Four mesh walls — 2026-09-24 (sketch 2026.09.24 mesh walls, commit 8953858)

General:

• Printer, filament, temperatures, and cooling are the same as above
• Four 20 × 4 × 20 mm walls (length × thickness × height) at the corners of a 100 × 100 mm square: A (78, 78), B (178, 78), C (78, 178), D (178, 178)
• The walls are printed one at a time, each in full: A, B, C, D
• Base of each wall: two solid 0.2 mm layers, 0.45 mm lines along the wall, 20 mm/s
• The wall faces run at y = ±1.2 mm from the centerline
• Strand: 0.35 × 0.2 mm (0.07 mm³/mm), 15 mm/s
• Droplets are extruded in place at 6 mm³/s
• Travel between walls: 0.8 mm retraction, lift to 1 mm above everything already printed, travel at 100 mm/s, descend, unretract
• Print time: 8 min 42 s (excluding start and end); filament: 598 mm

A “Truss” (bottom left):

• Six nodes along the wall at 3.6 mm intervals (x = −9…9), alternating between the front and rear faces to form a zigzag in plan view
• A 3 mm³ droplet at each node; node positions stay the same in every row
• Rows alternate direction
• 1.2 mm row height, 16 rows total

B “Running bond” (bottom right):

• 2.5 mm³ droplets on both faces at 4 mm intervals
• In even rows, droplets sit at x = −8, −4, 0, 4, 8; in odd rows, at x = −9, −6, −2, 2, 6, 9
• Each row is a closed loop: front face, crosspiece, rear face, crosspiece
• 1.2 mm row height, 16 rows total

C “Rails and posts” (top left):

• Seven tiers, each 2.86 mm high
• A rail is a continuous line around the perimeter of a tier. The first rests on the base (0.45 × 0.2 mm, 20 mm/s); the others bridge across the tops of the posts (0.45 × 0.3 mm, 8 mm/s). Eight rails total.
• Posts: four on each face per tier; bases spaced 5 mm apart; tops shifted 2.5 mm along the wall
• Each post is printed upward at 0.12 mm³/mm and 4 mm/s, followed by a 0.6 s pause at the top
• Post lean alternates from tier to tier
• Travel between posts: 0.8 mm retraction, 0.5 mm lift

D “Braid with stitches” (top right):

• Five nodes on each face (x = −8…8, 4 mm spacing)
• Even rows: crisscrossed strand, two zigzags between the faces
• Odd rows: ladder pattern — front face, crosspiece, rear face, crosspiece
• A stitch at each node: strand down to 0.2 mm above the row below; 1 mm³ extruded in place; strand back up; 3 mm³ droplet
• 2 mm row height, 10 rows total
