of 3D printing and what might drive consumers to use DIY manufacturing. They built up one example using one of the world’s most famous and beloved plastic toys. “Speaking as a parent, Legos are expensive. All parents know you can’t find them at garage sales; everyone hoards them like they’re gold,” Pearce says. “Now you can make custom compatible blocks and have that same kind of fun while playing with something you make yourself.”
A key aspect of DIY manufacturing is judging how well the home-printed version matches the store-bought. With building blocks, an acetone-smoothing went a long way to make recycled ABS plastic look like the brand name and generic versions – with a steep cut in price. A standard Lego block costs 6 cents; the generic, 3 cents; and a recyclebot-sourced, 3D printed block is 0.5 cent.
Pearce’s team showed significant savings – typically between 40 to 90% – even with complex toys like chess sets, math puzzles, toy trucks, action figures and board games. The only time the 3D printed version didn’t save money was where the quality of the 3D print significantly surpassed commercial options; this was particularly true for large and intricate costumes and accessories used in cosplay where people dress up as characters from movies, TV shows and videogames.
Pearce says the data indicates that 3D printing is already having an impact on the industry and it will only grow as 3-D printers become more widespread. He suggests that the best route for toy and game companies is embracing 3D printing much like Ikea encouraged “Ikea hacks” with its furniture.
“One way toy companies might adapt is open-sourcing some of the designs of the toys themselves and focusing on currently unprintable components or openly encouraging the maker community and open-source community to design accessories or add-ons to commercial toys to make their toys more valuable,” Pearce says. “This is already happening – there are literally millions of free designs. Distributed home manufacturing is the future for toys but also many other products. It would be a big mistake to assume 3-D printers are just toys.” http://www.mtu.edu/news/stories/2017/july/3-d-printing-sweeping-toy-industry-off-shelves.html
