ExOne’s InnoventPro Offers Larger Build Area, Faster Speed

The ExOne Co., maker of industrial sand and metal 3D printers using binder jetting technology, has debuted a concept rendering of the InnoventPro — an advanced entry-level binder jetting system for printing metals, ceramics and composites. The InnoventPro will offer two build sizes, a 3-liter and a 5-liter, with print speeds topping 700 cc/hour.

The system features an upgraded printhead that can more than triple print speeds, slashing the cost per part. It will also offer a new functionality in binder jetting with the option to 3D print a new class of patented NanoFuse binders embedded with nanoparticles to improve part quality and simplify sintering. Because nanoparticles fill in the interstices between powder bed particles and can bond at lower temperatures, they enable stronger green parts. In turn, this enables 3D printing of larger parts and finer features, delivering sharper corners and edges. These new binders can also improve the resolution and sinterability of high-demand metals, such as copper and aluminum.

The InnoventPro will feature the same recirculating printhead modules used on the X1 25Pro and X1 160Pro metal 3D printers, enabling users to easily scale up from R&D to high-volume production. The updated system is aimed at academics, researchers and a full spectrum of manufacturers, from machine and MIM shops to high-volume producers, who want to produce metal parts quickly, affordably and sustainably.
