The material validation process with the Pam Technology



Materials processable by the Pam technology

Pam is a technology dedicated to polymers treatment.
They are usually classified into different categories between amorphous and semi-cristalline, and using treatment temperatures from standard thermoplastics to performance and high performance.
As a dedicated technology inspired by micro-extrusion techniques, the Pam Technology is virtually capable of treating every kind of polymers.

The process of treating a material up to obtaining functional 3D printed parts requires going trough a validation process made of multiple steps. These steps can be more or less intensive depending on the family of the material.


Materials Pyramid
Legend

1 Processable material in the Pam Technology and multi-material printing profile available;
2 Processable material in the Pam Technology and printing profile available;
3 Processable material in the Pam Technology and printing profile not available;
4 Processability test to be performed.


Step One: Validation of the processability

In order to use a specific material with the Pam Technology, one should start by introducing it in the extruder and verify that it can go trough and be extruded. Non-degradation of the chemistry and consistency of the flow are the main points to look for here.
A lot of families and grades have already gone trough this first step at Pollen AM and none was impossible to work with. A subset can be seen in the above pyramid, and any specific inquiry can be adresse upon simple request.

Step Two: Elaboration of the printing profile

Printing a part with the Pam Technology is a lot about using the right slicing parameters. Working with a new kind of material, once it has been validated for processability, implies iterating with benchmarking parts over such parameters like temperatures, speeds, or extrusion dimensions. This collection of working parameters is called a Printing Profile.
Pollen AM delivers validated Printing Profiles that work for most of the applications with the materials it distributes.

Step Three: Refining for dedicated applications

Each application and each part can be meticulously optimised thanks to the variety of levers actionable within the slicer to work on specific part challenges, optimize dimensional fidelity or improve mecanichal properties.

Using specific grades with the Pam Technology
Proprietary or specific materials

Pollen AM can accompany its customers eager to work with a specific material or grade. Industrials can then enter a knowledge transfert process to learn how to work with new materials with the Pam Technology.
