San Francisco Coupled Died Due to Carbon Monoxide from 3D Printer

Update: This story has been edited to reflect the use of a Laser CNC, not a 3D Printer.

A couple in San Francisco, as well as their two cats, were found dead in their home last Monday. The MIT graduates, aged 35 and 32, suffered lethal carbon monoxide poisoning caused by the operation of their 3D CNC printer.

The couple were operating a laser CNC machine (previously reported as a 3D printer) system, which are typically pretty safe, but dependant on the materials you’re using to print, burning plastics and other materials can give off carbon monoxide. With some cutting jobs lasting hours, in same cases much longer, it’s easy to see how this gas could build up in a room or area that may not be well ventilated. It’s unclear the full circumstances of how the machine was being used, only that it was revealed as the source of the CO.

A GoFundMe page was started to help with costs of getting friends and family into town for their funeral, which had raised more than $15,000 in just 3 days. Our thoughts are with their families.

If you’re operating a 3D printer, laser cutter or anything similar, remember to keep the workspace ventilated and invest in a carbon monoxide alarm for your property too, as you can’t see or smell carbon monoxide, and it never hurts to play it safe. Also, be sure to check warning labels on materials to ensure they’re clean burning and safe, or prepare accordingly.

    It’s not a 3D printer, media got this wrong, its a Laser cutter (CNC machine) for cutting in steel. Stop blaming 3D printing, 3D Printing is safe. And there is no sutch thing as a “Laser” 3D printer. its a Laser cuttter (CNC machine).
    Those machines should be at ventelated spaces.

      You’re wrong on several points. The most glaring being your statement that there is no such thing as Laser 3D printing. Look up Stereo Lithographic Addition or SLA for short. I will not go into how they work but suffice to say a Ultra Violet Laser is a major component. Also 3D printers are not safe and do give off fumes the chemistry of which will depend on the resin (polymer) used. All 3D printers should be used in either a very large space where the fumes can dissipate or be vented to the outside by some exhaust system.

        Yea, SLA, ABS printers should be in ventelated spaces, but no 3D printers create carbon monoxide fumes. The only cause for carbon monoxide is from laser cutting/engraving wood

    This article is full of fallacies. this website’s a bunch of crap

    It is incredible how wrong information is published and even when they don’t know what they are talking about they still go ahead and put out the information. This was a laser cutter CNC, not a 3D printer or a 3D laser. Search that in youtube to see one in operation. The material that they were cutting probably caused the fumes that killed them.

  4. Toaster Jones says:

    While yes this article is not the most helpful on the cause of the deaths, us makers need to be careful on what chemical reactions are going on in our workshops. Investing in a Co detection device is a good idea. Also don’t neglect ventilation, the fumes might not kill you that evening but they might get you years later.
