The Different SLS 3D Printers on the Market


Selective laser sintering – or SLS – technology is based on the fusion of a plastic powder using a laser. Historically, the process was relatively inaccessible because the machines remained expensive and quite hard to comprehend. But in recent years, the market for SLS 3D printers has opened up, with several so-called desktop solutions that facilitate the integration of additive manufacturing. Today, SLS is widely used by the automotive, consumer goods, design and medical industries. More materials have also been developed – like the classic PA11, PA12, TPU or even PP. In any case, the process is prized by many professionals and manufacturers, which is why today, we are taking a closer look at the main SLS 3D printers on the market: Who are the manufacturers behind these solutions and what features do the devices have? The machines, both desktop and industrial, are listed in alphabetical order.Get more news about china sls 3d printer,you can vist our website!

Founded in the United States in 2011, Formlabs develops professional 3D printers at affordable prices. The company became known for its stereolithography solutions, but since 2017 it has announced its entry into the powder sintering market, which it made a reality in early 2021 with the launch of the SLS Fuse 1 3D printer. This machine is capable of printing nylon (PA12 and PA11) parts with a minimum layer thickness of 0.1 mm and a maximum print volume of 165 x 165 x 320 mm. With a relatively low price, it offers users the possibility to manufacture and produce prototypes within their own company. Since this initial successful launch, Formlabs has announced a second SLS 3D printer, the Fuse 1+ 30W, which is intended to be faster but also compatible with carbon fiber-filled nylon.

Wematter is a Swedish manufacturer that has developed a desktop SLS 3D printer called Gravity. Thanks to its compact design, it fits perfectly into any working environment and is CE marked for use in an office, laboratory, workshop, or hospital. Gravity offers a print volume of 300 x 300 x 300 mm and a speed of 12 mm per hour. It is equipped with a touch screen and a HEPA air filtration system to guarantee a certain level of safety for the user. The user can also count on optimized management of materials (PA11 and PA12) thanks to a patented system that allows to store and recycle the powder directly inside the machine. Finally, you should know that this 3D SLS printer can be accompanied by a complementary machine, Atmosphere, which controls the interior of the printing chamber in order to improve the final properties of the parts.

Sinterit is a company founded in Poland in 2014, which is specialized in the development of SLS 3D printers. In 2015, the company introduced its first desktop solution with SLS technology called Lisa. In the new and updated version of the printer, Lisa Pro, Sinterit added new features. It incorporates a new nitrogen atmosphere system in the chamber, which prevents oxidation in the printing process and thus improves the quality of the printed parts. In terms of materials, it offers compatibility with two polyamides, four elastomers, and polypropylene, in addition to PA12 Smooth and PA11 Onyx. It uses a 5W diode laser and its printing volume is 73% higher, reaching 150 x 200 x 260 mm. Besides that, it features Sinterit Studio: An integrated software that helps the user with the printing process. This printer model is perfect for the most demanding users who need higher print volumes or nitrogen atmosphere.

Sintratec is the leading manufacturer of 3D printers in Switzerland and is specialized in the development and production of SLS 3D printers. The Sintratec S2 features automated processes and 3 modules: the laser sintering station (LSS), which consists of 8 heating zones allowing for high-quality surface finishing, the material core unit (MCU), and the material handling station (MHS). It also has an integrated 4K camera for remote 3D printing observation and a large touch screen for intuitive control of the printing process. The maximum print volume is 160 x 160 x 400 mm and it is compatible with materials such as PA12 and TPE. This all-in-one solution by Sintratec reduces downtime and allows for quick material changes and cleaning.
