Graphy Certification Training in Paris: Machines 3D Dentaire Reaches a New Milestone in Supporting Professionals

On March 21, 2026, Machines 3D Dental organized a new session of its Graphy Certification Training in Paris (12th arrondissement), designed for dental professionals looking to integrate resin 3D printing into their clinical practice. It was a packed day featuring scientific reviews, demonstrations, and hands-on experience with digital tools.  

With Dr. Akim Benattia serving as an instructor, Machines 3D continues its commitment to dental professionals and supports the healthcare sector in its transition to digital technology.

A training day combining science, education, and hands-on practice

The session on March 21 was structured around a program designed to combine theory with practical application. 

The morning was devoted to a review of several theses and scientific studies on the benefits of 3D printing in the dental field, presenting arguments highlighting the advantages of additive manufacturing (biocompatibility of materials, precision of orthodontic appliances made from resin).

The focus of the session, however, remained on practical application, beginning with a presentation of the digital workflow for aligners. Participants were able to get hands-on experience with the DAD and TeamGraphy software to walk through the entire process—from importing intraoral scans to modeling aligners, all the way through to preparing files for printing. 

A rigorous educational progression that enables practitioners to return to their practices with real-world operational skills.

From digital file to printed aligner: a streamlined workflow from start to finish

The afternoon provided participants with the opportunity to move on to the actual printing process, using Graphy TC-85DAC resin, a biocompatible resin specifically designed for the direct fabrication of clear aligners. This resin is recognized for its shape memory, transparency, and biocompatibility during long-term wear. 

The team from Machines 3D, Nicolas and Julien, walked the audience through the entire resin 3D printing process, highlighting several key points: safety protocols for setting up and handling resins, preparing the Uniz Ubee, and the rigorous post-processing required to ensure the aligners can be worn safely.

This day perfectly illustrates Machines 3D’s approach: to provide comprehensive, certified expertise so that every practitioner can independently and safely produce high-quality aligners for their patients.

We thank Dr. Akim Benattia for masterfully leading this “Graphy” training session and the participants, who came from all corners of France, for their active participation.

Each of the attending practitioners received a certification, a testament to their commitment during this training and their willingness to integrate new technologies to improve patient care.

Inspiring feedback from participants

As with previous training sessions, participants shared constructive feedback* on the March 21 session.

Hamza BENAISSA :  "The Graphy training session on March 21 in Paris was very interesting and enriching. However, I would like to attend again to explore certain aspects in greater depth and improve my understanding. I would therefore be interested in future sessions or any opportunity for additional participation."

Guillaume OGEREAU : "(The training) allowed me to get a fresh perspective on what’s being done today; it feels like direct printing is the next step rather than investing in a laser cutter! However, it’s a bit of a shame that there are currently so many different steps and software programs involved, but it’s clear that centralizing all these workflows is the next step. Maybe that’s the one I’m waiting for! " 

Emmanuel BOCQUET : "Saturday’s training was very interesting and helped me get a good grasp of printed aligners. I’ve received the quote for the printing line and now need to consider the budget to allocate and analyze the financial viability based on the feasibility of each case according to its difficulty."

This feedback builds on previous sessions and reflects the practical questions practitioners have regarding the integration of 3D printing into their practice.
