TECH WATCH A Separating Way to Print in 3D The 3D printing industry usually touts the speed and accuracy of its devices as they move a digital design to its seemingly flawless physical representation in a matter of moments. Details like the sometimes tedious steps required to refine the printed object are typically left out of the marketing materials. Rize Inc. ( rize3d.com ) says among the key attributes of its new Rize One 3D printer is the fact that there's virtually no post-production processing of parts. The company began shipping the desktop-compatible printer, which makes use of an Augmented Polymer Deposition (APD), a patented technology that uses its Rizium One, an engineering and medical-grade thermoplastic filament. The printer distributes the appropriately named Release One ink in between the part and the support structure so it can be removed manually, and according to Rize, without the need for sanding or filing. Rizium One has other nontraditional qualities for a 3D printer, the firm says. The material is isotropic, which means it is uniform in strength along the X, Y and Z axes. It also means prototypes are suitable for the stresses of functional testing. Bosch's Dive into Wafer Tech This desktop machine, the Rize One, is said to produce parts that require very little in the way of post-processing. Bosch ( bosch.com ) likes to boast that its application-specific integrated circuits (ASICs) have been used in vehicles since 1970. Some 36 years later, each vehicle produced around the world has, on average, at least nine Bosch chips on board, according to the company. The hope in Dresden these days is that's only for starters, as Bosch plans to build a wafer fab there to meet the demand of the wireless sensor market (such as for the tire trend monitor) . Construction is set for completion in 2019 with production pegged for 2021 at the estimated 1-billion euro facility, which will focus on 12-inch wafer technology. The plant will employ 700 in a town that's come to be known as "Silicon Saxony." 14 GEAR GEAR
