Technology & Products
Key Products
Liberty Pattern Company is a global leader in 3D printing, pattern tooling, fixtures, and machining services. They specialize in 3D sand printing for complex molds and cores using binder jetting technology, specifically with ExOne S-Max and Voxeljet VX1000 3D sand printers. They serve the aerospace, military & defense, aircraft, agricultural, and automotive industries.
Technological Advantage
Proprietary integration of binder jetting sand printing into traditional foundry workflows, achieving 99.5% accuracy for complex mold geometries; defensible through operational expertise and long-term customer relationships in niche industrial markets.
Differentiation
Value Proposition
Reduces lead times for sand casting patterns from weeks to days, enables complex geometries impossible with traditional methods, and provides on-demand production with high precision and consistency.
How They Differentiate
Focuses exclusively on sand casting applications with deep pattern engineering expertise, unlike generalist 3D printing services; offers faster turnaround (days vs. weeks) and higher precision for complex molds compared to traditional pattern shops.
