The main reason Somfy reached out for the SLS technology from Sinterit was productivity. Printing many pieces in one batch was a game-changer

Head of Jetson’s R&D

When we look at Lisa’s line of printers, or Sinterit at general compared to other companies, the two major things that we liked were the materials, that are open source, so we are not locked into one brand […]. We are able to look around the market and use a material that works best for the part.

It was the best choice for me to fulfill all requirements: possibility to print complex structures, price, speed, reliability.

Sinterit LISA is the most accessible means to produce precise constraint-free solutions to modern problems. The technology does what it says on the tin and the team at Sinterit is dedicated to working with their customers to achieve their objectives.

Peter Benthues

H. Gautzsch Firmengruppe

For a company at the beginning of an investigation, support from, and discussion with the technology experts is extremely beneficial. The LISA is one of the few economically feasible solutions in the first stages of any AM Strategy. At lower volumes, it is a perfect solution.

The FFF and SLA parts are a good choice to get a physical impression of the designs and to assemble rough prototypes. But when it comes to producing reliable prototypes to be verified in our fatigue tests or to send functional samples to our customers for validation, SLS is the only acceptable choice.

FAQ

How should I store the printing powder?

Store the powder at room conditions ( ~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 directly after 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 hours.
Put a few silicone absorbers in the container (but don’t add them to the printer)

Contact Sinterit support with your questions.

How are the powders different?

The differences between the powders are described in the table below.

SEE COMPARISON TABLE

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 2.5 micrometers or smaller. If vacuumed in an ordinary vacuum cleaner, the powder could cause an explosion.

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

Contact Sinterit support with your questions.

What distinguishes Flexa Bright powder?

Prints made using Flexa Bright are extremely elastic. Additionally, it can be colored, even in very bright colors, which is useful, for example, in creating visual prototypes.

Below there are approximate costs for some example models.

Be aware that the quotation assumes that there is only one piece printed. In SLS technology, the cost per part will be much lower with a higher number of elements printed at once.
