First off, what’s a Maggy? Maggy is a small wearable device helping you to maintain social distancing while keeping your privacy. It creates a sound and vibration notification whenever the distance between its users becomes too small. The reason why Maggy relied on a combination between a small wearable device and an optional mobile application, is manifold. On the one hand, there’s accuracy – Standard smartphone Bluetooth chips have an accuracy up to approximately 1 to 2 meters, whereas Maggy contains state-of-the-art Bluetooth 5.1 and 5.2 chips, characterized by accuracy of approximately 10 to 15 centimeters.
If we can describe what drives cost-efficiency of SLS 3D printing it could be done in two words: refresh and pack. Today we introduce the lower refresh ratio of our PA12 powder. The extreme 26% was achieved. There are a lot of myths around SLS 3D printing. Some people still think that it is an expensive technology. But since Sinterit introduced small SLS 3D printers but with comparable quality and precision as the industrial machines, the expensiveness of the process is not a problem anymore. - The total cost of using the machine is the purchase of equipment, service, and material. We've just improved this third parameter, by lowering the amount of powder in the refreshing cycle. We've already revolutionized the cost of the system and service, now it's time for reducing the cost of printing. - says Konrad Głowacki, co-founder of Sinterit responsible for powder development. For those who are not familiar with SLS 3D printing technology, let’s explain the basics. SLS operation principle is powder sintering with the help of infrared laser in elevated temperature which helps the grains of the powder to consolidate before being bound with the laser beam. In the conventional SLS printer, there is a so-called “bed” on which the roller spreads a thin layer of powder followed by sintering according to the layers sliced from a 3D model file (e.g. a .stl file (derived from CAD-like designing software). Why powder refreshing ratio is so important? What is important: not all the powder is sintered during the process. Only the part which builds the object. The rest of it works as a natural support. The unsintered powder can be reused in other prints just after adding some fresh powder. The needed amount of the additional refreshing powder is responsible for the final costs of 3D printing in this technology. As you can easily assume, the lowest ratio of refreshing powder means the best ROI. Sinterit was always a leader in this aspect, but now the company lowered it even more to 26 percent. Huge amounts, so cost efficiency is key. Stefan invests time to optimizes the working area of his Sinterits LISA 3D printer. Which, combined with a low refresh ratio, allows him to get a low printing cost. This is the best way for SLS usage, especially when it comes to production. - Our way is to make 3D printing technology more accessible. Lowering the cost of prints is just the next step. Not the last. - says Maxime Polesello - CEO of Sinterit.
New 6 kg packages for the most commonly used powdersTo optimize the workflow and reduce the amount of waste, we have introduced new packaging of the most commonly used powders: PA12 Smooth, PA11 Onyx, Flexa Grey. It is also compatible with the whole solution and accessories. Now you can buy them in 6kg steel eco-friendly containers that are compatible with Sinterit Solution accessories like ATEX Vacuum Cleaner and Sieve. The old 2 kg bottles are also available.
It is not usual to leave the top management job in one of the best companies in the interior outfitting branch. Especially after working there for 29 years. The decision of starting a company that produces 3D printing plastic parts using the laser sintering process may seem crazy, but Stefan Radau is the one who did it.
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.
Sinterit, European based manufacturer of the most available SLS 3D Printing Solution is officially entering the US market. Thanks to the cooperation with 3D Herndon, the Polish producer will provide access to maintenance services in the US, as well as training in 3D Herndon headquarters in Virginia.
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.
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?
