Looking at getting into 3D printing questions

I have a object I want to print I have freeCAD but I'm not 100% sure the total size of the object is but I'm sure the CTC 3D printer I'm looking at getting should be able to print it? I have a bunch of questions..

1. What type of Filament should I use PLA or ABS? It's primary use would be inside a car
2. What software do I use to print and how do I print from the files?
3. given this printer seems to be made on the outside of wood is it going to be durable enough?

If I can think of anything else I will ask

Anyone?? I really want to make sure if any improvements can be made as well

ABS will last longer, has a higher melting point and is easier to sand and shape post print.

There are plenty of free or paid for packages. I use Simply3D, which is quite expensive, but well supported and easy to use.

The plywood frame is robust and fairly rigid. There is a limit to accuracy and layer height, so don't expect miracles at this price!

3D printing is a skill and you will find there is a learning curve to getting the best out of the printer. Don't expect a perfect print the first time you hit the go button!

pet-g will last longer than abs, has higher glass point and is much easier to use and doesn't stink while printing :-)

Personally I'd go for the monoprice rather than ctc.
Lot of quality control issues with ctc machines that you don't seem to get with the monoprice versions.

I ended up getting the Anet A8 and I'm printing on PETG right now and it's a little harder to use then PLA as far as layer height and stuff like that.

Actually with petg, I'd previously only used it for very small things. Currently trying to print larger items and just can't get a clean smooth print.
So, yeah it can be problematic.
