Buying ABS 3D Filament Rolls: Is Leroy Merlin a Good Choice?

Introduction

At DunaTech, we tested ABS filaments from various brands, including some available at Leroy Merlin, to determine if they’re truly worth it. After comparing five different rolls on our Anycubic Kobra printer, we discovered several key differences in quality, printability, and mechanical strength.

What is ABS Filament?

ABS filament (Acrylonitrile Butadiene Styrene) is one of the most commonly used materials in FDM 3D printing due to its impact resistance and ability to withstand extreme conditions. However, it requires higher printing temperatures and is more difficult to handle compared to PLA.

**Key Features:**
– Printing temperature: between 230°C and 260°C.
– Requires heated bed: >90°C.
– Produces emissions (a well-ventilated area is recommended).
– More impact and heat-resistant than PLA.

Where to Buy ABS Filament?

In my experience, Leroy Merlin offers a limited selection of ABS filaments at prices that are not always competitive. The available rolls tend to be generic, and after testing one in our workshop, we noticed inconsistency in diameter and bed adhesion issues.

On the other hand, we found better options on AliExpress, where brands like eSUN and SUNLU offer ABS rolls with consistent diameters and fewer warping problems. Additionally, these rolls are often available at lower prices with coupons.

Tests at DunaTech

To evaluate the quality of ABS filaments, we used an Anycubic Kobra printer and conducted test prints with mechanical parts like gears. Here are the results:

**Generic Leroy Merlin Filament (1 kg roll):**
– **Pros**: Physically accessible, no shipping costs.
– **Cons**: Inconsistent diameter (variations of ±0.05 mm), bed adhesion issues, frequent warping.

**eSUN ABS+ Filament (AliExpress):**
– **Pros**: Consistent diameter (±0.02 mm), excellent adhesion with a heated bed at 100°C, fewer emissions.
– **Cons**: Requires proper ventilation and pre-drying if the roll is not well-stored.

Common Problems and Solutions

**Excessive Warping**: If ABS filament detaches from the heated bed, ensure you’re using an appropriate bed temperature (100°C) and apply an adhesive layer like hair spray or specialized glue.

**Inconsistent Diameter**: Purchase trusted brands with quality certification. In my experience, generic rolls tend to cause extruder clogs.

**Harmful Emissions**: Use a printer in a well-ventilated area or with an active carbon filter. This is especially critical if printing in enclosed spaces.

FAQ

Is ABS better than PLA?

It depends on the application. While PLA is ideal for decorative pieces, ABS is better for functional parts requiring impact or heat resistance.

Can ABS be used without a heated bed?

It is not recommended. ABS requires a heated bed to prevent warping and ensure proper adhesion.

Which ABS brands are the best?

After testing several brands, I recommend eSUN and SUNLU for their consistent quality and reliable performance.

Conclusion

Although Leroy Merlin may be a quick option for buying ABS filament, their rolls do not offer the same quality as specialized brands available on AliExpress, such as eSUN. If you’re looking for reliable results and less hassle, investing in a higher-quality roll is the best decision.
