Metal Casting Service

Metal Casting Services On-Demand

For projects where you need metal casting, 3Diligent works with dozens of metal foundries across a range of materials. Whether you're seeking sand castings or investment castings, precious metals or industrial metals, we can meet your need.

3Diligent Material Options

3Diligent offers a range of cast metal options. A range of non-precious and precious metals are available for casting. As a general rule, precious metals such as gold, sterling silver, and brass are cast using the investment casting approach. Sand casting more heavily utilizes non-precious materials such as iron, steel, and aluminum.

Introduction to Metal Casting

3Diligent's primary metal casting methodology leverages our expertise with 3D printing. We offer two primary casting methods.

Beyond Metal Casting

In addition to metal casting, 3Diligent offers fabrication via other technologies such as 3D printing, CNC machining, and injection molding.

3Diligent example processes: investment casting, lost wax casting

Investment Casting

Casting is one of the world's oldest metal fabrication methods. In brief, metal is heated to the point it reaches a molten, liquid state. The material is then poured into a mold designed with the appropriate negative space and gating to allow the molten metal to effectively fill entirely. Once the metal has had time to cool off and set, the metal part can be removed from the mold for finishing. Investment casting also known as lost wax casting, is often used in the manufacture of jewelry and other intricate metal parts.


3Diligent technologies: sand casting

Sand Casting

With sand casting, the material used to create the mold is sand rather than ceramic. Given sand's more coarse texture, this technique is most commonly used for larger-scale castings that generally require less detail accuracy and tolerances. While sand molds can be created in various ways, at 3Diligent, the most common method we use is to actually 3D print the sand molds and cores. This approach can allow for a higher degree of complexity than typically permitted by more traditional approaches to sand mold fabrication. Additionally, because these complex patterns are printed rather than manually fabricated, it offers a much faster path to creating complex castings.
