Development of models for forecasting and classification of a printing quality of a low cost 3D printer

At the present, the actual task is using 3D Printers for the manufacture of certain objects with a given level of price / quality ratio.

In many cases, it is economically feasible to use a low cost 3D Printer. Therefore, it is necessary to have models that predict and classify the printing quality of such printers.

The work has involved the development and assembly of a low cost 3D Printer. For this purpose, the creation of geometric models of the component parts and the printer itself was carried out, and engineering calculations and optimization of the received designs were performed.

It has been developed a printer control system. An experiment was conducted to produce cubes with different printing parameters on such printer. Based on regression analysis, linear and logistic regressions were constructed. Linear regression will allow to assess the quality level of the result depending on the printing parameters, and the logistic regression will allow to classify and predict the probability of manufacturing objects with a given quality level.

Aerialtronics' experience with the Stratasys uPrint SE Plus 3D Printer

As an small company with only 35 employees, a major challenge for Aerialtronics is to develop systems that could meet the requirements of a variety of industries without spreading its resources too thin between dozens of discrete designs. “We have developed a concept that uses a standard platform and is customizable to individual customers and applications,” explains Joost Hezemans, head designer at Aerialtronics.

In order to reduce development times and contain its costs, Aerialtronics sought a faster, more cost-effective solution than outsourcing. Working closely with Stratasys, the company installed a uPrint SE Plus 3D Printer: “With the uPrint 3D Printer, we can adjust a design one day and 3D print new parts overnight, test it, tweak it some more, and print another to test the next day,” Hezemans says. “This process means that designs have gone through between five and 10 more iterations than before. We have been able to 3D print more, see more and fly more than previously possible, and thanks to 3D printing, the product is much better."

Metal Plating UAV 3D-printed parts

Currently, Polymertal –global leader in metal plating solutions– together with a large Israeli defense company, are testing a unique large metal-plated 3D-printed part.

¿Why, and why now? Very simple: In recent years, more engineering-grade materials have become available for use with plastic 3D printers and these offer a good solution for metal replacement applications, including end-use parts.  ¿What if you could combine the advantages of plastic and metal together?

In the coming weeks the 3D-printed version of that end-use part will be assembled and tested on an UAV (Unmanned Aerial Vehicle). Success in testing would mean the defense company has a new option of performing a fully functional test of such parts which allows for faster design and testing cycles.

Metal-plating could enable the introduction of cost-effective hybrid UAV plastic parts with the following properties provided by the metal layer:

1) EMI/RFI Shielding

2) Electrical Conductivity (Plastic antennas, Wave-Guide)

3) Barrier Characteristics (offering protection from humidity, chemicals, fumes…)

4) Enhancing Mechanical Properties – over the original plastic parts design flexibility

5) ESD Protection

Metal plating is a method of depositing a thin layer of metal, usually Copper or Nickel, on an object made of a different material. This is done in order to improve one or more of the object’s properties, for example strength; thermal or electrical conductivity; chemical or heat resistance. ¿The result? a hybrid product and a new set of potential solutions for metal replacement applications.

Low-cost approaches to UAV design using Additive Manufacturing

Unmanned Aerial Vehicle (UAV) platforms are of major interest to Defense, Government, and commercial industries. The ability to remotely control an aerial vehicle capable of surveillance, offensive and defensive maneuvering, reconnaissance, or numerous other applications without the need to put a human life in jeopardy is a major attraction to their use. Furthermore, there exists opportunities to make these airborne vehicles largely autonomous, further reducing the need for even remote human operators. However, for all of the significant advantages of UAVs, there is a significant negative: the cost of manufacture, and the cost of design. Due in part to the substantial amount of complex electronic equipment on board, UAVs become not only a design of aeronautics, but an experiment in energy conservation through optimization. A limited range of UAV power becomes a limiting factor of UAV application. The challenge becomes to optimize the size, weight, and aerodynamics of the UAV based on the application.

UAVs con electrónica embebida

¿Es posible fabricar un UAV mediante Impresión 3D... y que lleve embebida la electrónica? La respuesta es SÍ, SIN DUDA.

El reto lo ha protagonizado Phillip Keane, estudiante de la Universidad Tecnológica de Nanyang (Singapur), quien ha diseñado y fabricado un UAV con material Ultem 9085, utilizando para ello un sistema de producción 3D Fortus 450mc. Aunque se trataba sólo de un prototipo, el reto demostró la posibilidad de llevar a cabo una fabricación automatizada de UAVs complejos y funcionales mediante impresión 3D.

Investigadores de la UTEP imprimen en 3D un UAV con insertos electrónicos

El encanto de los UAVs resulta cada vez más fuerte, y por ello no resulta extraño que se hayan podido completar ya un gran número de proyectos basandose en el uso de Sistemas de Impresión 3D. El ultimo de ellos lo ha protagonizado la Universidad de Texas El Paso (UTEP) que mediante un sistema Stratasys Fortus 400mc ha logrado construir un UAV cuya electrónica va inserta en su interior. De esta manera se consigue reducir y equilibrar el peso del UAV, sin sacrificar por ello el diseño final. En este vídeo se explica brevemente cómo lo hacen:

Win the Aerospace Arms Race with 3D Printing [White Paper]

In this white paper, Stratasys' VP Jeff DeGrange discusses the benefits and future of Additive Manufacturing in the Aerospace Industry. DeGrange discusses the scalability of 3D Printers and how they can print with various materials in almost any imaginable shapes. With a series of printers aerospace manufactures can build a fleet of prototypes, training mock-ups, manufacturing tools, UAV's, and even some finished goods.

Otro UAV mediante Impresión 3D, que sólo necesita dos motores

Trabajando desde el Modlab (acrónimo del Modular Robotics Laboratory) de la Universidad de Pennsylvania, el estudiante de ingeniería James Paulos ha conseguido simplificar el diseño de un UAV standard, sin reducir su funcionalidad. El hecho carecería de importancia de no ser porque el UAV en cuestión sólo necesita dos motores en total, y porque algunas de sus piezas pueden ser fabricadas mediante Impresión 3D.

Normalmente los UAVs requieren cuatro o más motores, mas incontables servos, acoplamientos, juntas de bolas, etc. Paulos ha optado sin embargo por un rediseño mucho más simple: “Los formatos de UAVs convencionales requieren complejos rediseños de todo el conjunto cuando tratamos de crear pequeños aparatos. Nosotros hemos optado por un diseño original basado en un nuevo rotor. Variando simplemente su angulo controlamos todo: velocidad, altitud, y aún orientación."
