Sinterit Lisa X In-Depth Review: Fast and Compact SLS 3D Printer

https://top3dshop.com/product/sinteri...

Hi everyone! This is Top 3D Shop, and in this video, we will tell you about the Sinterit Lisa X SLS 3D printer.

The Polish manufacturer Sinterit introduced its first compact 3D printer Sinterit Lisa in 2014. Since then, the company has delivered several hundred of these SLS systems, which operate in more than 40 countries. The company’s clients include BMW, Bosch, Autodesk, Toyota, and a number of major universities. Besides, Sinterit Lisa won many international awards as the best desktop SLS printer.

In 2019, Sinterit entered the professional industrial segment with two new models — the Lisa X and NILS 480.

Selective laser sintering, or SLS, is a 3D printing technology used to create functional prototypes and small batches of products using synthetic powders. It is based on layer-by-layer sintering of powder materials.

The technology makes it possible to create durable products with high elasticity and quality surface.

In a single print job, an SLS printer can produce highly accurate functional objects consisting of moving parts with complex internal geometry.

Most importantly, SLS eliminates the need for support structures — the powder itself serves as a support for overhanging elements during printing. Once the process is complete, the user simply cleans the model from the powder, and it is ready for use.

In contrast to the previous professional model Lisa Pro, version X has a larger build volume: their maximum dimensions are 110 x 160 x 245 millimeters and 130 x 180 x 330 millimeters respectively, or 4.3 vs 8 liters.

When placing an object diagonally across the print volume, the Lisa X can create parts up to 40 centimeters long. This picture shows the volume of Sinterit Lisa Pro holding 48 finished oil caps, while the build chamber of Lisa X holds 72 similar products.

Let's compare the print volumes of machines of a similar segment from other manufacturers. The Sintratec S2 has a cylindrical chamber with a diameter of 130 and height of 360 millimeters, in the Formlabs Fuse 1 it is 165x165x300 millimeters, or 4.8 and 8.2 liters respectively.

As for the maximum height of the object, the Sinterit Lisa X allows creating objects up to 40 centimeters long when placed diagonally, and the Formlabs Fuse 1 and Sintratec S2 — up to 38 centimeters.

Apparently, the choice of a device depends on the tasks. The Lisa X offers a good balance between the requirements of medium batch production and the manufacture of large prototypes.

The second difference is that Lisa X uses a galvanometer while the Lisa Pro employs H-bot kinematics. So, for a 100x100 millimeter square outline, the printhead has to move along this path. The printhead in Lisa X remains stationary, with the laser guided through a system of mirrors, which allows increasing the print speed by 10 times.

The Sinterit Lisa X carries a 30 Watt diode laser, 6 times more powerful than that in the Lisa Pro and 3 times more potent than the laser modules in the Sintratec S2 and Formlabs Fuse 1. This advantage expands the versatility of the Lisa X.

Another important difference between the Lisa Pro and X is connectivity: the new model offers not only Wi-Fi and USB options but also Ethernet — a mode best suited for organizations with stringent security protocols.

The Sinterit Lisa X retains all the best features of previous models. This includes an integrated system of supplying gas mixtures in the build chamber to create an oxygen-free environment. The use of inert gasses such as argon or nitrogen makes it possible to utilize the latest consumables, like Onyx PA11 Carbon Fiber polyamide, to produce parts which are as strong as aluminum.

The manufacturer also offers the proprietary Sinterit Studio slicer, which not only supports well-proven profiles for its materials, but also allows you to modify 32 printing parameters and experiment with third-party consumables.

One of the most useful features of Sinterit Studio is Auto Nesting. It helps to use the entire print chamber most efficiently by automatically placing models and also makes sure that parts don't overlap each other.

In addition, Sinterit offers a complete ecosystem of solutions that includes cleaning and post-processing stations for finished products with a full range of accessories, as well as a powder handling station.

The Sinterit Lisa X comes fully assembled and ready to use, it is transported with an impact-resistant mobile case.

The printer is supplied with everything you need for the operation and maintenance of the unit.

The outer dimensions of Sinterit Lisa X are 650x610x1200 mm, and it weighs 145 kg.

After the printer is turned on for the first time, there are a few simple calibration and initial setup procedures to go through. All necessary steps are described on the printer's LCD display and accompanied by informative videos.
