Direct digital manufacturing is making fast strides for low-volume applications requiring complex detail, but some significant issues remain. Design engineers require process verification, particularly for high-end parts. For example, the widespread adaption of closed-loop process controls about a dozen years ago provided verification that required process parameters in the injection molding process were being maintained. Direct digital manufacturing systems were originally developed by companies in the rapid prototyping business, where such requirements were not necessary. Parts were simply required for form and fit, and not so much for functional testing. There is often considerable process variation in the new additive fabrication systems being developed for manufacturing directly from digital files. Improvements will come, however, and the new systems are certainly worth a look in several situations, particularly those where there are constant design change orders.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
HP has launched its long-heralded Multi Jet Fusion 3D printing technology for commercial-scale end-production, plus an ecosystem to go with it. The package could change the entire industrial market for making end-products with additive manufacturing. At the very least, it will be game-changing.
Nearly all the products in this latest crop of new adhesives target electronic and other components for consumer electronics and automotive assemblies. Some are alternatives to liquid adhesives, others are liquids that cure faster, and several stick well to multiple substrate materials.
