INNOVATION | 3D PRINTING
Above: MakerBot has added PC-ABS and PC-ABS FR speciality materials for functional prototyping and end-use applications on Method X
advanced engineering materials that are difficult to print successfully on a desktop 3D printer. With a modified hot end, the new MakerBot Labs BS extruder gives users advanced customisation options for new materials, including interchange- able nozzle assemblies and expanded print settings in MakerBot’s print preparation software, MakerBot Print. The Labs extruder can reach up to 300°C, and includes sensors that track tempera- ture, materials and extruder jams. MakerBot says that it is actively working with its partners to qualify specific materials for the Method platform. Recommended materials for the MakerBot Labs Experimental Extruder for Method include Poly- maker PolyMax PC, which offers good toughness, strength and heat resistance. This filament opens new applications in the automotive, railway and aerospace industries. Jabil PETg ESD from Jabil Engineered Materials is an easy processing, electrostatic dissipative product for printing sensitive electronic parts that could be damaged by electrostatic discharge. Jabil TPE SEBS 1300
95A is a flexible material with a 95A durometer that bends, flexes and stretches, and has demonstrated success in printing complex geometries. Unlike other elastomers, SEBS 95A is not sensitive to mois- ture and does not require drying. In addition, Kimya ABS Carbon is an ABS composite material with 30% chopped carbon fibre for improved stiffness and compression strength, as well as lower weight than regular ABS. Kimya PETG Carbon is a PETG reinforced with carbon fibres for improved stiffness and increased tensile strength over regular PETG. Mitsubishi Chemical offers Durabio, an engineering, bio-based resin. It combines PMMA’s transparency with a higher chemical and scratch resistance compared to polycarbonate. MakerBot has also added PC-ABS and PC-ABS FR speciality materials for functional prototyping and end-use applications on Method X, which is a more suitable system for ABS materials. PC-ABS has high heat resistant properties and tensile strength, which make it optimal for use across automotive, rail, and electronics industries. PC-ABS FR is a flame-retardant material that meets the UL-94 V0 standard. The addition of polycarbonate to ABS delivers higher impact strength and heat resistance than the standard ABS material, and is used frequently in injection moulding. PC-ABS prints more successfully with an en- closed heated chamber, consistently delivering high-quality parts. Parts printed on a desktop 3D printer with only a heated build plate are suscepti- ble to temperature variations that can cause part deformation and lower part strength. MakerBot increased Method X’s maximum enclosed chamber temperature at the build plane from 100°C up to 110°C to ensure superior part accuracy and interlayer adhesion. “With its excellent thermal and mechanical
3D Systems’ software aids mouldmakers
Two leading German industrial tool makers are using Cimatron integrated CAD/CAM software by 3D Systems to overcome production challenges faster and more successfully. Cimatron software is a dedicated design and manufacturing solution for tooling that is drawing renewed interest because of its ability to design and deliver moulds faster, maintain data integrity between design and manufacturing, and its electrode design and EDM programming application.

Harting Applied Technologies develops, designs and produces injection moulds, die casting moulds and other products. Following a phased implementation of Cimatron, all application areas at Harting are now served by this dedicated, integrated CAD/CAM software. This has helped the company to enhance data integra- tion through the entire mould-making process, resulting in improved production quality and efficiency with decreased lead times, reduced scrap
and improved tool quality. VMR supports its customers with design and NC programming, production and assembly, as well as providing customised mould design and optimisation. The company uses Cimatron integrated CAD/CAM software to design and manufacture prototypes and short manufacturing runs efficiently and cost-effectively. The use of this software has helped the company reduce electrode design and manufacturing time by 70%.
