Dynalabs ABS Filament 1.75mm 1kg

Dynalabs ABS Filament 1.75mm — Heat-Resistant, Smoothable, Industrial-Grade

ABS (Acrylonitrile Butadiene Styrene) is the original engineering thermoplastic of desktop 3D printing — and for good reason. It handles heat up to 100°C, absorbs impacts without shattering, and can be vapor-smoothed with acetone to achieve a glossy, injection-mold-like finish that no other common filament can match. The Dynalabs ABS at $14.99 per kilogram gives you this industrial performance in 10 colors.

Available in: Black, White, Blue, Red, Green, Yellow, Silver Grey, Natural, Fuchsia, and Fluo Orange. The standard palette covers most functional and visual needs for engineering and prototype work.

Key Specifications

Why Choose ABS?

ABS excels where PLA and PETG fall short. It handles sustained heat (dashboards, electronics enclosures near heat sources), it can be chemically welded with acetone (join multiple parts seamlessly), and acetone vapor smoothing produces a glossy, professional surface finish that eliminates visible layer lines entirely. If your end product needs to look like an injection-molded part, ABS with vapor smoothing is the most cost-effective path.

Recommended Print Settings

ABS requires an enclosed printer to prevent warping from temperature fluctuations. Print at 240–250°C nozzle and 100–110°C bed. First layer speed: 20mm/s. Use a brim (8–10mm) for bed adhesion on parts wider than 50mm. ABS produces fumes during printing — always use an enclosure with filtration or print in a well-ventilated space. ABS juice (ABS scraps dissolved in acetone) applied to the bed is the most reliable adhesion method.

Acetone Vapor Smoothing — Step by Step

Place your printed part on a raised platform inside a sealed container. Add a small amount of acetone to paper towels lining the container walls (never in direct contact with the part). Seal and wait 30–60 minutes. The acetone vapor melts the surface layer of ABS, filling in layer lines and creating a smooth, glossy finish. Remove and let dry for 2–4 hours. This technique is what separates amateur-looking prints from professional results.

Pro Tips

ABS shrinks more than PLA during cooling (~0.7% vs 0.3%). For dimensionally critical parts, print a test piece and measure shrinkage, then scale your model accordingly. The Natural (unpigmented) variant is the strongest — pigments slightly reduce tensile strength. For maximum strength, print with 4+ walls, 40%+ infill, and 3 top/bottom layers.

Best Applications

Automotive parts, electronics enclosures, power tool housings, RC car components, functional prototypes for injection molding validation, lego-compatible bricks, acetone-smoothed display models, and any part requiring heat resistance combined with toughness.
