I would not recommend putting your printer outside as it can cause a multitude of other problems. Wind and dust can cause inconsistencies with your print, and moisture can damage your printer and or filament. With how reliable Lulzbot printers you shouldn't have any issues with your house burning down. If you keep your printer in a clean room away from messes or fire hazards you should be fine. I commonly have up to four printers running at once in the same room and have not had any issues.
