Frequently Asked Questions
WHAT IS A REFRESH RATE?
- In the context of Sinterit products, refresh rate is the ratio of the minimum amount of fresh powder needed in a mixture of material used in an SLS 3D printer. The lower the refresh ratio, the better the cost-efficiency of the material.
HOW DO I REUSE USED PP POWDER?
- Reuse leftover PP powder on your next print by adding 50% of PP Fresh Powder. By mixing 50% used PP with 50% PP Fresh, you will create a cost-effective, 100% print-ready PP powder.
WHAT IS THE DIFFERENCE BETWEEN “Fresh” POWDER AND “Starter” POWDER?
-
Powder Type Condition Description Starter Print-Ready Powder that's ready to print. (i.e. no need to mix used and fresh
powder, it's ready to be poured into the machine and start printing)Fresh Fresh Powder that's for refreshing the powder. Mixing this with Used Powder
will turn it into Print-Ready.Used Powder leftover from printing, present in overflow bin or remaining
after printout cleaning.
HOW DO I MIX "Used" and "Fresh" POWDER?
- Powder Handling Stations or a Powder Sieve can help mix used and fresh powders.
- The amount of needed fresh powder is automatically calculated by the 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.
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)
DO I NEED AN ATEX VACUUM CLEANER TO CLEAN POWDER?
- Yes. SLS polyamide powder used for 3D printing is considered particulate matter because of its size. Polyamide powder particles are generally 40 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.
