Open to material technology
A range of services for a turnkey solution.
3D printing technologies offer to manufacturers a flexible means of production with new freedom in part design. In order to take advantage of this flexibility and to integrate this new means to the best of their existing industrial tool, Pollen AM designs and manufactures open solutions that guarantee users control over the materials to be transformed.
A Pam system is thus an industrial tool capable of adapting to the material thanks to a development methodology developed by Pollen AM. This methodology is presented in detail during the training course available online on the e-learning platform set up by Pollen AM. The development steps are also proposed as a service.
From the qualification of a specific material to the part production and their mechanical characterization, Pollen AM accompanies you in the validation of Pam technology in relation to your industrial needs.
Preliminary material analysis
The material qualification corresponds to the empirical study of the behaviour of a material during its transformation by a Pam system.
Indeed, the dimensions and the design of Pam extruders induce a particular behaviour of the material.
Objectives: The study of this behaviour allows giving an estimation of the machine parameters to be used and the resolutions that will be possible to develop.
Discuss with our experts
The realization of the service is made from:
- 5 kg of the material to be qualified provided by the applicant;
- all the technical documentation of the material (MSDS, TDS, Process guidelines, etc.).
The service concludes with the delivery of a technical report including :
- The range of values of the parameters to be used for a profile development;
- The presentation of the compatible output nozzles and the achievable resolutions after profile development;
- A study of the level of interlayer adhesion.
Finally, a hexagon is produced at the end of the qualification. This printing demonstrates the ability of the Pam system to shape the material and presents the material aspect.
Observation of free extrusion behaviour (no nozzle mounted).
Study of the extruda quality (regularity, no degradation observed, no bubbles, etc.).
Observation of the extrusion behaviour (nozzle mounted).
Iterative work to optimize the inter-layer adhesion and the extrusion flow rate.
Tailored settings for reliable applications
Profile development is the focusing operation that sets the printing parameters and Pam configuration to be used for stable, repeatable and quality printing.
Based on the need expressed on the resolution of the profile (nozzle diameter and expected layer thickness) and in accordance with the conclusions of the qualification report a profile is developed tailor-made for its future application.
The generated parameter file is delivered to the user. It can be used on any Pam system with the required configuration to produce parts in the requested resolution.

Multi-material 3D printing profile development
A multi-material application comes either from a need to combine several materials to make a part or from the need to use a support material to build a given part.
This particular development work focuses both on profile development for each material as well as compatibility and print management at the interface between materials.
Once again, this service is based on a specification expressing the need for resolution for a tailor-made development. Similarly, the deliverable delivered at the end of the service is the parameter file used, plus a part made with it.
Discuss with our engineers
Pollen AM offers manufacturing services taking into account the expressed material requirements. The direct printing of a part is only possible if the desired material has a printing profile corresponding to the expected resolution.
The continuous profile development work carried out by Pollen AM's technical teams offers a catalogue of materials in connection with resolutions that can be used directly for the production of parts.
If the existing offer does not meet the part specifications, two solutions are to be considered:
- Launch material qualification work and then develop a print profile if the qualification report validates the requested resolution;
- Launch a profile development from an equivalent material already qualified by Pollen AM.
In conclusion, the flexibility and openness of Pam systems allow the development of customised printing profiles including the functions necessary to meet the most demanding needs.

Mechanical characterization of the printing profile
International norms compatible
The printing strategy and the parameters used to affect the final mechanical characteristics of the part. Thus, to validate a printing profile used for the manufacture of parts integrating mechanical specifications, Pollen AM provides characterization services carried out with partner laboratories.
Test specimens are printed from the profile to be validated and are then used in characterization tests. This service ends with the delivery of a test report showing the levels measured according to the printing strategies used during the tests.
