From Theory to Hands-On Expertise with AM Academy & FRAUNHOFER IAPT

Book your training now

Metal Binder Jetting is one of the most promising metal Additive Manufacturing technologies with a high potential for low cost and high-volume digital manufacturing. However, the complete process chain of Binder Jetting is highly complex and the supply chain is still developing. AM Academy created a unique binder jetting training course in cooperation with the FRAUNHOFER IAPT in Hamburg. Participants will learn the theoretical basics accompanied by a comprehensive hands-on session through the complete process chain.

Online learning, theory and practical sessions

Online Learning

Prior to the workshop participants get access to the self-guided online learning course Sinter-based AM Deep-Dive. The content covers basics of sinter-based technologies such as Binder Jetting or Material Extrusion.

Theory Session

On day one participants will be guided through the theoretical background of the metal Binder Jetting. The program covers a market and technology deep-dive, process parameters and material properties, design rules and as a deep dive into the cost structure. The day will be finalized with a tour through Fraunhofer IAPT’s facilities.

Practical Session

Day two will be the practical hands-on session. Participants will learn about data preparation, parameter settings and machine setup. Next, they will unpack a fully cured build job and prepare the sintering process. At the end of the day, each participant will take home their own Binder Jetting part.

Theoretical Binder Jetting Training

Metal Binder Jetting is a highly complex Additive Manufacturing technology with three major steps of printing, unpacking to sintering. The theory session will begin with a focus on the process parameters and resulting material properties. Based on this knowledge, design limitations and possibilities will be explained. In a practical session, participants will design their very own Binder Jetting component. In the last session of the Binder Jetting training, the cost structure will be covered.

Hands-on Preview

Binder Jetting hand-on training session

In Binder Jetting there is not only a printing process, but also highly complex depowdering and sintering to be considered. In the joint training of AM Academy and FRAUNHOFER IAPT, participants will learn hands-on how to prepare a machine for printing, how to unpack the green parts from the powder cake and prepare them for sintering. In several design examples, participants will learn about the influencing parameters of the sintering process. After this training, engineers, technicians and managers will have a clear understanding of the potentials and limitations of metal Binder Jetting.

Quick Facts

The first hands-on Binder Jetting training

The AM Academy and FRAUNHOFER IAPT Binder Jetting training is aimed for technicians, engineers and managers with Additive Manufacturing background, who want to understand the potential and limits of Binder Jetting hands-on. Participants will be enabled to make decisions based a training with current state of the art knowledge from an independent source with vast knowledge of the complete Binder Jetting process chain.

Sinter-based AM technologies and process chain

Sinter-based AM - a technology overview

Many different printing technologies - one sintering process

The sinter-based AM (SBAM) technologies have, as the name suggests, the sintering process in common. In this process, the printed green part is consolidated into a dense part and receives its final properties. The green part can be printed in advance using different technologies.They all have in common that metal powder is bound to the desired shape by a binder. The best-known printing technologies include Binder Jetting and Filament Material Extrusion.

In this section, you learn everything about the sinter-based AM  process chain and get an overview of the different printing technologies.

Goal and structure of this course

This course is aimed at engineers, designers and other professionals that are working closely with sinter-based AM technologies. The goal is to cover the most important aspects that will enable engineers and designers to fully grasp the capabilities and technical limitations of the printing technologies and the sintering process to succeed in technology selection and part design. Besides going through the course from the beginning until the end, this course can also act as a constant source of knowledge while working on AM projects. 

The course is structured into the following sections.

This section will start with an overview of the sinter-based AM process chain and its printing technologies, followed by a technology deep dive into the most important aspects of the BJT technology, followed by a closer look at the debinding and sintering step also including sintering simulation .

The second section will provide an overview of the different materials that are available as well as part characteristics that can be achieved with the BJT process and typical methods for quality assurance. Finally, several common defects in the BJT process are presented. 

The last section will act as a guideline for designers. Besides generally describing the process when designing for Additive Manufacturing, actionable restrictions and guidelines for the BJT process are provided. The final section will present several design examples from different industries. 

What you will find in this section

Sinter-based AM process chain

From digital model to finished part

Data preparation

Simulation to compensate the deformation during the sintering step, nesting of parts and definition of printing parameters

Printing

Through various printing processes, different feedstocks such as metal powders, filaments, pellets or dispersions are processed into green parts

Unpacking

Unpacking of fragile green parts needs to be done carefully and is typically a manual process.

Debinding

Debinding describes the process of removing the binder which results in a brown part

Sintering

To reach the structural integrity of a metal part, a sinter process is required. The powder particles fuse together to a coherent, solid structure via a mass transport that occurs at the atomic scale driven via diffusional forces.

The brown part shrinks ~13-21 % in each direction.

The process chain of sinter-based technologies differs from other AM Technologies. Especially the post-printing processes (debinding and sintering) are crucial to achieve the intended mechanical properties.

Technology principle

How does Binder Jetting work?

Binder Jetting is a powder based Additive Manufacturing technology in which a liquid polymer binder is selectively deposited onto the powder bed binding the metal particles and forming a green body.

The metal powder is applied to a build platform in a typical layer thickness of 40 µm to 100 µm. Subsequently a modified 2D print head apply a binder selectively onto the powder bed. Depending on machine technology a hardening or curing process of the binder is performed in parallel for each layer and/or at the end of the whole build. During the in-situ curing process a heat source is used to solidify the binder and form a solid polymer – metal powder composite.

Working Principle of Binder Jetting

Afterwards the build platform moves downward by the amount of one layer thickness and a new layer of powder is applied. Again, the liquid binder is deposited and hardened in the required regions of the next layer to form the green body. This process is repeated until the complete part is printed. After the complete printing process is finished the parts have to be removed from the “powder cake” meaning the surrounding loose but densified powder. To improve the removal of the excess powder from the green body often brushes or a blasting gun with air pressure are used.

To create a dense metal part the 3D printed green body has to be post-processed in a debinding and sintering process. Similar to the metal injection molding process BJT parts are placed in a high temperature furnace, where the binder is burnt out and the remaining metal particles are sintered together. The sintering results in densification of the 3D printed green body to a metal part with high densities of 97 % to 99,5%, dependent of the material.
