SUNLU PLA+ ~210–220°C; the Silk PLA prints best slow and slightly hot. Below is a safe starting profile for SUNLU TPU, plus the exact numbers capped to popular printers. TPU is flexible and prints best slow with a direct-drive extruder; Bowden setups must go very slow.
Quick answer: 225°C nozzle · 50°C bed · 25 mm/s · 1 mm retraction (direct drive). Tune per spool with a temperature tower.

What to expect from SUNLU TPU
TPU comes in shore hardness grades (85A–95A most common). Softer TPU is harder to print, especially on Bowden machines. Brand matters less than shore rating and how slowly you’re willing to print.
🔎 Speed is everything with TPU — push it and the filament buckles instead of feeding. A direct-drive extruder transforms the experience; on a Bowden setup you’re limited to a crawl.

FAQ
What temperature should I print SUNLU TPU at?
Start around 225°C hotend and 50°C bed, then run a temperature tower across 210–235°C. SUNLU PLA+ ~210–220°C; the Silk PLA prints best slow and slightly hot.
Is SUNLU TPU good quality?
Cheap per kg and sold in bundles; quality is good once filament is kept dry. As always, dry the spool if you see stringing or popping and calibrate flow before judging a brand.
Do I need to dry SUNLU TPU?
Yes — TPU is moisture-sensitive regardless of brand. Dry it before printing if you hear popping or see whiskers.
