Passive

1. Introduction
These parameters are designed to help avoid printing issues; however, temperatures and speed timings can be adjusted based on your specific goals. For example, if you prefer a less rigid result, we recommend using a lower temperature. This is the printing guide for TimeMass Passive filament as tested on the Bambu Labs A1. This filament features extremely low moisture exchange, high structural stiffness, and requires higher thermal energy for optimal melt and flow. While these examples were printed with a 0.8 mm nozzle, TimeMass can be used with any nozzle size. Please check the manual for printing parameters with all the other nozzle sizes.

Because TimeMass Passive releases minimal vapor but has high melt resistance and moderate elasticity, these profiles focus on thermal force management, mechanical flow stability, and precise extrusion tuning.
If the print is not being successful, please lower the nozzle temperature by 10°C and start over until an optimal print is achieved.

2. Temperature Settings (All Nozzles)
2.a 0.2 mm Nozzle — Nozzle Temp: 235°C | Bed Temp: 70°C — High energy needed to soften the matrix
2.b 0.4 mm Nozzle — Nozzle Temp: 245°C | Bed Temp: 70°C — Better melt performance through standard nozzle size
2.c 0.6 mm Nozzle — Nozzle Temp: 250°C | Bed Temp: 70°C — Elevated flow demand for thick lines
2.d 0.8 mm Nozzle — Nozzle Temp: 255°C | Bed Temp: 70°C — Necessary thermal energy to prevent partial fusion at large diameter

Note: Heatsink fans must remain consistent. Bed adhesion improves with light glue stick.

3. Cooling Settings (All Nozzles)
3.a No Cooling for First Layers: 2 — Less needed due to stiffer filament body
3.b Fan Minimum Speed: 20% at 50 seconds — Starts cooling sooner to shape rigid geometry
3.c Fan Maximum Speed: 25% — Supports layer definition without cracking
3.d Keep Fan Always On: ON — Essential for shaping passive structure
3.e Force Cooling Overhangs: ON — Encourages clean bridges for long spans
3.f Fan for Overhangs: 25–35% — Passive holds angles well, supports sharper fan control

Note: Timeplast Passive benefits from continuous airflow and structured cooling logic.

4. Max Volumetric Flow
4.a 0.2 mm Nozzle — Max Flow: 2 mm³/s — High-viscosity structure needs conservative flow
4.b 0.4 mm Nozzle — Max Flow: 5 mm³/s — Standard flow, safe and precise for rigid plastic
4.c 0.6 mm Nozzle — Max Flow: 9 mm³/s — Accommodates increased demand for high-mass lines
4.d 0.8 mm Nozzle — Max Flow: 13 mm³/s — Delivers clean, full-fused thick walls

5. Retraction & Pressure Advance
5.a 0.2 mm Nozzle — Retraction: 1.0 mm @ 25 mm/s | Pressure Advance: 0.03
5.b 0.4 mm Nozzle — Retraction: 0.8 mm @ 20 mm/s | Pressure Advance: 0.04
5.c 0.6 mm Nozzle — Retraction: 0.6 mm @ 18 mm/s | Pressure Advance: 0.045
5.d 0.8 mm Nozzle — Retraction: 0.5 mm @ 15 mm/s | Pressure Advance: 0.05

Note: Low moisture = less stringing, but retraction is still key for clean transitions.

6. Layer Height and Line Width
6.a 0.2 mm — Layer Height: 0.12 mm | Initial: 0.18 mm | Line Width: 0.25 mm
6.b 0.4 mm — Layer Height: 0.2 mm | Initial: 0.22 mm | Line Width: 0.42 mm
6.c 0.6 mm — Layer Height: 0.3 mm | Initial: 0.32 mm | Line Width: 0.6 mm
6.d 0.8 mm — Layer Height: 0.3 mm | Initial: 0.35 mm | Line Width: 0.8 mm

Note: Clean lines support Timeplast Passive’s structural stiffness.

7. Wall, Shell & Infill Settings
7.a Wall Loops — 0.2 mm: 3 | 0.4 mm: 2–3 | 0.6 mm: 2 | 0.8 mm: 2
7.b Top/Bottom Shells — 0.2 mm & 0.4 mm: 4 | 0.6 mm & 0.8 mm: 3
7.c Top/Bottom Thickness — All: 1.2 mm (except 0.2 mm at 1 mm)
7.d Sparse Infill Density — 0.2 mm: 25% | 0.4 mm: 20–25% | 0.6 & 0.8 mm: 15–20%

Note: Strong shells help support high stiffness and dimensional precision.

8. Speed & Acceleration
8.a Travel Speed — 0.2 mm: 120 mm/s | 0.4 mm: 140 mm/s | 0.6 mm: 150 mm/s | 0.8 mm: 160 mm/s
8.b Outer Wall Speed — 35 / 45 / 55 / 65 mm/s (increasing by nozzle size)
8.c Infill Speed — 70 / 100 / 120 / 130 mm/s
8.d Acceleration (Print) — 1200 / 1800 / 2200 / 2400 mm/s²
8.e Acceleration (Travel) — 3000 / 3500 / 4000 / 4500 mm/s²

Note: Passive resists flex — high-speed print motion is safe and reliable.

9. Adhesion & Brims
9.a Skirt Loops: 1–2 — Clears dense first-line flow
9.b Brim Width: 5 mm — Secures stiffer corners to plate
9.c Brim Gap: 0.15 mm — Moderate release force to match rigidity

10. Flush, Prime & G-code

10.a Prime Tower: Optional — Low moisture means less need for purging

10.b Start G-code:
