How to recycle filament material from printed parts?
If you're more interested in the recycling and reuse aspect than the re-print aspect, you could melt all the scrap filament onto a cookie sheet or into a bar (like in a bread ban). You could then ...

"Tac Tac" sound when printing with ABS
@Ecnerwal is right: that noise you hear is the extruder not being able to push the filament, and the stepper can't push any harder. When the extruder tries to push harder than it can, it gives up, and ...

How many grams will be used in a print
You can not tell this by looking at the STL file alone, because how much material will be used depends on the print settings (obviously, printing at 100% infill will consume much more material than 10%...

Best method to make dissolvable supports?

Is there a way to print with ABS without enclosure?
There is no requirement for an enclosure when printing ABS. Like many things in FDM, there are improvements to be made, but there is a scale of what is possible.

Good filament/s for heat resistance in cars
ABS, or preferably ASA which is "a better ABS", is probably your main option. ASA holds up better under UV/sunlight and is easier to print (less warping). Like ABS it should be printed with ...

What is this called and how do I avoid it? (model frees itself from support structure and warps upwards)
What is this called
This is called warping.
Warping of prints occurs frequently when you use a filament that shrinks. If the model would shrink uniformly, it will become smaller, like in a scaled ...

Printer changing temperature after selecting file
The demo files are gcode files generated for use with the sample PLA that comes with the printer. If you want to print it with ABS select the file and set the temperature manually afterwards.

What's smoother? Acetone treated PLA or ABS
ABS filaments will smooth well with using acetone, it's been used for a while now.
For PLA filaments it's a different story, pure PLA will not smooth out in acetone and it will likely only cause ...
