Business Development & Sales Intern
Printerior
About Us Printerior is transforming manufacturing through mass production 3D printing. We operate high-throughput print farms using FDM, SLA, and SLS technologies to deliver production-grade parts in days, not months.

We also lead in the development of large-format additive manufacturing (LFAM) for architectural and industrial-scale components.
