Purpose and goal
The goal of the project was to develop an innovative 3D wound dressing with Microfibrillated Cellulose from the forest and 3D printing technique to have an exact fit to the patient´s wound. A prototype consisting of four modules was therefore designed and produced in the project. The design and function of the various modules were based on a needs mapping that was developed within the project by the needs owner VGR. 3D printed microfibrillated cellulose was identified as a suitable material for two of the four modules and property tests were performed; absorbency, skin irritation, etc.
Expected results and effects
The project has demonstrated the possibility of using both a new process, 3D scanning in combination with 3D printing, and a new material, microfibrillated cellulose, in wound care. 3D scanning and printing makes it possible to manufacture patient-specific wound dressings with the aim of shortening the wound healing time, which can account for 80% of the cost. The microfibrillated cellulose makes it possible to use a sustainable and biocompatible material for advanced applications such as wound care. A patient specific wound dressing consisting of the four modules was produced.
Planned approach and implementation
The project began with a need mapping, which became the basis for the continued work. The mapping made it possible to understand at an early stage how the new process, 3D printing, and the material, microfibrillated cellulose, could be useful. That subsequent work utilized an agile methodology, with a dedicated team, consisting of experts from both the needs side and the technology side made it possible to design a prototype efficiently.
