MATERIALS

Materials for
functional parts.

The right material depends on how the part will be used: load, flexibility, temperature, weather exposure, surface finish and dimensional requirements all matter.

QUICK GUIDE

Choose the material around the part, not the other way around.

PLAPolylactic Acid

A rigid, dimensionally stable material that prints cleanly and is well suited to visual prototypes, concept models and lightly loaded parts.

RigidityHigh
ToughnessMedium-low
FlexibilityLow
Outdoor useLimited
Heat resistanceLow
COMMON USES

Prototypes, visual models, jigs, fixtures and indoor parts with limited heat exposure.

Excellent when surface quality and dimensional clarity matter more than heat or impact resistance.

PETGPolyethylene Terephthalate Glycol

A practical all-round engineering material with a useful balance of toughness, chemical resistance and printability.

RigidityMedium-high
ToughnessHigh
FlexibilityLow-medium
Outdoor useModerate
Heat resistanceMedium
COMMON USES

Functional parts, brackets, covers, containers and components exposed to moisture or moderate mechanical use.

A common choice when PLA is too brittle or heat-sensitive but a high-temperature material is unnecessary.

TPUThermoplastic Polyurethane

A flexible and resilient material that can absorb vibration, repeated bending and impact.

RigidityLow
ToughnessHigh
FlexibilityVery high
Outdoor useModerate
Heat resistanceMedium-low
COMMON USES

Protective parts, flexible mounts, bumpers, grips, seals and vibration-damping components.

TPU grades vary greatly in hardness, so the required stiffness should be considered before printing.

ASAAcrylonitrile Styrene Acrylate

A durable engineering plastic valued for UV and weather resistance, making it suitable for demanding outdoor applications.

RigidityHigh
ToughnessHigh
FlexibilityLow
Outdoor useExcellent
Heat resistanceHigh
COMMON USES

Outdoor housings, brackets, automotive-style parts, fixtures and functional components exposed to sunlight.

Benefits from controlled printing conditions because large parts can warp as they cool.

ABSAcrylonitrile Butadiene Styrene

A tough engineering material with good impact and temperature resistance and a long history in functional plastic components.

RigidityHigh
ToughnessHigh
FlexibilityLow-medium
Outdoor useLimited
Heat resistanceHigh
COMMON USES

Functional housings, fixtures, mechanical prototypes and parts that require more heat resistance than PLA or PETG.

Controlled ambient temperature is useful for larger parts. ASA is usually preferred when long-term UV exposure is expected.

NylonPolyamide (Nylon)

A strong, wear-resistant engineering polyamide for mechanically demanding parts where toughness and durability are important.

RigidityMedium-high
ToughnessVery high
FlexibilityMedium
Outdoor useModerate
Heat resistanceHigh
COMMON USES

Mechanical components, wear parts, gears, bushings, fixtures and heavily loaded functional prototypes.

Polyamides absorb moisture readily and should be printed dry. Nylon grades vary significantly; always follow the specific filament data sheet.
