Ideal place for Lisa is a lab\workshop or production area because, although it is small, still is the machine. If you used to have an FDM or SLA printer and you didn’t have problems operating it within the office environment, the same will be with Lisa.  It could surely work in the office area.

It is quite simple. The main action you need to perform is to put the powder in and out of the printer. Lisa is a kind of a plug&play machine so it is very easy to operate.  As well as the slicer and the software. You will be lead step by step through the whole printing process.  To learn more, watch movies.

If the parts you are planning to print are bigger than the print bed, and the model is movable, you can try to arrange it in the way it will fill available space. If it is still impossible, you can divide it and reconnect after print. For a smaller object or fast delivery of single print, this is the most economical way of proceeding. Be aware that you are operating in three-dimensional space. While the printer will fully use the space described by X and Y coordinates covering it with the powder, the height (Z coordinate) is adjustable. If you are looking for cost advantages, position your model in a way in which its height is the smallest. This is one of the most important advantages of the “small” printing bed. The second is time. It is faster to heat it up and cool down after the printing than in bigger machines.

The advantages of small bed is:

• short heat up time and cool down time, 
• better quality of small elements, 
• it is more economical. Powder recovery system allows printing with up to 100% recycled powder if we are using Flexa Black. PA12 is suitable for printing after refreshing 30% of Fresh Powder, 
• powder refreshing rate: PA12 – 0 – 30 %, 
• the more stable process, more flexibility of applications,
• the small size of the whole printer requires small space, cost of maintenance and it is possible to move the printer around or even place it on your desktop.

It is up to 3 times cheaper to print on Sinterit Lisa → e.g. 100 pieces of small part battery lever printed in Sinterit Lisa costs 0,91 euro vs. 3,42 euro with an external service provider.

It is up to 3 times faster to print in-house than to order and wait for transport → e.g. Sinterit Lisa print time of one piece of breloc is 4h vs. up to 7 days of waiting time for service providers print.

• You are fully independent 
• You do not need to deal with paperwork (contract, NDAs etc.)
• You can keep confidentiality, your project is 100% secure
• You can see the result instantaneously and you can correct the design straight away (while at service provider you have to wait to see the effect and start the process again)

We have Powder Sieve and Sandblaster included in the set. It is a simple and reliable solution and can be used everywhere without any special environment. We are proud of our post-purchase support department and instructable materials (e.g. videos of the SLS printing process).

The quality of our prints is the same as in  big SLS machines. For small parts, it is even better. We have comparable parameters to big SLS, much better than other technologies.

This occurs due to material shrinkage and is difficult to eliminate in this technology if one edge is parallel to the base of the workspace. Especially if the flat surface is quite big. In order to avoid this, turn the model at least 20 degrees in the X-axis. The laser will print only a small part of the surface at one. If the problem persists, also rotate the model in the Y-axis.

Do not get discouraged. The printout will most definitely come out fine, as any dampness that may be contained in the powder because of its hygroscopicity will be immediately vaporized during the warm-up and printing of the machine. Spreading of the first layer will simply be slightly more onerous and take more time.

The recoater roller has probably stopped rotating. In order to fix this, apply two drops of oil to each of the recoater bearings (at both sides). Another reason that may have caused this is that the recoater’s transmission rope (responsible for its rotation) may have broken. You can notice that with an ease. Just check if one of the strands located by the recoater is broken. If so, replace it with the new one.

The gaps between the pins and the rotating elements are probably too narrow. Increase the gaps in the model. We recommend to keep at least 0.2 – 0.5 mm. Position the model parallel or perpendicular to the printing chamber.

The pyrometer sight glasses have probably not been cleaned properly. Use a cloth saturated with spirit to wipe them thoroughly. This should resolve the problem. If you clean the pyrometer glasses properly (and it still doesn’t help), you can try to decrease the temperature offset.

• If the model is dense and the cross-section has a large area, please rotate the model so that the cross-section decreases.
• If the model has some details, please orient the detailed surface upward. The detailed surface will be sharp, while the bottom surface will be smooth.
• If the model has round holes and features, the shape will be most accurate if the surface is positioned flat.
• If the model contains movable parts, please position it perpendicular/parallel to the printing chamber.

Be sure to put the model within the green area/increase the temperature (cold zone)/ increase the laser power if the layers are visible.

Yes. It is one of the most important future. You can reuse the old powder by sifting it and mixing with the fresh powder. The software calculates the amount of Fresh Powder you need to add and mix with the used powder – it is about 30 % of Fresh Powder and 70 % of used powder

Our powder has CE certificate. We also provide Safety Data Sheets for all materials. There are no special legal obligations protecting from powder handling. The powder is not toxic. It is similar to dust.

What’s more: The most harmful particles are UFP (ultrafine particles) – which are emitted by FDM printers. Their harmfulness is similar to cigarette smoking. Our particles are much larger than 40 microns, so it is difficult to lift them to air. Besides – the printing process is closed inside of the machine. We recommend small masks during refilling and cleaning process

Print Ready Powder –  the unsintered PA12 Smooth powder that remains after the printing and print’s cleaning process. Suitable for printing after refreshing by 30 % of Fresh Powder.

Fresh Powder – PA12 virgin powder, used for refreshing, needs to be mixed with the Print Ready Powder in correct proportions.

