PerranOak:
I’m trying to get into 3D printing but, of course, am having trouble choosing a printer.

It’s an impossible question to answer (i.e. which one do I get) so I’ll ask about another thing that’s concerning me.

I was shocked to see how slowly they print with YouTubers routinely talking about prints of 5, 10, 30 hours!

There is no way I’m leaving a 200degC piece of metal whizzing around in the tinderbox that is my “lab”, overnight.

Therefore, one of my criteria must be speed (the Ender 7 seems fast). Is this sensible or am I being too careful?

bdunham7:
Oh dear, no.  Speed almost always results in low quality.  I just printed a small lampshade with translucent PLA and I used 'medium-slow' (just a description, the actual settings are more detailed) settings to keep the print time to 40+ hours and although it turned out OK, I sort of regret not using even slower settings.  If you only print small things, you can limit the time to a few hours, but I routinely run multi-day prints on a not-very-large 3D printer (Ender 3 Pro).

dferyance:
You are right to be concerned about fire. There are fire alarm and suppression options for 3d printers and you can look for printers that have increased safety features.

There is only so much you can do about speed due to the way FDM printers work. If you need to make a bunch of copies there are printers that can do two at a time.

Depending on what you are making, it doesn't have to be all one part. I have a small printer so I always have to print smaller parts and join them together. Fasteners, adhesives, solvent welding, and heat welding are all options.

Lindley:
Some printers will have more self protection  than others , but never seen any site do a comparison on that point.
Would assume the more expensive the printer the better the protection ?

We use our own temperature and smoke detectors in the printers enclosure which will independantly cut the mains power and sound an alarm etc.
Also the whole room (outdoor workshop)   is covered by a smoke alarm connected to the houses buglar/ fire alarm system.

If in any doubt house it in some  isolated outbuilding/shed etc and use remote control like Octoprint which also has a camera function and believe you can also program it use a temp sensor to turn the printer off.

thm_w:
Go for speed if you want, but it will come at a large cost.

Any modern printer should have thermal runaway protection.
Combine this with:
- A smoke alarm
- A non-flammable bench/plate/enclosure for the printer
- Checking the wiring and grounding on the printer
- Crimp all wires with ferrules

and you should be fine
