Sand Casting Patterns
At Polymerate Labs we convert your digital CAD files into physical master patterns using industrial FDM technology, replacing traditional wood and metal patterns.
Stop waiting weeks for wooden patterns. We print complex master patterns in ABS/PLA that are ready for sand ramming in days. Our process handles complex undercuts and integrated gating systems without the need for skilled carpentry.
Advantages
3D Printed Sand Casting Patterns with Polymerate Labs
Lead Time Reduction
Foundries can start sand ramming days after the design is finalized, not weeks. ..................................................................................................
Cost Efficiency for Low Volumes
Our printed patterns can save up to 75% in tooling costs compared to traditional methods.
Dimensional Accuracy & Consistency
FDM printing offers high dimensional precision directly from the digital model, eliminating human errors inherent in manual wood carving.
Complex Geometries & Design Freedom
Our additive process can create complex features like deep undercuts, integrated gating systems, and thin walls that are difficult or impossible to machine in wood or metal.
Digital Warehousing
Need a replacement pattern 2 years later? We simply "re-print" the exact same file. You save on storage costs and maintenance.
Fast Delivery
We deliver your products in 48-72 hours if in Hyderabad or 3-5 days across India.
Materials
ASA, PETG, ABS, PA, PA6-GF, PLA+-CF. Choose your materials based on the number of cycles the pattern is used.

For prototypes and low-to-medium production runs, yes. 3D printing eliminates the high setup costs of CNC machining and the labor hours of woodworking. However, for mass production (10,000+ castings), a traditional metal match plate may still be the standard choice. We are the ideal solution for urgent replacements, prototypes, and short-run batches.
Yes. We adjust the internal density (infill) and wall thickness of the print based on your foundry’s specific process (manual vs. machine molding). For high-pressure lines, we use high-strength materials like Glass/Carbon-Fiber PA6 with solid shells to ensure the pattern does not crush or deform.
It depends on the material selected:
Standard PLA: ~10-50 impressions (Ideal for prototypes).
Industrial ASA/ABS/PETG: ~100-500 impressions.
Carbon/Glass Fiber Composite (PA6,PETG): 500+ impressions (Comparable to some aluminum patterns for short runs).
