Stratasys is launching a line of powder-bed-fusion-based 3-D printers appropriate for turning out production parts. 

The company’s new H Series Production Platform will use Selective Absorption Fusion (SAF) technology. The first printer in the line, the H350, was introduced April 27 and is expected to ship broadly beginning in the third quarter.

SAF is a new industrial-grade additive manufacturing technology that delivers production-level throughput for end-use parts, according to Stratasys, a manufacturer of 3-D printing systems. The SAF printers, which underwent more than 10 years of R&Dare capable of high-yield production of quality parts at a competitive cost, the company said. 

“3-D printing is increasingly transforming production in industries around the world as companies seek to move with more agility and efficiency, which is why we have put production parts at the heart of our business strategy,” said Omer Krieger, Stratasys’ executive VP of product strategy and corporate development. “SAF technology representa significant innovation that opens up new opportunities to address applications in industries such as automotive, consumer goods and electronics. As a result, we will enable a shift of many applications from traditional manufacturing and also enable the creation of products that can only be produced additively.”

SAF technology uses a counter-rotating roller to coat powder layers onto a print bedThe technology also selectively jets infrared-sensitive, high-absorption fluid (HAF) onto powder on the print bed. Industrial piezoelectric print heads jet single or multiple drops of the fluid in prescribed areas to create each layer of the part. This is followed by exposure to infrared energy, which causes the areas with HAF to melt and fuse together. The sequence is repeated until the parts are completed. 

The printer performs all these steps in the same direction across the print bed, which delivers uniform thermal exposure and consistent quality for all parts, regardless of their placement on the print bed, the company saidCuring an entire layer in one sweep of the infrared lamps is one factor that increases the speed of the process. 

SAF technology’s Big Wavepowder-management system distributes powder evenly across the print bed, maintaining a large, thermally stable flow of powder, the company said.

The H Series Production Platform can process a variety of materials, including polyamides and elastomers. In addition, Stratasys said its relationships with leading chemical companies will help it bring new materials to market quickly. 

Stratasys introduced two more new printers on April 27. The F770 FDM printer is targeted at large-part production, and the Origin One is designed for end-use manufacturing applications. Watch for more information about these printers on
