Abstract

Binder Jet 3D printing is an additive manufacturing technique that utilizes a binding agent to form each layer on a powder bed, ultimately producing a complete part. This method is advantageous for manufacturing due to its ability to handle a diverse range of materials while achieving high complexity and density in printed parts. Currently, industrial Binder Jet 3D printers range in price from $100,000 to $1 million, and they require significant space and energy within a manufacturing facility. Many engineers would benefit from a smaller, more energy-efficient binder jetting solution that allows for rapid testing of printed parts before full-scale production or the prototyping of small-scale components.To address this need, our team has developed a small-scale desktop Binder Jet printer subassembly. The primary focus of this design is to minimize cost, reduce print time, and decrease the printer's footprint, all while maintaining the desired complexity and precision of the parts produced. This paper presents the current design and construction of the proposed device, along with key findings to inform future developments.
