Cast Metals, also known as Lost Wax Casting, is a centuries-old metal casting technique used to create intricate jewelry, sculptures, and functional metal objects. By using 3D printing to create precise wax patterns, designers can achieve exceptional detail, complex shapes, and professional finishes that would be difficult or impossible with traditional metalworking techniques. This method is perfect for crafting custom jewelry, decorative home goods, collectible miniatures, and one-of-a-kind accessories. With a variety of metal options and post-processing techniques like polishing and plating, wax casting combines tradition with modern innovation to bring your most intricate designs to life.
Cast Metals are ideal for projects that require fine details, smooth finishes, and unique metal properties. Some of the most common applications include:
Custom Jewelry & Rings
Create intricate, high-quality jewelry in gold, silver, platinum, and bronze.
Art & Sculptures
Produce detailed, ornamental, or miniature sculptures with a professional finish.
Home Decor & Accessories
Design custom brass, bronze, or copper decor pieces for a unique touch.
Interlocking & Moving Parts
Craft mechanical or fashion accessories with built-in moving components.
Personalized Gifts & Collectibles
Bring customized metal products to life, from keychains to designer keepsakes.
If your design requires intricate patterns, fine engravings, or custom metal finishes, Wax Casting is the perfect technique.

Design guidelines
3D models may shrink about 0.25 mm plus 2.5% after casting and finishing as part of the 3D Brass printing process.
For rings, the inner diameter is accurate within +/- 0.1 to 0.15mm. On average, the model shrinks about 2.5% after casting and finishing. We do our best to polish the internal diameter to match your model file during the 3D Brass printing process.
Your Bronze 3D printing model may shrink about 0.25 mm plus 2.5% after casting and finishing.
For rings, the inner diameter is accurate within +/- 0.1 to 0.15mm. On average, the Bronze 3D printing model shrinks about 2.5% after casting and finishing. We do our best to polish the internal diameter to match your bronze 3D printing model file.
±0.125 mm, Models can shrink about 2.5% after casting and finishing.
For rings, we do our best to polish the internal diameter to match the dimensions of your model file.
Natural:
When you 3D print Silver, the model may shrink about 0.15 mm plus 1.5% after casting and finishing. For rings the inner diameter will be 0.125 - 0.15 mm smaller than your design. On average, when you 3D print Silver, the model shrinks about 1.5% after casting and finishing. Scaling up your model by 1% will make your design closer to your desired size.
Polished, Fine Detail Polished and Antique:
