DEARBORN, MICH.—Stratasys Inc., a rapid prototyping equipment supplier in Eden Prairie, Minn., has introduced a new fused deposition modeling machine designed to create large prototypes.

The FDM 8000 uses ABS modeling material to create tooling patterns, masters and functional prototypes for testing.

The unit can generate prototype parts as large as 18 by 18 by 24 inches and can operate unattended.

The new machine complements Stratasys' recently introduced FDM 2000, a high-speed unit that can build models from a variety of materials that include ABS, medical-grade ABS and investment casting wax.

The FDM 2000 is similar in design to the FDM 8000 but accommodates smaller-sized prototype models.

Throughput on both machines is 92 percent faster than using traditional stereolithography methods, the company said. Build time for the FDM 2000 takes a little more than five hours, compared with more than 10 hours for an SLA 250 machine from 3D Systems Corp. in Valencia, Calif., according to a Stratasys news release.

Stratasys uses a patented fused deposition modeling process that extrudes three-dimensional ABS, wax or elastomeric models directly from computer-aided-design files.

The FDM 8000 has a $200,000 list price, and the FDM 2000 sells for $165,000.
