Best Settings for IIID Max PLA+: The Complete Print Guide
IIID Max PLA+ is engineered to deliver stronger, tougher prints than standard PLA while remaining easy to work with. Whether you're dialing in a new spool or troubleshooting inconsistent results, this guide covers the optimal settings to get the most out of your IIID Max PLA+ filament.
What Makes PLA+ Different from Standard PLA?
PLA+ (also called PLA Pro) includes additives that improve impact resistance, reduce brittleness, and increase layer adhesion compared to regular PLA. IIID Max PLA+ is formulated for consistent diameter tolerance and reliable flow — which means fewer clogs and more predictable prints.
Recommended Print Settings
Temperature
- Nozzle temperature: 210–230°C (start at 220°C)
- Bed temperature: 50–65°C (60°C recommended)
- If you see under-extrusion or poor layer adhesion, increase nozzle temp by 5°C increments
Print Speed
- General print speed: 40–60 mm/s
- First layer speed: 20–25 mm/s for best bed adhesion
- Outer perimeters: 30–40 mm/s for cleaner surface finish
- IIID Max High Speed PLA+ can handle 80–120 mm/s on capable printers
Layer Height & Walls
- Layer height: 0.2mm for standard quality; 0.12mm for fine detail
- Wall count: 3–4 perimeters for strong functional parts
- Top/bottom layers: 4–5 layers for a solid, smooth surface
Infill
- Decorative/display prints: 10–15% gyroid or honeycomb
- General use parts: 20–30% gyroid or grid
- Structural/functional parts: 40–60% rectilinear or cubic
Cooling
- Fan speed: 80–100% after the first 2 layers
- Good cooling is key for sharp overhangs and bridging with PLA+
- Reduce fan speed slightly (50–70%) for very tall, thin prints to prevent warping
Retraction
- Direct drive: 0.5–1.5mm at 25–35 mm/s
- Bowden setup: 4–6mm at 40–60 mm/s
- If you see stringing, increase retraction distance by 0.5mm increments
Bed Adhesion Tips
- PEI sheet: Best option — no adhesive needed, clean with IPA before each print
- Glass bed: Apply a thin layer of glue stick or hairspray
- Blue painter's tape: Works well at room temperature
- Always level your bed before starting a new spool or after moving your printer
Drying Your Filament
Even PLA+ can absorb moisture from the air, leading to popping sounds, bubbles, and rough surface finish. If you notice these symptoms, dry your IIID Max PLA+ at 45–50°C for 4–6 hours in a filament dryer or food dehydrator before printing.
Troubleshooting Quick Reference
| Problem | Likely Cause | Fix |
|---|---|---|
| Under-extrusion | Temp too low or partial clog | Increase nozzle temp 5°C; do a cold pull |
| Stringing | Temp too high or retraction too low | Lower temp 5°C; increase retraction |
| Poor bed adhesion | Bed too cold or not level | Re-level bed; increase bed temp to 60°C |
| Layer separation | Temp too low or speed too high | Increase nozzle temp; reduce speed |
| Rough surface / bubbling | Wet filament | Dry filament at 45–50°C for 4–6 hours |
