I reduced the layer height, and the result is very strong. The surface looks as if it is made of tiny knots.

Shader lattice on a cylinder, 1 mm layer height — 2026-09-24 (sketch 2026.09.24 shader lattice layer 1mm, commit 0f940c0)

  • Bambu Lab P1S, 0.4 mm nozzle, Textured PEI Plate
  • Syntech PETG White, Ø1.75 mm
  • Temperatures: 255 °C nozzle, 70 °C bed
  • Part cooling fan: 100%
  • Relief cylinder: radius from 20 to 28 mm (8 mm outward relief), centered at X128 Y128
  • Pattern: 10 periods around the circumference, 25.1 mm vertical period
  • Base: a continuous line along the lower contour at Z 0.2 mm, 0.5 × 0.2 mm, 20 mm/s
  • Layer height: 1 mm. First droplet layer at Z 0.7 mm (0.5 mm above the base), 50 layers total, final layer at Z 49.7 mm
  • Droplet spacing along the contour: 4 mm. Each new droplet is placed midway between the droplets of the previous layer.
  • Droplet: 2.5 mm³ on the surface, 4 mm³ on the ribs (where the contour runs radially); extruded in place at 6 mm³/s. 5140 droplets total, 5090 of them on the ribs.
  • Strand between droplets: 0.35 × 0.2 mm (0.07 mm³/mm), 15 mm/s
  • Travel across holes: 0.8 mm retraction, 0.6 mm lift, travel at 60 mm/s, descend, 0.8 mm unretraction. 719 travel moves total.
  • Print time: 71 min 19 s (excluding start and end); filament: 8847 mm
