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™ PATTERNS:

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:

Many foundries like working with wax patterns. Whether only one or hundreds of patterns are needed quickly, you can count on our ProJet® wax patterns to fit into your foundry processing procedures, just like any injection molded wax pattern. We provide high detail, high resolution ProJet wax patterns with the highest levels of surface finish required for demanding casting applications.

• Excellent for high detail, high resolution builds
• Highest surface level finishes and complexity
• Quick lead times
• Can be created without tooling
• Accelerates the casting process
• No special finishing required
• Lower cost of initial development
• Capable of producing the finishes required by the aerospace and medical industries
• Easiest patterns to process
