Why Ident’M chooses the J5 DentaJet 3D dental printer from Stratasys

France-based medium-sized dental laboratory Ident’M say it is now producing around 1000 dental parts each month at 18 microns precision thanks to the large capacity mixed-tray printing capability of its Stratasys J5 DentaJet™ 3D printer. A spokesperson from Stratasys explains.

Ident’M is transforming the production of dental parts and addressing an inherent challenge for greater accuracy and precision at its Saint-Etienne-located facility. Previously, although Ident’M had moved from the creation of plaster models to 3D printed versions, quality had often been an inherent issue, affecting approximately 50% of prints.

Olivier Mangot, Co-director at Ident’M, said: “For us, delivering a prosthesis without a reference model is inconceivable, but depending on the 3D printer used there are deformations. We were also constrained by the lengthy production time required to produce dental models.

“We knew we needed a 3D printer that would deliver a higher-level of precision and faster production speeds, as well as being user-friendly, and the J5 DentaJet from Stratasys meets our precise requirements for increased precision, down to layers that measure just 18 microns. It also enables us to develop a greater variety of models and devices far more efficiently than we could previously.”

Ident’M Co-director, Frédéric Imbert takes up the thread: “Since it was installed in late 2021, the J5 DentaJet, using PolyJet technology, has had positive benefits for us in several different areas. For example, we have an obligation to deliver superior precision to our clients, and this 3D printer’s precision is simply unachievable with any other technology today.

“We have also been able to save time and improve productivity by producing multi-material models on one J5 instead of three 3D printers that were dedicated to three different applications.

“This is helped by the Stratasys printer’s large-capacity 360-degree rotating build tray, which allows our technicians to simultaneously 3D print various models and dental devices in multi-materials and colours. These include rigid and opaque implants, soft gingiva masks and transparent or biocompatible options for surgical guides.

“The unit works at a level of reliability that enables the J5 to operate around the clock. We’re running the J5 20 hours a day, right through the night, which is currently seeing us create around 1000 different models a month. This is a massive benefit, as it means we arrive the next day with a full tray of models.”

Mangot adds: “Ultimately accurate 3D printing is also a big help to the patient and the dentist, who, to get a good fit, can reliably count on just two appointments, instead of as many as five. Previously a typical scenario might see a patient visit the dentist, who will then prepare a crown and produce a metal framework.

“The patient returns to have it fitted and the device will go back to the lab. There might be the need for adjustments, which demands another fitting before finishing, which all in all demands four appointments ahead of a final validation.

“But now, by using a digitised process with the J5, we can do everything in just one appointment, with a second required simply to insert the crown in the patient’s mouth. This has led to some very positive feedback from our customers.”

The J5 DentaJet is the only multi-material dental 3D printer that enables technicians to load mixed trays of dental parts. It can produce at least five times more dental parts on a single mixed tray than competitive 3D printers, yet its compact footprint uses only 4.6 sq. ft (.43m2) of floor space.
