NIOSH
A capture device to reduce ultrafine particle emissions near the nozzle of Rep+ 3D printer. The local exhaust ventilation control attaches to a Rep+ 3D printer extruder to capture ultrafine particle emissions generated from filaments used in the fused deposition modeling 3D printing process.
Should be printed at or close to 100% infill to provide a strong and airtight part. This part was designed to connect to a standard CPAP hose and other off-the-shelf items that can be purchased from a variety of sources.
Make sure all internal pathways are completely clear of supporting material.
3D print files were designed by the National Institute for Occupational Safety and Health (NIOSH) and evaluated during laboratory and field studies in collaboration with Makerbot Industries, LLC.
