Rapid prototyping of projects like this is a key part of the university’s mechanical engineering curriculum.
The university selected Objet 3D Printer due to high resolution and easy, safe operation.
The early detection of defects speeds up product development.
To get ahead in today’s job market, students need all the professional training they can get. The Rapid Prototype Laboratory at the Bremen University of Applied Sciences provides its students with practical experience in a simulated professional environment. After years of working with only a FDM system , the laboratory added an Objet Desktop 3D Printer. With this addition, the laboratory now supports all of the university’s education and research tasks.
For the University’s Mechanical Engineering Department, state-of-the-art integrated product development processes (such as CAD, CAE, FEM and Rapid Prototyping [RP]) are a core educational component and a standard pre-requisite for an in-depth engineering education. A system that enables students to design structures on a CAD system and produce them in a quick, cost-efficient manner is vital.
Ease of use and safety vital for student use
To be suitable for student use in a laboratory, a RP system must be both easy to use and absolutely safe for student operation. This means students cannot be exposed to any risks caused by the machine, its operation or to any hazardous substances released by the materials used during construction or in post-processing.
In view of all these requirements – high resolution, safe use and easy operation – the university decided that the Objet Desktop 3D Printer was the ideal solution for its laboratory.
“We owe it to our students to ensure that they receive the best education that we can provide,” says Prof. Dirk Hennigs, Mechanical Engineering Department, “By installing the Objet 3D Printer, we enable our students to gain practical experience with the systems they’ll meet in the real world when they begin their careers.”
Quicker design and realization
Through the Rapid Prototyping Laboratory, students get to know and use an up-to-date, innovative component of integrated product design and development during their professional education. This allows them to become aware of the potential benefits of this technology before beginning to work in their selected fields.
A cost-efficient system enables quick validation of 3D models within the framework of students’ construction projects, with early detection and removal of potential defects. Prof. Hennings notes: “The faster adequate prototypes are available for validation, the greater the costs saved by the early detection of defects. However, the early detection of defects does not only result in cost savings but also helps to drastically shorten production development cycle times, speeding up the development process.”
The Rapid Prototyping Laboratory supports the study program at the Bremen University of Applied Sciences through various student projects, from simple lab courses to applications within the framework of master theses. One project involves a test rig for examining the buoyancy of rotor blades. The Objet Desktop 3D Printer enabled the student to examine the aerodynamic properties of completely different wing profiles relatively quickly. After designing the wing profile on the CAD system, the student quickly printed the true-to-scale rotor blades on the Objet system and examined them in the test rig. “It became easy to optimize the profile, because new profile versions could be quickly generated on the CAD system and then output on the Objet 3D Printer for further testing,” recalls Hennigs. Thus, students were able to theoretically examine wing profiles and also to test them practically.”
