3D printing has been a major part of the business and education industry in the 21st century. Many people have also used it for their personal hobby. It helps to innovate the medical field which allows the development of this dual handheld bioprinting device. This device will be able to extrude two types of material, biodegradable filament and hydrogel in separate configurations. The 3D printer is used to print the prototype of this device. Customise circuit also have been developed to ensure that the device is portable, ergonomic and compatible. Both parts of the device use a micromotor for the extrusion of the biomaterial but with a different configuration. The test was done for this device to show that it is working properly. However, while doing the testing, some limitation of the device can be seen. Improvement can be done to this device such as the speed of the extrusion for the bio-ink and adjustable temperature for the 3D-printing part that suits the different types of material.
