AM Solutions, part of Rösler Oberflächentechnik headquartered in Untermerzbach, Germany, has launched the M4 Basic for post-processing metal additively manufactured components. Designed as a cost-effective entry-level solution, the machine is aimed at companies ready to move beyond manual grinding and polishing.

Despite its small footprint, the M4 Basic is a fully fledged vibratory finishing system engineered specifically for additively manufactured metal and polymer parts produced by processes such as Laser Beam Powder Bed Fusion (PBF-LB) and Binder Jetting (BJT). It handles workpieces up to 70 × 70 × 25 mm and offers a range of finishing options, including smoothing and grinding through to polishing and deburring.

“At AM Solutions we see a clear shift: even smaller AM users are under pressure to deliver consistent, production-grade surfaces,” stated 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 machine combines a 20 litre rotary vibrator with an integrated 25 litre process water tank, extending process-water life and reducing downtime. This closed-loop approach, together with lower water and power consumption, is designed to keep operating costs down while minimising environmental impact. Mounted on lockable transport rollers and requiring a standard 230 V connection, the M4 Basic can be moved easily and dropped into existing production environments without installation work.

“Many companies have invested heavily in printers, but their parts still pass through buckets, sandpaper and hand tools. The M4 Basic changes that equation,” Spellacy 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.”

“Quality, repeatability and efficiency in post-processing are no longer optional,” Spellacy concluded. “With the M4 Basic, we’re making that standard accessible to everyone in the AM value chain.”
