Multi-material 3D printer with contamination-free build
This technology describes an advanced 3D printing system capable of depositing multiple different materials in a single build while also achieving microscale detail in large objects. The system features a movable printhead assembly that carries both material dispensers and an integrated cleaning unit, so the nozzles or build surface can be washed between material depositions without manual intervention. A companion optical micro-stereolithography approach uses scanned light projection to cure fine features at scales typically achievable only in small-format printers, but here applied to larger builds. Together, the two subsystems address the longstanding tradeoff between print scale and feature resolution in additive manufacturing.
What you could build
A research-grade or industrial multi-material additive manufacturing platform targeting biomedical device fabricators, microfluidics researchers, and advanced electronics manufacturers who need fine features and mixed materials in one build; the integrated cleaning subsystem would be a key differentiator for regulated or contamination-sensitive production workflows.
Who in Virginia should care
Virginia-based defense contractors, biomedical device companies, and university research labs (e.g., around Blacksburg or Charlottesville) investing in advanced manufacturing capabilities would be natural licensees or collaborators.
Readiness: Prototype likely
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
