I need advice about 3D printing original humanoid files.

[curious aardvark]

the rule of thumb is: moving vertically up the model, if you come to a point where part of the model is by itself in midair - you will need supports.
Thigh gap is not your friend. Hell you need to be anorexic to have one anyway.

Do what Roxy said :-)

far as the printers go: https://tevo3dprinterstore.com/produ...3d-printer-kit
I'd get a tevo little monsteer.

reason being pushing a strand of 1.75 mm filament as far as you do on both the cnc machines is going to result in problems. A pure bowden setup on a delta is fine, but when you're dealing with a lot of height, you have a long bowden tube and that's going to cause issues.
You might get away with it if you used 3mm filament. But I just wouldn't want a bowden tube that long on any printer.

The tevo, gets around this with a suspended extruder and a bout 6 inches of tube.
When you look around at the big industrial delta's they all have suspended extruders.
Has several advantages. Works almost as well as a direct drive extruder, so you can easily use flexible filaments - not a hope in hell with the cnc's. Prints faster and with more precision. retractions don't need to be ridiculously long.
Essentially you get the best of both worlds. The ease of use of a direct drive extruder with the speed and height of a delta.

Oh yeah and it's quite a bit cheaper as well :-)
The tft touchscreen also has a connector port for a wifi module should you want that.
