Programmable Powder Remanufacturing
The future of closed-loop feedstock.
Selective Laser Sintering (SLS) is an advanced manufacturing process used to produce high-performance polymer parts for aerospace, medical, and industrial applications. Using lasers and fine PA12 powder, SLS enables complex geometries and production-grade components with exceptional precision.
The Technology
During every SLS build, much of the powder bed remains unfused but is exposed to prolonged thermal cycling. Over time, this degrades the material and reduces its suitability for demanding applications. Manufacturers are forced to discard large volumes of powder and continually purchase expensive virgin feedstock.
The Problem
Current recovery methods rely on mechanical blending, cryogenic milling, or chemical processing. These approaches often introduce additional complexity, centralized infrastructure, or inconsistent material performance. Industrial additive manufacturing still lacks a practical, localized solution for recovering degraded PA12.
The Recovery Failure
What We Do
SinterNova is developing a continuous-flow remanufacturing system that combines acoustic processing and localized photothermal control to process degraded PA12 on-site. The architecture is designed to enable stable material flow and controlled particle formation without solvents or centralized recycling infrastructure.
SinterNova’s vision is to enable closed-loop material ecosystems for additive manufacturing. By improving material utilization and reducing dependence on virgin feedstock, manufacturers can lower costs while reducing industrial waste. The company’s Hardware-as-a-Service (HaaS) model is designed to integrate directly into modern production environments.
