I have to disagree, I have four (two at home) machines, two of them have a build area of 1000 mm x 1500 mm, I print full size automotive parts used for engineering testing. They are far from expensive toys, you'd be amazed at what I printed to be used as replacement parts for cars as well as countless other nonautomotive items. As far as brittle and being affected by UV light that's only because it was printed with PLA. As far as surface finish, you are mistaken, they can produce very nice finishes and the strength of ABS is 4000 PSI tensile strength!
I also do a lot of 3D scanning and I'm an expert with CAD, anything that I can think of and create in CAD, I can print it. I had to replace a number of kitchen drawer brackets that mount the rails to the rear, i couldn't find any replacements, so I removed a good one, recreated in CAD and printed a entire new set. I had a friend with an classic car, a 60 yr old defroster duct broke, created a new one, printed in ABS, it fit perfectly and he's been using it for yrs now, that and countless other examples!!
There's so many different types of filament, ASA (UV resistant) PETG, metal filled (copper, brass, wood) and many, many others.
