Low Energy Finisher

Mass Finishing

The Finishmaster series of vibratory bowl units offer the most machine for the least amount of money and are maintenance free, highly durable and offer high production capacity.

High Energy Finishers

Deburring Machines, Mass Finishing

Bel Air centrifugal disc and barrel high energy finishers are ideal for producing beautiful surface finishes on a wide range of materials used in the 3D printed or additive manufacturing process from nylon to stainless steel.

Tumbling Supplies

Tumbling Media

Bel Air Finishing develops high quality, low & high-density tumbling media for all finishing processes. We have a wide variety of plastic tumbling media, ceramic media, as well as magnetic pin & steel ball burnishing media.

Water Jet Slurry Finisher

Mass Finishing, 3D Post-Processing

Water jet surry blasters clean, descale, and degrease in a single operation without chemicals or solvents. Using a mixture of water and abrasive media, our blasters treat the parts by ‘scrubbing’ without changing close tolerance dimensions.

3D Post-Processing

3D Equipment/Supplies

FMSL 60 with separator-Centrifugal Disk Finisher

Bel Air provides a wide array of mass finishing equipment and supplies, allowing you to find finishing solutions that both fit your budget and meet your post-processing needs. Our equipment and media provide quality results on DMLS, SLA, FMO, and all other metal and plastic additive manufacturing.

3D Post-Processing

Metal Processing

3d metal Printed Processing Example

The 3D printing, or additive manufacturing, of metal parts, permits designers and manufactures to produce complex components without the need to invest in complex single-purpose, multi-stage tooling. Bel Air’s range of 3-D post-processing finishing solutions will put the finishing touch on these parts, check out our ‘before & after’ samples library:

3D Post-Processing

Plastic Processing

3d printed plastic post-processing example

There are several methods of 3d printing plastic parts with the most common being fused deposition modeling (FDM), stereolithography (SLA), PolyJet technology, or selective layer sintering (SLS). Whatever manufacturing method was used, the parts will require post-processing for surface finish and color (dyeing), check out our ‘before & after’ samples library:
