The new PQC features allow EV BMS modules to securely report state-of-charge and health data to cloud platforms without fear of future quantum decryption attacks. Ford and a Chinese EV startup (codename “Project Hydra”) have reportedly qualified the Teighax 309 v3.0 for 2026 model-year vehicles.
"Teigha" was the historical name for the SDK platform developed by the Open Design Alliance. The build number 309 is an internal version identifier that maps to the public release version 4.3.2.
It is crucial to note that ODA has transitioned away from the "Teigha" branding in recent years in favor of specific product names (e.g., ODA Drawings SDK, ODA BIM SDK). However, legacy systems and older integrations often still reference the Teigha naming convention and build numbers like 309.
Counterfeit or mislabeled chips are a real problem. To verify you have the new version: teighax 309 what is it new
Avoid any seller listing “Teighax 309” without providing the revision number or date code.
This report clarifies the release designated as "Teighax 309." In the versioning nomenclature used by the Open Design Alliance (ODA), the build number 309 corresponds to the major release version Teigha 4.3.2. This release represents a significant milestone in the evolution of the Teigha platform (now branded primarily as ODA SDKs), offering substantial improvements in visualization, data interoperability, and architectural stability.
The “what’s new” question also implies curiosity about future releases. According to a May 2025 investor call from the patent holder (Teighax GmbH, a subsidiary of a larger Swiss chemical firm), the 309 platform is intended to last through 2027. They are skipping version 310 in favor of a “Teighax Bio-400” series, but that is a different chemistry entirely. The new PQC features allow EV BMS modules
For now, Teighax 309 represents the culmination of three years of R&D focused on recyclability without property loss. Early recycling tests show that reground Teighax 309 retains 88% of virgin tensile strength after one remelt—a major step forward for circular manufacturing.
To understand Teighax 309, we must first step back. Teighax is not a single chemical but a tiered-grade series of thermoplastic co-polymers developed originally for high-stress automotive under-hood components and later adapted for 3D-printed industrial tooling.
The base Teighax line (versions 100 through 280) was known for three properties: Avoid any seller listing “Teighax 309” without providing
Teighax 309 is the ninth formula revision in the 300 performance tier. The “309” designation specifically indicates:
Unlike consumer-grade plastics (ABS, PLA, or nylon), Teighax 309 is an engineering material designed for injection molding and high-temperature powder bed fusion (a type of industrial 3D printing).
This release expanded the platform's ability to read and write complex CAD data without relying on Autodesk software.
