From different additive manufacturing technologies Dudek is especially interested in selective laser sintering (SLS) printers. There are several reasons.

First of all in SLS technology you can print almost any shape, without worrying about complicated geometry – says Piotr Dudek.

The freedom of creation is especially important. No matter if the internal or external structure of the element is complicated. His faculty already uses several powder based 3D printers from EOS, Zcorp and Sinterit.

The benefits of big machines are connected with their impressive print volume. If you need big parts printed at once it is hard to find other solutions. But there are also down sides as high price, difficult calibration and the need of special training for operators. It is also very expensive to print small parts, as you need to provide a lot of powder to start printing.

We are using the big EOS SLS 3D printer for a long time and we wanted to compare it with Sinterit Lisa, check the possibilities of it -says Piotr Dudek. In SLS technology every detail matters. The temperature of the printing chamber, powder distribution system, heating or laser moving mechanism are very precise and important features. We wanted to test if Sinterit’s device is the valuable solution. – adds Dudek.

One of the weak points of the big machines is that galvo laser steering system could be easily discalibrated during the transportation. Sinterit Lisa printer use gantry system so the printer could be pre-calibrated, which means that after taking it out of the box you don’t need to spend days on adjustments.

Another benefit is that you can use as little as one or two liters of the powder to start printing. It is a way cheaper solution, especially at universities, where you print a lot of different models for a large number of students and academics and it is not economical to print them separately on a big device.
