Hi just a big big big warning for ABS , HIPS and ASA. I did end up in hospital, As far as ABS is toxic is a common knowledge depends on the exposure, concentration and person( the age does not help), look a few of the professional safety requirements and warnings for plastic manufacturing. I check lately there are quite a few chemicals not in high concentration, but it builds up
My story : Got the printer second week of May and installed it in my workshop which is well insulated and almost air tide 50sqm used as a office space mostly. It is winter here so do not open too much and work for hours. After 1 week of ABS and ASA printing probably around 60+ Hours, some overnight prints got dizziness, nausea, falling down, and serious problems which send me for full emergency checks in the hospital (MRI , CT , and ā¦ bunch of other tests) At the time did not connected the dots , as i had to stop working, may be just for a short period stopped printing but was not staying for long periods around and more was in bed. Doctors was suggesting inner year or vertigo. All the tests came back normal, so was send back home from the hospital. with improvement. The next few weeks was mostly outside walk and i did more PLA , ABS, PETG printing, but was not in the workshop . June i was doing more PLA
Couple of weeks ago Mid July I got new fillaments of ABS, and HIPS and started 3d printing only ABS and HIPS , but in the mean time started working again for me that is spending lots of time in the workshop while printing. On the 3d day got dizziness back and on 4th started vomiting and went to bed followed by doctor appointment and the doctor was not sure of the cause. That was the first time clicked that may be related . After i got better went to the workshop, where another print was running and checked the air quality. We have a very good air filter and heater in the house which measures almost all air particles including has formaldehyde filter and HEPA13/14, Moved it to the workshop and turned it on, for my surprise showed over 260ppm got to around 300 at first ( the red zone finishes at 100ppm) in the house shows me usually 1-2ppm rarely will go to 5ppm , it is considered unhealthy above 100ppm and good quality air is less than 10ppm.
As the printer was working just left the air filter does its job and reduced to a number but stayed in the red zone, until the printing finished , it went down to 1ppm and hour or so after the print finished. The machine has 24hour history
Since then i stopped printing and all my symptoms disappeared, not sure if that was the only reason but definitely was a trigger or made it worse. Today i installed a ventilation on top of the printer in the area where i print , everything outside . Will see in my next ABS print, but not in a hurry to restart. I have another 100hours scheduled parts but can wait for a bit
ppm == ug/m3
Some Links after the fact i did a research:
3D Printer Fumes: Are They Dangerous to Your Health?.
Evaluation of formaldehyde, particulate matters 2.5 and 10 emitted to a 3D printing workspace based on ventilation | Scientific Reports
https://www.tapplastics.com/image/pdf/MSDS%20ABS.pdf
formaldehyde, Styrene, and others are considered not to be toxic or dangerous under normal processing conditions which includes filtration , ventilation and etc and low enough concentration
Note in air tide room the materials/fumes PM/VOC builds up. and the carbon filter of X1C is not enough
