ZCast FAQ

What is the ZCast process?

The ZCast process involves directly casting metals in molds printed on selected ZPrinters. We are offering the ability to directly print the mold cavity or mold inserts. Traditionally, these molds need to be created by first producing a pattern (or pattern set) which would then be used to create the molds. In the case of sand casting, a set of patterns is used to create the impressions in the sand. In the case of investment casting, wax patterns are needed to then create a ceramic mold. With the ZCast process, we are offering the option to skip the pattern step.

What are the advantages of the ZCast process?

The production of prototype castings using conventional methods often can take several weeks and be prohibitively expensive. These constraints often limit the number or preclude the production of metal prototypes during the development process. The ZCast process can offer the opportunity to significantly reduce the time required to obtain metal castings while also reducing the cost.

Specific time and cost savings will depend on the size and complexity of the desired part, but can be substantial for many customer needs. For many parts, castings can be produced in as little as 1-2 days. The ZCast process also provides the freedom to produce more complex castings that previously were difficult to produce using conventional tooling methods. We recommend that the customer talk directly to Z Corp. and its partners to evaluate how this process may help them.

What are the new molds made of? Are they ceramic?

ZCast powder is a blend of foundry sand, plaster and other additives suitable for casting low temperature metals.

What metals can be cast?

ZCast 500 is a powder of set that allows casting of aluminum and other lower temperature metals like zinc and magnesium.

Will this capability be available on all Z Corp. machines?

The material is available for selected ZPrinters.

Will the printers need to be modified to work for this application?

The ZPrinter 310 Plus and Spectrum Z510 can be used unmodified.

What is the tolerance and surface finish that can be achieved with the ZCast process?

Customer parts produced have yield results that mimic traditional sand casting finishes and tolerances.

Can I machine the castings produced?

Yes. The cast metal part will have similar metallurgical characteristics as metal parts made using conventional casting methods.
