What is sintering for additive manufacturing?


Sintering for additive manufacturing is a process where a 3D printed part made from metal or ceramic powders is heated to near melting causing the powder particles to fuse together into a solid object.

The Problem


Sinter based additive manufacturing is too slow

Sinter based additive manufacturing of metal and ceramic materials is composed of two processes, 3D printing and sintering. During sintering, metal or ceramic particles are fused together to create a solid object. The problem is that conventional sintering processes currently available take days to complete.



Limited material availability and variety

Sinter based additive manufacturing systems currently available have closed material platforms with a limited number of metal and/or ceramic materials available. Additionally, the 3D printers in these systems are not able to print with other materials such as plastics and flexibles.


High equipment costs

Sinter based additive manufacturing system currently available are priced in from $120K to $400K+. An article titled “Obstacles to the adoption of metal additive manufacturing by small and medium sized enterprises”, written by the principals of Wohlers Associates and published in the Spring 2021 edition of Metal Additive Manufacturing, identified costs as one of the main obstacles in the adoption of metal additive manufacturing technology by small and medium sized enterprises.


The Solution


Metallum3D Additive Manufacturing System

Faster sintering - from days to hours

Our additive manufacturing system uses microwave energy and a granular susceptor material to rapidly and directly convert microwave energy into heat, which instantaneously heats up the entire the part, resulting in a significant reduction in sintering time.




Our microwave sintering process provides an order of magnitude improvement over existing conventional sintering technologies.


Open materials platform – multi-material 3D printing

Our additive manufacturing systems use materials in pellet form. Pelletized materials are the standard in the polymer industry. For plastic and flexible materials there are thousands of existing suppliers worldwide that supply these materials providing users of our system with an almost unlimited choice of materials. For metal and ceramic materials, Metallum3D has developed a water/gelation material formulation in pellet form that is cost effective, safe to handle and environmentally friendly. In our system, metal and ceramic 3D printed parts go directly from the 3D printer  to the microwave sintering furnace without the need for a debinding step. Our multi-material 3D printing capability delivers an “All-In-One” system.


Affordable System Price

Metallum3D is focused on providing our future customers with exceptional value. Our multi-material additive manufacturing system has been engineered to achieve a selling price point of $60K while still providing the company with robust gross margin targets. 

How It Works


Microwave Sintering and Granular Susceptor Material

Until now microwave sintering has not been commercially viable due to the limitations of existing microwave multimode resonant heating technology. This is the same technology currently used in domestic microwave ovens.  When applied to microwave sintering this technology has two major limitations. The first limitation is uneven distribution of microwave energy which results in uneven heat distribution during sintering. The second limitation is a reverse part heating profile where the interior of the part is hotter than the exterior of the part, which also results in uneven heat distribution


After 4 years of research and development work, Metallum3D has developed a new, patent pending non-resonant, microwave heating system that eliminates the limitations that have previously prevented the commercial use of microwave energy for sintering. Our microwave heating system uses specially designed non-resonant slotted waveguides and a specially formulated granular susceptor material to evenly distribute microwave energy within the sintering chamber resulting in even heat distributions throughout the sintering volume.


The microwave energy distribution of our non-resonant slotted waveguides has been validated using CST Microwave Studio, which is a high-performance electromagnetic simulation software package. The animation below shows a cross section of the microwave energy distribution of our slotted waveguides.



*Rendering of microwave heating system Images are computer generated demo versions. Product is not currently on the market.


Metallum3D has successfully conducted agglomeration tests on our granular susceptor material resulting in susceptor granules ranging from 3 to 5 mm in diameter as shown in the image below.



The image below is a schematic representation of our microwave sintering furnace.




Pellet Extrusion

To provide an open materials platform with multi-material capabilities, Metallum3D has developed a patent pending melt pump pellet extruder that accepts material in pellet form. Our extruder combines a zero-compression feed screw with a miniature positive displacement gear pump and three independent heating zones, to precisely control the extrusion and retraction of melted material flowing through the nozzle. This melt pump extruder allows our system to 3D print parts with plastic and flexible materials and to 3D print and microwave sinter parts with metal and ceramic materials. The image below shows a CAD model of our melt pump pellet extruder.

Metallum3D Partnership With Electrawatch Highlighted in Austal USA Press Release

3 months ago

On October 28, 2021, Austal USA issued a press released to announce the award of a contract to Electrawatch by the Office of Naval Research. Metallum3D partnered with Electrawatch to provide them with an additive manufacturing capability which uses the unique combination of bound pellet extrusion and microwave sintering.





