PRODUCT DEVELOPMENT | TECHNOLOGY
Other customers harnessing the technology to produce 3D printed composite tools include McLaren Racing. Stratasys has also developed a range of printers
for prototyping solutions, including the F123 Series of 3D printers. From concept verification to design validation and functional performance, the com- pany says that the F123 is aimed at designers and workgroups as an easy-to-use solution adept at every prototyping stage. In addition, the full colour, multi-material 3D printer Stratasys J750 can eliminate several assembly and post-processing steps during the product design. This enables designers to make significant time-savings during prototyping and allow rapid decision-making to accelerate product development. This is exempli- fied by Audi, which produced an ultra-realistic rear brake light housing 50% faster with the J750 compared to its previous prototyping methods. 3D Systems has developed a number of solutions for helping manufacturers move from prototyping to production and achieve competitive advantages. One such platform designed for production is Figure 4 Production and Figure 4 Standalone. The company says that the Figure 4 Production offers part print speeds of up to 65 mm/h, with prototyping speeds of up to 100 mm/h. The Figure 4 platform delivers part accuracy and repeatability, with Six Sigma repeatability across all materials. The system offers a combination of speed and accuracy complemented by a light-
based UV curing process that takes minutes compared with hours for heat-based curing processes. Figure 4 enables high-speed digital moulding, a
process that complements traditional production methods, providing manufacturers with the accuracy, reliability, repeatability and uptime of traditional moulding, producing parts without the costs and more time-consuming aspects of tooling. Digital moulding is completely scalable, and with the high surface quality available on Figure 4, excels at fine part texturing. In comparison to conventional manufacturing, part texturing is essentially free and applicable to any surface no matter the shape.
In addition to supporting long- and short-run The EOS P 810
The Freeformer 300-3X expands the application range of Arburg Plastic Freeforming (APF). With its three discharge units, complex functional parts can be additively manufactured as resilient hard/soft combinations
With the two Freeformers 200-3X and 300-3X,
Arburg will in future cover a significantly broader range of applications. At Formnext 2018 there will be three exhibits and a host of parts, including a selection of two and three-component items, on display. The exhibited functional parts include a two-component gripper as a hard/soft combination, cable clips made from PP, transparent test discs made from PMMA and bellows made from medical TPE-S. Users can process their own original materials and optimise droplet size as well as process control with the open Freeformer system. The Arburg material database documents qualified standard granulates such as ABS (Terluran GP 35), PA10 (Grilamid TR XE 4010), PC (Makrolon 2805), TPE-U (Elastollan C78 A15) and PP (Braskem CP 393). Further examples include special plastics for specific applications such as medical PLLA (Purasorb PL18, Resomer LR 708) and a PC (Lexan 940) approved for aerospace use. The range of qualified materials is continuously being expanded, says the company.
