Deliver processable materials optimized for injection molding and 3D printing.

Dynamik® sinterable products are unique feedstocks optimized for Metal Injection Molding (MIM), Ceramic Injection Molding (CIM) and Additive Manufacturing (AM) of metal and ceramic materials. Metal particles such as stainless steel, tool steel, titanium, and tungsten, or ceramic particles such as glass, silica, zirconia, or alumina are coated with Tundra’s proprietary technology (TundraKoat™) and combined with a polymer creating a feedstock. This feedstock can then be molded with traditional plastic and Metal Injection Molding (MIM) injection. These ‘green’ parts then have the polymer removed through a thermal or catalytic debind process and are sintered creating a metal or ceramic part. For metal products, the process delivers material performance like the wrought metal due to densities approaching 98% of theoretical values. These products are typically used in automotive, firearm, industrial, electronics, and medical & dental markets.

The process produces an unprecedented average part shrinkage as low as 6%. Dynamik® products also achieve favorable flow properties at up to an 88% fill volume using a variety of metal and ceramic fillers to produce net-shaped metal or ceramic parts that can the be post processed.

In addition to lower material costs and minimal shrinkage, this increased metal filler volume creates superior green-state part strength and durability that minimizes the need for supports with certain geometries. The proper rheology can also be achieved in a single step, resulting in additional savings due to increased throughput, less equipment wear and reduced infrastructure costs.

How Dynamik® Came to be:


The introduction of the Ikonik® platform in 2005 was a precursor to the birth of Dynamik® at Tundra.

Tundra began by loading stainless steel into a polymer at up to 75% by volume creating a high density flexible strip used in rotational balancing.

Due to TundraKoat™ enhancements, Tundra saw great improvements in:

  • Manufacturing
  • Self-Ordering of Particles Leading to Higher Packing
  • Improved Compounding and Extrusion
  • Enhanced Physical Properties and Flexibility

Platform Benefits:

  • High Dimensional Stability
  • Exceptional isotropic shrink characteristics
  • Large, high-complexity parts
  • Reduced part variability and high yield
  • Fusion by particle necking at lower temperatures, leading to improved dimensional stability in sintering
  • Exceptional green and brown strength parts
  • Multiple debind options; thermal and catalytic options available
