I've always been wary of 3d printers and laser cutters because of indoor air pollution & VOCs. Though I didn't realize the amount they put out and the cumulative effects of CO as mentioned in the comments here. My sense is that laser cutters should be required to come with CO detectors, and more generally we should be looking to add the appropriate chemical detectors to 3d printers and laser printers to warn of other chemical output issues. These home machines are often advertised for use in confined spaces (size is one way manufacturers compete), which is why I think it should be regulated - its not like someone took a commercial machine home with them. Laser cutters are a fairly large capital expense and bolting on a CO detector is very inexpensive (probably <1%), and it could integrate with the cutter's electronics to prevent usage if it exceeds a certain level. Safety regulations are usually written in blood. Having two deaths with such a small # of these machines out there suggests there are probably others who have cumulative CO effects already. Very sad, my heart goes out to the friends and family of Roger & Valerie.
