Strong, flexible and heat resistant ABS filament for engineering applications.

The BASF Ultrafuse line of filaments for FFF 3D printing not only contains metallic filaments but also standard, engineering, flexible, reinforced, high temperature and support filaments. Among the standard materials is the Ultrafuse ABS filament available in 9 colors in spools of 750 g and both 1.75 mm and 2.85 mm diameters. The Ultrafuse ABS filament is manufactured on state-of-the-art computer-controlled machinery, which ensures filament consistency between colors and batches, as well as reliable thermomechanical properties. The Ultrafuse ABS filament is compatible with breakaway supports such as the Ultrafuse HiPS support material.

Part 3d printed with the BASF ABS

ABS (Acrylonitrile Butadiene Styrene) is a common amorphous thermoplastic polymer and the second most used material in 3D printing, right after PLA. From these two materials, ABS is the go to polymer for engineers and professional applications thanks to its good mechanical resistance (excellent impact strength), relative flexibility, fairly light weight, good thermal and chemical resistance and affordability

Another valuable ABS property is that it can be machined, smoothed with acetone and painted with acrylic and enamel based paints, which makes it especially popular in the automotive industry for the manufacturing of prototypes and functional parts such as instrument panels, door liners, handles or pillar trims.

High speed printing

Furthermore, the ABS Ultrafuse filament is compatible with high printing speeds. In order to create complex structures with this material and a support material, the Xioneer VXL 90 soluble support material or the VXL 111 soluble support material are recommended by the manufacturer. These support materials can be extruded at high speeds as well, which means a smooth and efficient 3D printing. The water solubility of VXL 90/111 makes the post-processing more precise and fast. In the Downloads section a table of compatibilities between the BASF Ultrafuse and Xioneer support filaments can be consulted.

Like all 3D printing filaments, the Ultrafuse ABS should be stored properly in order to be protected from absorbing moisture. Humidity is the worst enemy of filaments and can lead to extrusion problems and poor print quality. The Ultrafuse ABS filament should be stored in a vacuum sealed bag with a filament drying capsule, in an intelligent filament container before and after printing, and in a filament drying device during printing. 

The BASF Ultrafuse ABS filament should be extruded at a temperature of 230-255 ºC and a speed of 30-70 mm/s. A 3D printer with a heated bed is required to 3D print with the Ultrafuse ABS filament, and the temperature of the bed should be set to a minimum of 90 ºC (max 120 ºC). 

ABS is a material sensitive to drafts and can warp if printed in uncontrolled environments. It is recommended, although not necessary, to print the Ultrafuse ABS in a closed 3D printer, especially with medium and large parts. To further reduce the chance of warping, the layer fan can be used. Printing ABS on the BuildTak surface or using Kapton Tape, bed adhesion sprays such as DimaFix or 3DLac, or adhesive glue, for example 3DLac Stick or Magigoo, can also significantly improve adhesion and reduce warping with the Ultrafuse ABS.
