Sinter-based Additive Manufacturing complements Metal Injection Molding (MIM), offering even more design flexibility and scalability for complex parts in small to medium quantities, using for example stainless steel and titanium.
Additive Manufacturing
Key Facts
Sinter-based Additive Manufacturing enables the production of geometries too complex for Metal Injection Molding or where the tooling investment is impractical. The printing processes used at MIMplus Technologies enables the economic production of small to large quantities.

Additive manufacturing
Advantages - Case study
Integration of functionalities
Additive Manufacturing offers exceptional design freedom, allowing for features such as undercuts or curved guiding channels inside.
Ultrasonic Bath Washing
To ensure the absence of production residues parts are washed in an ultrasonic bath.
Titanium
Even components made from materials that are difficult to machine can be produced cost-effectively using Additive Manufacturing.
Laser Marking
Enabling the tracing of parts and the attribution of each part to a specific production and material lot.
Blasting and Tumbling
To achieve a smooth surface, the parts are blasted and vibratory polished.
100% Testing
Providing and guaranteeing 100% functionality by testing each part individually.

Additive Manufacturing
The process
AM is a four-step process for producing net-shape parts with very complex geometries and functionality. Except for the step where the green part is printed, the sinter-bases Additive Manufacturing process is largely identical to the Metal Injection Molding (MIM) process.
Feedstock or Paste
Fine metal powders are mixed with thermoplastics and additives. They can be printed in solid feedstock form or via suspension.
Additive Manufacturing
Green parts can be printed by different sinter-based additive manufacturing technologies like cold metal fusion or moldjet.
Debinding
Debinding removes most of the binder, leaving 2-3% residual binder to stabilize the "brown part" for the next step.
Sintering
In the final step, components are sintered at 1200°C to 1400°C, removing all remaining binder.
Additive Manufacturing
Materials
Low-alloyed steels for heat treatment
Low-alloyed steels contain small amounts of alloying elements (up to ~5%), enhancing hardness, strength, and wear resistance. These materials are typically used heat-treated, and offer good hardness, toughness, and fatigue resistance, making them ideal for technical components in machinery industries, aerospace or automotive.
Tool steels
Tool steels are high-performance steels designed for highly loaded components in demanding applications. Such steels show a high hardness, wear resistance, and toughness. These steels are ideal for high-stress applications offering excellent durability and strength in industries like automotive and manufacturing.
Stainless steels
Stainless steels are corrosion-resistant alloys that offer excellent resistance to rust and oxidation, making them ideal for harsh environments. Used in a wide range of applications, including medical devices, aerospace, machinery industries and consumer.
Titanium
Titanium and Titanium alloys are lightweight, corrosion-resistant metals known for their high strength-to-weight ratio. Titanium is commonly used in aerospace, medical, and high-performance applications requiring durability or biocompatibility.
Copper
MIMplus offers several further alloys for demanding applications. On customer demand MIMplus can develop feedstocks in-house or with qualified suppliers.

MIMplus offers several further alloys for demanding applications. On customer demand MIMplus can develop feedstocks in-house or with qualified suppliers.
Moldjet is a powder-free AM technology that enables the industrial-scale production of metal components. It is designed to produce parts with complex geometries, high density, and exceptional mechanical properties. Moldjet can reliably produce components in different versions and with different geometries and applications.
Cold Metal Fusion (CMF) is a process that integrates metal powder into a functional binder system, enabling the production of metal parts using existing Selective Laser Sintering (SLS) printers.
