Question 1

Is eSUN ABS+ easier to print than regular ABS, and do I still need an enclosure?

Accepted Answer

While eSUN ABS+ is formulated for better layer adhesion and reduced warping *compared to some standard ABS*, it still retains core ABS properties. For small prints, a heated bed and proper bed adhesion (like a glue stick) may suffice. However, for successful medium to large prints, a heated enclosure is highly recommended by most experienced users to consistently prevent warping and layer splitting. It's an upgrade, but not a magic bullet for beginners.

Question 2

I've heard about spool tangling issues. Is this common?

Accepted Answer

While many users report flawless spools, a notable number of reviews across platforms mention occasional spool winding problems that can lead to tangles and breaks. This appears to be a quality control inconsistency. We recommend inspecting the spool upon arrival and keeping slight tension on the filament during the first layers. If you receive a tangled spool, please contact customer support for assistance.

Question 3

How does this filament compare to PLA+ or PETG? Who is it best for?

Accepted Answer

eSUN ABS+ is best for functional, durable parts that need higher heat resistance (e.g., car interior parts, tool handles, mechanical gears). It's stronger and more heat-resistant than PLA+ but is more challenging to print, requiring higher temperatures and ventilation due to fumes. PETG is often seen as a middle-ground—strong, moderately heat-resistant, and easier to print with less odor. Choose ABS+ if you need its specific material properties and have the right printer setup.

Question 4

It smells a lot during printing. Is this normal and safe?

Accepted Answer

Yes, printing with any ABS filament, including ABS+, produces a noticeable and strong odor due to the styrene content. It is crucial to print in a very well-ventilated area or use a filtration system. We do not recommend printing in living spaces without proper ventilation. The smell is a typical characteristic of the material, not a defect in this specific brand.

Question 5

How should I store this filament to keep it printing well?

Accepted Answer

ABS+ is hygroscopic, meaning it absorbs moisture from the air, which can lead to bubbling, poor layer adhesion, and a brittle texture. Many Reddit users emphasize storing it in a sealed container with desiccant when not in use. If your prints start showing moisture issues (popping/cracking sounds from the nozzle), drying the spool in a filament dryer or a low-temperature oven before use is highly recommended for best results.
