| 3-D printed PLA material of a selected density is formed into a pattern that is configured as the outer shell of a casting form to be used in the lost foam or evaporative casting process. The purpose of 3-D printing of the PLA material is used to maintain the proper configuration of the form to facilitate casting, and reduce buildup of carbon on the surface of the casting. Because the form is essentially hollow, PLA support pieces can be used on the interior to maintain the structural integrity of the form. | ||||||

| 17 | Manufacture of metal foundry, foamed plastic and foaming polymer to execute the method | JP1651589 | 1989-01-27 | JPH01309749A | 1989-12-14 | WITTMOSER ADALBERT |
| PURPOSE: To manufacture a metallic foundry by a lost pattern foundry process in use of a casting pattern to be usable only once by adding one acting substance such as metallocene to prevent carbon from being formed in the case of gasifying a foamed plastic made casting pattern. CONSTITUTION: At least one acting substance containing at least metallocene and its derivative which partially or completely prevents carbon from being formed in the case of gasifying a casting pattern to be usable only once, is added. A foamed plastic is approximately completely melted or gasified by the heat and defects to be caused by solid carbon in the case of casting an ingot such as inclusions and carbonization on the surface are hardly generated thereby.

| PURPOSE: To improve the solubility of a ceramic core, and to maintain the dimensional stability at the casting temperature exceeding the prescribed temperature by forming the ceramic core to be used in the investment casting of a ceramic filler metal of the prescribed pts.wt., and the binder of the prescribed pts.wt. CONSTITUTION: A ceramic core has the composition consisting of, approximately 80-86 pts.wt. ceramic filler metal and approximately 14-20 pts.wt. binder prior to sintering. The filler metal has the composition consisting of approximately 66-95 pts.wt. Al 2O 3 particles, approximately 1-20 pts.wt. Y 2O 3 particles, approximately 1-5 pts.wt. particle growth suppressing material, and the balance scattering filler metal containing carbon. The binder is preferably the thermoplastic wax-based binder containing the reinforced wax. In the microstructure of the ceramic core, uncreacted Al 2O 3 particles are present, and the particles basically contain the polycrystalline composition of 3Y 2O 3.5Al 2O 3 on the surface of the Al 2O 3 particles. The ceramic core maintaining the chemical inactivity against the active alloy composition of the cemented carbide having the high melting point at the casting temperature, can be formed.
