High-temperature, chemically resistant SLA resin for
This technology is a specialized liquid resin formulation designed for stereolithography (SLA) 3D printing — the process where UV light cures liquid plastic into solid objects layer by layer. The key ingredient is a high-performance engineering plastic called poly(aryl ethersulfone), or PAES, which is chemically modified so it can participate in the light-curing reaction. The result is 3D-printed parts that carry the well-known properties of sulfone polymers — heat resistance, chemical resistance, and mechanical toughness — that standard SLA resins simply cannot deliver. By blending this modified polymer with reactive acrylates and a solvent system, the formulation can be processed on conventional SLA equipment.
What you could build
A commercial SLA resin product targeting aerospace, medical device, and chemical processing industries that need 3D-printed functional components — filters, housings, fluidic devices — capable of surviving harsh environments; buyers would be specialty materials distributors and industrial 3D printing service bureaus.
Who in Virginia should care
Virginia-based advanced manufacturing firms, defense contractors (given sulfone polymers' relevance to harsh-environment components), and university spinout ecosystems with access to SLA printing infrastructure would be plausible partners or licensees.
Readiness: Lab validated
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.
