Formlabs has filed a patent for an integrated post-processing system that combines centrifugation, solvent washing, and UV curing into a single automated unit for resin-based 3D printing. The patent describes a mechanism designed to handle the transition of parts between these stages without manual intervention, specifically targeting the removal of excess liquid resin from complex geometries. By automating the workflow for SLA and DLP platforms, the system aims to reduce the labor-intensive post-processing steps currently required for high-precision photopolymer parts. This development originates from the Somerville, Massachusetts-based company, which continues to focus on refining the end-to-end user experience for its professional-grade desktop and benchtop hardware.

Post-processing remains a significant bottleneck in the adoption of SLA and DLP technologies, often accounting for a disproportionate amount of total production time. While competitors like Carbon and Stratasys have developed their own automated washing and curing solutions, Formlabs is seeking to further consolidate the physical footprint of these units. Integrating a centrifuge is a notable addition, as it effectively clears resin from internal channels and blind holes that standard agitation or ultrasonic baths often fail to reach. This move aligns with the broader industry trend of moving toward lights-out manufacturing and reducing the variability introduced by manual handling in resin-based additive workflows.

For users, this patent indicates a potential future hardware iteration that prioritizes throughput and consistency over manual batch processing. If commercialized, the success of this system will depend on its ability to handle diverse resin viscosities and part geometries without damaging delicate features. Buyers should view this as a potential roadmap for future Formlabs ecosystem expansions rather than an immediate product availability announcement.
