3D Printing & Additive Manufacturing Air Filtration

What Printers Release Depends on the Process

3D printing looks clean on the surface, but different processes release very different contaminants.

Standard filament printers melt plastic to build each layer. That melting gives off tiny particles too small to see, along with fumes that carry a strong plastic smell, especially with materials like ABS and nylon. Resin printers work differently: the liquid resin itself gives off strong chemical fumes the whole time it's printing, and rinsing and curing the finished print afterward adds even more. Printers that use fine metal powder bring a different problem again, since that powder can float in the air and build up if it isn't contained properly. Run a few printers together in one room without any filtration, and all of this adds up fast, especially in a small print farm or a shared office. 

Warning Signs Your Print Room Needs Better Filtration

• A noticeable plastic or chemical smell lingers near active printers

• Printers run for extended jobs in a small or poorly ventilated room

• You're scaling from a handful of desktop units to a dedicated print farm

• Staff report headaches or eye and throat irritation after long shifts

• ABS, nylon, or resin are your primary print materials

• Air quality in the print room has never been tested

Dual Filtration for Particles and VOCs

Electrocorp pairs HEPA level particulate filtration with activated carbon gas-phase stages to match what 3D printing actually emits. The HEPA stage captures the ultrafine particles generated by FDM printing and metal powder handling, while carbon adsorbs VOCs like styrene from filament and resin fumes from SLA/DLP processes. This combination covers print farms, enclosed print rooms, and post-processing or resin-washing stations where fumes tend to concentrate most.
