To test out how different infills affect your prints, we printed cubes measuring 3cm3 at 20% infill using our Solidoodle Green filament.
On average, filament will cost around 4.27 cents/g * 2.48 g/m = 10.86 cents per meter (or every 1000 mm). After measuring some of the filament from our store, we found that each spool has a little more than a kilogram of filament.
| Color | Full Spool Weight | Weight of Only Filament |
|---|---|---|
| White | 0.919 | 0.911 |
| White | 1.081 | 1.073 |
| White | 0.962 | 0.954 |
| Red | 0.988 | 0.980 |
| Red | 0.967 | 0.959 |
| Red | 1.027 | 1.019 |
| Brown | 1.062 | 1.062 |
| Yellow | 1.074 | 1.074 |
| Purple | 1.019 | 1.019 |
| Orange | 1.026 | 1.026 |
| Gray | 0.991 | 0.991 |
| Average | 1.006 |
Note that the white and red filament comes on white spools that weigh 0.008 kg when empty, while the other colors are on black spools that weight 0.216 kg when empty.
The infill generated depends, of course, on your model, but in our tests we found that octagram spiral used the least amount of plastic for the same percentage infill. This also meant that this infill printed the fastest, as there was less filament that had to be extruded.
