These are hardware-tuned starting settings for printing Silk PLA on the Voron 2.4. The Voron 2.4 pairs a direct-drive extruder with an all-metal hotend inside an enclosed chamber, and tops out at 300°C hotend / 120°C bed. Against Silk PLA's ideal range (205–230°C), that lands us at 215°C nozzle and 55°C bed. Silk PLA prints best slow and slightly hot to keep its glossy metallic sheen.
Recommended Silk PLA profile
| Hotend temperature | 215°C (tower 205–230°C) |
| Bed temperature | 55°C |
| Print speed | 56 mm/s |
| Retraction | 0.9 mm (direct drive) |
| Part cooling fan | 100% |
| Bed adhesion | Easy; print slower for the best sheen. |
| Nozzle | Brass 0.4 mm is fine |
| First layer speed | 20–28 mm/s; same bed temp, verify Z offset |
| Flow / extrusion multiplier | Start at 100%; calibrate flow before touching retraction |
| Drying | Dry if the spool pops, strings unusually, or the surface looks rough |

Calibration order
- Dry the spool if it shows moisture symptoms, then confirm the nozzle and build plate are clean.
- Print a temperature tower inside the 205–230°C range; pick the lowest temperature with strong layer bonding and clean overhangs.
- Calibrate flow, then pressure/linear advance if your firmware supports it.
- Tune retraction last — more distance is not always better, especially on the direct-drive Voron 2.4.
Silk PLA brands & what to expect
Silk PLA relies on additives for its sheen, so brands vary a lot in glossiness and clog tendency. All of them print best slower and slightly hotter than standard PLA to keep the surface shiny.

Common Silk PLA problems on the Voron 2.4
| Symptom | Likely cause | Fix |
|---|---|---|
| Dull or streaky finish | Printing too fast or too cool | Slow to ~40 mm/s and add a few degrees of heat. |
| Colour shifts / banding | Inconsistent flow on thin walls | Calibrate flow; avoid ironing which can dull the sheen. |
On the Voron 2.4 specifically: it is a fast machine, so if Silk PLA looks rough, drop speed before blaming temperature — many "quality" issues here are really the hotend not keeping up with the flow.
