Hello all! I'm new to both this forum & 3d printing. I have been shopping around for my first 3d printer, and am quite surprised by the wide variety on the market. Can I get some answers & recommendations from those more experienced than I am? I have questions regarding printers, scanners and capabilities of both. I know there's a lot of question that I'm asking, so please bear with me. I build full blown custom scale model cars for a hobby (1:25 scale) and want to use a 3d printer to make 1 of a kind custom parts & bodies. I have 30 years experience with building models, and think that 3d printers can take my hobby in a whole new direction. I have limited experience with CAD & blueprints so I can probably handle the design end of 3d printing.

First question: Model car bodies can be quite thin, in some areas they can tapper to less than 1 MM in thickness. The thicker areas are usually no more than a couple MM in thickness. Can I print a body? I'm thinking there would be warping & rigidity issues. Can this be addressed by reinforcing the body with some sort of gusset during the printing process? Reinforcements that can be removed after printing? Any suggestions for making something so thin that wont get warped or twisted?

Second question: Models can have very small & fine detail, such as emblems, lettering, moldings, locks, ect. What is the likelihood of being able to successfully print such small details?

Third question: In addition to printing bodies, I also want to print parts such as engine blocks, carbs, air cleaners, seats, wheels, superchargers, mirrors, ect. These parts can get pretty small. Can 3d printers make a model car part as small as a 1/4 of an inch & still show good detail?

fourth question: Would the 3d scanner in the XYZ Da Vinci AiO printer with the built in scanner be able to pick up on the fine details of model car bodies & parts (such as the details of an engine block, or the lettering, door jambs, or moldings of a model car body)? or would I be better off with a separate scanner.

fifth question: If a separate scanner is better, then which one would work best for fine details?

sixth question: Can someone recommend some CAD software that will work with both the printer & scanner?

Printer requirements so far:
1. print size of 8 inches long x 4 inched wide x 4 inches tall for a car body.
2. minimum print size for car parts would be 1/4 inch
3. My budget for a printer is no more than $700. But obviously, the cheaper, the better.
4. not interested in building a printer (d.i.y kit). Looking for plug & play.
5. No need for duel filament printers. Single color / material is fine.
6. PLA is fine, no need for ABS or exotic filaments.
7. since I am a rookie, I think the "simpler is better" approach is the way to go. So a printer that is not excessively complicated is a good idea. I'm no dummy & I'm quite familiar with machinery, but, with all the learning I have to do with 3d printing, I'm looking to simplify things if possible.
8. which printer is my best option?
9. which scanner is my best option?

I know I'm asking a lot of questions here, but I do have specific needs with a 3d printer. Just trying to avoid buying the wrong one.

I think my biggest issue is the fine detail in print quality, and of course, an affordable price.

Any answers & help is greatly appreciated.
Thanks!
