eSUN ASA+ Green 3D Printing Filament, 1 kg, 1.75 mm

eSUN ASA+ is a green, 1 kg filament listing for 3D printing outdoor and functional parts. The manufacturer describes improved interlayer strength and weather resistance, but notes that shrinkage makes temperature control and a closed printer important.

At a glance

ASA+ is presented as a modified ASA material with improved interlayer strength and bridging performance.
The listing describes weather resistance and names outdoor products and engineering accessories among its intended applications.
The manufacturer advises maintaining temperature during printing and using a closed-box printer because the filament has a large shrinkage rate.

What to know before buying

The manufacturer says to print in a closed-box printer, keep temperature stable during printing and consider glue on the build plate. Customer feedback is mixed on bed adhesion, print quality and brittleness, so results may vary.

Who is it for?

A good fit for

Owners of enclosed 3D printers seeking green ASA+ for outdoor or functional parts.
Users checking filament for model aircraft, gripping tools or engineering accessories, all listed application examples.

Less suited to

Those without a way to control print temperature or use a closed-box printer, given the manufacturer’s shrinkage guidance.
Buyers who need consistently trouble-free bed adhesion or print results, as customer feedback on these points is mixed.

Customer feedback highlights perceived quality, compatibility with model aircraft, performance and finish, including a semi-shiny appearance and light weight. Reports are mixed on print quality and bed adhesion, and on whether the filament resists brittleness. For buyers considering the stated outdoor and functional uses, those differing experiences make setup and print results relevant alongside the manufacturer’s advice about shrinkage and an enclosed printer.

Positive themes

Customers describe the filament positively for quality, model-aircraft compatibility, performance and finish.
Some customers note a semi-shiny appearance and lightweight nature.

Mixed feedback

Print quality and bed adhesion receive mixed feedback, with both successful results and reports of poor printing or prints not sticking to the bed.
Feedback on brittleness is mixed, with some describing the filament as not brittle and others as brittle.

Frequently asked questions

What filament diameter and weight are listed?

The listing specifies a 1.75 Millimetres diameter and 1 Kilograms weight.

Is this filament intended for outdoor prints?

Yes. The listing describes weather resistance and names outdoor products among its applications. These are manufacturer claims, not independently verified performance.

What printer setup does the manufacturer recommend?

It recommends maintaining temperature during printing and using a closed-box printer because the filament has a large shrinkage rate. It also says glue may be applied to the base plate.

Is bed adhesion consistent according to customer feedback?

Feedback is mixed. Some customers report good results, while others report difficulty getting prints to stick to the bed.
