What is the refresh rate? 70% Recycled to 30% Fresh
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 it works
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
To start SLS 3D printing you need the powder starter pack. After that, you’ll only need to refresh the powder you own with fresh 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. 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.
Thanks to the inert-gas control system (Lisa Pro, Lisa X, NILS 480) you can also experiment with third-party powders outside of our offer, opening up a wide range of possibilities
