Do I need an enclosure to print ABS?

Effectively, yes. ABS shrinks as it cools, and on an open printer that shows up as warped corners, cracked layer lines, and parts that lift off the bed mid-print. An enclosure traps heat to keep the whole part cooling evenly, which is how ABS reaches its real strength. The rise of affordable enclosed CoreXY printers is the main reason ABS is worth buying again in 2026 — without a chamber, PETG or PLA will frustrate you far less.

Is ABS dangerous to print?

ABS emits styrene and a noticeable plastic odor while printing, so it wants real ventilation — a filtered enclosure, an open window, or a vented space, not a closed bedroom. The fumes aren't acutely toxic at hobby volumes, but you shouldn't breathe them all day. Lower-odor ABS+ blends cut the smell down but don't eliminate the need for airflow.

What's the difference between ABS and ABS+?

Classic ABS is the original engineering plastic: strongest and most heat-resistant, but the fussiest to print and the most prone to warping. ABS+ blends (like eSUN ABS+) add impact modifiers and tackifiers for better layer adhesion, less warping, and lower odor — easier to live with, at a small cost in peak heat resistance. If you're new to ABS, start with an ABS+ or a low-warp engineered ABS, not the classic stuff.

How do I stop ABS from warping?

Print inside an enclosure, use a heated bed at 90–110°C, and add adhesion help — a glue-stick layer on PEI or glass, plus a wide brim. Keep the part cooling slowly (low or no part-cooling fan for the first layers), and don't open the enclosure mid-print. Low-warp engineered ABS like FormFutura TitanX is more forgiving, but process still matters more than brand.

Does ABS need to be dried?

Less aggressively than PETG or nylon, but yes when it's been open a while. Wet ABS prints with a rough, hazy surface, more popping, and weaker layers. Dry it around 65–80°C for several hours if you hear crackling or see steam in the extrusion, and store it sealed with desiccant. See our filament drying guide for the full method.

Best ABS Filament in 2026: Strong, Heat-Resistant Picks

Updated 2026-06-19 · by Jay

The best ABS filament is the one that's well-made, in stock, and fairly priced today — and most "best ABS" lists can't tell you the last two, because they were written once and never updated. The recommendations below are pulled from FilaScope's live database: prices re-checked daily, dead listings dropped automatically, so you're never clicking through to a sold-out spool or a year-old number.

One thing up front, because it decides whether you should buy ABS at all: ABS needs an enclosure. It's a strong, heat-resistant engineering plastic — rigid to roughly 90–100°C, sandable, and acetone-smoothable — but it shrinks as it cools, and on an open-frame printer that means warped corners and cracked layers. If your printer is enclosed, ABS is one of the best-value functional materials you can buy. If it's open-frame, read PETG vs ABS first.

The short answer

New to ABS, or want the least drama? Start with an ABS+ blend (eSUN ABS+) or a low-warp engineered ABS (FormFutura TitanX). Both forgive imperfect setups better than classic ABS.
Printing fast on an enclosed CoreXY? Reach for a high-flow ABS (Creality Hyper ABS, eSUN High-Speed ABS+) that keeps up with the volume.
Want clean tolerances and recycled packaging? Polymaker PolyLite ABS holds ±0.03mm and ships on a recycled cardboard spool.
Want colors and a community-proven baseline? Hatchbox ABS has been the hobby default for years.

The picks

eSUN ABS+ — the easiest place to start. eSUN's ABS+ adds impact modifiers and tackifiers to plain ABS for better layer bonding, less warping, and lower odor — the most forgiving entry point if you've never printed ABS. Trade-off: a true ABS+ blend gives up a little peak heat resistance versus pure ABS, so for parts right next to a heat source you may want classic ABS or ASA. And "low-odor" means less, not none — keep the ventilation. eSUN ABS+ on Amazon

eSUN High-Speed ABS+ — ABS+ that keeps up with a fast printer. A higher-flow version of the above, formulated (eSUN's claim) for the 50–300mm/s range with good layer adhesion and low warping. If you bought an enclosed CoreXY to print fast, classic ABS can bottleneck the flow rate; this is the blend that fixes that. Trade-off: like all high-flow materials, it rewards a well-tuned machine — push past what your hot end can melt and you'll under-extrude regardless of the spool. eSUN High-Speed ABS+ on Amazon

