3D Systems new high-definition 3D wax printers, ProJet CP 3000 and ProJet CPX 3000, is designed for creating multiple, finely detailed wax patterns using digital data.  The ProJet CPX 3000 is one of six new 3D printers built for office environment.  The wax materials are non toxic and environmentally friendly. 

Wax patterns produced on the ProJet CP 3000 are ideal for general foundary casting applications such as medium sized to large mechanical parts for engines, pneumatics, aerospace, custom manufacturing equipment, restorations and other heavy equipment.  

Traditionally the time taken to produce accurate sacrificial wax patterns for investment casting process has been time consuming and fraught with costly risks.  Thanks to 3D Systems wax printers, this is no longer the case. 

Using a 3D CAD design that is converted into an STL file format, the 3D printer is able to read the design and build the model layer-by-layer.  Parts with undercuts, overhangs and other complex features are no problem.  When the printing is complete, the part is separated from the platform, and support is easily disolved from the main component.  Dissolving the support wax is the only postprocessing needed as the surfaces of the remaining 100 percent “RealWax” pattern are smooth and do not require finishing. The patterns will perform like injected wax patterns in lost-wax casting processes and are suitable for direct investment casting applications using standard investment materials and casting procedures.

Large Parts for Casting

The maximum print size for the Project CP 3000 is 298x185x203mm.  Parts that are larger than this build envelope can be created in sections and bond together.  This method does not effect the casting process and will result in a single large metal part with complete structural integrity.

Benefits of Investment Casting

The investment casting process offers many unique benefits.  Examples of these benefits are :

•  Design Freedom: The investment casting process allows the designer the flexibility of nearly  infinite alloy choices, and great flexibility in external and internal configurations (aluminium is an exception but possible).
•  Unlike other casting methods, there are no draft requirements in the investment casting process, allowing for much more accurate dimensional conformance.
•  Reduced Machining: Investment castings are produced to close tolerances and near-net size. There is little secondary machining required, thus offering savings in machining time and material costs.
•  Mechanical Properties:  Investment castings will usually be able to meet the same mechanical properties of components manufactured from wrought metals.
•  Superior Aesthetics:  Fine details, text, logo’s and design features not attainable with other processes are possible.
•  Reproducibility: The investment casting process produces a reliable and consistent product.
