SUNLU Easy ABS Filament: The Best Solution to Traditional ABS Warping Problems in 3D Printing

If you're a 3D printing enthusiast, you've likely battled the frustrations of traditional ABS filament: severe warping, corner lifting, layer cracking, irritating fumes, and the constant need for a fully enclosed printer with high chamber temperatures.

Traditional ABS offers excellent strength, heat resistance, and durability for functional parts like automotive components, tool handles, and enclosures. However, its high shrinkage rate and sensitivity to temperature changes make it notoriously difficult to print successfully—especially on open-frame printers or in cooler environments.

Enter SUNLU Easy ABS filament (also called E-ABS). This modified ABS formulation is engineered to deliver the core benefits of standard ABS while dramatically reducing the most common pain points. With lower printing temperatures, significantly reduced warping and shrinkage, minimal odor, and better bed adhesion, it's becoming a go-to choice for both beginners and experienced makers.

In this article, we'll break down why traditional ABS warps so badly, how SUNLU Easy ABS solves these issues, recommended printing settings, real user experiences, and actionable solutions based on community feedback.

Why Traditional ABS Filament Warps So Much

Warping occurs when the printed part cools unevenly, causing internal stresses that pull the corners or edges away from the build plate. Traditional ABS is particularly prone to this due to:

• High thermal shrinkage (around 0.8% or more)
• Sensitivity to drafts and ambient temperature fluctuations
• Poor layer adhesion if cooling is too aggressive
• High required bed (90–110°C) and nozzle temperatures (240–280°C), which amplify temperature gradients

Common complaints with standard ABS include:

• Corners lifting on large flat parts
• Cracking between layers
• Strong "plastic smell" during printing
• Need for enclosures, glue sticks, hairspray, or brims/rafts to improve adhesion

These issues lead to failed prints, wasted filament, and frustration—especially for users without advanced setups.

How SUNLU Easy ABS Filament Fixes ABS Warping Challenges

SUNLU designed Easy ABS as an "effortless" evolution of traditional ABS. It incorporates specialized modifiers that improve flow, reduce shrinkage, and enhance interlayer bonding without sacrificing too much of ABS's signature toughness.

Key Advantages of SUNLU Easy ABS vs. Traditional ABS:

• Ultra-low warping and shrinkage: Users report it stays flat even on larger prints, often succeeding on open printers with minimal drafts.
• Lower printing temperatures: Nozzle 225–255°C and bed just 60–70°C (much easier on hardware and energy use).
• Reduced odor: Significantly less irritating fumes, making it more pleasant for home or office use.
• Better bed adhesion: Prints stick well with standard PEI plates; many users need little to no adhesive.
• Improved layer adhesion: Stronger bonds reduce cracking and delamination.
• Wider printer compatibility: Works reliably on Bambu Lab A1 series, Prusa, and other open or partially enclosed machines.

While heat deflection temperature may be slightly lower than pure ABS (closer to high-end PETG in some tests), it still delivers solid impact resistance and mechanical properties for most functional applications.

Ideal uses include electronic housings, brackets, automotive interior parts, durable tools, jigs, and protective cases.

Recommended Printing Settings for SUNLU Easy ABS

Getting great results starts with the right profile. Here are optimized starting settings based on SUNLU recommendations and user successes:

• Nozzle Temperature: 225–255°C (start at 240°C and tune with a temperature tower)
• Bed Temperature: 60–70°C
• Printing Speed: 50–200 mm/s (slower for first layers and detailed parts)
• Cooling Fan: Can be turned on (unlike standard ABS, which usually requires 0–10%)
• Layer Height: 0.2 mm standard; 0.12–0.28 mm works well
• Enclosure: Not required for most prints, but helpful for tall or very large models (>10 cm). A simple cardboard box or partial enclosure can stabilize results.

Additional Tips for Success:

• Dry the filament if it has been exposed to humidity (50°C for 4–6 hours).
• Use a brim or raft for very large or thin-base parts.
• Print in a draft-free area.
• Clean the build plate thoroughly (isopropyl alcohol works great).

Many users successfully print SUNLU Easy ABS on Bambu Lab printers using generic or modified ABS profiles with these adjustments.

Real User Feedback on SUNLU Easy ABS Filament

Community experiences are mostly positive, with many praising its printability:

• "Warping and cracking reduced by 99%... printed smoothly even on an open printer."
• Excellent for users tired of fighting standard ABS on non-enclosed machines.
• Lower odor makes long prints more bearable.

Some constructive feedback includes:

• Slightly lower heat resistance compared to pure ABS (may not suit extremely high-temperature applications).
• A few reports of surface quality or minor clogging issues if temperatures aren't dialed in precisely.
• Dimensional accuracy is generally good but may need calibration for precision fits.

Overall, most makers agree that SUNLU Easy ABS makes ABS accessible without requiring a full high-end setup. It's particularly loved by hobbyists who want functional strength without the headaches.

Solutions to Common ABS Warping Issues (Even with Easy ABS)

Even with an easier filament like SUNLU Easy ABS, here are proven solutions for stubborn warping problems:

1. Improve First-Layer Adhesion Level your bed perfectly. Use a clean PEI plate. Add a wide brim (8–12 mm) or raft for large parts. Some users apply a light layer of glue stick or hairspray as backup.
2. Control Temperature Gradients Avoid strong drafts—close windows and turn off AC vents nearby. For taller prints, add a simple enclosure or draft shield in your slicer.
3. Optimize Cooling and Speed Print the first few layers slower. Balance fan speed (Easy ABS tolerates more cooling than standard ABS). Use higher min layer time settings for small parts.
4. Filament Drying and Storage ABS variants are somewhat hygroscopic. Dry filament before use and store with desiccant.
5. Design Considerations Avoid sharp 90° corners on large bases—add fillets or chamfers. Orient parts to minimize long flat areas on the bed. Use gradual infill patterns.
6. Slicer Tweaks Enable "elephant's foot compensation" if needed. Experiment with bed temperature ±5°C and nozzle temperature in 5°C increments.

Following these steps resolves most warping cases, even when switching back to traditional ABS for maximum heat resistance.

Conclusion: Is SUNLU Easy ABS Worth It?

For most 3D printing users, SUNLU Easy ABS filament is a smart upgrade that solves the biggest headaches of traditional ABS—warping, odor, and setup complexity—while keeping the strength and durability you need for functional prints.

It's especially recommended if you:

• Print on open or semi-enclosed printers
• Want fewer failed prints and less post-processing
• Value a more pleasant printing experience
