eSUN Filament Guide 2025: PLA, PETG, ABS & ASA for Every 3D Printing Need

When it comes to reliable, high-quality 3D printer filament, eSUN continues to be one of the most trusted names in the industry. Whether you're a hobbyist printing from your shed or a small business producing functional prototypes, choosing the right filament is crucial. In this guide, we'll walk you through the most popular eSUN filament options available in 2025 — PLA, PETG, ABS and ASA — helping you decide which material suits your next project best.

Who Is eSUN?

Founded in 2002, eSUN is a globally recognised manufacturer of 3D printing materials. eSUN filaments offer an outstanding balance between affordability and performance, making them a popular choice for hobbyists and professionals alike. From eco-friendly PLA to weather-resistant ASA, their range has grown to meet the varied needs of the 3D printing community.

In Australia, eSUN filament is a top pick for reliable, everyday printing — whether you're creating decorative models, mechanical parts, or outdoor enclosures.

eSUN PLA: Easy, Affordable, and Reliable

Best for: Beginners, prototypes, general-use prints

eSUN PLA is one of the most popular filaments on the market, and for good reason. PLA (Polylactic Acid) is easy to print, has low odour, and is biodegradable. It doesn't require a heated bed, and warping is minimal — making it a perfect choice for entry-level users or anyone after hassle-free printing.

Key benefits of eSUN PLA:

• Prints at low temperatures (190–210°C)
• Minimal warping and stringing
• Excellent dimensional accuracy
• Environmentally conscious

PLA is ideal for decorative prints, display models and low-stress functional parts. If you're getting into 3D printing or want reliable filament for daily use, eSUN PLA is a go-to.

eSUN PETG: Strength Meets Ease of Use

Best for: Functional parts, containers, mechanical components

eSUN PETG hits the sweet spot. PETG (Polyethylene Terephthalate Glycol) combines the strength and temperature resistance of ABS with the ease of use of PLA.

Key benefits of eSUN PETG:

• Higher strength and impact resistance than PLA
• Good layer adhesion and minimal shrinkage
• Increased heat-resistance compared to PLA
• Food-safe (in some cases, depending on handling)

PETG is perfect for mechanical parts, clips, brackets, protective covers, and tool holders. It's slightly more demanding than PLA regarding bed adhesion and stringing but still very accessible with the proper slicer settings.

eSUN ABS: Durable and Heat-Resistant

Best for: Prototypes, functional parts under stress, enclosures

eSUN ABS (Acrylonitrile Butadiene Styrene) is a tried-and-true material known for its toughness and thermal resistance. It's commonly used for parts that need to endure stress or higher temperatures — think automotive components, appliance parts, and tools.

Key benefits of eSUN ABS:

• High strength and durability
• Withstands higher temperatures than PLA or PETG
• Can be post-processed with acetone for a smooth finish

That said, ABS can be tricky to print. It requires a heated bed (90–110°C) and benefits from an enclosed build chamber to prevent warping and cracking. If you're ready to step up your material game, eSUN ABS filament is a worthy contender.

eSUN ASA: Outdoor-Ready and UV Resistant

Best for: Outdoor prints, enclosures, weather-resistant parts

eSUN ASA (Acrylonitrile Styrene Acrylate) is often referred to as an upgraded version of ABS. It offers similar strength and durability but with added UV and weather resistance. These properties make eSUN ASA filament ideal for outdoor applications — from light fittings to signage to drone parts.

Key benefits of eSUN ASA:

• UV and weather-resistant
• Strong and heat-tolerant
• Great dimensional stability

It prints similarly to ABS, so you'll need a heated bed and preferably an enclosure. ASA is the way to go for long-lasting prints that need to withstand the Aussie sun and weather.

Which eSUN Filament Should You Choose?

Here's a quick breakdown to help you decide:

Each material has its strengths, so your choice should depend on your project needs, printer setup, and environment. For beginners, eSUN PLA is the best place to start. If you need something stronger or weatherproof, consider upgrading to PETG, ABS, or ASA.
