The Z Corporation technology is another in the class of 3D printers for concept modeling. It uses a raster-based imaging style with multiple jets for good throughput. The print heads jet out a binder onto a bed of powder in multiple layers to form 3D parts. One unique feature of some of the Z Corp machines is their ability to make multi-colored parts directly in the machine using colored binders. This technology is not known for fine details, but with the recent introduction of a high-definition machine, it does pretty well. With post-build infiltration of hardening and strengthening agents, Z Corp parts can attain remarkable toughness. FineLine does not offer this service.
