I have My DeskTop Computer and My Printer in My Bedroom.

I was going to Buy a 3D Printer but I See on YouTube they give Off Fumes that are are Toxic.

But I have 2. Bit Windows in My Bedroom and a Ceiling Fan.

Now if I Open both My Windows and put My Ceiling Fan On and Closse the Bedroom Door and Leave till it Prints will it be ok?

 

Depends on what filament you choose.
PLA and ABS are perhaps the most common. I print with both I have not noticed any obnoxious fumes.

 

PLA is quite ok.
There has been some on line comments on ABS fumes, but I do not use ABS myself so have not looked into it.
2 of my printers are inside the house and the third is in my workshop.
It is worth while reading the filament product sheets for the manufacture's recommendations.

This suggests that PLA is a safer material to use, but you should also avoid prolonged exposure to a PLA's fumes because it can be problematic.

Find a well ventilated room like the laundry.

Avoid ABS or Nylon - They emit high levels of "styrene" which is suspected to be a carcinogen. (https://www.cancer.org.au/iheard/do...ut-of-polystyrene-food-packaging-cause-cancer)

 

(I should also add that ABS is a difficult material to work with because it shrinks a lot as it cools down)

 

Plus, depending on your printers design, nearby fans can affect the quality of your printing. Parts of the object may cool too fast, resulting in weak points

 

Agreed. When printing with ABS I turn off the fans on the printer and place wind breaks around it.

 

Some sort of enclosure makes a big difference with ABS.
The one time I used ABS, I made this simple cover for the printer to keep it hot..

When I was picking up my printer (Ender 3 Pro) I was very interested in printing ABS. Another customer advised me to start with PLA, so I tossed a spool of that into my cart.

I almost finished a three "story" printer cart using three Ikea Lack tables (google that, lots of good work out there) out of PLA. Used a 2x2' sheet of 3/4" ply from HD, with casters, as the base. Great storage and easy to turn or move.

However, I never put the top on as I'm having too much fun building stuff from PLA to bother a new phase of experimenting with ABS. When I do I might make an exhaust port to blow any fumes outside (where my herb smoking neighbors can enjoy them).
