About Sinterit

Source: facebook.com/pg/Sinterit

Sinterit is a major Polish SLS 3D printer manufacturer. The company was founded in 2014. The main purpose of Sinterit is to create advanced, yet practical 3D printers based on SLS (Selective Laser Sintering) technology. They claim that it could drastically change the world of manufacturing.  

SLS technology is a new step in the development of 3D printing. It allows you to produce parts that cannot be created using FDM (Fused Deposition Modeling), the most popular method on the 3D printing market at the moment. Lisa and Lisa Pro, the company’s signature 3D printers, are well-known and loved all over the world. In the six years of the company’s existence, Sinterit has collected a large number of various Polish and European awards such as CD3D: The Best Polish 3D Printer of 2015 and Best desktop SLS 3D Printer - winter, spring, summer and fall 2018 according to All3DP.

SLS 3D-printers

As we’ve already said, Sinterit specializes in the production of 3D printers based on SLS or selective laser sintering. This technology is implemented by sequentially sintering layers of powder material using high-power lasers. Since the powder material, which surrounds the model during the process of printing, serves as a kind of support for the model, there is no need to create any special supporting structures or jumpers between the elements of the printed part.

Sinterit’s Lisa is one of the most affordable desktop SLS 3D printers available on the market. The main feature of the model is the ability to simultaneously print out several different parts, including ones that are not connected to each other and those imbedded in each other.

The printer is equipped with a 5-Watt laser print head. In addition to that, it has a microcomputer that enables autonomous wireless printing. The device also has an built-in camera and a touch screen which make it possible to monitor the printing process.

PA materials are polyamide-based, one of the most well-known PA materials is nylon. Flexa materials are based on thermoplastic polyurethane.

  • PA11: the most common polymer for SLS, is characterized by a small particle size, which gives greater surface smoothness.
  • PA12: high-strength polyamide that can withstand loads of up to 41 megapascals and elongation at break up to 13%.
  • Flexa: material with increased softness and elasticity.

Powder particle size, nanometers:

  • PA11: 15-76, average - 40
  • PA12 Smooth: 20-100, average - 38
  • Flexa Black and Flexa Grey: 20-105

 

Software

Sinterit offers its own 3D modeling software, which helps to create models for 3D printing. The program is called Sinterit Studio and it is an ideal tool for building 3D models of any kind. On top of that, it allows you to monitor the state of the printer from the beginning to the end of the printing process and select the necessary amount of material. With the help of this program, you can not only create your own projects, but also upload existing projects in the wide range of file formats: STL, OBJ, 3DS, FBX, DAE, 3MF. In addition to that, in 2019 Sinterit introduced wireless communication with printers via Wi-Fi. 

At the moment, the company offers four versions of the program, each of them has a slightly varying feature set:

How you can use Sinterit

World’s first 3D printed theatrical costume

As part of her final project at the Royal College of Art in London, fashion designer Mingjing Lin tried to combine traditional fabrics and 3D technologies. She created a series of unique costumes for the Beijing Opera House.

Source: sinterit.com

Though the costumes are very flexible, they are capable of retaining their shape perfectly, which is practically impossible to achieve when using classic cotton and silk. 3D printing technologies turned out to be a perfect fit for the task. Using the Sinterit Lisa printer and the Sinterit Flexa Black powder, the design team managed to create costumes that follow the actors' movements without constricting them.

The texture of 3D fabrics differs from traditional costumes. These unusual materials gave a completely new quality to the costumes. This was sure to attract new listeners to the show, who were amazed by the new innovative costumes, that were quite unique for traditional Chinese Opera.

 

Military eyeglass case

When the design for this military eyeglass case was in the process of development, the main challenge was to create an individual design with a strong structure. One of the main priorities was to design a one-piece product, since the absence of connecting elements could significantly increase the durability. Using the new Sinterit Lisa Pro and PA11 Onyx powder, it was possible to create a prototype that meets these requirements.

Voice recorder spare details

Source: sinterit.com

The Polish radio station Radio Krakow has been using the same NAGRA Ares M voice recorders for more than ten years. It’s safe to say, that with such a long-term operation, the issue of lack of spare parts is almost inevitable. In this case, the battery slot covers were the weak spot. It’s a well-known fact that mechanical fasteners are fragile. But considering that the devices still worked perfectly well, the station staff decided to find an alternative to buying new voice recorders and contacted Sinterit.

The challenge was to create a perfectly sized cover, that wouldn’t affect the recording and playback of audio.

Source: sinterit.com

The size of the cover and its elements had to be as accurate as possible. The best solution to this task was to use SLS technology and PA12 Smooth powder. The second aspect was the printing time and the number of iterations. Since SLS technology allows to fill the print bed with a great number of such small models, it is possible to print quite a large amount of different prototypes in a single session. This way, you can test out several different concepts and options at once.

This is a great example of another interesting application of SLS technology — manufacturing of spare parts. The ability to not only create prototypes of new products, but also to change existing concepts, can have a significant impact on the production of fasteners and enclosures for various devices in the future.

 

Conclusion
