<p>I am wanting to buy a 3D printer to add to my shop.</p>

<p>I am an engineer and enjoy making/building things so the kit idea sounds fun and economical.</p>

<p>I see Tronxy has two different styles for their larger printers:</p>

<ul>
<li>P802 (reprap frame) style</li>
<li>X3 (metal frame) style.</li>
</ul>

<p>As far as I can see, both printers have the same basic resolution, accuracy, and material specs.</p>

<ol>
<li>What are the advantages/disadvantages/differences between the
P802 and X3? </li>
<li>How important is auto-leveling?</li>
</ol>

Some slicing programs will give this information. Here is the first comment at the end of the print, which gives volume and length of material used, from gcode generated by
Slic3r
:
```
```
; filament used = 388.6mm (0.9cm3)
```
```
According to
ToyBuilder Labs
, ABS is 1.04 g/cm
3
, so 0.9 * 1.04 =
0.936
, or just under one gram.
In the G-code file produced by the slicer, search for "filament" or "M30" - it's right after the M30. You might need to use the verbose G-code option.
