3D printer manufacturer German RepRap has released a number of new 3D printing filaments, expanding its existing materials offering. The new materials include an ESD ABS, an ASA, and a Performance ABS filament. Additionally, the company has released a new color each for its PET-G filament (gray), and its flexible TPU93 filament (black).

Based in Feldkirchen, a district of Munich, German RepRap offers a range of RepRap FDM 3D printers as well as a slew of 3D printing materials. Let’s take a look at the company’s recent additions.

ESD ABS filament

First up is the new ESD ABS filament, which was developed by German RepRap to meet the “intense demand for electrically conductive filament.” Available in black, the new filament is notable for discharging static electricity well, a feature which makes it suitable for 3D printing mounting devices for electronic parts, as well as for “fuel storage and delivery space.”

Because of its static mitigating properties, the ESD ABS filament can also be handy for production applications that involve dust, powder, or even vapors, as it can help to stop particles from being drawn to the plastic printed object. Those interested in ESD ABS can purchase spools of either 0.75 kg or 2.10 kg through German RepRap’s website. The new filament is available in a diameter of 1.75 mm.

ASA filament

German RepRap is marketing its next filament, ASA, as an “outdoor alternative to ABS.” This is largely because the acrylonitrile-styrene-acrylate copolymer has a higher thermal dimensional stability than ABS and possesses good UV and chemical resistance, which ABS does not, making it suitable for outdoor applications.

ASA’s strength, however, is comparable to ABS, so it can be used for printing functional technical parts. The filament is currently available in a natural color and in spools of either 0.75 kg or 2.10 kg (also 1.75 mm diameter).

Performance ABS

The third new material is the Performance ABS filament, which is reportedly similar to standard ABS but features a higher resistance to thermal warping. For makers who have had trouble with warping with regular ABS, the Performance ABS could be a suitable alternative, as it can improve the process of manufacturing “complex, filigree, or large objects”. Performance ABS is available in a natural color and in the same formats as the other two filaments.

Finally, German RepRap has also introduced its existing PET-G filament in gray. The thermoplastic polyester is known for its polarity, as well as its high break strength and thermal dimensional stability up to 176 °F (80 °C).

TPU 93, now available in black, is a thermoplastic polyurethane with good flexibility. This feature, along with its UV, ozone, and abrasion resistance, makes it suitable for producing such parts as cable jackets or automotive interiors. The material’s Shore hardness is 93, and it has displayed an elongation at break of 500%.

German RepRap’s new materials are all available from the company itself as well as its certified resellers. The filaments are compatible with most FDM/FFF 3D printers that use non-proprietary materials.
