High-temperature chemically resistant SLA resin formulation
This technology is a specialized resin formulation designed for stereolithography (SLA) 3D printing—the process where UV light cures liquid polymer layer by layer into solid objects. The key innovation is using high-performance engineering polymers, specifically poly(aryl ethersulfone) and polyetherimide, chemically modified to respond to UV light, dissolved in a printable liquid blend. These polymers are prized in aerospace, medical devices, and industrial applications for their heat resistance, strength, and chemical durability—properties that most standard SLA resins cannot deliver. The result is a pathway to 3D print parts from materials that previously could only be processed through expensive injection molding or machining.
What you could build
A licensed resin formulation sold to industrial 3D printing materials companies (e.g., resin suppliers for Formlabs, 3D Systems, or Stratasys SLA platforms) enabling them to offer high-temperature, chemically resistant SLA resins for aerospace, automotive, and medical device prototyping. Buyers would be specialty polymer and additive manufacturing materials suppliers seeking differentiated product lines.
Who in Virginia should care
Defense and aerospace contractors in Northern Virginia and the Hampton Roads corridor that rely on rapid prototyping of high-performance structural components 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.
