Filaments

Keeping notes on various FDM filaments here. The glass transition temperature is ideal for annealling. I've got a Google Sheet now chronicling experience with individual filaments.

Qualitative comparisons

Manufacturers employ additives to change the properties of their filaments, which I don't attempt to address here. Properties may change across different batches of the same filament. These are very rough comparisons based off oral wisdom.

• Impact strength: ASA > ABS > PC > PETG > PLA
• Tensile strength: PA >> PC >> ASA > ABS/PETG > PLA
• UV resistance: ASA > ABS
• "Chemical" resistance: PETG > ABS
• Melting temp: PC > ASA > PETG > ABS >> PLA
• Heat resistance: PC > ASA > ABS > PETG > PLA
• Printing speed:
• Offensiveness (odor, VOCs while printing): ABS > ASA, PA, PC
• Acetone postprocessing: ASA/ABS only
• Ease of sanding: PLA > PETG > ABS/ASA
• Ease of painting: PLA > PETG > ABS/ASA
• Tendency to warp: PC > ABS/ASA > PLA > PETG
• Hygroscopicity: PA/TPU > PETG/ABS/ASA > PLA
• Filament density: PETG/PLA > ABS/ASA
• Hotend temp required: PC > ABS/ASA > PETG > PLA

Tables

These data come from the manufacturers' websites and datasheets, and have not been verified. Different manufacturers report different data. These tables are not exhaustive. I have provided price in terms of USD per kilogram based on the size closest to 1kg, but many of these filaments do not have a 1kg product. I really like AtomicFilament, but I sure do wish they would publish more technical specs.
