Objet Ltd. (Rehovot, Israel) is expanding its line of simultaneous multi-material 3D printing technology to include a smaller footprint machine with a 260-by-260-by-200-mm (10.2-by-10.2-by-7.9 inch) tray size. Like its larger counterparts, the Objet260 Connex can print up to 14 different material properties within a single part thanks to the company's patented simultaneous multi-material jetting technology, it can also utilize the newly released acrylonitrile butadiene styrene (ABS)-like and transparent materials.

If you have a demanding molding and/or assembly job that requires the ultimate in machine orientation, Sherborne Sensors Inc. (Wyckoff, NJ) would like you to take a look at its T700 series of solid-state MEMS inclinometers. The company claims the sensors enable high-precision inclination measurements with accuracies better than 1 milliradian over angles of ±30° to ±90°.

Balancing pressure front

By IMM Staff
Published: December 3rd, 2009

Automatic detection of the melt front using cavity pressure sensors can now be used to initiate reliable, fast, and automatic switchover to holding pressure thanks to a patent-pending development at sensors and process controls supplier Priamus System Technologies AG (Schaffhausen, Switzerland). However, the company believes the biggest impact of this development will be in automatic hot runner balancing where not only temperature sensors, but now also pressure sensors can be used.

Precise nozzle pressure

By IMM Staff
Published: October 30th, 2009

Melt pressure in front of the injection screw is an important process parameter for precision processing and machine control is critically dependent on its precise measurement. This is because injection molded components can only be kept within extremely tight tolerances if this pressure can be accurately and repeatably measured and recorded over an extended period.
