Metal Surface - Gen 2

Click here to access our new and improved TimeMass GPT Assistant. Just tell it your printer model and the TimeMass filament you're using—it will instantly recommend the exact parameters you need to start printing successfully.

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 Metal Surface, 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. Please check the manual for printing parameters.

2. Temperature Settings
2.aNozzle Temperature: 230°C — Optimal for flowability while avoiding decomposition (which begins around 250°C).
2.bBed Temperature: 75°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.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.
11.dSparse Infill Density: 20–25% — Balanced rigidity vs. material use.
11.eSparse Pattern: Grid — Stable and efficient for flexible geometries.

12. Speed Settings
