Material 3D 3DMT specializes in metal additive manufacturing and the key component of the technology is material. With a long history of powder metallurgy in ARC Group, this experience transfers to 3DMT with metallurgists on staff, on-site material testing capabilities and heat treatment knowledge.

3D Metal Printed Prototypes
3D metal printing is an advanced, next-generation additive manufacturing process for making complex parts with features that cannot be produced by any other method. Parts are created on a special machine layer-by-layer, and this unique process lets you – the product designer – add internal features like conformal cooling channels and lattice structures to reduce weight while preserving strength. Because the process is completely computer controlled, you are also able to modify features quickly and easily without additional expense, allowing you to test different versions of a prototype fast. Prototypes can be made in stainless steel, aluminum and titanium.

SLA & SLS Rapid Prototypes
SLA & SLS are two of the original 3D printing processes. These methods are ideal for making rapid, one-off prototypes in plastic. These prototypes can be used as-is, or to function as master patterns for polyurethane vacuum casting. Like with other 3D additive manufacturing processes, you can add complex internal features that can’t be made conventionally.

Polyurethane Vacuum Castings
Polyurethane vacuum casting  is a rapid prototyping technique suited for making up to 30 copies of a master pattern from a silicone rubber mold. The level of detail and surface finish of the copies is dependent on the quality of the master pattern. You choose the casting compound to match your design idea – hard or soft, colored or clear. We even offer overmolding to combine two or more different types of material in a single finished casting.
