Ultimaker has also introduced two additional
products for its 3D printing systems. These include Tough PLA, a technical PLA filament optimised for printing models at larger sizes such as functional prototyping, tooling and manufacturing aids, with no delamination or warping. With an impact strength similar to, and higher stiffness compared to, Ultimaker ABS, Tough PLA is less brittle than regular PLA and gives a more matte surface finish quality. In addition, the Ultimaker App allows users to stay updated on the print’s progress from a phone or tablet. The free App notifies users when a print job is ready or when a printer needs special attention or maintenance. Stratasys has introduced the Fortus 380CF

workflow. It has an optimised touch screen for better user experience and has a 330×240×300 mm build volume for printing larger objects. There is dual extrusion and an improved feeder system with a filament flow sensor that auto pauses and resumes when materials run out, leaving print quality untouched. The enhanced bed levelling ensures a perfect first layer and continuously compensates the print bed while printing, which allows unattended use. The company says that the Ultimaker S5 unlocks new applications and can print with a wider range of materials, from PLA to advanced engineering plastics such as PA and PC. The Ultimaker S5 includes a closed front system and an anodised build-plate.
Production 3D printer for its high-performance Nylon 12 carbon fibre thermoplastic material. Containing 35% chopped carbon fibre, the company says that Nylon 12CF is strong enough to replace metal, allowing designers to develop more practical and functional design. Visual First, a Dutch service bureau, is using FDM Nylon 12CF to replace metal machine parts for its customers. This is significantly reducing machine downtime on the factory floor, ensuring production line continuity. In fact, for its customer, The Chocolate Factory, the replacement time of broken machine parts has been reduced from one month to just one week, while costs have reduced by 60% since using Stratasys additive manufacturing instead of traditional subtractive metal-based processes.
� Arburg goes larger with Freeformer
Arburg is launching a larger Freeform- er, the 300-3X, at Formnext to be held from 13-16 November 2018 in Frankfurt am Main, Germany. The company says that the new large machine can process three compo- nents using the Arburg Plastic Free- forming (APF) process, enabling the industrial additive manufacturing of complex functional parts in resilient hard/soft combinations with support structure as a world first. “For many years, users have appreci-
ated the benefits of our Freeformer 200-3X and the possibilities that the system and Arburg Plastic Freeforming have to offer,” says Lukas Pawelczyk, who has been responsible for Free- former sales worldwide since July
50 INJECTION WORLD | October 2018
2018. “As a revolutionary next step, we’re celebrating the world premiere of the Freeformer 300-3X at Formnext 2018, which will expand the Arburg product range and open up new fields of application. For the first time worldwide, complex and resilient functional parts can be produced from three components in hard/soft combi- nation with support structure using this machine for industrial additive manu- facturing – that’s unique in the industry.” With the Freeformer 300-3X, the
designation 300 stands for the available part carrier surface area in square centimetres. This is just under 50% larger than on the Freeformer 200-3X. The build chamber now offers space for larger small-volume batches
and 50% wider parts with dimensions of up to 234 × 134 × 200 mm. ‘3X’ stands for the moving axes of the part carrier in the x, y and z directions. A two-part build chamber door is a
new feature on the Freeformer 300-3X. This enables the feed hoppers, for example, to be refilled during ongoing operation by opening the top half of the door. The heated build chamber now only needs to be opened for inserting the part platform and removing the finished parts. Automatic opening and closing of the build chamber door, as well as optional interfaces, also enable automation of the additive manufacturing process and integration of the Freeformer in complete production lines.
