SUNLU Easy ABS Filament: The best solution for warping in traditional 3D printing ABS

As a 3D printing enthusiast, you are likely familiar with the typical problems associated with traditional ABS filament: severe warping, lifting corners, layer cracking, intense odor, and the need for a fully enclosed printer with a high chamber temperature.

Traditional ABS offers excellent strength, heat resistance, and durability – ideal for functional parts like housings, brackets, or car parts. However, due to high shrinkage and temperature sensitivity, it is often difficult to print, especially on open printers or in cooler rooms.

This is where SUNLU Easy ABS filament (also known as E-ABS) comes in. This advanced ABS variant retains the key advantages of ABS while significantly reducing its biggest drawbacks: less warping, lower printing temperatures, significantly reduced odor, and better adhesion to the print bed. It is suitable for both beginners and experienced makers.

In this article, we explain why traditional ABS warps so much, how SUNLU Easy ABS solves these problems, which print settings are recommended, what users are actually reporting, and how you can achieve even better results with practical solutions.

Why does traditional ABS filament warp so much?

Warping occurs when the printed part cools unevenly, creating internal stresses that cause corners and edges to lift off the print bed. Traditional ABS is particularly susceptible to this because of:

• High thermal shrinkage (approx. 0.8% or more)
• High sensitivity to drafts and temperature fluctuations
• Poor layer adhesion when cooling is too strong
• High required bed temperature (90–110 °C) and nozzle temperature (240–280 °C)

Common complaints with standard ABS:

• Lifting corners on large flat parts
• Cracks between layers
• Strong "plastic smell" during printing
• Need for an enclosure, glue stick, hairspray, or wide brims/rafts

These problems lead to many failed prints, material waste, and frustration – especially without professional equipment.

How SUNLU Easy ABS filament solves warping problems

SUNLU developed Easy ABS as an "easier" evolution of classic ABS. Special modifiers improve material flow, reduce shrinkage, and increase layer adhesion – without sacrificing too much mechanical robustness.

Key advantages of SUNLU Easy ABS compared to traditional ABS:

• Very low warping and shrinkage – often prints successfully on open printers even with larger parts
• Lower printing temperatures – nozzle 225–255 °C, bed only 60–70 °C (more energy-efficient and easier on the hardware)
• Significantly reduced odor – more pleasant for home and office use
• Better bed adhesion – works well on PEI plates, often without additional glue
• Improved layer adhesion – fewer cracks and delamination
• Wide printer compatibility – well-suited for Bambu Lab A1, Prusa, and other open or partially enclosed printers

Its heat resistance is slightly lower than pure ABS (closer to high-quality PETG) but is perfectly sufficient for most functional applications.

Suitable applications: Electronic housings, brackets, automotive interior parts, tools, fixtures, and protective covers.

Recommended print settings for SUNLU Easy ABS

Good results start with the right settings. Here are proven starting values based on SUNLU recommendations and user experiences:

• Nozzle temperature: 225–255 °C (start at 240 °C, optimize with a temperature tower)
• Bed temperature: 60–70 °C
• Print speed: 50–200 mm/s (slower for first layers)
• Cooling: Fans can be turned on (unlike standard ABS, usually 0–10%)
• Layer height: 0.2 mm standard, 0.12–0.28 mm possible
• Enclosure: Not strictly necessary for most parts, but recommended for very large or tall objects (>10 cm) (a simple cardboard box or partial enclosure is often sufficient)

Additional tips for optimal results:

• Dry the filament before printing (if moisture is absorbed: 50 °C for 4–6 hours)
• Use a wide brim or raft for very large parts
• Avoid drafts (close windows, keep away from air conditioning)
• Clean the print bed thoroughly (isopropyl alcohol)

Many users print SUNLU Easy ABS successfully on Bambu Lab printers using adjusted ABS profiles.

Real user feedback on SUNLU Easy ABS

Community reviews are largely positive:

• "Warping and cracking reduced by 99% – even runs on an open printer without issues."
• "Finally ABS without the constant struggle with the enclosure."
• "The low odor makes long prints much more pleasant."

Constructive criticism:

• Slightly lower heat resistance than pure ABS (might not be optimal for extremely hot applications)
• Occasional surface issues or slight clogs if temperature settings are inaccurate
• Mechanical properties (e.g., impact strength) slightly below classic ABS, but still significantly better than PETG

In summary, SUNLU Easy ABS makes ABS truly accessible to many makers – without the need for expensive, high-performance equipment.

Practical solutions against ABS warping (even with Easy ABS)

Even with an easier filament like SUNLU Easy ABS, the following measures can help if warping still occurs:

1. Optimize the first layer: Level the print bed perfectly. Keep the PEI plate clean. Use a wide brim (8–12 mm) or raft for large parts. If necessary, use a light glue stick or hairspray.
2. Minimize temperature differences: Avoid drafts. For tall parts, use a simple enclosure or activate a draft shield in your slicer.
3. Adjust cooling and speed: Print the first layers slower. Balance the fan speed. Increase minimum layer time.
4. Dry and store filament: ABS variants absorb moisture. Dry before every print and store with desiccant.
5. Consider part design: Avoid sharp 90° corners on large areas (add chamfers or fillets). Align parts to minimize long, flat areas.
6. Optimize slicer settings: Activate "Elephant's Foot Compensation." Test bed and nozzle temperatures in 5 °C increments.

With these steps, most warping problems can be solved – even if you occasionally revert to classic ABS for maximum heat resistance.

Conclusion: Is SUNLU Easy ABS worth it?

For most 3D printing users, SUNLU Easy ABS filament is a smart evolution that significantly reduces the biggest weaknesses of traditional ABS – warping, odor, and complicated print preparation – while maintaining sufficient strength and durability.

Especially recommended if you:

• Work on open or partially enclosed printers
• Want fewer failed prints and less post-processing
• Prefer a more pleasant printing process