Creality Hyper ABS — the high-flow option for speed-first setups. Creality's Hyper line is built around volumetric flow: a modified resin tuned to melt and lay down quickly so it keeps pace with high-speed printing (Creality rates it up to 300–350mm/s, ±0.02mm — manufacturer figures). A sensible match for a Creality K-series or any fast enclosed machine. Trade-off: those headline speeds assume an enclosure and a capable hot end. It still warps without a chamber like any ABS, and the flow advantage only matters once you're actually printing fast. Creality Hyper ABS on Amazon

Polymaker PolyLite ABS — clean tolerances, tidy packaging. Polymaker's bulk-polymerized ABS holds a tight ±0.03mm diameter and ships vacuum-sealed with desiccant on a recycled cardboard spool — a small thing that adds up if you care about waste. A solid, predictable classic ABS for functional parts. Trade-off: this is real ABS, not an easy-mode blend, so it still wants an enclosure, a hot bed, and adhesion help. You're paying mid-tier for consistency, not forgiveness. Polymaker PolyLite ABS on Amazon

Hatchbox ABS — the proven baseline, in every color. A hobby default for years: wide color selection, easy availability, and a long enough track record that any problem you hit has been solved on a forum already. The safe pick when you want a no-surprises classic ABS in a specific color. Trade-off: classic ABS with classic ABS habits — it warps without an enclosure and isn't tuned for high-speed flow. Dependable, not fancy. Hatchbox ABS on Amazon

FormFutura TitanX — the low-warp premium pick. TitanX is an engineered ABS with added impact modifiers, marketed as low-to-zero warp with strong interlayer adhesion and higher impact resistance than regular ABS (FormFutura claims >65%). For large parts where warping is the whole problem, the premium can be worth it. Trade-off: it's the priciest spool here, and "low warp" is not "no warp" outside ideal conditions — an enclosure and good bed prep still earn their keep. Buy it when the part is big, the deadline is real, and a failed print costs more than the filament. FormFutura TitanX on Amazon

Heads up: these are research-based recommendations from real, current, well-regarded ABS lines — not a hands-on lab test. Any speed or strength figures above are manufacturer claims, labeled as such. Prices and the exact "best" spool today are carried by the live block below, not by this text.

What to know before you buy

Buying good ABS is half the job. The other half is setup, because ABS punishes a casual approach more than any common filament:

Enclosure, not optional. ABS shrinks as it cools. Trap the heat with an enclosure so the whole part cools evenly — otherwise corners lift, layers split, and the print fails. It's the single biggest predictor of ABS success.
Ventilation, every time. ABS releases styrene and a strong odor. Print in a ventilated space or a filtered enclosure, not a sealed room you sit in. Low-odor ABS+ helps but doesn't replace airflow.
Bed adhesion is a project. Run the bed at 90–110°C, lay down a glue-stick release layer on PEI or glass, and add a wide brim to anchor the corners. Pull prints only after the bed has cooled.
Dry it when it's been open. ABS is less thirsty than PETG or nylon, but a spool that's sat out for weeks prints hazy and weak. Dry around 65–80°C for a few hours if you see steam or hear popping. Our filament drying guide has the method.
ABS vs ABS+ — pick deliberately. Classic ABS (Polymaker, Hatchbox) is strongest and most heat-resistant but warps the most. ABS+ blends (eSUN ABS+) trade a little peak performance for noticeably easier printing. New to the material? Start with the blend.

ABS vs the alternatives

If you're not yet sure ABS is the right material — just which ABS to buy — the comparisons go deeper than this guide:

PETG vs ABS — the honest question for most people: do you actually need ABS's heat resistance, or will PETG do the job without an enclosure?
ASA vs ABS — if the part lives outdoors, ASA is ABS's UV-stable sibling and almost always the better call.
Best filaments for functional parts — where ABS fits against PETG, ASA, and nylon on the strength-vs-hassle spectrum.
