Mack Prototype grows additive manufacturing capabilities with the addition of a Stratasys F770

Gardner, MA – Mack Prototype, a wholly-owned subsidiary of Mack Molding Co. focused on complex prototyping and low-volume manufacturing, has grown its additive manufacturing capabilities with the addition of a Stratasys F770 capable of producing large 3D printed parts.

The F770 is a Fused Deposition Modeling (FDM) system that runs both ABS and ASA materials. It features the widest build chamber of any Stratasys FDM 3D printer and a significant build envelope that spans 39 inches by 24 inches by 24 inches. That is 13-cubic feet of build volume allowing it to produce large parts or significant assortments of smaller parts. Typical part accuracy is +/- .010 inches (.254 millimeters) or +/- .002 inches/inches (.050 millimeters/millimeters), whichever is greater.

“We are excited to add the F770 machine, with Stratasys’ known track record for durability and reliability, to our fleet of 3D printers,” said Mack Prototype President Greg Cebular. “The new machine will allow us to print large parts as a single piece without needing to bond parts together, with applications ranging from producing large prototypes to large master patterns used in cast urethane molding and low-volume, batch runs of parts of various sizes.”

In the last 18 months, Mack Prototype has bolstered its additive manufacturing capabilities with more than $875,000 in investments in equipment and infrastructure. In addition to the Stratasys, the Company’s fleet includes a smaller format FDM printer, along with Carbon CLIP Digital Light Synthesis (DLS), HP Multi Jet Fusion (MJF) and Formlabs Stereolithography (SLA) machines. Whether its prototyping or production parts, the breadth of Mack Proto’s 3D printing services allows customers to match production solutions with their cost, material and end use parameters, while speeding up the product development lifecycle.

“From just a few parts to as many as a few thousand, our team of engineers can help customers with their low-volume and bridge production requirements with flexible solutions designed to deliver high-quality parts while reducing time and cost,” Cebular added. “Even better, if those production needs change we are prepared to help customers meet volume demand with traditional tooling, rapidly scaling production here or at one of Mack’s larger manufacturing centers.”
