PLA+ adds a few cents per part for better impact strength. It's worth it on clips, toys and anything that gets dropped.

| Example print (preset) | $6.70 | $7.08 |
| Typical spool price | $15–25 per kg | $18–28 per kg |
| Density | about 1.24 g/cm³ | about 1.2–1.25 g/cm³ |
| Nozzle / bed | 190–220 °C / 50–60 °C | 205–230 °C / 55–65 °C |
| Enclosure | Not needed | Not needed |
Typical published ranges and mid-range prices. Example prints use each page's calculator preset. Cost per volume accounts for density: a lighter filament gives more parts per kilogram.
