3Doodler, the world’s first 3D-printing pen (see previous coverage here), has released an innovative PRO+ model designed to meet the demands of creative professionals. the PRO+ enables architects, artists, designers and engineers to experiment with a range of materials, including metal, wood, and nylon. precision speed and temperature control are some of the new features of the pen, which offers an easy-to-use technology for the creative community to design, conceptualize, and prototype in 3D form. to illustrate the advanced capabilities of the PRO+, 3Doodler collaborated with artists and designers from around the world to create a series of ambitious doodles that reflect on 2020 events that did not occur, as well as structures that were not built to completion due to COVID-19.
