So far William only has the printer extruding hot glue. 'Depending on the glue gun you used, the extruders' motors' speed will vary form program to program.' Willam said. 30 seconds later, the machine lays down the next layer.

Every layer of hot glue nees approximately 30 seconds to cool down and harden enough to support the next layer. Before starting your program, you need to first wait until the glue gun's hot enough. This printer is a lot better than the first one, but it's far from good enough.'Īs you can see in the images below, the glue gun is used as the 3D printing nozzle. I also modified the extruder, which is much more efficient now. Unlike the first printer, its' X and Y axis follow a racked track that makes it more precise. It was a prototype and the result wasn't that great.' notes Willam. 'A few months ago, I built my first 3D printer with the EV3. Instead of plastic, William's Mindstorms EV3 Lego 3D Printer 2.0 prints with hot glue. Researcher Stefanie Mueller has started using Legos in their program called faBrickator, a software program which allows users to 'legofy' their designs.Īnd recently one Instructables user named William has created a Lego 3D printer using the Lego EV3 Mindstorms system and a glue gun. Maker like Marios Papachristou has used Legos to build a special 3D printer that ressembles the design of RepRap Mendel 3D printer. #Robotic Automation Maker creates a Lego 3D printer using Lego EV3 Mindstorms and glue gun Legos and 3D printing are a natural fit for each other
