AM Solutions – 3D post processing technology, a brand of the Rösler Group, has unveiled the M4 Basic, a new compact system that brings post-processing within reach of virtually any additive manufacturing user.
Designed as a cost-effective entry-level solution, the M4 Basic targets companies that are ready to move away from manual grinding, and polishing, but don’t yet need a large, high-throughput cell.
Despite its small footprint, the M4 Basic is a fully fledged vibratory finishing system engineered specifically for 3D-printed metal and polymer parts produced by processes such as SLA, SLS, MJF, and SLM. It handles workpieces up to 70mm x 70mm x 25mm and offers a wide range of finishing options (from smoothing and grinding through to polishing and deburring) in a single, plug-and-play unit.
“At AM Solutions we see a clear shift: even smaller AM users are under pressure to deliver consistent, production-grade surfaces,” says Colin Spellacy, head of UK Sales at AM Solutions. “With the M4 Basic we’re giving them a realistic, affordable way to replace improvised manual steps with a controlled, repeatable process. It’s a gateway into true industrial post-processing.”
The system combines a 20-liter rotary vibrator with an integrated 25-liter process water tank, extending process-water life and reducing downtime. This closed-loop approach, together with lower water and power consumption, keeps operating costs down while minimizing environmental impact. Mounted on lockable transport rollers and requiring only a 230V connection, the M4 Basic can be moved easily and dropped into existing production environments without installation work.
Spellacy believes the launch will resonate particularly with job shops, service bureaus, and in-house AM teams looking to professionalize their finishing workflows. “Many companies have invested heavily in printers, but their parts still pass through buckets, sandpaper, and hand tools. The M4 Basic changes that equation,” he explains. “It packages our vibratory finishing know-how into a quiet, compact system that can sit next to the printer and deliver reliable, high-quality surfaces day after day.”
Positioned alongside the larger M4 system and the rest of AM Solutions’ automated portfolio, the M4 Basic rounds out a scalable offering that supports customers from first adoption through to fully industrialized AM production.
“Quality, repeatability and efficiency in post-processing are no longer optional,” Spellacy concludes. “With the M4 Basic, we’re making that standard accessible to everyone in the AM value chain.”
