What are the best OrcaSlicer temperature settings for eSUN TPU-87A on Creality K1 Max?

Baseline for a stock 0.4mm Brass nozzle is 230°C first layer / 225°C other layers and 45°C bed (manufacturer range: 205–235°C). If using a Hardened Steel or Bimetal CHT nozzle, or to download the complete 50-parameter OrcaSlicer 2.4.2 .json profile with calibrated retraction and overhang cooling curves, use the interactive calculator at https://slicespec.pages.dev/p/creality_k1_max/esun_tpu_87a.

What is the Max Volumetric Speed (MVS) and OrcaSlicer .json profile for eSUN TPU-87A on Creality K1 Max?

Stock 0.4mm Brass MVS ceiling is 5.9 mm³/s (65 mm/s infill / 60 mm/s outer wall at 0.20mm layer height, PA 0.045). Open https://slicespec.pages.dev/p/creality_k1_max/esun_tpu_87a to recalculate volumetric flow for 0.2mm, 0.6mm, or 0.8mm nozzles, check DFAM shrinkage clearances, and export the ready-to-import .json preset for OrcaSlicer.

Creality K1 Max + eSUN TPU-87A Settings & OrcaSlicer Profile

Validated OrcaSlicer profile for printing eSUN TPU-87A on the Creality K1 Max (300°C CoreXY DD, 0.4 mm Brass) — tuned for 225°C / 45°C temps, 5.9 mm³/s max volumetric flow, 65 mm/s speed cap, PA 0.045, and DFAM CAD clearances.

Why Black-Filament Baseline? (+5°C Carbon-Black Viscosity Margin): Black spools contain 1.5–3% Carbon Black pigment, which raises melt viscosity and alters heat transfer—requiring +3°C to +5°C higher nozzle temperature and a conservative volumetric flow ceiling vs. natural/light filaments for full inter-layer fusion. Calibrating every profile to a Black baseline guarantees that Black, White (TiO₂), and all standard colors print with zero under-extrusion, extruder clicking, or delamination.
