German RepRap has responded to market demand by adding three new materials to its portfolio as well as two new color variations of filaments that are already part of the portfolio. The new filaments ASA, Performance ABS, and ESD ABS are available immediately. In addition, the PET-G filament is now available in gray, and the flexible TPU93 filament is now available in black.
Due to intense demand for electrically conductive filament, German RepRap now offers ESD ABS. Objects printed from ESD ABS are suitable for applications where electrostatic charges can cause damage. Since ESD ABS discharges static electricity very well, it can be used to avoid explosions or reduced performance. This property is for fabricating mounting devices for electronic components and for the fuel storage and delivery space. For production applications that involve powder, dust, or vapor, ESD ABS can also prevent particles from being attracted by the plastic objects. German RepRap ESD ABS filament is available in black as a 0.75 kg spool with a diameter of 1.75 mm as well as a 2.10 kg spool with a diameter of 1.75 mm.
The ASA filament is an acrylonitrile-styrene-acrylate copolymer, and is used as an “outdoor” alternative to ABS. ASA features higher thermal dimensional stability than ABS and is UV and chemical-resistant, unlike ABS. Its high impact strength is similar to ABS, and due to its technical properties, it is suitable for technical (functional) components. German RepRap ASA filament is available in natural color as a 0.75 kg spool with a diameter of 1.75 mm as well as a 2.10 kg spool with a diameter of 1.75 mm.
The Performance ABS features are comparable to the mechanical/thermal properties already available with the Standard ABS, but with considerably higher resistance to thermal warping. This simplifies the process of printing complex, filigree, or large objects from ABS. Performance ABS filament is available in natural color as a 0.75 kg spool with a diameter of 1.75 mm as well as a 2.10 kg spool with a diameter of 1.75 mm.
TPU 93 is a thermoplastic polyurethane, which has common applications for manufacturing cable jackets and for providing a comfortable feel to surfaces in automotive interiors. The material is soft, resistant to UV and ozone, as well as weather and abrasion-resistant. Filament TPU 93 offers extremely high flexibility: In measurements in accordance with DIN EN ISO 527 the material reached an elongation at break of 500%, and the Shore hardness is 93. The black TPU filament is now also available as a 0.75 kg spool with a diameter of 1.75 mm as well as a 2.10 kg spool with a diameter of 1.75 mm.
PET-G features optimal mechanical properties and excellent thermal plasticity. PET-G is a type of thermoplastic polyester, produced by polycondensation, and it has a variety of uses. PET-G is polar, which causes strong intermolecular forces. In addition, the molecule is linear, without any cross-linking. Both are prerequisites for partially crystalline areas and fibers. These attributes are responsible for the high breaking strength and a thermal dimensional stability up to a temperature of about 176 °F (80 °C). The material is currently available in gray, as a 0.75 kg spool with a diameter of 1.75 mm and as a 2.10 kg spool with a diameter of 1.75 mm.
