SLS works with a broad range of materials, including rigid thermoplastics, thermoplastic elastomers, polystrene, stainless steel powder, investment casting wax
, and ceramic powder.
The RP model is then used as a die for injecting investment casting wax
to produce casting cores and cavities.
This process allows a number of different powdered materials to be used, including polycarbonate, nylon, and investment casting wax
When casting wax
patterns, we recomand a wax temperature with 8[degrees]C higher than the injection temperature and a mould temperature between 30-35[degrees]C.
Vulcan Engineering showcased its new Tru Glu system for automated investment casting wax
pattern assembly, which uses robotics to build investment casting trees.
With further development, the process should enable rapid and economical generation of core and cavity inserts for direct injection molding of end-use production plastic parts, manufacturing large quantities of investment casting wax
patterns, and dies for direct die casting of production metal components.
The company has found that producing patterns with polycarbonate compounds, rather than traditional investment casting wax
, is ideal for casting metal parts with fine features and thin walls.
Biomet says the 3-D Modeler is attractive because it can make models from investment casting wax
