Lost Wax Casting Revamped Sla Rapid Prototyping Process-xhero

Business The most cost effective and practical method of creating steel .ponents that utilize the SLA rapid prototyping process is called investment casting. The lost wax casting process will most of the time produce a shape that meets the design needs of the end users of casting. The downside to the process is that the capital cost of building permanent tooling to replicate the patterns in wax on an ongoing basis can be quite costly. The cost increases when the engineer is attempting to predict whether or not the product will work as predicted. It may cost $10,000 just to replicate a tool using a 20lb investment casting. The most effective solution to keep costs down is rapid prototyping. Stereolithography Apparatus, or SLA for short, is a .mercially rapid prototyping process which is still widely used today, providing better accuracy and finish to a surface then other rapid prototyping technologies on the market. The Stereolithography Apparatus (SLA) Rapid Prototyping technique was originally developed by 3D Systems of Valencia, California back in 1986. SLA allows for a rapid prototyping service, turning a 3D CAD drawing into a solid object. Most SLA Rapid Prototyping can be used as master patterns for injection molding core and cavity inserts, thermoforming, blow molding, and various metal casting processes. Rapid prototyping exploits a SLA Pattern, which can be generated using a CAD file. SLA is a pattern used in place of a wax pattern for the lost wax process of investment casting. The result is a casting that can be put into use to prove the process without the heavy investment in permanent tooling. Below you will see the some benefits when utilizing the SLA rapid prototyping process. Requires no milling step or masking steps Uses a light-sensitive liquid polymer Inexpensive Investment casting patterns allow rapid production of metal prototypes Does not require much time Investment casting .panies across the nation have created castings for customer using the SLA Patterns. These investment .panies utilize the SLA pattern and processes it through the same manner as the wax casting pattern. This allows customers to evaluate the effectiveness of their overall design. Once they are verified, a decision can be made on investing in permanent tooling with the security of knowing the design functions properly with no additional changes needed.
