Fastest path to a good print
PLA, PLA+, matte PLA
Start here for most visual parts and prototypes.
Tougher everyday parts
PETG, ASA, nylon
Choose based on heat, UV exposure, and printer enclosure.
Flexible or impact absorbing
TPU, TPE
Slow down, reduce retraction, and keep the filament path smooth.
Heat or outdoor duty
ASA, ABS, PC
Use an enclosure and avoid drafts.
Starting Parameters
Material comparison table
These are broad FDM starting ranges. High-speed, filled, silk, matte, and brand-specific variants can need different settings.
| Material | Difficulty | Nozzle | Bed | Fan | Speed | Enclosure | Drying |
|---|---|---|---|---|---|---|---|
| PLA / PLA+ | Easy | 190-220°C | 45-65°C | High | 60-180 mm/s | No | Helpful if brittle or stringy |
| PETG | Moderate | 225-250°C | 70-90°C | Low-medium | 40-120 mm/s | No | Strongly recommended |
| TPU / TPE | Moderate | 215-240°C | 35-60°C | Low-medium | 15-45 mm/s | No | Recommended |
| ABS | Advanced | 240-260°C | 90-110°C | Off-low | 40-100 mm/s | Yes | Helpful |
| ASA | Advanced | 245-265°C | 90-110°C | Off-low | 40-100 mm/s | Yes | Helpful |
| Nylon / PA | Advanced | 250-285°C | 70-100°C | Off-low | 30-80 mm/s | Preferred | Required |
| PC / Polycarbonate | Advanced | 260-310°C | 95-120°C | Off-low | 25-70 mm/s | Yes | Required |
| CF / GF blends | Advanced | Base material + 5-15°C | Base material range | Material-specific | 30-100 mm/s | Material-specific | Usually required |
PLA / PLA+
Best for
General models, prototypes, display parts, fast everyday printing.
Watch for
Heat creep, brittle silk blends, and poor layer bonding if printed too cool.
PETG
Best for
Functional parts, brackets, outdoor-ish utility prints, tougher everyday items.
Watch for
Stringing, nozzle buildup, over-adhesion on smooth PEI, and wet-spool bubbling.
TPU / TPE
Best for
Flexible hinges, feet, grips, gaskets, bumpers, and soft protective parts.
Watch for
Extruder jams, too much retraction, filament path drag, and wet-spool stringing.
ABS
Best for
Heat-resistant parts, tool fixtures, automotive-ish utility prints.
Watch for
Warping, fumes, layer splitting, and drafts. Ventilation matters.
ASA
Best for
Outdoor parts where UV resistance matters more than PLA/PETG ease.
Watch for
Warping, fumes, and corner lift on large flat parts.
Nylon / PA
Best for
Tough, wear-resistant parts, gears, clips, and parts that need some flex.
Watch for
Moisture, bed adhesion, warping, and softening on humid spools.
PC / Polycarbonate
Best for
High heat resistance and strong engineering parts on capable machines.
Watch for
Printer temperature limits, warping, bed adhesion, and moisture.
CF / GF blends
Best for
Stiffer parts, cleaner matte surfaces, dimensional stability, and tooling.
Watch for
Abrasive wear. Use a hardened nozzle and check manufacturer guidance.
Troubleshooting Map
When filament is probably part of the problem
Material choice and spool condition can look like slicer problems. Dry the spool and verify the basic temperature window before making a dozen profile changes.
Stringing
Wet filament, nozzle too hot, retraction too low, travel too slow.
Warping
Bed too cool, drafts, high-shrink material, poor brim/enclosure setup.
Weak layers
Nozzle too cool, fan too high, wet spool, under-extrusion.
Bubbles or popping
Moisture. Dry the spool before chasing slicer settings.
Nozzle clogs
Abrasive/filler blend, too-cold hotend, dirty nozzle, or inconsistent filament.
