    Less is more
    The maximum size of printed object is 8 x 8 x 8cm , which is relatively small than many other 3D printer. However, it is already large enough for making things like figure and toy.
    The gain from the trade off is the cost down of material and maintenance. Take out components for making large printed object , the design become simple and lean. The core material is acrylic sheet and connected by metal screw. Therefore , the cost of material and building can be minimized.
    Easy to build / Learning by making
    The process of making has the opportunity to transform education by inviting students to be something other than consumers of education. They can be maker of anything , moving from being directed to self-directed through the process.
    Tinyboy is designed for easy to build. The assemble from kit can be done by just using a screw driver. We wish student can make their own machine. Then they become a pioneer whose may make another one for other people. So that the use of 3D printer can be spread out to more student.
    The case of TinyBoy uses acrylic plane as the main material. Individual parts can be made by using cutter laser. Therefore, the manufacturing process is easy once you have a laser cutter. In fact , the price of an A5 laser cutter can be as cheap as USD $400. That make the cost of small amount production be reasonably low.

    "Tinyboy 3D Printer for Kids"

    From what age?

    the printer is 150mm x 150mm x 240mm which is small enough for Kids to handle while Year 4 to Year 12 from primary/secondary school are the best..

    the maximum print size is only 80mm x 80mm x 80mm but can make a robot figture with joint for about 400mm in height.

    robot figure can find from

    what does it cost ?
    Absolutely no clue on your website - which is apparently stuck in 2016.

    Also no specifications, or indication why having an exposed hotend they can poke is good for kids.

    we have got a fan cover on the hotend to prevent touch of it. is our inital project page since 2013~2016 with TinyBoy 1 ~ TinyBoy 2