Powder refreshing rate for  PA12 is 30 %

For Flexa Black – 0% – unsintered Flexa Black powder that remains after the printing and print’s cleaning process is suitable for next printing without refreshing

The powder is itself non-toxic. After sintering, we get  (PA12 Smooth) 100% safe material for health. With extremely low porosity. We can sterilize printed models under 100 [ o C]  temperature

• The main material used in SLS printing is Polyamide (Nylon)  PA12. Melting temperature of PA12 (or Nylon 12) is 171 Celsius degrees. It’s also highly resistant to chemical substances, like acetone, petrol, glycerine, methanol, etc. PA12 is resistant to UV irradiation as well. To compare, materials used to print with FDM has rather a poor chemical resistance, as well as materials, used in SLA printing. 
• We have also FLEXA Black – rubber-like, elastic material

The powder has not been refreshed properly and has aged. Use new powder or add at least 50% of the so-called ‘Fresh Powder

The powder does not cause any risks. However, it is recommended to wear protective glasses and mask while working with the powder

No, any kind of a white powder needs a laser with a wavelength dedicated to sinter a white powder. Lisa has a laser that provides black powder sintering. 

Black color enables to use a laser of the different wavelength. 

Due to its hygroscopicity, the powder absorbs the moisture easily, which has a bad impact on the mechanical properties of the material. Thus, the powder should be not exposed to the environmental conditions for a long time. Keep it closed tightly in the provided containers

Providing regular maintenance will make the performance better. Clean the laser protective glass, pyrometer glasses, wipe the recoater rods and lubricate the recoater bearing before every printing process.

Due to overloads and high temperatures the recoater wire may wear out after many prints. It is a consumable part and the replacement is very easy – please see the tutorial below.

No, the dedicated Sinterit Studio enables you to design the printing process and run the machine. The Netfabb software also collaborates with the machine as well.

• 64-bit processor
• Windows 10 or higher,
• Minimum 1 GB of disk space,
• Minimum 2 GB of RAM,
• Graphics adapter compatible with OpenGL 3.0 or higher.
• File type STL, OBJ, 3DS, FBX, DAE, 3MF

Please take a look at the guide section “how to set the parameters”

• If the model is dense and the cross-section has a large area, please rotate the model so that the cross-section decreases.
• If the model has some details, please orient the detailed surface upward. The detailed surface will be sharp, while the bottom surface will be smooth.
• If the model has round holes and features, the shape will be most accurate if the surface is positioned flat.
• If the model contains movable parts, please position it perpendicular/parallel to the printing chamber.

Sometimes you can see that the recoater arm is vibrating when moving (eg. during levelling procedure). This might be caused by insufficient oiling of the recoater guide shaft. To make sure that the recoater linear bearing is moving smoothly:

• turn the printer on
• go to the Advanced mode and then to the Mechanics tab,
• move the feed bed down, (approx. 2cm below the printing chamber level)
• start the levelling procedure
• apply the silicone oil on the recoater guide shaft generously.
• repeat applying through a few recoater passes

Cleaning the recoater arm and replacing the recoater cord might also help minimize recoater arm vibrations. (see “How can I replace a worn-out recoater cord?” and “How can I clean the recoater arm?” in the Maintenance section)

If the issue persists please contact Sinterit Support.

Error #202 indicates a low oxygen level in the room. Make sure there are no leaks on nitrogen tanks and the nitrogen flow is cut off. Ventilate the room for at least 2 hours.

If the issue persists please contact Sinterit Support.

Error #84 indicates a communication issue within the printer. This error doesn’t affect the print quality and should go away after the printer firmware update. Please see “How to update the printer firmware?” in the Maintenance section.

If the issue persists please contact Sinterit Support.

If the printout doesn’t meet your expectations, first check if the models’ geometry and placement is correct. You can download the “How to position models” tutorial from the Sinterit website.

If the geometry and positioning of the models are correct, check if:

• all of the short infrared heaters are lighting up,
• the recoater cord is in good condition,
• the powder is in good condition,
• the pyrometer window modules are clean
• the recoater arm is moving smoothly

If the issue persists please contact Sinterit Support.

Some rendering methods might have problems working with Windows PCs which cause the models in Sinterit Studio not to appear correctly. In order to change the default rendering method:

• go to the Setting tab and select Display settings
• choose OpenGL or OpenGL ES to see which rendering method works best with your PC.

If the issue persists please contact Sinterit Support.

Sometimes, when exporting your 3D models as *.stl files an error may occur which causes the file to save with a gap between some polygons. Sinterit Studio cannot print such a file. If you have a faulty *.stl file:

• go to Microsoft 3D Builder (you can download this app for free from Microsoft Store on your Windows 10 PC),
• open the *.stl file,
• click import model in the top right corner,
• an error message will appear in the bottom left corner
• click fix to fix the problem the process might take a short while
• save the new *.stl file

If the issue persists please contact Sinterit Support.

• Possible reasons are:
  • UDP traffic is being blocked (UDP is being used for discovering the printer in the network),
  • port 8888 is being blocked (it is being used for communication),
  • the printer has to be in the same subnet (it’s hard to judge by the IP),
  • there is no DHCP server set in the network.

  If you checked all of the above you can check the connection via ping

  • launch the command window in Windows (Start –> cmd) and type: ping
  • after a space type IP address of the printer (eg.: ping 192.168.0.1) and press Enter

  If you can successfully ping the printer, contact the administrator of your network.

  If the test fails you can try connecting via phone:

  • launch Wi-Fi access point on your phone.
  • Connect your PC (with Sinterit Studio installed) and the printer to your phone
  • Check if the Sinterit Studio can discover the printer.

  If you can successfully connect to the printer, contact the administrator of your network.

  If you have any difficulties contact Sinterit support.
