MODEL HP MULTIJET FUSION 3D PRINTER # 3DSPIRIT

cults3d

For this contest to highlight the design and realization of 3D objects following Additive Manufacturing technology, I chose to illustrate my point by creating a model of the HP MultiJet Fusion machine at the heart of this contest. Additive manufacturing offers a new way to design parts and requires adopting this new philosophy to open up the field of possibilities in terms of creation, design, and beyond pure mechanical design often based on traditional technology implementation. When designing a piece, we often think about how it will be manufactured: machining, plastic injection, etc. By integrating the constraints of technology (radius of curvature, material thickness, number of pieces to assemble due to limitations), we can create complex designs. Additive manufacturing, with its own set of constraints, challenges our traditional way of thinking. For this demonstration, I created a model of an HP MultiJet Fusion printer that showcases its capabilities. The 3D file shows the part as it was printed in one component, already assembled. The lid of the machine opens via a non-removable hinge (components are printed simultaneously), revealing the print head and moving parts that simulate the printing process. The trolley containing material and printed parts called the "Build Unit" can be removed from the machine and rolls on four functional wheels mounted on axes. These wheels turn and can be unmounted. Inside the Build Unit, a platform moves up and down with a locking clip in the up position, revealing a 3D-printed part (a sphere pierced with holes featuring an HP logo). The sphere turns on itself, while the logo remains fixed inside. This design showcases the ability of 3D printing to create complex objects with movements and assembly-free manufacturing. A notable aspect is the realization of a "lightened" component in terms of material while maintaining mechanical properties. This allows for the creation of lattices. The frame of the machine is made using this technique, creating a network of "mesh" that brings rigidity to a hollow part while reducing material consumption. The challenge lies in the size of this model, which fits all elements and functions within an object measuring 90mm x 45mm x 25mm. Although this object may not be of everyday use, its originality lies in showcasing the advantages of Additive Manufacturing technology through an object of communication – the HP MultiJet Fusion machine itself. I hope that this model will inspire HP to optimize and refine it for use as a communication or advertising tool (gift customers or prospects).
