The integration of Inkbit’s TEPU™ 30A and 50A elastomers into Stratasys Direct introduces closed-loop controlled elastomer additive manufacturing to it’s production portfolio, addressing long-standing limitations in dimensional stability and mechanical repeatability for soft materials. Delivering soft parts with unprecedented resolution and features sizes.
This collaboration brings together Inkbit’s Vision-Controlled Jetting (VCJ™) platform and Stratasys Direct’s deep experience serving industrial, aerospace, medical, and automotive customers-unlocking elastomer applications that demand not only geometric fidelity, but predictable, repeatable mechanical performance. Delivering soft parts with unprecedented resolution and features sizes.
From an industrial adoption standpoint, this partnership addresses a long-standing gap between visually realistic elastomer prototypes and true production-capable elastomer parts.
Vision-Controlled Jetting (VCJ) is Inkbit’s closed-loop additive manufacturing process that combines high-resolution material jetting with continuous optical inspection and real-time adaptive control of the print process.
Traditional jetting systems rely on mechanical planarization, where rollers physically flatten each deposited layer. This mechanical contact introduces constraints on material behavior and limits the range of elastomers that can be processed reliably. In these systems, material deposition is based on assumed flow, cure, and layer stacking characteristics. Over long builds, particularly with compliant materials, small deviations accumulate, leading to dimensional drift and inconsistent mechanical response.
VCJ removes mechanical planarization entirely. By leveraging full digital, non-contact control of the build surface and deposition process, each printed layer is optically measured and corrected in real time. This non-contact architecture enables the stable processing of soft, highly compliant elastomers such as TEPU™ materials, while maintaining tighter dimensional control.
This closed-loop, non-contact control enables:
For elastomer components, where geometry directly defines functional behavior, closed-loop control is not an enhancement. It is a requirement.
PolyJet remains a valuable technology for early-stage design validation, ergonomic studies, and visual prototyping. VCJ is designed for a different stage of the product lifecycle.
Rather than competing technologies, PolyJet and VCJ serve complementary roles-VCJ extending elastomer additive manufacturing into production-grade territory.
Inkbit’s TEPU™ elastomers were engineered specifically for VCJ and industrial use cases. Available in Shore 30A and 50A hardnesses, these materials provide rubber-like behavior with the dimensional stability required for manufacturing.
Key material attributes include:
When paired with VCJ’s closed-loop control, TEPU elastomers maintain predictable performance even in designs that traditionally challenge additive elastomer processes.
The combination of VCJ and TEPU enables elastomer applications that historically required molding, tooling, or multi-step assembly processes.
Representative use cases include:
Enabling performance-driven design rather than compromise-driven simplification.
For Stratays Direct customers, this collaboration delivers clear operational value:
From an industrial manufacturing perspective, these advantages directly address the friction points that have historically limited elastomer additive manufacturing in production environments.
The collaboration between Inkbit and Stratasys Direct represents a shift toward controlled, production-grade elastomer additive manufacturing.
By aligning closed-loop process control, engineered elastomer materials, and service-bureau-scale production expertise, this partnership positions VCJ-enabled elastomers as a practical manufacturing solution-capable of supporting real-world performance requirements with consistency and confidence.