Charlottesville, Va. – The United States Navy Office of Naval Research (ONR) awarded ElectraWatch, an Austal USA Company, a highly competitive Manufacturing Science Program contract to identify new material processing pathways that use additive manufacturing for Copper-Nickel (CuNi) heat exchanger designs. ElectraWatch was one of only five organizations, and the only non-academic organization, to receive a contract award.

“I’m proud of the hard work our engineering team has done to make this contract award possible,” ElectraWatch General Manager Ryan Dunn said. “We are honored that this award puts us in a position to further champion the next generation of manufacturing capabilities and to best equip the Sailors who protect and support our country and our allies.”

Dr. Scott Kasen, ElectraWatch’s principal engineer, explained that the enormous heat loads of future naval vessels require advanced designs for seawater heat exchangers which may only be achievable by leveraging the design freedom afforded by Additive Manufacturing (AM). “Despite the tremendous advancements in AM,” Kasen said. “Existing modalities are unable to easily process CuNi alloys which are chosen for their high thermal conductivity, demonstrated corrosion performance, and biofouling resistance in marine environments.”

To overcome the challenges of existing approaches, ElectraWatch partnered with Metallum3D to propose a novel AM capability which uses the unique combination of a bound pellet extrusion process and microwave sintering.

This project reinforces Austal USA’s position as a global leader in advanced ship manufacturing and sustainment. Investing in these future capabilities demonstrates the commitment of Austal USA and ElectraWatch to continue expanding post-delivery support and sustainment offerings, while also supporting multiple shipbuilders, maintenance providers, and the U.S. Navy across a broad range of military ships deployed in the U.S. fleet.

From Concept to Reality: How Metallum3D Uses Digital Tools for Design, Analysis and Manufacturing

5 months ago

Developing new products from concept to reality is a multi-step, multi-disciplinary process that is made easier by the abundance of digital engineering tools available today. As an example, we will showcase our use of digital tools for the design, analysis, and manufacturing of a non-resonant, transverse slotted waveguide that is used in our microwave sintering furnace.

Step 1: Design Calculations

The first step is to calculate the size and location of the transverse slots in the waveguide. This is accomplished using a spreadsheet in Microsoft Excel as shown in the picture below:



Step 2: 3D Modeling

The second step is to use the calculated values from the spreadsheet to build a three dimensional model of the waveguide. This is accomplished with the 3D modeling software SpaceClaim from Ansys. The resulting 3D model of the waveguide is shown in the picture below:


Step 3: Analysis

The third step is to use the 3D model to analyze and optimize the operational performance of the slotted waveguide. This is accomplished by analyzing the electromagnetic behavior of the waveguide using the software CST Microwave Studio from Dassault Systemes.  The analysis output for the transverse slotted waveguide is shown in the picture below:


Step 4: Manufacturing

The fourth step is to manufacture the physical slotted waveguide. This is accomplished by using Autodesk Fusion 360 software to generate a program to machine the slots from waveguide tubing using a CNC milling machine. Below is a picture of the simulated machining process in Fusion 360.



There you have it. These are some of the digital tools and processes that Metallum3D uses to go from concepts to reality!

First Principles Thinking : The Key to Innovation at Metallum3D

5 months ago

First Principles Thinking : The Key to Innovation at Metallum3D

First principles thinking, also known as reasoning from first principles, is a way of solving problems by reducing them to their basic elements and building from the ground up. First principles are foundational because they provide a strong basis for correct reasoning. Without them, our reasoning could be based on faulty assumptions.

First Principles Thinking at Metallum3D

At Metallum3D, we used first principles thinking to reduce the microwave sintering process to its basic elements in order to identify the technical challenges that were preventing the broad adoption of microwave sintering for additive manufacturing.  This led us to identifying two key technical challenges: The first challenge was the non-uniform distribution of microwave energy during sintering which resulted in uneven heating due to the formation of cold and hot spots as shown in the picture below.



The second technical challenge was the reverse temperature profile of a part during microwave sintering, in which the inside of the part is hotter than the outside of the part, resulting in an uneven temperature distribution during  sintering. This condition is shown in the picture below.



Metallum3D Technical Innovations from First Principles Thinking

From our first principles thinking approach it was evident that new, innovative solutions would be needed to overcome the technical challenges that have prevented the broad adoption of microwave sintering for additive manufacturing. Our research and developments efforts were concentrated in developing a microwave energy delivery system that would evenly distribute microwave energy and a means to equalize the internal and external part temperature profile during microwave sintering.  The focus provided by first principles thinking, resulted in the development of our non-resonant slotted waveguides, which evenly distribute microwave energy, and the development our granular susceptor material which provides for the equalization of the internal and external part heating profile during sintering.  These two new technical innovations are at the core of our intellectual property portfolio.
