New Voxeljet printer creates bigger parts

The first prototype of the machine debuted in 2020, he said.

“With our HSS technology, we are relatively new to the polymers market, but are much more established in other materials, such as sand, for example, which we print to create molds and cores for the metal casting industry. There, we have customers using our printers to produce over 100,000 of the same part per year,” he said. “We are in discussions with polymer customers about similar production volumes.” 

According to its manufacturer, the VX1000 HSS boasts fast and consistent layer times and produces high-quality parts. It can be used to make parts that are otherwise difficult to manufacture. 

“The VX1000 HSS enables the cost-efficient production of plastic components that can hardly, or not economically, be manufactured on an industrial scale using conventional injection molding. Without limits — around the clock,” the company’s website states. 

According to Reeves, the printers come with a tray, called a jobbox, in which the material being printed is inserted. The design of the jobbox maximizes the dimensions of the parts the VX1000 HSS can handle. 

printer and represents the full printing volume. The jobbox usually has a liftable floor that in the beginning of the printing process is lifted to the very top of the box. Then, with each layer, the box floor lowers exactly by one layer thickness (150 microns in HSS). Once the floor is fully lowered, the box is completely full with powder, in which the printed parts lie.”

The printer is fully automated and comes equipped with a large number of sensors, making it a good fit for smart production chains and applications that require traceability. 

It is easy to integrate into the entire manufacturing chain, Voxeljet says. 

Designed for processing polyamide 12, it can handle many other resins, according to Voxeljet. 

While Voxeljet calls the printer “an economically viable alternative to conventional plastic injection molding,” Reeves doesn’t view 3D printing and injection molding as rivals. Instead, the processes are complementary. 

“We don’t look at it as competing with injection molding — if a part can be injection molded, then it should be injection molded. 3D printing should be used when it adds value to the component; this is usually when the design becomes more complex and difficult to mold. Part consolidation, lightweight organic structures and mass customization are some of the leading design elements that can make 3D printing viable in production volumes.” 

Traditional manufacturers account for more than 60 percent of machine sales for Voxeljet, which has been supplying additive manufacturing technologies to metal foundries for over 20 years. 

“There is a significant opportunity for contract manufacturers. A 3D printed part has a higher value than a molded part of a similar size, so revenues are higher per part, which leads to higher productivity and greater profits,” Reeves said.
