Researchers Develop a 3D Scanner Prototype for Applications in Diverse Areas


With the development of the mechanic and electronic parts of the device, the scientists of the Grupo de Energías Renovables (GER) of the Universidad Nacional del Nordeste are already working to shape a tridimensional scanner equipment (3D scanner) for diverse applications in areas like Odontology, mechanics and architecture, among others.

A 3D scanner equipment analyzes an object or scene to collect data about its shape and occasionally, its color. The information obtained can be used to build digital tridimensional models. The first scanners of this kind were used in industrial applications, but in the last years they have found a wide field in activities like archeology, architecture, engineering and entertainment (in the production of movies and videogames).

The first detail to highlight of the project of the GER is that, in Argentina, there are no more than three producers of this equipment, which might position them as another guide in the development of this technology boosted by the National Ministry of Science, Technology and Productive Innovation.

The process of tridimensional scanning involves disciplines from many fields of science: mechanics, electronics, mathematics, programming, optics (physics and geometry), electromagnetism, among others. Depending on the kind of application to which the 3D scanners will be submitted, they incorporate from simple techniques and devices to complex or high technology components’ systems.

As the project’s director, Doctor Arturo Busso, explains to Argentina Investiga, one of the challenges of the team of scientists is to select a scanning technique for the prototype. The possible techniques are basically optical. One of them uses cameras which capture the object’s image from different angles and then makes a composition of all the captures recorded. The second option uses laser: the object to scan is pointed with an open laser beam in the shape of a fan and a camera captures the object’s reflected image.

The choice of the most appropriate technique is not minor, as this will determine if the scanner is used in a reliable, simple and precise way rendering faithful dimension, texture and color information images.

Together with Doctor Busso, engineers Víctor Toranzos; Luciano Zini; Ramón Raúl Sánchez and Pedro Cossoli participate in the project. This group of professionals will have in their hands the shaping of the equipment’s control electronics, from the laser emission and the objects’ rotation to the mechanic structure and its interface with the image processing program to use.

The design of a data processing program is not included as an objective at this stage, but according to what Busso explained, they will choose one of the software packages available in the market.

3D ICTs Laboratory

Due to the fact that the GER currently has a 3D printer, the development of the scanner will permit as an additional result to implement a 3D ICTs’ laboratory which can be interesting for other scientific areas (Odontology, mechanics, architecture, among others).

In this sense, according to the scanner’s use, Doctor Busso explained that it might be a useful tool for the School of Odontology, as it can digitalize maxilodental pieces and then reproduce them through the 3D printer for practices and didactic models.

The project will involve an interdisciplinary work at the School of Exact and Natural Sciences and Surveying that will involve physicists, electric and electronic engineers. Due to the development’s nature, it is expected that the knowledge contributed will be used in disciplines related to control electronics, images digital processing and design of mechanic precision systems.

GER

The group started its activities during 1999 and it is interested in topics related to the application of renewable energies in its diverse ways: solar, eolian, biomass. Due to experimental needs, they have acquired capacity for innovation and development of highly specific instruments. It is integrated by researchers who develop their teaching activity in the School of Exact and Natural Sciences and Surveying of the UNNE, and keeps permanent relations for the academic and scientific support of groups of universities of the NEA, NOA of Brazil and Spain.

Nuevo Biosensor portable para la evaluación de la salud ocular

Nuevo Biosensor portable para la evaluación de la salud ocular

Un equipo de la Facultad de Ingeniería diseñó un dispositivo aplicado a la oftalmología, que permite el diagnóstico clínico de patologías de la superficie ocular con datos objetivos. A través de la modificación de una microbalanza de cristal de cuarzo, se la transforma en un biosensor para mediciones de lágrimas. El doctor Martín Zalazar, investigador e integrante del Laboratorio de Prototipado Electrónico y 3D, informa de los avances obtenidos en este desarrollo.

Innovadora plataforma para pacientes odontológicos que usan sillas de ruedas

El desarrollo tiene un propósito inclusivo, ya que apunta a facilitar el acceso de personas en situación de discapacidad a los tratamientos necesarios para el cuidado de su salud bucal. Sucede que el traspaso desde sus sillas de ruedas hasta el sillón odontológico implica ciertos riesgos y, en ocasiones, imposibilita la atención por parte de los profesionales. Fue ideado por un diseñador industrial egresado de la UNC. Obtuvo el primer premio en "UNC Innova 2017" y el segundo en el "Concurso Nacional de Emprendedores Metalúrgicos".
