Hard tooling represents a massive financial risk for unproven designs. Our no-tooling casting approach removes the barrier of expensive metal molds during the development phase.
- Cost-Efficiency: Ideal for low volume production casting and bridge tooling where ROI on hard molds is low.
- Risk Mitigation: Modify designs instantly between iterations without the penalty of scrapping expensive tooling.
- Iterative Flexibility: Perfect for refining “problem parts” requiring multiple design tweaks before finalizing specifications.
How It Works: The SLA Rapid Casting Process
We streamline the traditional investment casting workflow by integrating advanced 3D printing technology. This hybrid approach allows us to deliver rapid prototype casting solutions that match the quality of production parts without the long lead times associated with metal tooling. Here is how we take your design from a CAD file to a finished metal component.
Step 1: Digital Pattern Generation via SLA
The process begins by bypassing the expensive and time-consuming creation of metal injection dies. Instead, we use SLA pattern casting (Stereolithography) to print a precise 3D pattern of your part. This printed pattern serves the exact same purpose as a traditional wax pattern but can be produced in hours rather than weeks. This method is ideal for complex geometry casting, allowing for intricate internal structures that would be impossible or cost-prohibitive with standard machining.
Step 2: Ceramic Shell Building
Once the SLA pattern is printed and inspected, we proceed with the standard precision lost wax casting shell-building process.
- Assembly: We mount the printed patterns onto a sprue or “tree.”
- Dipping & Sanding: The assembly is dipped into a ceramic slurry and coated with fine sand.
- Drying: This process is repeated multiple times to build a robust ceramic shell capable of withstanding molten metal temperatures.
Step 3: Precision Pouring of Alloys
After the shell is fully cured, we burn out the SLA pattern, leaving a hollow cavity. We then pour molten metal directly into this shell. Our facility handles a wide range of materials, ensuring that your prototype uses the exact grade required for final production. Whether your project requires specialized aluminum casting services for lightweight applications or robust stainless steel, we ensure the metallurgy is consistent.
Step 4: Finishing, Heat Treating, and CNC
A raw cast is rarely the final step. To ensure your functional metal prototypes meet strict specifications, we perform comprehensive post-processing in-house:
- Heat Treatment: We adjust the mechanical properties (hardness, ductility) to meet ISO standards.
- CNC Machining: For surfaces requiring extremely tight tolerances, we use advanced CNC mechanical processing.
- Surface Treatment: From polishing to plating, we deliver parts ready for immediate testing or market use.
Material Capabilities & Technical Specifications
When you need functional metal prototypes, the material properties must match the final production part exactly. We don’t use “simulant” materials; we pour the actual alloys required for your application. Our facility is equipped to handle a diverse range of metals, ensuring your rapid prototype casting performs realistically under test conditions.
Stainless Steels for Corrosion Resistance
We specialize in casting various stainless grades, including 304, 316, and Duplex stainless steel.

Frequently Asked Questions (FAQ)
Rapid Casting vs. DMLS: What’s the Difference?
While Direct Metal Laser Sintering (DMLS) prints metal powder directly, our rapid investment casting process uses SLA (Stereolithography) to print a disposable pattern which is then used in the traditional lost-wax process.
The main advantage of rapid investment casting over DMLS is material integrity. You get a true cast part with isotropic properties, identical to what you would receive in mass production. This makes it ideal for functional metal prototypes that need to undergo rigorous mechanical testing. DMLS parts can sometimes suffer from internal stress or porosity issues that cast parts do not.
What Are the Typical Lead Times?
Speed is the primary driver here. By using SLA pattern casting, we eliminate the need to cut expensive metal tooling, which usually takes weeks or months. Once the digital design is finalized, we can print the pattern and move to the ceramic shell building phase almost immediately.
- Quote Speed: We provide a response to inquiries within 8 hours.
- Production Speed: Without the bottleneck of hard tooling, we deliver quick turn metal prototypes in a fraction of the standard industry time.
