Sinterit

Sinterit Lisa Pro and Lisa are benchtop SLS 3D printers perfect for design and low volume production of detailed elements and movable parts. Their size and price enable small and medium enterprises to take advantage of the incredible possibilities of careful Laser Sintering. 

About Sinterit

We are a manufacturer of available SLS 3D Printing solutions. When we created our first small SLS 3D printer, Sinterit Lisa in 2014, it was a great challenge, as desktop SLS 3D printers did not as yet exist. And the game was afoot. After years we gathered the knowledge from Lisa users and the newly created market. That led us to introduce in 2018 the more advanced Lisa Pro.

Product Portfolio

Sinterit Lisa

Sinterit Lisa is the first-ever true benchtop-sized SLS 3D printer, the Sinterit Lisa. This compress machine managed to make SLS 3D printing more reachable and affordable, while still maintaining the high print quality that makes the technology so valuable in the first place. Bringing powder based SLS printing to the desktop, the NEW Sinterit Lisa New Generation has all the features users love about the original and some new enhancements Print. 

Sinterit Lisa Pro

Sinterit Lisa Pro is high precision, built-in nitrogen chamber benchtop SLS 3D Printer. It is new inherent software and easy to operate. It gives industrial quality and bigger prints. Because of the nitrogen chamber, we can experiment with a huge number of materials. We can take the advantage of the excellent print volume. The best solution for larger models, up to 316 mm crosswise, depending on the material.

Frequently Asked Questions

To be sure that the Sinterit powder is dry and ready for printing, You have to follow a few rules:

  • Store the powder in room condition ( ~23°C and 50% humidity – the lower humidity the better)
  • Always store the material in a sealed dry box/container.
  • Do not leave the container open.
  • Clean the machine right after the printing and store the material immediately after removing the print cake. 
  • Do not let the powder stay in the printer for more than a couple of hours.
  • Put a few silicone absorbers into the container (but do not forget about them when filling the printer)

The optimal moment to remove the print from the printer is when the temperature of the top layer drops below 40°C. It’s strongly recommended to remove the printouts within 48 hours after the end of printing.

It is very important not to use isopropyl alcohol on any parts of the printer. It might damage the pyrometer window module and discolor painted surfaces of the unit.

Regular alcohol-based window cleaner is recommended for the majority of surfaces. But pure (at least 95%) ethyl alcohol is recommended for the pyrometer window modules.

Using other solvents or cleaning solutions might damage the pyrometer window modules and affect print quality. 

When cleaning the printer with a vacuum cleaner remember to use a Sinterit ATEX-certified Vacuum Cleaner. Using uncertified vacuum cleaners may lead to starting a fire or explosion.

The best way to remove the melted powder residue on the walls is to use a very sharp blade – be gentle to avoid scratching the cylinder wall. You can also consider using a brass brush with soft bristles, that won’t scratch the surface of the cylinder walls.

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
