Mirai3D uses 3D printing to develop models for surgical preparation

An Argentine surgeon collaborates with engineering company Mirai3D to 3D-print medical models so he can better prepare for challenging surgical interventions. Mirai3D based on BCN3D’s Sigmax 3D Printer. With 3D printed models, doctors often gain a better overview of the patient’s body situation and improve surgical planning.


The Argentine surgeon Dr. Gustavo Nari works with the engineering office Mirai3D Collaborated in designing and manufacturing medical models that augmented the surgical planning process with the help of IDEX Technology BCN3D Significantly improved Sigmax printer. BCN3D reported this to the magazine 3D Without Borders in a press release.

Mirai3D is a biomedical startup focused on 3D printing, virtual reality and advanced materials in the healthcare field.

3D printed models to improve preparation for surgery

Doctor. Gustavo Nari of the Hospital Transetto Caceres de Allende in Cordoba has created medical models to design surgical plans that improve anatomical understanding of clinical cases. In areas such as oncology, challenging interventions that require doctors to work or move vital organs are often required. In order to be optimally prepared for such an operation, it helps doctors plan access routes and get a better picture of the posture on the body and the possible course of action. This also reduces the risk of difficulties during the operation.

Doctors can use a patient’s scans to create a hypothetical model of the area involved. The pattern can be printed in its original size. IDEX technology works with different materials in 3D printing in order to reproduce different parts of the body, such as bone or tissue. Thanks to IDEX technology, a variety of colors can also be used for printing, giving the clinician a very accurate and detailed image of the operating area. The patient and relatives also benefit from this model, as they can be better aware of the situation.

The surgical intervention was successful thanks to the support for 3D printing

A 65-year-old woman with a right lobe liver metastasis and a small left lobe metastasis should undergo surgery. The complex history requires a very careful approach. Doctor. Nari was printed with inexpensive PLA using 0.02mm FFF 3D printing technology. The procedure was successful thanks to careful preparation. The subtle detailing and coloration of the vessel models helped the doctor avoid bleeding, which would have been very dangerous for the 65-year-old because of her medical history.

Many medical institutions use 3D printing to prepare for the procedure with accurate models. In addition to oncology, pediatric surgery is also an important area, given that the organs there are smaller and the operations are more difficult. Pediatric cardiac surgeons at Inselspital Bern prepare for the procedure using 3D printed heart models. The University Hospital Leipzig also uses 3D printing for preparation.
