E-moto AGH is a team of students from AGH University of Science and Technology who built the first electric off-road motorcycle at the University. In addition to showing the advantages of alternative energy sources, they are also testing the newest solutions, like desktop SLS 3D printer Lisa Pro. Most of their construction work takes place at the university’s lab.
Additive Manufacturing (AM) is a wide term for a production process in which an object is produced "by adding material layer upon layer (and not subtracting material like in case of conventional machining)". Up till now, there are seven different types of AM processes, amongst which the most popular are: FDM, SLA, and SLS.
Could you imagine a product made all in one piece? We can, because SLS 3D printing technology makes it possible to print very complicated structures in just one take. But in real life, we are surrounded by objects made from a lot of parts that require to be connected somehow. Designer, even knowing the possibilities of SLS, sometimes needs to create models that are a part of something bigger. From this article, you will learn how to design connections for 3D printed, SLS models.
After 35 years of skyrocketing development of additive manufacturing, the market is full of different solutions. For the newcomer it is hard to figure out which one technology is a best fit, so the purchase decision is typically based on two factors: popularity and price.
Motivation of adjusting the printing parametersAs mentioned in the previous articles, there is a wide variety of polymer powders suitable for the SLS technology. You may ask, how come that the materials have such different properties? Polyamide (PA) is strong and resistant while thermoplastic polyurethane (TPU) is elastic and rubber-like. To answer those questions you need to zoom in into the molecular structure of the polymers.
Additive manufacturing irrevocably changed a lot of industries. It is impossible to imagine the future of automotive, aerospace or even medicine without rapid prototyping. Engineers and lab assistants are learning this new technology to become better-paid professionals. But essentially, to keep up-to-date with the fast-changing environment. What is the most effective way to learn advanced 3D printing technology?
Education sector uses 3D printers a lot. From simple and cheap FDMs to the most sophisticated metal printing devices. Teaching, testing, printing a lot. Those devices need to be simple, affordable, high tech and easy to repair.
In the previous article a brief overview on Selective Laser Sintering technique was presented and placed among other 3DP approaches. Now the time has come to dig down into the details of the SLS and unveil its phenomena. You can be confused on how exactly the laser sinters the powder, why we utilise elevated temperature or even why we can use one powdered materials and others not. This article will bring answers to those questions. We will also show the perspectives for research in terms of the SLS process and used powders.
Maciej Burzyński is a product designer in Sybet, a Polish company that creates integrated security systems for the mining industry. He carries enormous responsibility, not only for the usability but also for all of the technological and production issues. But what is most important, the cost-effectiveness of implementing a new product on the market.
Simon Grabowski is a young, talented technician whose professional career is just beginning. A few months ago, he started working on assembling 3D printers. Today, he creates tools to optimize the production of an international technology company. How did he achieve it?
