What your production engineer actually checks
Finishing plus water treatment in one box
The M4 combines a rotary (circular) vibrator with a cleaning centrifuge and integrated process-water recirculation — so it deburrs, smooths and cleans without a fresh- or waste-water hookup. Total drive power is 2.5 kW at up to 1500 rpm, quiet at below 69 dB(A).
An applications engineer on the line
Not a ticket queue. We finish AM parts in-house (AO Metal), so media, compound and cycle advice comes from the floor. Sub-4h reply, NDA standard.
The AM Solutions M4 is a mobile 2-in-1 vibratory mass-finishing system that deburrs, smooths, mattes and cleans metal and plastic 3D-printed parts — a rotary vibrator and a cleaning centrifuge in one housing, with integrated process-water recirculation so it needs no plumbing.
Surface finishing
Polymers
MetalSurface finishing is where series production stalls
Hand-finishing 3D-printed parts is slow, inconsistent and can reach up to 50% of a finished part’s cost — and it blocks reproducible quality at volume. The M4 automates smoothing, deburring and polishing in a single machine, and treats its own process water in a closed loop, so you get repeatable surfaces with no fresh-water or drain connection.
On 316L stainless steel, mass finishing takes the as-built surface from Ra 9.5 µm down to Ra 0.7 µm — a smooth, uniform finish across a full batch, produced in one setup with the process water cleaned and recycled on board.
Why production teams run the M4
Mass finishing and water treatment in one plug-and-play machine.
Finishing + water treatment in one box
A rotary circular vibrator and a cleaning centrifuge share one housing, with integrated process-water recirculation. Deburr, smooth, matte and clean without a fresh- or waste-water hookup.
Deburr, smooth, matte, clean
Vibratory mass finishing with media and compound smooths surfaces, breaks edges and mattes both metal and plastic AM parts — an Industry 4.0 HMI keeps results repeatable batch to batch.
Larger parts and batches
A 120 L machining volume with a 273 mm working channel handles parts up to about Ø185 mm and batches to roughly 23 L — more capacity than the entry-level M1.
Quiet, mobile, plug-and-play
Below 69 dB(A), no plumbing and no installation. The M4 rolls onto the floor and starts finishing — place it beside a printer cell or move it between workstations.
How the M4 finishes a batch
Load, run the cycle, unload clean parts.
Load parts, media, compound
Place the AM parts with finishing media and compound into the 120 L bowl and select the stored cycle for the material and finish.
Vibratory finishing cycle
The circular vibrator runs at up to 1500 rpm, tumbling parts against the media to deburr, smooth and matte the surface evenly.
Centrifuge clean & recirculate
The integrated centrifuge cleans parts and the process water recirculates in a closed loop — clean, finished parts come out ready to inspect.

- Integrated process-water centrifuge — modular finishing with no fresh-water or drain connection
- Simatic HMI MTP700 touchscreen — full-colour display, intuitive menu navigation
- Compact housing tuned for low noise (<69 dB)
- Frequency-converter drive for stepless speed control
- Rotary vibrator for small and medium components
- Pallet-truck mount — move the system where it’s needed

316L stainless steel, as-built — surface roughness Ra 9.5 µm

Same part, mass-finished — surface roughness Ra 0.7 µm
Where the M4 fits
Shops that need deburring and smoothing beyond what blasting gives.
