3D Printing Filament Types & Properties: A Technical Reference for B2B Buyers

Most filament problems in production come down to four things:

• Color shifts between batches​ — this month’s matte black doesn’t match last month’s
• Diameter drifting past ±0.05 mm​ — random under-extrusion or jammed nozzles
• Wet spools on arrival​ — parts failing before the dryer even finishes
• No usable data sheet​ — can’t verify specs against your QA requirements

This reference compares the major 3D printing filament types and properties​ with the data procurement managers and print farm operators actually need: verified temperature and strength ranges, moisture behavior, and how these materials perform in real production environments. Where relevant, we’ve included feedback from professional printing communities to show where the datasheet ends and the shop floor begins.

The Big Four: PLA, PETG, ABS/ASA, TPU

These four materials account for the majority of FDM/FFF filament volume in B2B. Understanding their real-world behavior is the foundation of any sourcing decision.

PLA (Polylactic Acid)

Property	Typical Value
Nozzle temperature	195–230 °C
Bed temperature	45–65 °C
Heat deflection temp	~60 °C
Tensile strength	50–65 MPa
Density	1.24 g/cm³
Moisture sensitivity	Low

PLA is a bio-based thermoplastic (typically corn starch or sugarcane). It prints at low temperatures, requires no enclosure, and delivers excellent dimensional accuracy. For B2B, it’s the default for promotional items, display models, packaging prototypes, and non-functional parts.

For a deeper look at PLA variants and how PLA+ differs from standard PLA, see our PLA vs PLA+ breakdown.

PETG (Polyethylene Terephthalate Glycol)

Property	Typical Value
Nozzle temperature	220–255 °C
Bed temperature	50–80 °C
Heat deflection temp	~75 °C
Tensile strength	50–60 MPa
Elongation at break	30–50%
Moisture sensitivity	Low

PETG bridges the gap between PLA’s ease and ABS’s durability. It offers good chemical resistance (oils, solvents, alcohols), excellent layer adhesion, and sufficient heat resistance for most indoor functional parts. It’s the most common material for brackets, enclosures, jigs, and fluid-handling components.

For a direct comparison between these two, see our PETG vs PLA filament guide.
 

ABS (Acrylonitrile Butadiene Styrene) & ASA

Property	ABS	ASA
Nozzle temp	230–250 °C	240–260 °C
Bed temp	90–110 °C	90–110 °C
Heat deflection temp	~100 °C	~100 °C
Tensile strength	40–50 MPa	40–50 MPa
UV resistance	Poor	Excellent
Enclosure required	Yes	Yes

ABS is tough, impact-resistant, and vapor-smoothable with acetone. ASA matches ABS mechanically but adds UV stability, making it the correct choice for any outdoor application. Both require an enclosure and proper ventilation (styrene emissions).

TPU (Thermoplastic Polyurethane)

Property	Typical Value
Nozzle temperature	210–240 °C
Bed temperature	40–60 °C
Shore hardness	85A–95A (most common: 95A)
Tensile strength	30–50 MPa
Elongation at break	400–600%
Moisture sensitivity	Low

TPU delivers rubber-like flexibility. It’s used for gaskets, seals, vibration-damping mounts, phone cases, and wearables. It requires a direct-drive extruder and slow print speeds (20–40 mm/s). Not compatible with Bowden setups without modification.

Engineering & Specialty Filaments

Nylon (PA6 / PA12)

Property	Typical Value
Nozzle temperature	240–270 °C
Bed temperature	70–100 °C
Heat deflection temp	80–95 °C
Tensile strength	55–70 MPa
Moisture sensitivity	Very high

Nylon is the material for gears, bearing surfaces, cable ties, and living hinges. PA6 is stronger and stiffer; PA12 has better chemical resistance and lower moisture absorption. Both require aggressive drying before printing and sealed storage.

For drying protocols at scale, see our filament drying guide.

Polycarbonate (PC)

Property	Typical Value
Nozzle temperature	270–310 °C
Bed temperature	90–120 °C
Heat deflection temp	~140 °C
Tensile strength	60–70 MPa
Moisture sensitivity	High

PC survives sustained loads at 110–140 °C. It’s translucent in natural form and extremely tough. Requires a heated enclosure and hotend capable of 300 °C+.

Carbon Fiber Composites

Property	Typical Value (CF-PA example)
Nozzle temperature	260–290 °C
Bed temperature	80–110 °C
Tensile strength	70–90 MPa
Stiffness increase vs base	2–4×
Nozzle wear	High (abrasive)

Short carbon fibers (10–20% by weight) are added to PLA, PETG, PA, or PC. The result: dramatically increased stiffness, reduced warping, and a professional matte finish. The trade-off: abrasive to nozzles, reduced layer adhesion in some formulations.

PEEK / Ultem (PEI)

Property	PEEK	Ultem (PEI)
Nozzle temp	380–420 °C	340–380 °C
Bed temp	120–160 °C	120–140 °C
Continuous use temp	~250 °C	~170 °C
Tensile strength	90–100 MPa	85–95 MPa

These sit at the top of the performance pyramid. Used in aerospace, medical implants, and oil & gas. Require 400 °C+ hotends and heated chambers at 120–160 °C.

What the Community Asks Most

We aggregated the most common questions from r/3Dprinting, r/BambuLab, r/AdditiveManufacturing, and professional print farm forums:

“How do I know if my filament is actually ±0.02 mm?”

Micrometer it yourself at 10 random points across the spool. If the range exceeds 0.04 mm total, the claimed tolerance is not being held.

“Is PLA+ just marketing?”

Mostly yes. PLA+ is PLA with impact modifiers (typically elastomers or copolymers). It’s tougher and less brittle than standard PLA, but there’s no industry standard for what “PLA+” means. Ask for the actual tensile and impact test data.

“Can I print ABS without an enclosure if I use a brim?”

No. A brim helps with bed adhesion but does nothing for layer adhesion or warping in the upper layers. An enclosure is non-negotiable.

“Why does my PETG look cloudy?”

Moisture. Even a small amount creates micro-bubbles in the extruded line. Dry at 65 °C for 4–6 hours.

“Do I really need to dry Nylon every time?”

Yes. Even in a dry box, Nylon picks up enough moisture within a print session to affect surface finish. Dry for 8 hours, print, return to vacuum bag with desiccant immediately after.

B2B Sourcing: The Data Points That Matter

When evaluating any filament supplier, these are the objective criteria that separate a production-grade partner from a commodity vendor:

Diameter tolerance.​ For production use, ±0.02 mm verified by an inline laser micrometer during extrusion — not spot-checked after the fact. This keeps your extrusion multiplier consistent across batches.

Batch documentation.​ Request a Certificate of Analysis for each batch (diameter range, ovality, tensile test results, moisture content), and retain samples for at least 12 months.

Color consistency.​ For branded or matched colors, Delta-E < 2.0 between batches is the professional standard.

Compliance.​ Depending on your market: REACH/RoHS (EU), FDA food-contact (PETG/TPU), UL 94 (ABS/PC in electrical enclosures), ISO 9001/14001 (supplier quality and environmental management).

Moisture control in transit.​ Vacuum-sealed bags with> 5 g desiccant per kg, moisture barrier bags for long-haul routes, and pallet stretch-wrap with desiccant between layers. Standard cardboard with a silica sachet is not enough for ocean freight through humid climates.
