Inhalt des Dokuments
Hosted in the fully-equipped laboratory of the 3D Lab of the TU Berlin, this four-week course offers an introduction to working with professional 3D printing technologies such as laser sintering with polyamide and powder printing with mineral powder (modified gypsum). This course is aimed at those with an interest in 3D scanning and printing technologies and methods who want to gain insight into the work with professional 3D printing technologies and learn about current applications. As this technology covers numerous application areas, this course will be interesting for participants from diverse scientific disciplines (engineering, design, fine art or art history).
The course provides an introduction to manufacturing 3D printed objects with the laser sintering system and the powder printer of the 3D Lab, as well as data generation and data preparation for it. Participants will gain basic knowledge of the use of two professional 3D printing technologies, structured light scanners and related software.
Learning Goals & Syllabus
- To learn about theory and applications of manufacturing 3D printed objects with the laser sintering system and the powder printer of the 3D Lab
- Data generation and preparation for these technologies
- Knowledge of the use of two professional 3D printing technologies, structured light scanners and related software
You can find the syllabus for this course HERE .
We intend to adjust the syllabus accodingly to the preconditions and progress of the participants. Therefore slight changes in the syllabus of the course might occur during the course.
You may find the syllabus useful when discussing with your home University whether the ECTS credits attainable for this course are accepted by them.
The course starts with an introduction to the technologies used at the 3D Lab and selected projects from its portfolio, to give participants an impression of the various possible uses of 3D technologies. Ongoing course lectures will be accompanied by detailed practical units focusing on the use of the machines and the preparation of printable objects. Specifically, the practical training will develop student’s skills in the use of structured light scanners, 3D printing technologies, and in meeting the geometrical requirements for successful 3D prints. Please notice: we will focus on Selective Laser Sintering with Polyamide 12 and Binder Jetting (inkjet-based 3D printing) with specified Gypsum powder.
The general prerequisites of the TU Berlin Summer University are as follows: at least one year of university experience + English level B2 or equivalent.
An advantage of additive production is the possibility to construct and design objects and to correct or optimize them after evaluating the result of the 3D-print. Hence the course is usually focusing on a theme or a selected object, that is designed and constructed during the class and will be optimized in several steps. For the 2019 Summer University we have chosen a little (and easy to construct) toy plane.
Although our course is aimed at beginners, a specific minimum requirement is a basic knowledge of CAD software - participants must be able to handle 3D-construction or 3D-modelling software. We also recommend that students use their own laptops for processing their own 3D files with the software they are familiar with. According to CAD construction and 3D modelling we consider spatial imagination as a very helpful if not central skill.
We will send an email with a brief request concerning the skills of the participants after the registration is finished. Please respond to it, as this information will help us to prepare details of the course. Based on the experiences of the last years, our class will include an introduction into Rhino, which is the software that we mainly use for CAD construction at the 3D-Lab and in specific for presentations during the course. If you have good experience with other software (such as SolidWorks, ProE, Maya) you are invited to use it for your CAD construction on your Laptop using your own license. Please have in mind, that we cannot answer all questions regarding different software during class, due to prior knowledge of students.
What to bring to the course:
- Highly recommended: A laptop, preferably Windows
- The program GOM inspect (http://www.gom.com/3d-software/gom-inspect/download.html ): This program will be used to check the 3D scanned data and to repair them. Unfortunately this program is made for Windows only
- We recommend to download the test version of Rhino (https://www.rhino3d.com/download).  Rhino is a 3D constraticion software that we will use during the course. Please notice that the test version expires after 90 days of use. Do not download to early!
- The program Blender (https://www.blender.org/download/ ): Blender is an open source 3D modelling software and will be used to create objects from scratch. If you already own (and master) another 3D program – perfect!
- The program ZPrint (http://infocenter.3dsystems.com/product-library/z-printer/zprinter-software ): This program is associated with one of our 3D printers and will be used to preview your objects
- An object you would like to scan.
We will use two technologies of scanning: Structured Light Scanning and Micro Computed Tomography. The first one is scanning the surface of objects – the second is giving information about the whole volume. Because of practical considerations we would like to limit the scale of objects you can bring with you: The maximum scale for objects to be scanned by Micro CT should fit to a diameter of not more than 12 cm and the object should not consist of metal. Scanning with our Structured Light Scanner will not be so strictly limited regarding the size of objects. Anyhow we suggest to choose objects not larger than 30 cm in diameter. Very dark objects or those that reflect light very strongly are a little bit difficult to scan.
