<p><b> by Vocativ Staff</b></p><br /><p>The plain, old 3D-Printing pen just got an upgrade.</p><br /><p>The Scribbler Duo</a> has two nozzles instead of one for faster printing. All 3D-printing pens allow users to draw structures in real time and repair mistakes in larger objects.</p><br /><p>These pens can also be used by professionals for immediate prototyping or amateurs for free-wheeling drawing and design. The Scribbler Duo prints with the usual 3D-printing supplies — filaments, metal, and silk.</p><br /><br /><p>Ultimately, this isn’t a replacement for a traditional 3D printer, and some consider printing pens like this no more than a toy or a fad.</p><br /><p>If you want to try for yourself, the project is now available on Kickstarter starting at $60.</p><br /><br /> <p>The post This 3D-Printing Pen Got A ‘Double’ Upgrade</a> appeared first on Vocativ</a>.</p>
