We're MAKER



On August 20, 2016, after having discussed with team members, we decided to exclude all cram school, going abroad and camping activities and call to the Fab Lab of DRC, Taipei for a reservation in order to use the 3D printer over there. However, the answer was that they do not have a reservation system and all the 3D printers are in use. We still went there and were accompanied by some parents only on that day. Out of disappointment, the Fab Lab personnel finally let us use 3D printing pen to practice based on our own designs. This opportunity let us realize that there are infinite possibilities with such a device, because the 3D printing pen is acting like a miniature 3D printer. It ejects melted, sticky plastic base material. After cooling, the plastic base material forms unbendable, standing object. The printing pen is very compact and portable. Moreover, it can be connected to the power source using a USB 3.0 connector, which is not limited by space. Wherever you go, you can use it to print. Its advantage is that there is no limitation on the modeling of the object. The 3D printer and 3D printing pen are compared in the following table:

Item 3D printer 3D printing pen
Software Needs computer software No software needed
Diversity Able to print a variety of objects with many usable base materials Due to less base materials available, rintable objects are limited
Limitation of objects Printing objects are limited by the size of the printer No limitation, as long as the base material tube can be loaded into the printing pen
Accessibility The printer needs software to run. It cannot be used instantly. The objects must also be compatible with the machine. Accessibility is low. The printing pen functions like a welding gun. It can be used to draw objects after base material tube is melted. Accessibility is high.
