Microwave

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 section outlines a complete slicing and printing profile for TimeMass Microwave, tailored for printers with a 0.8 mm nozzle. If the print is not being successful, please lower the nozzle temperature by 10°C and start over until an optimal print is achieved. 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.

2. Temperature Settings
2.aNozzle Temperature: 240°C — Optimal for flowability while avoiding decomposition (which begins around 250°C).
2.bBed Temperature: 95°C — Ensures strong first-layer adhesion and prevents moisture bubbling.
2.cNozzle Temperature Range: 230–245°C — Timeplast melts around 165°C but prints best at 240°C for precise viscosity control.

3. Cooling Settings
3.aNo Cooling for First Layers: 3 layers — Prevents shrinkage due to rapid cooling of moisture-rich filament.
3.bFan Minimum Speed: 0% for the first 100 seconds — Allows heat retention during early layers.
3.cFan Maximum Speed: 15% starting at 8 seconds — Avoids overcooling that can lead to warping.
3.dKeep Fan Always On: OFF — Allows vapor to escape and avoids internal fogging.
3.eSlow Down for Cooling: ON — Improves surface finish with controlled cooling.
3.fForce Cooling for Overhangs: OFF — Overcooling can deform bridges in Timeplast.
3.gFan for Overhangs: 15% — Only for essential cooling in complex areas.
3.hPre-Start Fan Time: 2 seconds — Minimizes pressure differential during the first layer.

4. Volumetric Flow
4.aMax Volumetric Speed: 12 mm³/s — Based on a melt flow index of ~15 g/10min, allows high-speed printing.
4.bRamming Speed: 3 mm³/s — Prevents bubbles or popping from pressure spikes.

5. Retraction and Flow
5.aRetraction Distance: 0.4 mm — Minimal retraction required for soft filaments to avoid stringing.
5.bRetraction Speed: 15 mm/s — Slow enough to avoid pulling molten plastic.
5.cPressure Advance: 0.05 — Compensates for nozzle lag at high flow rates.
5.dFlow Ratio: 92% — Slight under-extrusion avoids swelling and surface artifacts.

6. Precision Settings
6.aGap Closing Radius: 0.1 mm — Tolerant of gaps in thicker walls.

7. Walls and Shells
7.aWall Loops: 2 — Minimum for strength when using a 0.8 mm nozzle.
7.bDetect Thin Walls: ON — Ensures tight geometries aren’t skipped.
7.cTop/Bottom Shell Layers: 3 — Provides good coverage; increase if watertightness is needed.
7.dTop/Bottom Thickness: 1.2 mm — Equals 1.5x the nozzle size for solid strength.
7.eTop/Bottom Pattern: Monotonic — Distributes tension evenly and improves surface finish.

8. Geometry and Movement
8.aWall Order: Inner before Outer — Creates cleaner outer surfaces.
8.bInfill First: OFF — Maintains precise outer dimensions.
8.cSmooth Speed Transition: ON — Prevents ringing caused by abrupt speed changes.
8.dSmooth Coefficient: 80 — Ideal damping for soft materials.
8.eAvoid Crossing Wall: ON — Minimizes stringing across part walls.
8.fMax Detour for Crossing: 10 mm or 5% — Balances time with print cleanliness.

9. Layer and Width Settings
9.aLayer Height: 0.3 mm — Optimal for strength and resolution using a 0.8 mm nozzle.
9.bInitial Layer Height: 0.35 mm — Slightly higher to improve adhesion.
9.cLine Widths (all): 0.8 mm — Matches nozzle diameter for consistent extrusion.

10. Seam Settings
10.aSeam Position: Aligned or Back — Use aligned for mechanical consistency, back for visual appeal.
10.bSmart Scarf Seam: ON — Automatically adjusts seam location to reduce visual impact.
10.cSeam Angle: 155° — Standard seam angle for clean transitions.
10.dSeam Steps: 10 — Smooths seam path and improves visual finish.

11. Infill Settings
11.aWall/Infill Overlap: 10% — Prevents infill from deforming soft exterior walls.
11.bInfill Combination: ON — Consolidates paths for efficiency.
11.cDetect Floating Shells: ON — Ensures unsupported vertical structures are printed reliably.
