Question 1

Is the PA12 powder recyclable?

Accepted Answer

Yes, PA12 powder can be reused by sifting and mixing it with fresh powder. The software calculates the required amount of fresh powder to add, typically 30% fresh powder and 70% used powder. Note that Flexa powder is 100% reusable directly after printing and does not need to be refreshed.

Question 2

Is​ ​the​ ​powder​ ​recyclable?

Accepted Answer

Yes, you can reuse the once used 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. This applies only to PA12 powder, because the Flexa powder does not need to be refreshed and is 100% reusable directly after printing.

Question 3

Is the powder material harmful?

Accepted Answer

The powder material is generally safe, but it is recommended to wear protective glasses and a mask while handling it to avoid inhalation or contact with eyes.

Question 4

Is​ ​the​ ​material​ ​harmful?

Accepted Answer

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

Question 5

Can I print with white powder using the Lisa printer?

Accepted Answer

No, the Lisa printer is equipped with a laser that is designed for black powder sintering. It cannot sinter white powder as it requires a different laser wavelength.

Question 6

Can​ ​I​ ​print​ ​with​ ​white​ ​powder?

Accepted Answer

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.

Question 7

How​ ​to​ ​store​ ​the​ ​powder?

Accepted Answer

Due to its hygroscopicity, the powder absorbs the moisture easily. It 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.

Question 8

How​ ​to​ ​store​ ​the​ ​powder?

Accepted Answer

Due to its hygroscopicity, the powder absorbs the moisture easily. It 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.

Question 9

What kind of maintenance is required for optimal performance?

Accepted Answer

Regular maintenance is essential for optimal performance. This includes cleaning the laser protective glass, pyrometer glasses, wiping the recoater rods, and lubricating the recoater bearing before each printing process.

Question 10

What​ ​kind​ ​of​ ​maintenance​ ​should​ ​I​ ​provide?

Accepted Answer

Providing a 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.

Question 11

Do I need any external software to run the Sinterit printer?

Accepted Answer

No, you do not need any external software to run the Sinterit printer. The dedicated Sinterit Studio software allows you to design the printing process and operate the machine. Additionally, Netfabb software is compatible with the printer.

Question 12

Do​ ​I​ ​need​ ​any​ ​external​ ​software​ ​to​ ​run​ ​the​ ​print?

Accepted Answer

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

Question 13

What​ ​is​ ​powder​ ​sieve?

Accepted Answer

It is a device having 2 main goals: 1. to help mixing used powder with fresh powder, to receive print-ready material, and 2. eliminating little clods and lumps appearing during printing process to give the used powder appropriate looseness again.

Question 15

Why​ ​we​ ​need​ ​a​ ​sandblaster?

Accepted Answer

In sand blaster you remove the remainings of powder elements sticking to the print after first cleaning with brushes. You can compare it to washing the print in water, however sandblasting is way more efficient. In practical terms, sandblaster is necessary to get the best results and make the postprocessing run smoothly. Sandblaster is a common tool so if you own one already, you do not need to order it. Abrasive is 0.2 mm glass balls, - nozzle is 4-6 mm diameter, - working pressure is 5-8 bar. Sand blaster comes without an air-compressor (saving on shipping costs for you), so you would need to get equipped with one unit as well (recommended capacity: 290 L/min).

Question 17

Can​ ​Lisa​ ​print​ ​with​ ​metal?

Accepted Answer

Currently Lisa supports 2 materials: 1. PA12 - material suitable for printing very detailed objects 2. Flexa Black (TPU) - rubber-like for prototyping We do not support metal materials and currently we are not planning to change that in the nearest future.
