Building a heated and ABS-fume-safe enclosure
Hello guys! I am currently planing a heated and ABS-fume-safe enclosure for my new 3D Printer. But first I have some questions to ask.
Let's start with the heater. I did some research and found out that there isn't an actually simple solution for heating your 3D printer. There are several options: Heat bulbs, heat guns, hairdryers, PTC-heating elements,... After looking at these options I figured the PTC heating elements would be suitable for my application. The chamber should reach up to 70°C in order to achieve good quality ABS prints. However I have never seen PTC heating elemts in action. Does anyone have experience with this typ of heaters? Some input would be much appreciated. How do you heat your enclosures?
Secondly I've read a lot about the toxic fumes which are released during printing. Therefore I what do use a HEPA and a activated coal filter. Whats your opinion about it? Is it overkill? Does it actually help?
Looking forward to your opinions about my questions!
Happy printing :)
Toxic fumes on 3D printer
This is an evolving area, so venting outside is probably the safest option. Other people have pointed out that the two issues are 1) particulate matter addressed by the HEPA filter 2) volatile organic chemical fumes addressed by the active charcoal filter. Make sure you have both if you are running ABS or anything higher temperature.
