Sinterit Lisa Pro: 3D printer with enlarged printing chamber


Sinterit Lisa Pro is an improved version of the desktop 3D printer Sinterit Lisa, produced in Poland. The article provides an overview of the technology: its characteristics, printing samples, implemented innovations, equipment.

Overview of Sinterit Lisa Pro

Sinterit Lisa Pro works using Selective Laser Sintering (or SLS) technology. This is selective laser sintering, suitable for creating small parts and prototypes from synthetic powder. The essence of the technology is the sequential sintering of layers of powder material using a high-power laser.

The SLS makes it possible to produce models with a smooth surface and a high modulus of elasticity. Supporting structures are not required during printing – this helps to get rid of layering of parts. The method has existed since the mid-1980s, but it was only introduced into the world of 3D printing in 2014. The pioneers were representatives of the Polish company Sinterit.

Desktop printers from the manufacturer from Poland offer the user good functionality at a low cost.


Sinterit Lisa Pro model entered the market in 2019. From its predecessor, the desktop printer with SLS technology is distinguished by a larger print chamber and an integrated argon or nitrogen supply. All objects in the printer are printed layer by layer, by laser beam sintering of polymer powder.

The material itself, from which the blank is made, serves as support. There is no need to put additional bridges between the elements of the part being prepared. After printing the shape of the part is obtained in any way, it is possible to create mobile mechanisms. The number of parts is limited only by the size of the chamber.

Sinterit Lisa Pro has two main innovations that distinguish the technique from its predecessor:

  • an enlarged print chamber;
  • built-in inert gas system.

Important! Professional version of the desktop 3D printer with SLS technology allows you to print and large models. The width, height, length can reach 32 cm in diagonal arrangement of the object.

Sinterit Lisa Pro is a printer with a built-in system for supplying argon or nitrogen into the printing chamber. This feature displaces atmospheric air from the space and significantly expands the choice of materials with which to work. Modern polymer powders are used for printing to ensure the strength and rigidity of the prints.

Main features

The Sinterit Lisa Pro is a desktop 3D printer that used the technical foundation of its predecessor to develop it. In the 2019 model of the Pro class, the following aspects have been refined.

Improved temperature control

The housing with steel elements provides good thermal insulation and makes maintenance easier. A metal insert protects the seals from premature wear and tear.

There are notches on the 3D printer’s lid. They fit snugly and allow the pyrometers to accurately detect the temperature in the printing chamber. This property ensures that the material is processed in the correct conditions.

Updated Reliability System

The Sinterit Lisa Pro features a glass in a sealed frame. This sheet protects the laser from damage and can be replaced if necessary and continue to use the technology. A new locking system is used to set the temperature in the chamber at the optimal level. It prevents heat loss.

Simplified maintenance system

The heating elements are easily accessible by the user at all times. The front panel is designed in such a way that the cleaning process will be easier. The housing can be disassembled in a few minutes for further transport of the device. 3D-printed latches allow the user to reassemble the frame themselves.

A special hole is designed for cleaning polymer residue.

Working with the exterior

Hinges and a new lock are provided for safer operation. The on/off button is located on the side. The rubberized feet do not slip on the surface, and the overflow tray has been increased by 10% in volume.

Thin Layer Printing

The Sinterit Lisa Pro is suitable for thin layers with a thickness of 0.075-0.175 mm. This ensures precision in machining parts. Printing accuracy in XY axes is improved: it is from 0,05 mm.

Increased model dimensions for printing

You can create large parts inside the chamber. Diagonally they can be as large as 31.6 cm, which greatly extends the scope of the device.

Specially developed Sinterit Studio software

To work with the 3D printer, the developers created Sinterit Studio – software that regulates the work of the equipment. It allows the user to set the parameters of the workpiece, determine the thickness of the layer and the location of the model inside the chamber.

Through the program, it is possible to control the work of all the printers in the access area. To do this, they need to be synchronized with the software, and the user can monitor the printing process. The file ready for printing is transported to the memory of the device via a flash drive or Wi-Fi connection.

Touch screen for operation

Menu items are provided for starting and controlling printing, cleaning the printer, and activating the accelerated mode. The touchscreen display shows progress information and displays errors.

The temperature in the chamber reaches 190 oC. The device works with polymer powders.

  • spatula for the powder;
  • plastic measuring cup;
  • metal sieve;
  • brand-name cup;
  • Sinterit Studio software manual;
  • user manual;
  • Spatula for powder extraction;
  • flash drive with Sinterit Studio software;
  • start key;
  • stylus;
  • a brush to clean the tanks;

Who is suitable for whom?

Spheres of use of 3D-printer Sinterit Lisa Pro are many. Among them:

  1. Fashion design and sewing. Melinda Bam, owner of Bambshell, created a line of swimwear decorated with three-dimensional details. They were made on a printer using powdered materials;
  2. robotics. High detailing allows models and prototypes to be created with clearly delineated exterior features;
    architecture and design. The printer can be used to prototype objects and consider possible weaknesses in advance;
    heavy industry. The device is designed for single or series production of parts;
  3. medicine. The printer can be used to create prototypes of prosthetics, to carry out projects of any complexity.
    The Polish model from Sinterit is also suitable for use in jewelry, the military-industrial sector, foundries, etc.

What materials are used?

Sinterit Lisa Pro not only works with free-flowing polymer materials. Elastic Flexa Black, TPU and thermoplastic polyurethane can also be processed. This raw material is suitable for the production of rubber-like parts. The device can process Flexa Grey, a material that provides increased flexibility.

The printer supports all SLS powders produced by Sinterit.

Important: If not all of the powder was used in the printing process, it can be used for the next session by adding a new powder to it. Approximately 70% of the RA12 and RA11 powders can be reused.

Getting ready to work: the basics

To start the printer, you need to press the power button and turn the special key. Before printing, you must wipe down the guides and inspect the chamber for foreign parts.

A respirator and gloves are mandatory when loading material into the compartment. The powder is aligned automatically. After that, the user needs to close the lid.

Models to be made on the Sinterit Lisa Pro are first created in the proprietary Sinterit Studio software. The slider is easy to use and has uncomplicated settings. The user selects the material, the location of the model in the chamber and the height of the layer.

Important! Objects in the chamber should not overlap and go beyond the allowable printing area.

After the user has created the desired model, it is transferred to the memory of the device via Wi-Fi connection or flash drive. The user presses the Start New Print button on the touch screen to begin printing. Available files for printing will appear in the list. You need to select the desired one.

Before printing the printer will warm up the camera for about an hour and a half. This is an important parameter for the calculation of the model production time.

The process of operation of the device can be monitored on the LCD screen: information about the readiness of the object is displayed on it. You can assess the situation in the chamber through the transparent cover on top of the housing.

The ready part is taken out with a special device. After that it is sent for post-processing. First the user cleans it from the powder with a metal brush, and then it is further processed in a sandblaster.

The manufacturer insists that there is no need for initial calibration once the device is assembled. The device is ready to work without additional measures.

Sinterit Lisa Pro is a printer from the Polish manufacturer, which became an improved version of Sinterit Lisa.
