No More Post-Processing Bottlenecks: The AM Solutions M1 Automates Four Finishes in One Box
From deburring to polishing, the upgraded and compact M1 system eliminates manual labor by running multiple surface treatments simultaneously—addressing one of the biggest hurdles in serial additive manufacturing.
Post-processing remains the single most expensive bottleneck in additive manufacturing, often devouring more time and labor than the 3D printing process itself. While printer throughput has skyrocketed, finishing has stayed stubbornly manual outside of a few automated systems. Germany-based AM Solutions (a Rösler Group brand) is one of the leaders in the market and has just unveiled its redesigned M1 system, a compact machine designed to automate smoothing, polishing, grinding, and deburring of both polymers and metals in a single, multi-stage workflow.
According to the company, the upgraded system replaces the previous M1 Basic and introduces new workflow, process stability, and automation enhancements.
Positioned as a flexible post-processing solution, the M1 combines a menus of finishing in a single machine. It supports parts up to 550 × 150 × 130 mm, either individually or in small batches, and features a divider system allowing up to three finishing steps to run simultaneously without changing media.
“The first M1 Basic proved how powerful vibratory finishing can be for additive,” says Colin Spellacy, head of UK sales at AM Solutions. “But our customers asked for more flexibility, better ergonomics, and even higher process stability. The new M1 is our answer. It turns what used to be an entry-level solution into an advanced production tool.”
AM Solutions has not released a price for the upgraded M1, but the M1 basic retailed for around $32,000.
Bridging the AM finishing bottleneck
AM Solutions positions the M1 as a bridge between entry-level finishing and fully automated industrial lines. The system’s redesigned processing trough includes end-side profiling and additional partitions, enabling multi-stage finishing recipes in a single setup. A new separation concept moves media and part separation onto a dedicated material cart, improving handling efficiency and overall throughput.
The system also adds a fresh-water connection compatible with AM Solutions’ Keramo-Finish® process media, enabling higher surface quality finishes. Users can run either closed-loop water recirculation or fresh-water operation, depending on process requirements.
“For many AM users, the real bottleneck isn’t printing, it’s finishing,” Spellacy adds. “With the relaunched M1, we’re giving them a robust, repeatable and economically attractive way to turn rough builds into market-ready products, without jumping straight to a large, fully automated line. It closes the gap between R&D and industrial production.”
Compact Design for Alongside AM Systems
Despite its expanded capabilities, the M1 retains a compact footprint and mobile design. Plug-and-play integration, low noise levels, and an integrated settling tank allow it to be placed directly next to 3D printers or integrated into existing finishing cells. The system also includes a modern HMI interface with automated process control via PLC, helping ensure repeatability and reducing operator intervention.
This approach reflects a growing industry trend toward modular, scalable post-processing solutions that can evolve alongside production needs. Instead of requiring immediate investment in large finishing lines, manufacturers can adopt smaller systems and scale gradually.
Expanding Scalable Finishing Options
The M1 launch reinforces AM Solutions’ strategy of providing scalable post-processing technologies across different production stages. The company, part of the Rösler Group, draws on decades of experience in mass finishing and shot blasting across multiple industries.
With additive manufacturing moving steadily toward serial production, reliable and automated finishing is becoming increasingly critical. Systems like the M1 aim to make professional-grade surface finishing more accessible, particularly for companies transitioning from prototyping to low- and mid-volume production.
As additive manufacturing matures, improvements in post-processing automation—rather than printing speed alone—may play a decisive role in enabling wider industrial adoption.
