Open parameters

We are enabling you to controll full spectrum of parameters of your SLS printer. You can not only create new material profiles, but also adjust to your needs any material profile from Sinterit offer. Thanks to the inert-gas control system (Lisa Pro, Lisa X) you can also experiment with third-party powders outside of our offer, opening up a wide range of possibilities

What is the refresh rate?

It is the ratio of a minimum amount of fresh powder needed in a mixture of material used in an SLS 3D printer. A lower refresh ratio means better cost-efficiency of the material.

How does it work?

The amount of needed fresh powder is automatically calculated by our software and shown on the printer screen after the print job is finished. Just add shown amount of material into the mixing cycle of used material and you can start your next job with refreshed material

FAQ

How should I store the printing powder?

Store the powder at room conditions ( ~23°C and 50% humidity – the lower the 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 ensure they don’t end up in the printer when you are filling it)

What is the difference between powders?

The differences between the powders can be found in the table below.

What is the difference between “Fresh” powder and “Starter powder”?

Starter powder is basically a print-ready powder.

In Sinterit we distinguish three powder conditions: print-ready, used, and fresh.

Used is a type of powder that you get after the printing, present in overflow bin or remaining after printout cleaning.

Fresh is a type of powder that is being used for refreshing the powder. After mixing this powder with used powder you will receive print-ready.

Print-ready is a type of powder that you can simply pour into the printer and start printing.

Although printing using Fresh is possible it’s not economically optimal therefore Sinterit printers are optimized for using a refreshed (print-ready) powder.

Why do I need an ATEX vacuum cleaner to clean powder?

SLS polyamide powder used for 3D printing is considered particulate matter because of its size. Polyamide powder particles are generally 40 micrometers or smaller. Powder vacuumed in an ordinary vacuum cleaner could cause an explosion.

Such materials are subject to labor regulations on air quality and occupational safety. The procedures call for appropriate maintenance of powders at work. Only certified industrial vacuum cleaners should be used for cleaning such materials. More information about the ATEX Vacuum cleaner can be found here.
