MakerBot Rot - 650 g - ASA-Filament (3D)

With a heat deflection temperature of 93°C and excellent UV stability, this red ASA filament keeps outdoor parts dimensionally accurate under direct sunlight and high ambient heat. A 650 g Smart Spool feeds MakerBot Method and Sketch printers with ±0.02 mm diameter precision for consistent extrusion and clean layer bonding.

Overview

MakerBot ASA (Acrylonitrile Styrene Acrylate) combines the mechanical strength of ABS with superior weather resistance. The filament is engineered for functional prototypes, automotive trim, electrical housings, and any part exposed to moisture, UV radiation, or temperature swings. Its low shrinkage reduces warping on open-frame printers, while the matte red finish hides minor layer lines for a professional look straight off the build plate.

What stands out

• Excellent UV and weather resistance for long-term outdoor use
• High impact strength and good chemical resistance
• Low odor during printing compared to standard ABS
• Smart Spool with RFID automatically loads material settings on compatible MakerBot printers
• Low shrinkage and warp for easier printing of large, flat parts
