ABS Filament 3-Pack

3kg of Heat-Resistant, Acetone-Smoothable ABS at $19.67/kg | Mix Any 3 Colors

Three kilograms of ABS. Any three colors you want. Vacuum-sealed for freshness. Free shipping across the USA. At $19.67/kg — 18% off the individual spool price — this is the smart way to stock your most-used ABS colors and never run out mid-project.

⚠️ Before you order: ABS is not a beginner filament. It requires a heated bed (90–110°C), an enclosed printer to prevent warping, and good ventilation — ABS emits fumes during printing that you don't want to breathe in a small room. If you're set up for ABS, this is the best value way to keep three colors in rotation. If you're new to ABS, see the print settings and tips section below before you start.

What Makes ABS the Go-To for Functional Parts

ABS (Acrylonitrile Butadiene Styrene) is the same plastic used in LEGO bricks, car dashboards, and electronics enclosures. It's been the standard for functional 3D printing for decades for three reasons:

• Heat resistance up to ~100°C — PLA softens in a hot car or near a heat source. ABS stays rigid where PLA fails. If your part lives in a warm environment — inside an electronics case, on an engine bay bracket, under direct sunlight — ABS is the right choice.
• Impact toughness — ABS bends before it breaks. PLA is harder but more brittle — it shatters under sudden impact. ABS absorbs the hit and flexes, which is why it's used in protective casings and structural brackets.
• Acetone vapor smoothing — ABS dissolves in acetone. This means you can expose a finished ABS print to acetone vapor for a few minutes and the surface layers literally melt and reflow — eliminating layer lines and producing a glossy, injection-mold-quality finish. No sanding. No filler primer. Just chemistry.

Print Settings for ABS

ABS is less forgiving than PLA or PETG — small changes in temperature and environment have a big effect on results. Use these settings as your starting point and dial in from there.

3 ABS Printing Problems and How to Fix Them

Warping (corners lifting off the bed)
This is the most common ABS problem. Almost always caused by cold air hitting the part during printing. Fix: enclose the printer, raise bed temp to 100–110°C, add a brim in your slicer, and kill the cooling fan completely.

Layer separation (print splitting horizontally)
Layers aren't bonding because the part is cooling too fast between layers. Fix: raise nozzle temp 5–10°C, make sure enclosure is holding heat, and turn off the fan.

Stringing (thin hairs of plastic between parts)
Usually means retraction is too short or temperature is too high. Fix: lower nozzle temp 5°C and increase retraction distance slightly. Run a retraction calibration tower if needed.

Acetone Smoothing — How It Works

This is ABS's secret weapon. Put a finished ABS print inside a sealed container with a small amount of acetone (nail polish remover). The acetone vapor — not the liquid — touches the surface and causes the outer layers to melt just slightly, reflow, and re-solidify smooth. The result is a glossy, professional finish with no visible layer lines. It takes about 5–10 minutes of exposure, then 30–60 minutes of drying. Works on any ABS color.

⚠️ Do this outdoors or in a well-ventilated area. Acetone vapor is flammable — no open flames nearby.

Who Is This 3-Pack For?

• Engineers and makers printing functional parts that will live in warm environments — under the hood, inside electronics, outdoors in summer — where PLA would deform.
• Prototype builders who need smooth surfaces and don't want to spend hours sanding. The acetone vapor method turns a rough printed surface into a presentation-ready finish in under an hour.
• Workshops and production users who go through ABS regularly and want to lock in the savings on their three most-used colors rather than paying per-spool pricing every time.
• Voron, RatRig, and CoreXY builders — ABS is the standard material for Voron structural printed parts precisely because of its heat resistance and toughness. This pack covers a full printer's worth of parts plus spares.
