Investment casting has been successful in creating near net shapes for thousands of years. While the process has significant advantages, the high cost and time involved in the creation of tooling have limited the casting industry. We provide direct casting patterns produced with rapid prototyping technology, allowing more designs to be cast without the initial time and cost of wax pattern tooling.
Multiple 3D printing processes can be used to build investment casting patterns. Each process has advantages and disadvantages that will influence selection for your application.
QuickCast™ is an SLA build style trademarked by 3D Systems and was created to meet the needs of the investment casting industry. The QuickCast build style consists of a hollow SLA pattern with an internal hexagonal support structure that adds strength to the pattern, allows for easy drainage, and facilitates collapse of the pattern during thermal expansion to help avoid shell cracking. QuickCast patterns offer invaluable shrink and gating information prior to hard tooling, large pattern size, smooth surfaces, and accelerated timelines over tooling to create wax patterns.
• Hollow build style reduces the amount of material to burn out
• Commonly used by the casting industry
• Capable of producing large assemblies
• Highly stable CastPro™ resins developed specifically for foundry applications
• Rapid production compared to traditional tooling
• Provides invaluable shrink and gating information prior to hard tooling
• Low moisture absorption and expansion of pattern
• High dimensional stability
PROJET® WAX PATTERNS:
