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
