3D printing may cause asthma or hypersensitivity pneumonitis

3D printing may cause asthma or hypersensitivity pneumonitis
3D printing is a relatively new technology which may be causing occupational asthma, or perhaps hypersensitivity pneumonitis. This case report shows asthma developing after what was probably high exposure to heated acrylonitrile-butadiene-styrene (ABS), with some improvement when switching to polylactic acid filaments. Unfortunately specific challenge was not done. There is an additional case report of hypersensitivity pneumonitis in a 3D printer using heated nylon, with good histology but no objective evidence of cause and effect.
