ASA Aero Lightweight 3D Printing | Cortecs Parts

Feather-light prints

Heat-sensitive foaming lets us control part density during printing, producing much lighter parts than any solid material we stock.

Keeps ASA’s weather resistance

UV, water, and temperature resistance carry over from standard ASA, so lightweight parts can live outdoors.

A deliberate trade-off

Foamed parts give up strength and surface finish in exchange for weight. The wrong choice for load-bearing or precision parts.

Applications

What ASA Aero is used for

Typical jobs we print in ASA Aero. If your part is similar to any of these, ASA Aero is likely the right choice.

RC aircraft

Wings, fuselage sections, and cowls, where grams decide flight time and handling.

Drone components

Non-structural shrouds, covers, and mounts where weight matters more than strength.

Lightweight outdoor parts

Markers, vanes, and housings that need low weight plus weather resistance.

Floats and buoyant parts

Foamed ASA Aero prints below the density of water, suiting floats, markers, and buoys (non-safety applications).

Specifications

Material properties

Values below are from the manufacturer's technical data sheet for the foaming ASA we print with (Bambu Lab ASA Aero), tested to the ISO standards listed. Data sheet specimens are printed solid; foamed parts are lighter and proportionally less strong.

Physical

Property	Method	Value
Density (solid specimen)	ISO 1183	0.99 g/cm³
Heat deflection temp.	ISO 75, 0.45 MPa	85 °C
Heat deflection temp.	ISO 75, 1.8 MPa	78 °C
Vicat softening temp.	ISO 306	80 °C
Water absorption (saturated)	25 °C, 55% RH	0.80%

Mechanical

Property	Method	Value
Tensile strength	ISO 527	32 ± 4 MPa
Young's modulus	ISO 527	2010 ± 260 MPa
Bending strength	ISO 178	58 ± 6 MPa
Bending modulus	ISO 178	1510 ± 120 MPa
Elongation at break	ISO 527	5.1 ± 1.6%
Impact strength (Charpy)	ISO 179	32.0 kJ/m²

Mechanical values are measured on solid specimens in the X–Y print plane (tensile strength approximately 21 MPa in Z). Printed parts are foamed to reduce weight, which reduces strength in proportion to the density we target: we tune the foaming level to each job. Like standard ASA, the material is resistant to acids, alkalis, and weather.

Common questions

ASA Aero printing FAQ

How much lighter are ASA Aero parts?

It depends on the foaming level, which we control through print settings on a per-job basis. The base material is already lighter than any other plastic we stock, and foaming during printing reduces the printed density further.

Is ASA Aero strong enough for RC aircraft?

It is widely used for exactly that: wings, fuselages, and cowls where loads are modest and weight rules. For high-load points such as spars and motor mounts, a solid material is often combined with it; describe the build and we will advise.

Can ASA Aero parts stay outside?

Yes. ASA Aero shares standard ASA's chemistry, so it resists UV, water, and temperature swings. It is one of the few lightweight materials suitable for outdoor use.

How much does an ASA Aero print cost?

ASA Aero is a specialty material. Upload a file or describe the part and you will receive a print and shipping price within one business day, with no obligation.
